hile regulation is hailed as an ally in the efforts to raise the bar on energy efficiency and health, government officials, the very architects of regulation, speak of the need for a balanced approach. Too much of regulation and too soon, they say, could have a ripple effect across the entire manufacturing and supply chain, with the eventual cost of technological upgrades to match the needs of regulation, likely to be passed on to the customer; simply put, they say it is about affordability. For instance, a code that places a demand on all owners of existing buildings to re-insulate their structures or to retrofit the ducting systems, will likely be an insurmountable challenge for some. They simply will not be able to bear the cost of tearing down the existing ducting network and the likely disruption to tenants, who might choose to leave, thus depriving the owner of rental income. At the same time, a case can perhaps be made for the indispensability of regulation in certain circumstances. There will be those that will call for its enforcement, no matter the economic costs involved. The necessity, in their view, can come from new health concerns, say. At a recent roundtable on paints that we organised and conducted, manufacturers and consultants spoke of the use of anti-microbial paints in hospitals and debated at length on whether they ought to be also considered for residential and commercial buildings or not. Those in favour of a more democratic coating approach argued that all humans deserved the apparent benefits of antimicrobial paints. Likewise, a case could be made for the mandatory use of UV lamps to disinfect all fresh-airhandling units or in the ducting to disinfect the system. Much in the same way, a case could be made for mandatory installation of carbon monoxide sensors in residential units, especially kitchens, in order to prevent poisoning; it is mandatory to use the sensors in some countries. The dichotomy involving regulation is worth pondering. There is a need to find a sweet spot, with leeway as well as the tightening of the reins factored in, as per health or similar critical concerns, but it’s easier said than done. Finding the spot, though, would determine the success of a country in achieving its social, economic and health goals.

“Energy now is a strategic business issue” US-based Rockwell Automation, dealing in industrial automation and information, presented a paper on Energy Monitoring Solutions at the Middle East Electricity (MEE) and Solar Middle East, which took place in February at the Dubai International Convention and Exhibition Centre. Against this backdrop, Climate Control Middle East interacted with Raghu Prasad, Technical Consultant, Integrated Architecture, Rockwell Automation. We bring you the excerpts.

Could you share with us the salient points of the paper that Rockwell Automation presented at MEE? Billions of dollars are lost worldwide due to energy being wasted. Though the world is facing energy crisis, many do not give enough importance to conservation of the energy being wasted. The potential upside in saving energy will not only lead to financial benefits but also environmental sustainability. Energy now is a strategic business issue for all manufacturers. There could be many drivers for implementing energy management initiatives, such as reducing energy costs per unit of production, having transparency in the cost of manufacturing, increasing competitiveness in the market by producing at lower cost, lowering emissions, minimising risks of penalty or overbilling. It is not sufficient just to measure the energy being spent in a facility to provide a meaningful picture of the energy situation. Most energy monitoring solutions in the

industry have a standard feature. But we go further than just providing the energy information to the user by leveraging our Integrated Architecture to bind these energy data with process data, equipment performance data, planning data etc, to give a proper assessment of the situation. The energy information when contextualised with the production intelligence, will paint the right picture to help make better business decisions. In light of the increasing energy demand in the UAE, how do your products encourage energy efficiency and sustainability in facilities? Our solutions for sustainable production address three major corporate sustainability objectives through automation: • Energy conservation and efficiency • Environmental responsibility and resource management • Safety for workers, machinery, processes, and products

Could you share with us information on your products that have direct application in HVAC systems? Our HVAC sensors are designed for commercial and industrial HVAC and air handler applications. HVAC Humidity Transmitters are 4-20 mA current loop humidity transmitters, designed to provide precise signal accuracy with long-term stability in HVAC and industrial air handler applications. Our HVAC switches include differential airflow switches, low-limit temperature switches and AC current switches. Our differential airflow switch senses positive, negative, or differential air pressure, while the low-limit temperature switch provides a switched output based on the average temperature detected along a sixmetre (20 feet) capillary sensor. Our AC current switch activates a contact closure whenever the monitored primary circuit current exceeds 1.5 A. What steps has your company taken to educate its market regarding energy efficiency and power security? Yearly, we hold different types of activities to educate the market about energy efficiency and sustainability. Last month, we started conducting a technology seminar in Oman. And now it is on its second session in Qatar. Afterwards, it will move to Kuwait in May. Another significant event that we’ll hold this year is the two-day Automation University, which will be held in Dammam, Kingdom Saudi Arabia, by September. We also conduct Automation fairs in the United States, which are attended by participants worldwide. 

In line with its avowed objective, LG reportedly manufactures and promotes products with superior energy efficiency. Could you tell us about it? Also, are there LG HVAC products with “Energy Star Most Efficient” label? The Tropical Multi V Series, our flagship product, is touted to be amongst the most energy-efficient VRF technology since 2002. As a three-phase machine, these systems are not covered under Emirates Authority for Standardisation and Metrology (ESMA) regulation for now. The ESMA regulation stipulates on star ratings required for the single phase products entering and sold into the UAE. For HVAC products, ESMA currently is applicable only for windowand wall-mounted split units, which are primarily single phase. Such systems are evaluated based on their ability to meet the stringent Estidama regulations in the UAE and MEW regulations in Kuwait. We are listed in Estidama list of HVAC vendors. Our new line up from the South Korea factory, comprising ceiling concealed ducts, cassettes, ceiling suspended units and package units introduced last year is equipped with inverter compressors and R410A. It is said that LG increased the number of “Most Efficient” models available by 55% in 2013 from 2012. Did that include HVAC-related products? What R&D initiatives does LG employ to

Climate Control Middle East May 2014

create more efficient HVAC products? Considering HVAC products consume most of the electricity in a facility, any improvement in these products is bound to have a major impact on your electricity bills. Our LG R&D team has developed an auto-dust removal function in condenser units. This feature helps clean the condenser coils when the machines are unused for a long time. We have recently been recognised by the EPA for our commitment to protect the environment by manufacturing and promoting energy efficient products, as well as educating consumers on the important, positive effects that energy efficiency behaviours can have on the environment. Could you tell us about LG’s initiative to educate consumers on the positive effects of practices that encourage energy efficiency? Since its inception, LG Electronics Gulf FZE has always had a Training Academy for HVAC products in the UAE. This facility is used to share knowledge on our products with HVAC consultants, contractors and clients. Additionally, we conduct in-house technical seminars with the stakeholders of the projects from time to time. We also work towards imparting training to the technicians of HVAC installers on installation, testing, commissioning and trouble shooting of our specialised products.

ASHRAE releases ASHRAE releases new addition to Standard 105-2014 Datacom Series Revised standard helps compare building energy performance

SHRAE has released the newly revised ANSI/ASHRAE Standard 105-2014, Standard Methods of Determining, Expressing, and Comparing Building Energy Performance and Greenhouse Gas Emissions. Announcing this through a communiqué, ASHRAE said the revised standard supports commonality in reporting the energy performance of existing or proposed buildings to provide a consistent method of measuring, expressing and comparing the energy performance of buildings. According to ASHRAE, it also provides a common basis for reporting building energy use in terms of delivered energy forms and expressions of energy performance; for comparing design options; and for comparing energy performance in terms of energy resources used and greenhouse gas emissions created, both across buildings and for energy efficiency measures within buildings. “A standard method of measurement is needed in order to be able to compare one building’s energy use to another,” Keith Emerson Chair of the Standard 105 committee, said. The new edition of Standard 105 now includes procedures for going beyond site energy to calculate the impact of building energy use on primary (source) energy and greenhouse gasses, Emerson pointed out, and added, “To keep the standard flexible, a number of decisions are left to those who adopt it, including what should be calculated beyond site energy and the multipliers for those additional calculations.” ASHRAE gave the following details of purchase: The cost of Standard 105-2014, Standard Methods of Determining, Expressing, and Comparing Building Energy Performance and Greenhouse Gas Emissions, is $58 ($48 ASHRAE members). To order, contact ASHRAE Customer Contact Center at 1-800-527-4723 (United States and Canada) or 404-636-8400(worldwide), fax 678-539-2129, or visit www.ashrae.org/bookstore.

Provides updated liquid cooling guidelines for data centres

aying that data centre rack heat loads are steadily climbing, creating a need for liquid cooling solutions to reduce the volume of airflow needed, as well as lower processor temperatures for better computer performance, ASHRAE has introduced “Liquid Cooling Guidelines for Datacom Equipment Centers”. The recently published second edition also provides best practice guidance for implementing liquid cooling systems in data centres, ASHRAE added. ASHRAE gave further details: • Fourth in the ASHRAE Datacom Series and authored by ASHRAE TC 9.9., the guide bridges the liquid cooling systems by providing guidelines on interface requirements between the chilled-water system and the technology cooling system and on the requirements of liquid-cooled systems that attach to a datacom electronics rack to aid in data centre thermal management. • Also included are updated references and further information on approach temperatures and liquid immersion cooling, plus guidance on water quality problems and wetted material requirements. • It covers definitions for liquid and air cooling, as they apply to IT equipment, along with an overview of chilled water and condenser water systems and other datacom equipment cooling options. “There is an increasing interest in liquid cooled IT equipment at the rack, equipment and component levels,” Don Beaty, Publication Chair of Technical Committee 9.9., Mission Critical Facilities, Data Centers, Technology Spaces and Electronic Equipment, said. “There is also increased interest in reuse of the heat rejected from IT equipment. One of the more important changes to the second edition is the addition of supply water temperature classification.” Beaty claimed that the addition of liquid classes can have a similar effect on the industry as the creation of supply air temperature classes did, which was the critical enabler to the use of economisers in data centres. “There are five water temperature classes with the highest temperature class being >45 C (113 F), which opens up possibilities for using the rejected heat for building heating systems,” he explained.

inter interview SaFID

A wellrounded approach Round ducting systems score over rectangular when it comes to minimising air leakage or micro-organism build-up, says Jamal Jawhari, the CEO of SAFID Company Limited, while in conversation with Climate Control Middle East

Could you please give readers an idea of how you have developed as a company that is dealing in ducting systems? What technological innovations have you introduced over the years?

SAFID was established in 1979 in Riyadh, Saudi Arabia, as a joint-venture company between the Rahbani Group and the NOKIA company of Finland. SAFID started its operations and production with a clear objective to develop and manufacture air-distribution products based on the latest technological advancement and expertise in the field. Initially, SAFID manufactured spiral, round and flat oval ducts. Today, we have diversified into new products, including rectangular ducts, doublewall spiral and oval, industrial products, dampers, louvres, air terminals, VAVs, attenuators, grilles and diffusers, flexible ducts and air-handling units. This is all backed by more than 35 years of experience along with a state-of-the-art acoustic and aerodynamic laboratory that is led by our R&D department. 36

Leakage of valuable chilled air is a major issue. In the US, where studies have been conducted, buildings lose billions of dollars owing to leaking ducts, because that much more power is needed to replace all the chilled air that has been lost. How do you prevent leakages in your systems? Duct construction and the selection of the type of ducts to use play a major role in reducing or eliminating leakage. Duct construction is our core business, and we have adopted quality control and duct inspection procedures and measures on all ducts and products to meet and exceed requirements of specifications and standards. On the other hand, we always promote spiral ducts and round fittings in lieu of the conventional and traditional

Climate Control Middle East May 2014

We break down the HVAC system into stages, and we treat each stage alone to maintain the hygiene level of the system rectangular ducts. Spiral ducts are stronger and longer than conventional ducts. With lengths up to six metres, they can safely eliminate the risk of leakage, owing to the reduced number of joints. Traditional ducts come in lengths of

either 1.2 or 1.5 metres, which means they require thrice the number of joints required for spiral ducts. Our ducting systems, which come with Lindab safe gaskets, can withstand the highest of working pressures, along with SMACNA air leakage class 3, and meet NFPA-90A standards; they have also been UL-tested. They are also temperature-resistant, starting from -70 C to +150 C. They can withstand negative and positive pressures up to 3,000 pascals (12 in w.g.), resulting in a leak-proof performance. We are striving to convince our clients (consultants, contractors and project owners) to switch from the traditional rectangular to round ducting systems, owing to the commendable benefits of the latter, and not to mention the ease of installation and lower maintenance cost. In the case of regular conventional rectangular ductwork, it is necessary to go through factory-applied sealant on all longitudinal joints and on all transverse joints to avoid leakages. Also, usually the sealant is applied at the transverse joints on site after installation, when the duct is supplied without flanges. Sealant should not be

excessively used, as it will dry with time and leave the joint unsealed, which exposes it to substantial risk of leakage.

In view of frequent sandstorms in the GCC, and the porous nature of walls, sand – and also dust – tends to get into the built-environment and into the ducting systems. In combination

with humidity, the sand/duct particles harden to provide an ideal breeding ground for mould. Have you developed a technology to combat dust from lodging in the ducting system? Do you use filters as an integral part of your ducting system? And to combat microbes, do you retrofit

UV in your ducts?

We use sand-trap louvres and filters to prevent dust, sand and solid particles from penetrating the system (mainly for fresh air to mix with recirculated or return air). However, we break down the HVAC system into stages, and we treat each stage alone to maintain the hygiene level of the system. This procedure, of course,

depends on the project and the hygiene level required, since we have different products for such a treatment. For example, we use filters and UV lights at the air-handling unit stage, antimicrobial and selfcleaning panels in the duct system or a stainless steel duct system. We usually recommend the round system for hygiene reasons, since

Our lab was built to perform-test in accordance with ISO 7235 and ASTM E477-99 it has no edges and harsh corners, where fungi, bacteria and viruses can accumulate, as is the case with the rectangular system.

How do you eliminate noise created by air movement in bends in ducting systems? Do you integrate any special acoustic features?

Noise control in a duct system is not difficult to achieve, provided the basic noise-control principles are understood. Noise, by nature, is energy waves, and when it meets a soft, porous wall, the vibrating molecules penetrate the surface layer; they are impeded in their progress by the friction caused by their movement against the material fibre. The part of the energy that is, thus, absorbed is converted to heat in the material, and the rest is reflected into the room. For this, we have a selection of several acoustic products like the crosstalk, cylindrical and rectangular attenuation systems and acoustic lining. We usually use fibre glass material for the attenuator baffles, and its thickness and spacing will depend on the noise criteria required for each section of the project. We at SAFID are one of the few manufacturers that have our own fully fledged acoustic lab, which supports our products through testing, research and development of new products or custom-made products for special projects. Our lab was built to performtest in accordance with ISO 7235 and ASTM E477-99, and was accredited by Bruel & Kjaer, coupled with the full R&D Department that oversees new developments and the testing of our products, such as terminal 38

Climate Control Middle East May 2014

At the time of installing ducting systems in a new construction, they are exposed to the elements, such as dust, till the building is completely ready to accommodate them. The usual practice is to wrap the ends up in duct-caps to prevent the dust from coming in. What is your approach to ensure ducts are in pristine condition at the time of installation? With spiral/round ducts, we can actually place plastic end-caps to prevent dust from penetrating into the duct, since the round has standard sizes. In the case of rectangular ducts, however, it’s difficult to do so, owing to the infinite number of sizes. It is a standard practice at SAFID to wrap all air products (dampers, louvres, attenuators, grilles and diffusers, terminal boxes and round fittings) with stretch plastic rolls, while for ducting, this will depend on the contractor and his requirements; sometimes they don’t require wrapped products. If it is a hospital/medical project, in order to maintain hygiene, we apply a stretch plastic, even if the contractor didn’t ask for it.

What insulation materials do you recommend for ducts?

We use two main insulation materials. We recommend fibre glass rolls and boards for the majority of commercial and governmental projects and Rockwool insulation for industrial projects and special applications. We can use other materials – polyurethane boards or foam-injected insulation – based on the requirements of the clients.

What insulation practices do you follow or recommend? And how do you ensure the integrity of the vapour barrier?

We offer internally lined insulated ducts and plenums (fibre glass board with BGT thick-facing) fixed to the internal surfaces of the duct. For externally applied insulation, we offer only double-wall construction, in order to eliminate damage to the insulation and the vapour barrier, where the outer surface can be aluminum, GI, pre-painted galvanised steel or stainless steel for special applications.

interview Dow Coating Materials

Painting a broad picture Dow Coating Materials, a supplier of raw material to the paints industry, covers all segments, including industrial and architectural. In the regional market since the 1970s, the company has eight offices in MENAT.

Excerpts…

has limitations. This feature is important when you consider the fact that formaldehyde is a silent killer. Paint can contribute to insulation coating or solar reflectance. Nowadays, paints are substantially greener. We offer polymers that are zero to low VOCs, and so you can have paints of such nature. Overall, when you look at paints nowadays, you have nice colour, anti-microbial property and low VOC. All these things combined give a full solution.

How has the scope of paints evolved and increased in the buildings industry?

If you think of buildings, there are a lot of elements, including safety, environment, energy efficiency, reduction of energy consumption and cooling. In a building, you have air conditioning units and cooling towers, and whenever you have water, you have calcium deposits and so a need for descaling. Dow also delivers a product that prevents algae and mould. Paint seems simple, but it is not. We have been painting from the time of caves. Paints have evolved – not just in terms of colour but also of functionality. One of the exciting

developments is the formaldehydeabatement feature in paints – a polymer that can scavenge formaldehyde out of the air. This is a novel and niche feature that can help where air conditioning 40

We break down the HVAC system into stages, and we treat each stage alone to maintain the hygiene level of the system When it comes to sickbuilding syndrome, our products can help there. Be it high relative humidity or condensation, paints can offer support as part of total solution in a building.

How do you contribute to reducing outdoor air pollution, which has an impact on IAQ?

To give one example, there are technologies for cleaning the tunnels off microdust, which diesel engines emit.

With the array of features that you mention, it must be

a battle to keep costs down, yes? How would paints of such specialised nature, which translate to higher costs, find a market here? We are talking of a costconscious culture in the region, aren’t we, which means the market would still opt for cheaper paints? We need to unpack the argument that this is costconscious market. While Europe and the US have advanced regulation, paint manufacturers here are committed to the community here and practice selfregulation. Overall, functionality has become title of the game. Paints are becoming a consumer item. The greatest growth in the

coating industry is coming from consumers, because the public expects health, safety, sustainability and performance. Self-regulating companies are selling higher than other companies, because the consumer wants a long-term solution. The market has a need and is willing to pay a premium to meet the need. We are providing full support to our customer. We are making the product from JAFZA in bulk and best-in-class lab with people handpicked for expertise, who develop solutions for market needs. Speaking of which, did you know that two billion dollars is spent on research and development into paints the world over.

What are the drivers for growth for the paints

industry in the GCC?

Overall, two trillion dollars is going to be invested in projects and infrastructure in the region. And one trillion is going to be invested in the industrial sector, so there are opportunities here

Young people that require jobs and houses constitute a driver. There are a number of reports on market need per country. The leading market is the Kingdom of Saudi Arabia. Overall, two trillion dollars is going to be invested in projects and infrastructure in the region. And one trillion is going to be invested in the industrial sector, so there are opportunities here. Consumer awareness on functionality is another major driver. There is greater awareness on health and safety. In addition, Dubai winning the bid to host the 2020 World Expo and Qatar winning the bid to host the 2022 FIFA World Cup are also major drivers.

participation The 2nd Annual Middle East Variable Refrigerant Flow Conference, produced by CPI Industry, publishers of Climate Control Middle East magazine, held on March 31 and April 1, at Yas Island, Abu Dhabi, served as a platform for industry stakeholders to discuss issues surrounding VRF technology and larger concerns about finding cooling approaches that are energy efficient, resource-conserving and economically viable. We bring you the first part of the report.

The 2nd Annual Middle East

Variable Refrigerant Flow Conference 31 March - 1 April 2014 | Yas Island Rotana, Abu Dhabi, UAE

Saeed Alabbar, the moderator for Day 1

nergy security is an issue that encompasses the GCC states. The region relies on fossil fuels for its energy supply. Fossil fuels, however, constitute a finite resource, and with the regional energy demand following an exponentially upward trajectory, the need to conserve electricity and the necessity to find new sources of energy have become more pressing than ever. To encourage energy efficiency and conservation best practices, the governments of the GCC states have introduced regulations and quality assessment programmes. The first plenary discussion on Day 1 of the Variable Refrigerant Flow Conference, (VRF Conference) revolved around the different set of regulations existing in the region, and on how they might help encourage energy efficiency within the technologies on offer and promote environmental stewardship. One of the crucial subjects discussed at this juncture was the advantages and challenges of having a set of regional standards and how the different regulatory and assessment authorities were working towards achieving this end. “When you set up a standard,” said Dr Esam Elsarrag, Director, Gulf Organisation for Research and Development (GORDGSAS), “you have to think of its applicability. We have to set up standards that can be deployed and that is based on the problem.” Elsarrag shared the view that while coming up with standards, his team looks at the situation from several levels. “Can I solve the problem by putting only a systems solution? If systems solution is not enough, we can look at other solutions, like passive design solutions.” May 2014

By looking at passive design solutions, Elsarrag said that the investigation would no longer centre on how one could provide an efficient cooling solution, but on how one could reduce demand for cooling. “If we can reduce the need for cooling, then, at that time, we can use efficient systems. Do we have to increase the cooling requirement then look for a solution, or do we have to limit the requirement for cooling at the beginning?” He said that GORD-GSAS would make an integrated process with the design team to achieve a certain cooling target. “Once we have achieved the cooling target,” he said, “that is the time when we can look at efficient systems. We can apply conventional systems, but we have to exclude the inefficient ones.”

Yes, we are not going to reinvent the wheel, but we are not going to copy and paste blindly Dr Ali Al Alawi, Senior Corporate Environmental and Sustainable Development Advisor, Petroleum Development of Oman (PDO), was of the same opinion, and added, “We need to start our quest to reduce energy from the design stage; then we can do other improvements.” The regulatory and assessment bodies, www.climatecontrolme.com

eventreport however, know that setting up regulations is just the tip of the iceberg, so to speak. One of the main problems that they may face, in light of introducing regulations and conformity assessment programmes, is resistance from the industry at the implementation stage. “To avoid any resistance from industry stakeholders,” said Abdullah Abdelqadir Al Maeeni, Director of Conformity Affairs Department of the Emirates Authority for Standardisation and Metrology (ESMA), “we are involving them in setting up the standards. Our standards and regulations are mainly developed by the stakeholders. They are involved from the first stage of development, so they understand what is required and the reason behind the requirements.” He added that industry stakeholders should know in advance what changes would be required so that they can adjust their designs to comply with the standards. “Since they are involved in the process from the beginning, we (ESMA) do not encounter challenges in terms of implementation,” he elucidated. Abdessalam Benyaich, Conformity Assessment Specialist, GCC Standardisation Organisation (GSO), agreed with Al Maeeni, when he said that he believed there was no single standardisation body that could develop standards on its own. “We have to ensure a framework where everybody can participate. Then, we can ensure a conformity assessment scheme that is most suitable for specific cases. Participation is the keyword here. The industry should be involved, so we can have a suitable set of standards for each objective.” The discussions, then, zeroed in on another important challenge to regulatory and assessment bodies: Keeping up to speed 44

Abdulla Abdelqadir Al Maeeni

In an installation of 100 to 300 TR, in a residential or office building, it makes a lot of sense to install VRF with innovation. In this regard, Benyaich said: “We have to let the technology develop. We should not underpin the development of the technology.” He was of the view that the new way to deal with regulations involved was setting up essential requirements and, then, letting manufacturers submit individual evidence on how they were able to meet the set standards. “In the old way of doing things, we set up standards and we tell the manufacturers to comply with them. It is not the idea now. Again, the keyword here is participation from the industry,” he emphasised. Al Maeeni concurred, and added: “We are asking the manufacturers to develop the technology. We are also working with them through trainings, so that we may also be informed of what technology will come.” After the first plenary discussion, Al Maeeni, Elsarrag and Benyaich took the podium for their individual plenary presentations. As part of our comprehensive coverage of the event, we bring you excerpts from the presentations conducted on Day 1 of the event...

Director of Conformity Affairs Department, Emirates Authority for Standardization and Metrology (ESMA) “Controlling only the ACs is not the right approach to energy efficiency. If we are just controlling one product, then we leave out the other elements in the system. If we only control the ACs, then the lighting systems may be generating heat. We have to strike a balance in terms of energy efficiency. The AC products should meet the minimum of 5.9 EER under the T3 conditions or hot climate conditions. “In 2013, the percentage of two-star systems decreased, while the percentage of three-star products increased. This means that the market is shifting to more energy-efficient products. This is giving us a benchmark for the next update of our regulation. We are looking to stop the one- and twostar ratings, and the present-day three-star rating will be the new one-star, and so on. We will develop two new EER for the four-star and five-star ratings. This will be reviewed every two to three years, in consultation with the industry. “We are looking to cover the full range of cooling systems. This may be issued by the end of the first half of this year (2014). We are now in the process of drafting the regulations with the stakeholders. “We find a challenge: There is no benchmark in terms of energy efficiency and electrical safety for bigger units in the high-ambient temperature countries. There are standards available for the international market, but none of those standards talk about high-ambient temperature countries. We have to make sure that products are complying with energy efficiency and safety requirements under the high ambient temperature conditions.”

Director, Gulf Organisation for Research & Development (GORD-GSAS)

“The main objective of GSO is to help in attaining the objective of integrating the market by ensuring harmonisation of standards and technical regulations. Once we have developed standards, what now? We have to have a suitable conformity assessment scheme or certification scheme, and GSO is dealing with that aspect. We want to ensure that everybody is participating in this process; it is a process where everybody has to agree with [it], then we can enforce it. “At the end of 2013, we have about 10,000 standards. Most of them are voluntary (87%) standards, while the others are mandatory. The number of mandatory standards has shrunk. Before, it was at 20%, because we are now aiming at a new way of introducing standards. We are allowing the manufacturers to employ many solutions to meet the requirements. We are only setting the essential requirements. Then, the manufacturers have the burden to show evidence that their products meet the objective. Then, the manufacturers are responsible for the conformity assessment programmes, providing for possible intervention of [certified] bodies. The manufacturer can draw a technical file and affix the “G” marking. This will give free circulation for products bearing the “G” marking. “For the not-fully-harmonised sectors, like EER, we have started a mutual recognition system. For air conditioners, for example, UAE and Saudi Arabia have two different set of standards. We have set up a system, where regional committee will work in harmonising the standards, say between UAE and Saudi Arabia to come up with one single standard and one single certification scheme on EER. If we can foresee a fully harmonised technical regulation among the six countries, it can be better.”

“We are looking at the overall performance. That is what we want to achieve. If we put elements together, how, as a system, will they perform? Maybe your product as a standalone performs well, but when you put the elements together, the performance may be different. Testing an equipment in the lab is good, but deploying it in a building and how the building will operate is another case. “We have to look at R&D from scratch. People may think that here, in the Arab world, we have to copy and paste. We say ‘sorry, we are not going to copy and paste’. Yes, we are not going to reinvent the wheel, but we are not going to copy and paste blindly. We have to understand our problem, then we will see: If there is something that will benefit me (from what has been done elsewhere), we will take it, but if there isn’t, we will assess and improve it, or we will create a thing of our own. “We need not reinvent the wheel, but we do not want to copy and paste. We need to benefit from what happened worldwide, and we have to build our own according to the GCC context. This way, nobody can criticise the GCC context saying that there is any gap, because we did all the gap analysis. People can bring a very nice statement from a standard in California or from a certain American standard, but it may not work here. You can bring different sustainability standards, but they may not work because our laws are different. Even the laws among GCC countries are different.”

It zeroes in on the methods of smuggling and on the identification and detection of the modus operandi. “We see now that there are more and more combined teams, with customs and police, but it is not always that easy. Owing to its being a subtransnational issue, INTERPOL

is an important body on the police side to bring those entities with each other. “We teach the police officers the basic things on how to recognise counterfeit products. The manual that we have developed is a restricted product, not freely available. If you are from a governmental agency, and you want to have a copy of it, you can always request access to the Environmental Crime site.”

Yonjea Han

Sales Engineer, Samsung “To achieve a sustainable building, these are our suggestions: Using a heat recovery ventilator, one can intake the outdoor cold air to the room (saving approximately 20% of electricity here). At that time, one does not have to operate the air conditioner, so there could be savings in electricity. If we use the geothermal energy for water-cooled VRF, we can use the energy from the ground. In addition, we can use the unit for cooling and heating at the same time. Using efficient lighting can also help in saving energy. Combined with solar panels, we can produce domestic hot water. Normally, the electric heater is used in the Middle East, but the energy efficiency of electric heaters is around 1. But with the solar panels and our water-cooled VRF, the efficiency could go up to more than 5, meaning you can save around 80% of electricity with this. “We can also monitor the energy consumption and the gas or water [consumption] with the power distribution system. We can monitor how much energy is consumed by the gas, by the water or by the electricity."

Sana Hamdani

Strategic Marketing Engineer, Daikin “In terms of energy prospects, the government has a crucial role in setting up regulations. As you know, to reduce the actual energy consumption, the government has been responding with very fast-moving energy efficiency regulations. Just recently, SASO has implemented a minimum efficiency requirement increase of 50% within a time frame of one and a half years. Although the climates in the GCC countries are quite similar and although the challenges are the same, we have different regulations for different countries. Sometimes, even in the same country, the regulations vary per city. The fast-moving regulations, based on high efficiency will completely change the dynamics of the HVAC market. “What will be the impact of the high EER regulations to the HVAC industry? The VRV market will expand towards larger-sized projects, due to its high EER level, and also due to the higher acceptance of the technology. On the other hand, the VRV will also expand to the smaller-sized projects because of the high EER regulation. Here, we will pick up some market from the DX.”

Belinda Fan

Product Management Manager – VRF Systems, Johnson Controls Asia Engineering Centre “Each refrigerant system of JCI VRF products can connect to up to 64 indoor units at the same time, and it can connect to the wired controllers and wireless controllers. One wired controller can connect to up to four indoor units as a group to do the same operation. We can also connect the diagnostic kits to indoor units to do some monitoring or service for any malfunction of the system. It will be very convenient for the service men, because they can remain inside and be able to check the running status of the whole system. “If we connect a BACnet communication board to the outdoor units, we can combine several individual refrigerant systems into a large-scale system. We are the first supplier to enable the BACnet protocol in the VRF system directly."

Imad Kaba

Sales Leader, Trane “VRF makes sense in some capacities, in some loads, and in some applications. I have taken a residential building of 100TR, which is suitable for a VRF system. We also assume that the chiller systems require pumps, so we will be adding the power consumption of the pumps, as well. For this study, I have selected two outdoor units of approximately 52TR. When I select these units, they will give me 1,240 MBH of actual capacity at Dubai conditions and at design conditions. I have also selected a chiller which will give me 1,213 MBH. “What we do is we take the tariff of the UAE which is around 33 fils per kwh. When we apply it to our computations [computation was done in Kaba’s presentation], we get a saving, VRF against screw chiller, of AED 56,000. This is the running cost difference, per year. “In an installation of 100 to 300 TR, in a residential or office building, it makes a lot of sense to install VRF systems. We have lower first cost and lower running cost compared to the chiller system. It is modular and lightweight, easy to install, no pumps and no underground chilled water pipes, and gives us almost the same comfort level.”

Mohammed Mirza Senior Manager for Infrastructure and Vertical Design, Aldar Most of the testing and commissioning people are not qualified, or at the end of the project, there is not enough time for them to do the testing and commissioning. No matter who delays the project, the testing engineer should be able to deliver the project on a particular day. That is when shortcuts are being taken. So, the building may not be commissioned properly…. We should not push the testing and commissioning team to take shortcuts. Maybe, the facility managers should also be part of the testing and commissioning….

Dr Ali Al Alawi Senior Corporate Environmental and S&D Advisor, Petroleum Development, Oman I have been working with solar energy for so many years, and I know that it is not easy to convince people to go for new technology. To convince the people, there is a need to make them understand the benefits of the system, in relation to them and also to the environment. In recent times, people have become more environmentfriendly. It seems that this technology has a very good potential, but there is a need for training for installation and maintenance personnel, and for assurance of good equipment installation.

Kandasamy Anbalagan Managing Partner, Proleed Consultants In any project, we have a testing and commissioning programme that is part of our follow-up action. Most of the time, contractors do not have enough time, owing to a variety of reasons. For chilled water systems, you need about six to eight weeks, and that kind of time is not available. When you walk into some of the buildings here in Dubai, most of the building management systems are not in operation, pumps are running on manual mode, VFDs are not put in place…. The strength of the VRF system, for small to mediumsized buildings, is the observed lesser testing and commissioning time.

FACE VALUE  21 APRIL 2014  RADISSON BLU, DUBAI MEDIA CITY

n April 21, CPI Industry, publishers of Climate Control Middle East magazine and producers of the Annual Middle East Indoor Environmental Quality Conference, hosted a roundtable on paints. Dubbed “Face Value”, the event served as a venue for manufacturers, consultants and government bodies to discuss the role of paints as a component in the broad HVAC strategies contributing towards a better built-environment. The discussions revolved around relevant Dubai Municipality regulations, IEQ-related features of paints (VOC content, antimicrobial features and total solar reflectance values) and the impact of R&D on the manufacturers and on the market. The event benefited from participation of Abdulla Mohammed Al Marzouqi, Head of Certification Unit, Dubai Central Laboratory Department of Dubai Municipality; consulting companies Proleed Consultants, Green Technologies, DC PRO Engineering and Three Factors Company (en3 Solutions) and paint manufacturers, including Berger, Caparol, Hempel, Kansai Paints, Jotun and National Paints.

On VOCs

One of the crucial issues

People need to know that there is no such thing as zero-VOC paints. There will always be VOC content tackled at the roundtable was the observed gap in market knowledge of the products currently available. “Paints with zero VOC content are now available in the market,” said Sarvar Ansari, Technical Manager at Kansai. “VOC certificates are received from Dubai Municipality, and the products are tested by a thirdparty laboratory in order to achieve the certification.” Ahmed El Bayaa, Regional Sales Manager, Caparol, agreed, but sounded a caveat: “There is no differentiation within products in this market. We can certify our products, but a layman may not understand what it actually means.” He therefore stressed the need for identification and clear labeling on the cans. Murtaza Ali Challawal, Decorative Sales Manager, Hempel, highlighted that not all VOCs were actually harmful. “If we speak about VOC content, some are

harmful, while others are not. Say, out of 30g/L, how much of this is harmful?” he asked. Ghaleb Abusaa, CEO, Three Factors Company (en3 Solutions) addressed this point, saying: “The ‘non-harmful’ substances that you are saying are not directly harmful, but they can be indirectly harmful.” He explained that the ‘nonharmful’ substances could react with other compounds. “Since VOCs are either positively or negatively charged, they can react with other substances to produce harmful substances,” he countered. Paranthaman AK, Senior Manager for Regional Marketing, Berger, agreed with Abusaa and suggested that participants put to rest the idea that some VOCs were harmful, while the others were not. El Bayaa, then, made a clarification: “People need to know that there is no such thing as zero-VOC paints. There will always be VOC content.” Hafeez Siddique, Regional Technical Service Manager, Jotun, seconded this and added that the disparity in the interpretation of the amount of VOCs might emerge from the fact that there are several standards used to test paints. “If you test using different standards, the results will be different. Every standard will have its own definition of what VOCs are,” he pointed out. Concluding the discussion on the topic, Marzouqi said: “In fact, Dubai Municipality does not insist on zero-VOC paints. We have several ranges in place, but we can modify the ranges if need be.” Other topics discussed at the event included anti-microbial feature of paints, the viability of nanotechnology, light and heat reflectivity, and the economic impact of new paint technologies (for highlights see relevant boxes).

Then one may see a reduction in the cooling/heating demand. We have to be honest and tell the customers that paint can only affect a building’s cooling/heating load up to a certain level.

Anti-microbial features not just for hospitals RB SINGH, Assistant Technical Manager, National Paints: The anti-microbial features of paints are not only vital for hospitals, but they are also important for a community where health is prioritised. We have to strike a balance, where everything is protected, and where whatever we do will have the least [negative] effect on everybody.have not yet prioritised it.

“We will only pay more, if we are asked to pay more” EL BAYAA: Regulations should be there so we will follow. The change has to be driven by regulations. We have to know [in advance] what is coming next, so that we can be prepared and can adjust accordingly. The reason why there is no impetus on the part of the building owners to patronise sustainable paints is that Dubai is largely a rental market.

CHALLAWAL: In residential buildings, a 4.4% reduction in cooling load may be attributable to paints. Colour may be another issue. [If we want to reduce the cooling load], we may specify white.

SIDDIQUE: High ambient temperature does not degrade the paint. The present technology allows for black paints to also reflect heat. The colour is called ‘cool black’.

RAYAN AWADA, Senior ABUSAA: If you make your customers aware of the consequences of bad paint, they will change their mind.

“The onus is on the manufacturers…” SINGH: In this country, some specifications are outdated. The onus is on the manufacturers to educate the consultants. Some initiatives have to be taken to set up specifications for different applications.

Turkey holds the key

Strategically located at the cusp of East and West, Turkey has always been a witness to history. Now, it is re-asserting itself as an emerging market for a wide array of products and services and as a global gateway. We focus on the rising economic powerhouse.

he gaze once reserved for BRIC countries now seems to have turned to TIMP1 – Turkey, Indonesia, Mexico and the Philippines. Bob Turner, Chief Investment Officer of US-based Turner Investment Partners, who coined the acronym, predicts a new economic world order built on shifting fault lines. Turkey, in particular, has been a beneficiary of the post Gulf War peace dividend. As a report in the Financial Times succinctly summed up, “The Americans won the war, the Iranians won the peace and the Turks won the contracts.”2

Piggy-backing on this, even as countries around the world are trying to recover from the recent financial battering, Turkey has quietly registered a steady growth. According 56

to Turkey’s Sustainable Development Report, “Turkish economy has been one of the fastest growing economies in the world in 2010 and 2011 with 9.2% and 8.5% growth rates, respectively.”3 This is expected to rise, propelled on the one hand by Turkey’s strong middleclass population, making it one of the largest markets for automobiles, consumer, electronics and luxury goods, and on the other, as a burgeoning tourist and export hub. Consequently, multinationals around the world are eyeing Turkey as a bridge country: European companies come to Turkey to enter the Middle East, while Middle Eastern companies consider it an entry point to Europe. Apart from its strategic position, other factors that make Turkey a potential Eldorado are: • A young and qualified labour force – by 2025,

Creating the right environment The need for buildings has increased in Turkey with the increasing population, urbanisation and industrialisation. However, the sector embraces opportunities to minimise the pressure on the environment with design approaches and materials used during construction. In Turkey, 35% of the total sectoral energy consumption belongs to buildings…. The existing buildings will create a field of opportunity in transition to green growth, particularly as regards energy efficiency and usage of renewable energy, besides new buildings to be constructed.4

In Zutshi’s opinion, “The country’s metamorphosis into a service and industrial economy will be complete, with both sectors projected to generate a combined 93% of the country's GDP in 2020.” Reuter added that the change in consumption habits, large investments in infrastructure and aspiration for a better standard of living were guiding the country’s growth trajectory.

appears poised to play an important role on the world stage once again. References: 1 Reuters (US) website: http://www.reuters.com/ article/2013/03/28/ us-column-deaenlle-timpsidUSBRE92R0IF20130328) 2 “Turkey emerges as true Iraq war victor”: Financial Times, Middle East and North Africa, March 12, 2013 3 and 4: Turkey’s Sustainable Development Report: Claiming the Future, Ministry of Development, June 2012, Ankara.

The

compressor market

– a paradigm shift Based on Frost & Sullivan’s research on PD and centrifugal compressors, Virein Kumar Yadlapalli envisages a tilt towards the non-oil and gas segment, which he predicts, will boost the demand for compressors.

T The Middle East and North Africa (MENA) features amongst the fastest growing regions with the oil and gas industry being the key contributor to its development. The local governments’ unified vision towards industrial diversification beyond traditional limits and foray into non-oil and gas sectors has been paying rich dividends. Manufacturing and extended downstream activities have been continuously invested into, to ensure sustenance of the growth path. Economic growth coupled with an increasing population has resulted in significant investment in power and industrial infrastructure. While the region has been largely stable, the recent issues arising out of sectarian divides (and in certain cases 60

Demand for equipment is a natural consequence of industrial growth. Rotating equipment, a critical machinery of any industrial setup, of which compressors is an essential part, continues to witness installations in

Climate Control Middle East May 2014

the region. As per Frost & Sullivan estimates, 2013 revenue for the compressors market in MENA was more than USD 1,700 million, and the same has grown at a healthy rate (more than 7.0 per cent). The market for centrifugal compressors during this period was more than USD 1,173 million while that of Positive Displacement (PD) compressors was in excess of USD 527 million. Overall, the MENA market for compressors is forecast to become more than USD 2,100

million worth by 2017. Frost & Sullivan’s research on PD (including reciprocating and rotary screw compressors) and centrifugal compressors market suggests that a paradigm shift is likely to take place, with the emergence of the non-oil and gas segment as a primary demand driver.

Growing market and intensifying competition

Demand for compressors is dominated by the oil and gas industry in MENA. Given the sophisticated nature of the industry’s requirement, most of the globally renowned compressor manufacturers are present in the region. Major manufacturers specialising in customised solutions, cater to most of the high-value projects (especially oil and gas), and those involving compressors for critical process requirements. As is the case globally, major multi-national corporations, like General Electric (GE), Siemens, Atlas Copco, Elliott Group and Dresser-Rand dominate the MENA market. These companies have engineered portfolios (product/ solution) suited to the local requirements, and their presence in MENA spans across pre-sales and sales support, marketing, and

Industry challenges • Delay and complexity in qualifying as an approved vendor • Adherence to stringent testing/quality requirements • End-users’ reluctance to adopt new technology • Intensifying competition, specifically for standard off-the-shelf compressors comprehensive after-sales support. Also, in more recent times, the otherwise dominant American and European vendors have witnessed high competition from Asian vendors. This trend is attributed to increasing penetration of Asian (mainly Korean) Engineering, Procurement and Construction (EPC)

contractors facilitating greater acceptance of compressors from their respective countries. Of late, there is a surge in investments/plans targeting manufacturing/ assembly operations in the region, capitalising on the advantages (during project tenders) offered to companies with local value-add and conforming to the localisation requirements.

KSA – the biggest market Being one of the biggest markets in the Gulf Co-operation Council (the GCC), the Kingdom of Saudi Arabia (KSA) continues to attract various compressor manufacturers. It even encourages suppliers to set up local manufacturing or assembly facilities in order to tap into this market. Due

COMPRESSORS TURKEY experienced by countries, such as Iran, Iraq, Egypt and Libya, which otherwise offer a huge potential, will be key in determining the progress of these economies. The demand for compressors will be commensurate with the investments being realised. Investments in non-oil and gas sector key drivers In spite of the flagging number of large-scale Greenfield projects (especially in the past five to six years) in the oil and gas industry, demand from this segment is likely to dominate market revenue. Massive investments in the power and water segment are expected to translate into the segment which will emerge as the second biggest source for compressor installations in the next four to five years. Also, the continued expansion (current and envisaged) of petrochemicals, chemicals and fertilisers segments is expected to result in significant demand for compressors. Additionally, there is a huge after-sales opportunity offered by the large installed bases commissioned over decades. Exacting the requirements of compressors, which thereby raise the overall cost through certifications, safety features, instrumentation requirements, diagnostics/monitoring, etc., largely contribute to the revenues.

Aftermarket opportunity spells healthy margins

The replacement market is expected to be a substantial driver for the rotating equipment industry as old equipment undergoes overhaul, retrofits, part replacements or complete substitution with improved technology. This will be a common feature. Escalating energy requirements have resulted in investment in gas-fired plants that need compressors. 62

a growth rate of 7% to 8.5% from 2014 to 2017 is seen for PD and centrifugal compressors Growth in non-oil and gas-based projects, such as petrochemicals, power, desalination, water and wastewater, infrastructure and metals and mining will increase the overall demand for compressors, and moderately reduce the dependence of compressor demand on any specific industry. Also, the non-oil and gas segment presents significant opportunities for the installation of non-American Petroleum Institute- (API) certified compressors. This should particularly benefit compressor manufacturers with a limited range of APIcertified compressors in their product portfolios. It is worthwhile to note that the demand for compressors may witness marginal reduction due to moderation in MENA investments, significant buildup of regional overcapacity, discovery of major oil and gas sources in other countries (major gas finds in the United States, investment in shale gas, deep-sea oil production, and others), as well as the growing impetus world over to develop renewable energy sources. Also, countries in the region are in a state of political uncertainty and unhealthy contagion. Political tensions, global sanctions on Iran, economic imbalance

in Iraq and the effects of the Arab Spring in Bahrain, Jordan and Lebanon, among others, have dampened investor sentiments. Volatility in the global market for oil and gas will have an impact on the compressors market in the short term. The need for a stable source of oil revenue (in the face of depleting/ ageing fields), creating valueadded products (through increased downstream activities), alleviating unemployment and economic disparity and the need for economic diversification will be instrumental in fuelling industrial growth. Hence, investments targeted at extending the downstream activity and continued industrial diversification will be vital for sustaining the regionâ&#x20AC;&#x2122;s growth. The outlook for PD and

centrifugal compressors market is optimistic, with a moderate growth rate of around 7.0-8.5 per cent from 2014 to 2017. Untapped potential for downstream activity in countries, such as the UAE, Kuwait, Qatar and Iraq, provides opportunities for growth. Additionally, new cities, growing population, increasing industrialisation and international mega events will provide the next industrial boom for the compressors market.ď&#x20AC;ź

Straight from

the horse’s mouth

To gain a deeper understanding of compressors and of the several issues surrounding the technology, Climate Control Middle East spoke to industry players Bitzer, Danfoss and CMP. Here are the highlights…. Are you noticing an upturn in the demand for compressors in recent years?

Stefan Leitl, Managing Director of BITZER Middle East

With the special climatic conditions of the Middle East, the region offers a great deal of potential and unique technical challenges for refrigeration compressors, in light of the fact that the need for refrigeration and air conditioning technology in this region is extremely high. Bitzer has observed general organic growth in the markets, which is expected to continue over the next several years. The company has been represented in Dubai with its own sales office since 2003, which is well acquainted with the local conditions. Bitzer has reported a consistently high demand throughout the Middle East. With increasing economic growth, we are extremely

confident that the sales figures for compressors will continue to grow. In addition, the annual Big 5 trade fair held in Dubai also plays a key role.

the demand for compressors or condensing units for air conditioning and refrigeration applications.

What do you think are the drivers for growth of the compressors industry? Bitzer:

We see a bright future ahead of us. As a technology provider, we’re very well prepared for the innovative segment of natural refrigerants with propane, ammonia and CO2, which are becoming more and more important. Moreover, the market development in the Middle East is very promising: The signs continue to indicate an upturn, particularly in Saudi Arabia – the largest market in the region. There’s a lot more potential there.

Biju Kannan Sr. Sales Manager – Key Accounts, Commercial, Compressor & Refrigeration Controls Danfoss FZCO Danfoss has been experiencing a continuous growth in the Middle East for several years now. We have not perceived a slowdown due to the economic crisis, although certain markets have been slowed down due to political factors. The on-going construction projects in the MENA region, approximately valued at USD 4.2 trillion; the growth rate of nine per cent and the similar growth in the cold chain industry lead to a significant increase in

COMPRESSORS TURKEY What new technologies in compressors have you recently introduced to the market? Could you share with us details on them? Craig Taylor, CMP Corporation Technical Specialist

Efficiencies and cost savings are the top drivers of the re-engineered reciprocating compressor market. Our customers are looking to maintain and repair existing equipment, but they want to do so with the latest technology. We have optimised many of our internal compressor parts to take advantage of material improvements, as well as design improvements that make our compressors and parts perform optimally with the new refrigerants and their compatible oils.

Danfoss:

The key drivers come from the general economic outlook associated with the new regulations. The new energy efficiency standards defined in Saudi Arabia for residential air conditioning illustrate the country’s consideration for climaterelated issues. We expect the rest of the region to follow the same trend. The fact that residential units equipped with rotary compressors cannot achieve the new standards leads to a growing demand for small energyefficient scroll compressors, providing less than 6TR of cooling capacity. We expect that these regulations will also push the manufacturers and real estate owners to ask for more energy-efficient air conditioners and refrigeration units in the commercial range. Another key driver is the phase-out of R22 refrigerant, leading to the conversion of air conditioning and refrigeration systems to new refrigerants. 64

Bitzer:

I can name several innovations that we have come up with at Bitzer. The first is that we have further developed our existing CSVH screw compressor series and expanded it to include two larger models. The new CSVH3 range is unique in the segment of speedregulated compact screw compressors, and the CSVH37 facilitates a cooling capacity of 550 kW (+5/50°C) and a displacement of up to 960 m3/h. The CSVH38 is even bigger with a cooling capacity of up to 660 kW (+5/50°C) and a displacement of up to 1,156 m3/h. Another highlight product is the Bitzer Ecoline Varispeed reciprocating compressor. Owing to the integrated suction gas-cooled frequency inverter, the semihermetic compressor can be adjusted in line with the actual cooling demand. The speed range between 25 and 87 Hz increases capacity by up to 70 %, compared to similar compressors with a single speed. The highprecision capacity control reduces fluctuations in suction pressure and cycling rates, improving the efficiency of the

Climate Control Middle East May 2014

entire system. We also have the five models in the Bitzer Orbit 6 scroll compressor series, with a delivery rate of between 20 and 38 m3/h at 50 Hz. The series boasts of high isotropic efficiency levels over a wide range of applications. The units also operate at very low noise levels.

CMP:

We weren’t the first company to introduce PTFE-lined main bushings for reciprocating compressors, but we’ve been instrumental in the proliferation of these types of bushings as replacements across many OEM brands and models. The use of PTFE as a material in main bushings has helped solve problems related to the less-than-optimal lubricity issues of POE oil.

Danfoss:

There are three major areas with products that propose innovative features that we have recently released: n The first area is variable speed technology. In the latter part of 2012, we launched the 2nd generation of Danfoss inverter scrolls, VZH. The VZH range, from 13 to 26 TR, provides the largest cooling capacity with a single hermetic inverter scroll compressor. This year, we will release VZH models of smaller cooling capacities, from 3 to 6 TR. We will also launch a new Danfoss

Turbocor compressor, the VTT. n The second product is the 40 TR Danfoss scroll SH485. The SH485 offers a 40 TR capacity scroll in the shell of a 30 TR compressor. The most important benefit of SH485 is the part-load efficiency over the complete operating map. n In the refrigeration segment, we are now proposing a packaged solution on condensing units designed for harsh climates, the Optyma Slim Pack. These packaged units are designed with scroll compressors and microchannel heat exchangers that render the unit very compact and light, and easy to clean, to install and to maintain. With this new design we aim to get a 35% savings on refrigerant alone.

For which refrigerants are the new compressors designed? What significant developments have compressors undergone in terms of the refrigerants to be used with them? How about natural refrigerants?

Bitzer:

It is important to remember that each refrigerant has its own characteristics: The operating conditions determine whether or not a refrigerant is suitable. Lots of natural refrigerants are either toxic or slightly flammable, or the thermodynamic characteristics are incompatible. Still, natural refrigerants, such as propane, CO2 and ammonia, will continue to become more important in the future. Refrigeration and air conditioning systems are still dominated globally by synthetic HFC refrigerants, and industrial applications by ammonia. Bitzer recognises the increasing role of natural refrigerants years ago and has since introduced them into its portfolio. As such, the company is very well

prepared for the ban on R22 and R123 refrigerants in Saudi Arabia, from the beginning of January 2015. That means that we offer compressors for just about any refrigerant.

CMP

At CMP, we do not design any new compressors, but we have ongoing research and design efforts in valve plate design and lubrication optimisation of current â&#x20AC;&#x153;in the fieldâ&#x20AC;? compressor models. These efforts focus on increasing the life cycles of our component parts and their use with new refrigerants and oils.

Danfoss:

Most of our scroll and reciprocating compressors can run with several refrigerants. In air conditioning, the new compressors in development

are optimised to operate with R410A. We are also developing compressors that can operate with the new refrigerant R32. Samples are already available. In the refrigeration segment, we offer compressors operating with R22, R134A or R404A. The development in the last decade were done with hydrocarbons, R290 and R600A for the small reciprocating hermetic compressor type. In the coming months, we will propose compressors operating with R407A and F that have a lower impact on the environment than the actual R404A. The Turbocor TG series of compressors has been developed to operate with R1234ZE refrigerant.

What effects do new legislation and regulatory guidelines on refrigerants have on compressor design and R&D? Bitzer:

We had already been expecting the latest developments in the refrigerant segment and have actively taken part in the current legislation. At the moment, we donâ&#x20AC;&#x2122;t see any major changes in compressor design. Of course, some refrigerants with a higher pressure will be used or will require special safety regulations because they are flammable. But that will primarily affect the overall system design and the qualifications of the operating and service staff. To ensure the responsible staff is up to date on the latest

information, we have set up training centers round the world.

CMP:

In the US, the phase out of R-22 meant that we had to innovate and upgrade existing internal components, upgrading materials to add longevity, improve oil flow, and introduce components made from polymers that are not affected by the new refrigerants and oils.

Danfoss:

The impact of the new regulation is driving today’s development of compressors. We try to optimise the conversion from the platform, which is the most appropriate for the new refrigerants, like the R410A and R32 platforms. In the compressor industry, the qualification or re-design for new refrigerants is specific to each compressor platform. Specific studies are made to evaluate the volumetric capacity, capacity loss or gain, oil compatibility and motor selection for each refrigerant. The refrigerant selection will impact the operating envelope, the cooling capacity, the efficiency and the discharge temperature, among others.

Let us talk about compressor reliability: What reliability issues do you usually encounter among your customers? How are you able to resolve them? Bitzer:

Our compressors are designed to withstand improper operation, provided the oil supply is maintained, the system is clean and the temperature limits are observed. Most cases of compressor breakdown are the result of improper use and not manufacturing defects, which is why a part of our services comprises familiarising customers with the compressor. We regularly offer productspecific customer seminars, say on reciprocating compressors, 66

screw compressors and CO2, at our international training centers.

CMP:

Our research has shown two main factors that reduce reliability of a re-manufactured compressor. First and foremost is the improper clean-up of a system that has had a compressor failure, and not determining and correcting the root cause of the initial failure. Second is the use of improperly reclaimed or inferior internal component parts. A proper root cause analysis should determine not just how the compressor failed, but also the reason behind the failure. There are many factors external of the compressor that directly affects its lifespan and reliability. The second half of the reliability issue is addressed by CMP on our re-engineered compressors by using only minimal reclaimed components, and by designing and manufacturing our internal parts so that they are better able to last in the conditions required by modern systems.

Danfoss:

In very hot climates, the high discharge temperature is key to reliability in the region. Our scrolls don’t experience issues with reliability, as our scroll compressors have the highest maximum ambient temperature in the market that can reach up to 68°C for R410A. With Turbocor centrifugal compressor technology, it is very important to ensure that the application is chosen with regards to the compressor operating limits – particularly at part-load operation. This is why we strongly recommend only water-cooled applications in the Middle East region. With our Danfoss drive, some basic recommendation in the selection of the drive will ensure safe operations in the high-ambient temperatures.

Huayi Compressor Barcelona, manufacturers of compressors under the brand Cubigel, shared information on their latest product offering said to be in response to the market’s growing demand for sustainable technologies. Here are the highlights….

ur product offer consists of five ranges, covering from 2.4 to 34 cc, suitable for several voltages and working with all types of refrigerants and applications. Sustainability is always a key consideration, and major efforts have been directed towards the design of more environmentally friendly compressors. Our Green Cooling range was launched in 2010 and is touted as the most efficient range of compressors working with natural refrigerants, like propane. Future developments go in the same direction as the market is asking for sustainable solutions. The Green Cooling range by Cubigel Compressors allows efficiency improvements while reducing the energy consumption of the application by up to 45% to 55% compared to the standard versions. The Green Cooling range also includes variable speed compressors that offer maximum efficiency by electronically self-adjusting the compressors’ speed to the required cooling needs, while improving COP by up to 50%.

Are reliability issues tied to incorrect and inadequate installation processes? How are you addressing this front? Bitzer:

We very often determine that the systems have been incorrectly operated. Common causes of errors are incorrect system control or improper maintenance, for instance. Systems are also often incorrectly adjusted for new system requirements. This is why we provide training courses. In addition, using the global maintenance and service network, Green Point, we offer the same quality standards for repairs and error analyses all over the world. We also invest in training centres and academies at locations around the world, including in Rottenburg-Ergenzingen and China. We, then, immediately apply the experiences gained through these training courses to new developments and improvements in Bitzer compressors.

CMP:

For the installation of a replacement compressor, proper cleanup is paramount.

Education and training is key. Technicians are the key element to assure a proper compressor life span. We have educational materials available that cover these topics.

Danfoss:

Most of the reliability issues are associated with application and installation of compressors. In a recent study we did in China, we have found that more than 70% of compressor failures are directly linked to application failure. The situation is similar in the Middle East. We offer daily technical support to our customers. Besides, failure due to installation issue can be addressed by increasing the level of awareness and skills among the ranks of the technicians. This issue is much more challenging in refrigeration, where the selection and installation of the units are localised and done by local contractors. We conduct training courses to address this topic. We have direct, face-to-face training sessions; online training sessions and e-lessons to educate the market. We have a free online training platform, called Danfoss Learning, to support the various training needs of the industry.

'Natural refrigerants make economic sense'

eurammonâ&#x20AC;&#x2122;s experts Janos Winter, Refrigeration Consultant at QPlan, and Bernd Kaltenbrunner, Managing Director at KWN Engineering and member of the eurammon Board, explain how natural refrigerants can be put to energy- and cost-efficient use.

W Whether in food production or in the manufacturing of chemicals or medical drugs, refrigeration and air conditioning are essential parts of the production process and subsequent storage. In light of this, natural refrigerants offer the most environmentally friendly option for refrigeration applications, as they have no impact on the greenhouse effect. But the potential of natural refrigerants goes beyond just the ecological advantages. They also offer economic advantages. You have drawn up a payback calculation that shows both the economical and ecological advantages of using natural refrigerants. How did you go about calculating this? Janos Winter: Basically, there is one main thing that has to be taken into account: when calculating the payback period of an investment, it is important to consider all the costs incurred throughout the entire lifecycle. The 68

total operating costs include the initial outlay and all subsequent costs for the plant, together with the costs for repairs, energy, maintenance and service. It is in this area in particular that plants operating with natural refrigerants are so convincing. Thanks to the lower operating costs, the initial outlay for these refrigeration systems can be recouped after just a few years. So, the payback period for a system is calculated

Climate Control Middle East May 2014

The increased safety requirements for systems with natural refrigerants mean that particular care must be taken in all aspects of operating safety according to the entire lifecycle. Are systems with natural refrigerants also particularly economical in terms of their service life? Janos Winter: We cannot really generalise here. The service life can vary in each individual case. The lifecycle of a system depends on various aspects, such as the technical concept and the specific application or external factors, such as climatic conditions. High

outside temperatures, for example, require a greater refrigerating capacity. And so, each application has to be viewed individually and compared with suitable alternatives. But in most cases, it is usually easy to find alternative applications with natural refrigerants that offer a long lifecycle, which, therefore, also makes them more economical. It is difficult to compare various systems using differing refrigerants. Nevertheless, are there any reference values or key figures that give an indication of how energyefficient a system is? Janos Winter: Definitely. For example, when we compare the annual energy consumption of refrigeration systems, we use software-based computation programs, such as â&#x20AC;&#x153;Pack Calculationâ&#x20AC;?, which was developed by the Danish IPU Institute. It takes account of most aspects of technical implementation as well as the climatic conditions. One thing transpires here again and again: ecological and economic advantages often make natural refrigerants the best choice for nearly every application. Which requirements have to be taken into consideration when planning a system with natural refrigerants? Bernd Kaltenbrunner: Basically, the same planning requirements apply as for synthetic refrigerants. But the increased safety requirements for systems with natural refrigerants mean that particular care must be taken in all aspects of operating safety. In addition, it is also important to give due consideration during the planning phase due to the fact that, as a general rule, systems with natural refrigerants have

a long service life of up to 25 years and more. Ammonia is a refrigerant with outstanding thermodynamic properties that is deemed to be particularly efficient. Do systems with ammonia offer the greatest potential for saving costs and energy? Bernd Kaltenbrunner: Ammonia systems, in particular are convincing in terms of their long service life. Accordingly, the planning procedure for these systems gives especially careful consideration to the sustainable selection of individual components in the interests of longterm energy and cost efficiency. This already gives ammonia systems a clear advantage over other systems in terms of potential savings. But in every profitability analysis, the

As a general rule, systems with natural refrigerants have a long service life of up to 25 years and more operator also has to decide which approach he wants to take for his system. Experience shows that environmental aspects, in particular, play an increasingly important role in this process. And ammonia

offers clear advantages with regard to environmental concerns. This gives us two powerful arguments that explain why ammonia systems have already become an established force in the refrigeration industry. In which branches do natural refrigerants make particular economic sense? Bernd Kaltenbrunner: Natural refrigerants are recommended for companies in every branch of industry that set store not only by the environment, but also by business indicators. The key point here is that ecological awareness and economic efficiency are mutually compatible when natural refrigerants are used. What role do operating costs play in refrigeration systems? Is this another area where systems with

www.climatecontrolme.com

naturalrefrigerants special sUppleMeNT natural refrigerants can rate highly? Janos Winter: Systems with natural refrigerants generate considerable savings, particularly when it comes to the lifecycle costs. Increasing annual operating hours make energy costs a crucial factor. A direct comparison shows that this is an area where natural refrigerants really stand out, as they permit more energy-efficient refrigerating machines. But energy efficiency depends on more than just the choice of refrigerant: It is also affected by external environmental factors, the specific design of a system or the level of training that the operators have had. There are many successful examples to illustrate the efficient use of natural refrigerants. Could you name a project that

Janos Winter: The retail sector is clearly the pioneer here, particularly in supermarket refrigeration, with systems

Climate Control Middle East May 2014

using natural refrigerants. In Scandinavia, for example, we have seen particularly highefficiency rates in systems with natural refrigerants in this sector, resulting, among other factors, also from the advanced state of knowledge among planners and clients. In Hungary, too, there are clear demonstrations of the energy advantages of natural refrigerants in supermarkets. NH3/CO2 cascade systems, in particular, generate annual energy savings of up to 35% compared to similar HFC systems. To foster the development of “green refrigeration”, some countries offer subsidies for systems with natural refrigerants, while others even put a tax on refrigerants with a detrimental effect on the environment. What is the situation in Germany?

Bernd kaltenbrunner: Through the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU), the German government offers a subsidy for climate protection measures in industrial refrigeration systems. If the subsidy criteria are fulfilled, a maximum of €200,000 of the net investment costs are refunded. Needless to say, refrigeration systems with natural refrigerants are also subsidised, as they rate above all other options when it comes to efficiency; and furthermore, they cause no harm to the environment. The extremely low global warming potential – ammonia, for example, has a GWP value of 0 – also naturally plays a major role in obtaining subsidies from the BMU.

Fresh for the future – natural refrigerants in the food industry Pointing out that the continuing increase in energy costs and a greater awareness of environmental issues will bring about a further increase in the trend towards natural refrigerants, three eurammon members explain how they have put them to successful use in the food industry.

T The natural refrigerant, ammonia has proven its worth in industrial refrigeration for nearly 130 years. After a boom in the use of the now-prohibited CFC refrigerants during the 1960s and 1970s, ammonia is today being put to increased use in industrial refrigeration. The main reasons concern the efficiency and low environmental impact of ammonia. It is one of the most efficient refrigerants of all, offering convincing performance in terms of economic efficiency and environmental friendliness , as it has no direct ozone depleting potential (ODP = 0) and does not contribute to the greenhouse effect (GWP = 0). The continuing increase in energy costs and a greater awareness of environmental 72

Combining refrigeration and waste heat exploitation

The refrigeration plant is combined with a heat pump in a particularly energy-efficient concept, so that the company can make full use of the waste heat generated in the system issues will bring about a further increase in the trend for natural refrigerants. Three eurammon members explain how and where they put natural refrigerants to successful, cost-efficient and future-oriented use in the food industry.

Climate Control Middle East May 2014

Kellermann.ch AG produces and sells fresh vegetables and vegetable convenience products, including quickly perishable goods, such as chopped and packed salads for the convenience sector. An extension to the company’s logistics complex

resulted in great additional demand for refrigeration. At the same time, for most of the year, the company needs heat for its greenhouses. To offer the most costefficient, environmentally friendly solution to satisfy the demand for both heat and refrigeration, eurammon members SSP Kälteplaner and Johnson Controls Refrigeration planned and installed a central refrigeration supply system for the warehouses with a heat pump to heat the greenhouses. The two-circuit refrigeration system with two 550 kW low-pressure refrigeration compressors cover the required refrigerating capacity of around 1,000 kW. The engineers deliberately opted for reciprocating compressors, which stand out compared to screw compressors on account of their far lower operating costs under the given operating conditions. They cool the water/glycol blend in the refrigeration consumer circuit down to approximately -8°C for direct refrigeration of the warehouses. The refrigeration plant is combined with a heat pump in a particularly energyefficient concept, so that the company can make full use

of the waste heat generated in the system. The combined heat/refrigeration plant covers Kellermann.ch AG’s additional refrigeration demand in a sustainable, cost-optimised way with significant reductions in heating costs. There are environment benefits as well: The integral concept reduces the burden on the atmosphere by around 1,000 tonnes of CO2 each year. It was this environmentally sound business approach, among other reasons, that prompted the Swiss Climate Foundation to support the project.

New biscuits, new refrigeration

With the new system, the company was able to close down an existing system that ran on the refrigerant R22, thus credibly underlining its sustainable environmental policy

Verkade (United Biscuits) in Zaandam is about 18°C. The temperature must never exceed a maximum of 22°C, as otherwise, the product quality would suffer. Increased production and the introduction of a new type of biscuit brought the existing refrigeration system permanently to its capacity limits, so that additional refrigeration capacity had to be hired at great expense in order to maintain the required temperatures. Naturally, this problem became particularly acute during the summer months. In its search for a suitable new refrigeration machine with a rated capacity of about 1,000 kW, the company decided in favour of a liquid chilling unit from GEA Grasso, which works with the

May 2014

natural refrigerant ammonia. However, the building which housed the old machine scarcely offered sufficient space for a new refrigeration system. This was another key factor in favour of the highly compact system, which could be installed without any problems, thanks to its small floor area of just 5 x 1 metres and a height of 2.1 metres. The refrigeration machine itself offers convincing performance with a particularly high energy efficiency ratio (EER) of 5.0 under full load, with the EER even increasing to about 10 under 25% partial load. This results, among other reasons, from the frequency converter integrated in the system for demand-related control of the screw compressor speed (European seasonal energy efficiency ratio ESEER 8.0).

The solution brought multiple benefits for Verkade. With the new system, the company was able to close down an existing system that ran on the refrigerant R22, thus credibly underlining its sustainable environmental policy. The investment also made economic sense. Among other benefits, the company now saves the great expense of hiring additional refrigeration capacity, as the new system efficiently keeps biscuits and chocolates at the required temperature even during summer.

Huge warehouse buildings and extreme temperatures The family-run company CDS Hackner GmbH in Crailsheim near Nuremberg produces and refines natural casings for sausage skins and is one of Europe’s market leaders in the processing of animal by-products, including beef and lamb. The company also offers its customers a wide range of deep-freeze services, including storage, freezing and controlled defrosting. In response to the constant increase in demand, CDS Hackner GmbH decided to expand its refrigeration and storage capacities, investing about €13 million

The storage capacity was increased from 15,100 to 26,000 pallet spaces. In order to refrigerate two new deep-freeze warehouses, each with about 20,000 m³ at a ceiling height of 12 metres, eurammon member Johnson Controls installed a new energy-efficient refrigeration system with an ammonia filling of approximately 2,000 kilogrammes. Two speed-regulated Sabroe screw compressors cover the necessary refrigeration capacity of 760 kW. An economiser is integrated in the screw compressor to maximise overall system efficiency. Frequency converters optimise the output of the drive motors for highly efficient operation in the partial load range. In total, two deep-freeze warehouses are supplied

Climate Control Middle East May 2014

by the new refrigeration system. Three shock-froster rooms were connected to the existing CO2 refrigeration plant. An industrial NH3 brine liquid chiller supplies refrigeration energy for the natural casing warehouse and various processing rooms. The system is based on two frequency-controlled piston compressors with ammonia separator and plate evaporator. The cooling system with its entirely new concept gives CDS Hackner the ideal technical, hygienic and economic conditions to expand its production capacities and continue its successful international expansion.

A clear trend towards natural refrigerants

The use of natural refrigerants in the food industry increasingly makes both economic and ecological sense. More and more companies advocate NH3-based refrigeration concepts in new systems or when expanding existing capacities, for both economic and ecological reasons. The slightly higher initial investment is offset by distinctly lower operating costs, so that systems operating with natural refrigerants have the potential for being more cost efficient in the long run. The increased awareness of environmental issues among the general public, in industry and in the political sector is another important incentive for using natural refrigerants. For example, more and more companies are drawing up their own internal sustainability guidelines and actively communicate this environmental commitment to the outside world. In this context, they can make a relevant, credible statement by changing from CFC to natural refrigerants, which neither deplete the ozone layer nor contribute to the greenhouse effect.

City of L端bbecke uses environmentally friendly cooling

Propane gaining ground Propane is a tried and tested refrigerant and is increasingly in demand, says eurammon. It supports its arguments with case studies.

A At the end of June, the Environment Committee of the European Parliament recommended a faster and stricter reduction of F-gases (fluorinated greenhouse gases) than expected, by operators. This more than ever brings into focus natural refrigerants, such as the hydrocarbon propane. Despite 76

specific safety standards, propane applications are easy to implement and are increasingly popular with planners and engineers, who consciously seek new refrigeration systems and a sustainable solution in terms of environmental protection and energy efficiency. Propane does not contribute to the greenhouse effect and has a very low global warming potential. Another advantage is the short payback period due to low energy consumption and operating costs. The following case studies from eurammon members show the areas where propane is particularly suitable.

Climate Control Middle East May 2014

Propane does not contribute to the greenhouse effect and has a very low global warming potential

The Stadtwerke L端bbecke (public utilities) turned to Wilhelm Schriefer with the desire for a new refrigeration plant which provided both air conditioning to the building and reliable cooling to the server room. The plant engineers were to find an environmentally friendly solution with a cooling unit whose refrigerant ideally did not increase ozone depletion or global warming. After a thorough examination, the choice fell on a brine chiller unit with the natural refrigerant propane. The chemical properties of the hydrocarbon were considered in the project planning. Based on the estimated refrigerant charging amount of 2.5 kilogrammes, a concept was created to deal with safety measures. This included the outdoor installation of the system on the roof of the L端bbecke municipal administrative building. A high level of preassembly facilitated the setup of the compact housing, which covered, in addition to the water chiller, all other components, water supply connections, safety system and the controller. Apart from the basic components, such as condensers and evaporators, the plant engineers opted for the special R290 version of a semi-hermetic reciprocating compressor from HKT Huber K辰lte-Technik. Pressure controllers (for low and high pressure, respectively) and a safety high pressure limiter were also used in the system. A vacuum heat exchanger increased the efficiency of the system, since an increased enthalpy difference for the same amount of refrigerant could absorb more heat energy. The cost savings resulting from this helped pay back the purchase price of the heat exchanger within a year.

Besides the ecological advantages of the system, the overall cost benefits were impressive. “Regardless of all political debates, the stated arguments explicitly speak for this comprehensively sustainable technology. It is particularly noteworthy that the low operating costs compensate for initial extra costs in less than three years,” says Karl Huber, the Managing Director of HKT HuberKältetechnik-GmbH.

German supermarket chain opts for integral cooling and heating systems

The innovative, compact unit supplied to a renowned German supermarket chain was to meet the latest environmental standards and at the same time be cost efficient. The goal was to develop a prefabricated unit which provided for the generation of the required cooling for refrigeration units and cold storage rooms, air conditioning of the sales area and the heat supply of a floor heating, including the electrical equipment for the entire supermarket. Futron provided the concept and developed the new unit together with thermofin. “Convincing arguments for the use of propane as refrigerant included the high energy-efficiency ratio, the low pressure level and pressurised gas end temperature, as well as the relatively low price,” explains Willy Löffler, a senior official at thermofin. The compact unit comprised both the refrigeration system with 130 kW cooling capacity for cooling and a heat pump with 40 kW heating capacity. The refrigeration units and cold storage rooms were cooled indirectly with propylene glycol as secondary refrigerant. The need for low temperature was supplemented by an additional cooling unit as a CO2 cascade system. An additional evaporator circuit in the lamellar blocks of the air-cooled condenser brought the heat from the ambient air to the floor heating. The low energy consumption of the system and the positive effect in terms of environmental protection were quite impressive. The characteristics of propane reduced the CO2 equivalent of the refrigerant from 9.07 to nearly zero. “The prototype of the integral system has even surpassed the expectations of our customers,” says Willy Löffler. “There are now more than 200 systems in operation, which demonstrates that propane is absolutely qualified for mass production today.”

Cascade system cools hops in the Hallertau region As one of the world’s largest hop traders with its own production, Hopsteiner based in Mainburg (Hallertau) relies on natural cooling. Their old R404a refrigeration system was to be replaced by a larger cold brine system with 130 kW. To process the sticky hop cones mechanically, it needed temperatures as low as -35˚C. Based on this, Robert Baust of Robert Schiessl presented a cascade system with CO2 and propane. The decisive factor was the future-

proof, environmentally friendly overall package solution with low operating costs. Moreover, the investment costs balanced out in a short time, thanks to the statutory subsidies. Since 2009, the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) has been funding the renovation of old refrigeration plants and the construction of new systems by up to 25% of the costs, provided all the prescribed guidelines, such as the use of natural refrigerants, the compliance with a specific TEWI value or a fixed

annual power consumption are observed. To avoid dangerous situations in the event of propane leakage, it was also necessary to take special safety precautions while designing the complex propane/CO2 cascade system, in addition to accommodating the specific characteristics of the refrigerant. Six Bitzer semi-hermetic reciprocating compressors were installed in total, which were designed for propane and subcritical CO2 applications. The planner also decided to use new microchannel technology from Güntner – a desuperheater for R744, a condenser and a subcooler for R290. These components were made of aluminium and belonged to a new series, which was specially approved for inflammable refrigerants like propane. The

key argument was, however, the extremely low refrigerant charge, thanks to this technology. Despite the subcoolers, a charge of only 44 kilogrammes was needed for the R290 section of the refrigeration plant. Due to all these special components, the system proved to be very efficient and kept the operating costs low. Additional energy benefits were created by speedcontrolled compressors with frequency converters and electronic injection valves. The operator was delighted to report remarkable COP values, which were as high as 2.3 at a brine temperature of -38˚C. “Hopsteiner is so satisfied with the concept that the company has already ordered a second cold brine system with 100kW, of course, with

propane,” says Robert Baust of Schiessl.

Other application areas for propane

These practical examples demonstrate that propane systems are environmentally friendly and energy efficient. It is already feasible to make individual customised systems as well as standard series production models. Today, propane is already established in medium and small capacities up to 100 kW (as in heat pumps or air conditioners in the food retail sector), as well as in logistic cooling with refrigerating capacities of up to 300 kW. The high efficiency of propane applications is a decisive argument to persuade engineers and operators to go for the environmentally friendly alternative.

COunTIng EnErgY And EnVIrOnMEnTAl COSTS Identifying consistent air quality, improved performance, reduction in energy consumption and environmental benefits as the prerequisites of air filtration systems, Prasad Natraj predicts that they will govern the future of the air filtration industry in the region.

ecent trends in the manufacture and optimising of air filtration systems lie in four clear objectives: consistent air quality, improved performance of the installed air filtration system, reduction in energy consumption and environmental benefits. Air filtration is no longer a necessity only for equipment protection but also for the health and well-being of building occupants. Most people perceive the need for air filters only as a means to protect the cooling/ heating coils and equipment downstream, which is patently untrue. Air quality is a key factor in the comfort and health of the building occupant, optimising production processes and reducing the environmental impact.

The importance of clean air

Clean air is something practically impossible to identify by our human senses. Most airborne particulates are so small that they cannot be perceived with the naked eye. In most cases, we do not know when

something is wrong with the air quality until it is too late, and when irrecoverable damage has already occurred. A carefully selected and reliable functioning air filtration system directly determines how effectively harmful contaminants and particulate matter are prevented from entering the air stream, and thus represents a vital link in the overall improvement of Indoor Air Quality (IAQ).

While on an average, fans in the Air Handling Units utilise 40% of the total energy requirements of a building, the air filters used in those systems consume 25% of their energy demand. No less than 80% of the total costs within the lifecycle of an air filter are energy costs. Low-energy filters, therefore, immediately reduce environmental impact and lower the total cost of ownership. Further, in today’s scenario, reducing energy demand of buildings is not only smart because of governmental regulations but also due to rising energy costs. With the new guidelines, energy labelling on each category of air filters is already in operation in European countries. The 2014 energy labels on the air filters vary from “E” for low energy efficiency up to and including “A” for extremely high energy efficiency. With this method, Eurovent can validate the claims of manufacturers concerning annual energy consumption of filters. This gives

customers a guarantee that the product delivers as per the energy classification.

Green initiatives

Today’s building owners and operators are moving towards sustainable designs and operating practices of increasing efficiency of buildings. The benefits of such sustainable or green buildings include the valueadded perception of social responsibility, enhanced IAQ and lower operating costs. An increasing number of commercial buildings are seeking LEED certification. Proper air filtration strategies can earn LEED credits via Energy and Atmospheric Efficiency, Indoor Environmental Quality, Materials and Resources and Innovation in Design/operations. The

higher the efficiency of a filter, the better the IAQ. Filters with lower pressure drop and higher efficiency will lower the operation cost of HVAC systems, resulting in energy savings, which ensure lower energy costs and reduced greenhouse gas emissions. Lastly, but equally significantly, the potential environmental impact of raw materials used to make filters, and the impact on the environment during the disposing of the filters at the end of service needs to be considered.

IAQ – the Middle East situation

Unfortunately, there appears to be minimal consideration among buyers locally in terms of installing higher efficiency filters which contribute to lower energy

consumption, improve IAQ and support green initiatives. The buying patterns are predominantly based on washable-type air filters, which tend to lose arrestance values over repeated washes and increase pressure drops across the media. Without local certification and a clear directive in place, customers end up paying higher energy costs in operating their HVAC systems and, most significantly, sacrifice on achieving proper IAQ for the building occupants. With the local presence of recognised global air filter manufacturers these days, and with the ongoing market awareness, the healthcare industry is typically complying with the use of higher efficiency air filters for operation theatre

rooms and areas serving critical care. The healthcare industry is very keen to support quality-driven air filter products and the use of sustainable technologies to conserve energy.

Scientific data indicate that an adult male with a sedentary activity will breathe about 15 m3 (15 kilogrammes) of air, drink 1.5 litres (1.5 Kg) of water and eat 0.75

Salah Nezar, Corporate Sustainability Director at Qatar Project Management, which manages numerous projects in the region, has considerable experience in the field of IEQ. Here, he shares his views on cost effectiveness of improving indoor environment, supported by global case studies.

his article represents a segment of a scripted journey in the world of sustainability, taking me to different continents and countries with the aim of collecting hard data for quantification of human productivity gain from improved Indoor Environment Quality (IEQ). This effort was also a good opportunity to meet the leading worldwide researchers and scholars in the field of thermal comfort and Indoor Air Quality (IAQ), including the famous Ole Fanger, global pioneer in defining the contours of human thermal comfort zones in the early 1970s by developing models of predicting acceptance levels. In the world of real estate development, stockholders routinely consider primarily

initial cost and expected operation and maintenance costs when it comes to making investment decisions for as-usual buildings. For sustainable built environment, green advocates often face the obstacle of justifying the premium cost when the benefits from the conscious design are strictly contained within the box of environmental stewardship. The approach should attempt a path that goes above and beyond the classic routing by accounting for the financial benefits gained from improved human performance over the building lifecycle cost. Furthermore, most people today intuitively believe that factors like improved fresh air ventilation rates, daylight harvesting, enhanced ergonomics will, in fact, be

more productive for work environment. Yet, it has been always difficult, due to unavailability of data, to boil it down to the hard numbers. The first steps in simplifying the equation of quantifying human productivity gain is the consideration of the people surrounding environment and the careful examination of the peopleâ&#x20AC;&#x2122;s activity. People in the GCC region spend almost 95% of their time indoors, comprising 70% at home, 20% at work or other premises (for nonworking class) and five per cent in vehicles. As the levels of ventilation and air filtration at home are generally very modest due to the current design practices of delivery of fresh air to the space, the significant amount of time spent at home has

The regional spectrum

Deteriorated indoor environment and Sick Buildings Syndrome are the driving forces behind the prevalence of asthma in the region. Presently, asthma represents the most common chronic disease

perspective during childhood in the GCC region. In a recent study conducted by Hamad Medical Corporation in Qatar among school children aged between six and 14 years, reveals the prevalence of asthma by 19.8%, allergic rhinitis by 30.5% and chest infection by 11.9%. The study showed that the frequency of the three symptoms among parents is following the same pattern as seen in their children. In another study conducted by the UNC Gillings School of Global Public Health in the UAE, researchers collected data from numerous homes for five air pollutants types – sulphur dioxide, nitrogen dioxide, hydrogen sulphide, formaldehyde and carbon monoxide – and monitored IAQ for one week. The results indicate that 30% of audited homes had measurable levels of sulphur dioxide and 29% had quantifiable levels of formaldehyde. For nitrogen dioxide and hydrogen sulphide, nine per cent and 12% of households, respectively, recorded measurable concentrations. Family members in homes with measurable sulphur dioxide, nitrogen dioxide and hydrogen sulphide were twice as likely to have doctor-diagnosed asthma. The research team also found an increased prevalence of wheezing, including symptoms that limited speech, in relation to these same pollutants. Neurological difficulties, such as difficulty concentrating, were loosely linked to quantifiable exposure of formaldehyde. The current situation in the region has also a bright side, as Dubai Municipality confirmed in 2013 that it will carry out IAQ tests in public buildings. This is a highly encouraging initiative across the region.

INDOOR AIR QUALITY

Globally speaking Salah Nezar summarises seven illustrative examples representing research findings published in the course of the last 20 years exploring the relationship between IAQ, health and human productivity....

Study 1:

In a survey of 100 US office buildings, 23% of office workers experienced frequent symptoms of Sick Building Syndrome, such as respiratory ailments, allergies and asthma. The impact usually saw lower productivity and higher medical costs, with enormous economic impact – an estimated decrease in productivity around two per cent nationwide, resulting in an annual cost to the United States of approximately $60 billion.

Study 2

Dr William Fisk, Scientist and Head of the Indoor Environment Department at Lawrence Berkeley National Laboratory in California, was one of the early researchers to examine IAQ’s effects on health and productivity. He established a baseline for quantifying benefits from improved IAQ and demonstrated the economic impacts of increased productivity. Findings showed that improvement in IAQ can reduce SBS symptoms by 20 to 50%, reduce asthma by eight to 25%, reduce other respiratory illnesses by 23 to 76%, and improve office worker productivity by 0.5 to five per cent.

Study 3:

A recent study by Dr Bjarne Olsen, Chairperson for the International Center for

Climate Control Middle East May 2014

Indoor Environment and Energy (ICIEE) in Denmark, indicated that improved thermal comfort, reduction in indoor pollutants, and enhanced ventilation rates can increase productivity by five to 10%. Conversely, the research also indicated that a 10% decrease in tenant satisfaction with IAQ results in a one per cent drop in productivity.

Study 4:

Dr Pawel Wargocki VP & Scientist at ICIEE has published a number of papers related to the effects of IAQ on human performance representing the syntheses of three separately conducted studies under two different paths, demonstrating clearly an increase of productivity estimated to be five per cent or more through IAQ improvements. The first path recommended altering IAQ by removing pollutant sources with constant ventilation rates of 20 CFM/ person. The second path focused on changing the amount of fresh air (6, 20 to 60 CFM per person) with the presence of an identical pollutant source.

Study 5:

Prof Olli Seppanen, from the Helsinki University of Technology conducted a study demonstrating that cost analysis of any officebased business will indicate that staff remuneration

represents the major part of total business operating cost and the economic gain as a result of a minor improvement in human productivity can easily lead to a pay back of the increased cost associated with an improved ventilation and thermal comfort levels. The study revealed that even a one per cent increase in work performance can be the equivalent to the annual cost of ventilating an office building. Staff productivity gains of just 10% can lead to the equivalent of the total installation and running costs of the ventilation system in an office building. And that payback time for investments to improve the quality of the indoor environment is often less than two years. Furthermore, conclusions were derived from the quantitative relationships between IEQ, health and human performance. Higher ventilation rates reduced the prevalence of infectious diseases. For example, increasing the ventilation rate from 0.5 to 2 Air Changes per hour (ACH) can

The study revealed that even a one per cent increase in work performance can be the equivalent to the annual cost of ventilating an office building

reduce illness and sick leave prevalence by up to 10%. The same study said that increasing ventilation rates from 6.5 up to 17 l/s per person can improve office task performance by 1.5%, and that every reduction in the percentage of people dissatisfied with the perceived air quality can increase the work performance by one per cent. The study also said that optimal productivity is achieved when the indoor temperature is maintained between 20°C and 24°C. If the temperature is higher than 24°C, a 1°C decrease can increase work performance by about 15%. If the room temperature is lower than 20°C, an increase of 1°C can increase work performance by two per cent.

Increases in ventilation rates 10l/s per person, up to approximately 20l/s per person, are associated with a significant decrease in the prevalence of sick building symptoms, or with improvements in perceived air quality. A 10% decrease in the prevalence of typical symptoms, such as headaches can increase productivity by 1.5%.

Study 6:

Dr Shin-Ichi Tanabe from Waseda University in Japan published his findings on effects of thermal comfort on task performance and fatigue. The study was related to office spaces with moderately high temperatures. In Japan, it is recommended by law that office building thermostats be set at 28°C in the summertime. The

study showed that human productivity dropped by 2.1% when the average indoor air temperature increased by 1°C. Hot environments require more cerebral blood flow to maintain the same level of productivity at 25°C. Mental fatigue increases when cerebral blood flow increases. This study also found that individual air velocity control was able to reduce the perception of mental fatigue by the workers.

Study 7:

In a study conducted by Dr Allan Hedge, Director of Human Factors and Ergonomics Laboratory at Cornell University, the effect of low temperatures in workspaces was said to have a negative impact on productivity gain.

The study looked at the productivity of nine stations within an insurance company office in Orlando, Florida. The study was conducted over a timeframe of 16 days, during which the workers were assessed in moderately low temperature spaces below 22.2°C coupled with moderately low humidity spaces below 40% R.H. His findings show that “chilly workers not only make more errors, but cooler space temperature could increase the hourly labour cost by 10%.” An increase in space temperature from 20°C to 25°C will result in savings of USD 2 per worker in productivity, decreases the hourly cost by 10%, reduces typing errors by 44% and increases typing output by 150%.

IAQ â&#x20AC;&#x201C; filtering out impediments Like other areas of filtration technology, understanding air filters and their correct application is a complex realm. Appropriate air filter selection helps users avoid some of the costly mistakes that lie in ambush for the uninitiated in techniques of filtration. Dr Iyad Al-Attar, air filtration expert, walks us through the process in this Q&A.

P Professional filtration and maintenance practices will prove invaluable for those engaged in HVAC and GT fields, industrial hygiene, air pollution control, or environmental sciences, as they need to have, both a practical understanding of their profession and its ethical implications in relation to the evaluation or control of airborne pollutants. Here are a few pointers.

What is the connection between increasing air pollution and filtration? We live in an evidence-based

Climate Control Middle East May 2014

Filtration practices lack innovation, as the entire improved indoor air is envisaged as a luxury world, and global warming scores higher records every year. Air pollution is a worldwide problem, as emission from several industrial activities is on the rise. Once an emission occurs, no matter what its physical and chemical characterisations are, filtration

seems the sole defensive mechanism to preserve clean air. An increasing number and type of pollutants signifies more stages of filtration, which requires more energy to drive the air through them. But air filters can also have their own limitations, ranging from dealing with high dust concentration to toxic particles. It is important to realise that air filtration can have its limitations when it comes to solving all of our air pollution problems.

Literally, anyone can assemble air filters and package them for sale without conducting any sort of testing

Air Quality is connected to our urban one. Secondly, it requires improvement. And thirdly, that we are willing to do something about it.

Where does that lead us? Leaving behind a planet that is cleaner and healthier than the one we inherited is a challenge. If we continue to take the problem of pollution in the Middle East lightly, it is inevitable that we will pay the price for being in denial and undermining the science of exhaust air filtration. Being confronted with frequent sandstorms, as also extreme climatic conditions in terms of temperature and humidity, necessitates the need for policy making and changing the paradigm to empower people and governments to implement the required corrective action. We can neither lose the thrust in our quest for clean air, nor the momentum to utilise filtration technology to obtain it. Therefore, we ought to confront the truth that clean air requires protection.

Why is the issue of air filter quality usually below the radar?

Pollen grain strained by filter media

What can we do to ease the pressure on the environment?

Before we start advising our children, letâ&#x20AC;&#x2122;s start with ourselves, by turning off the lights when we are not in the room and limiting the use of air conditioning, knowing that most of our power generation goes to air conditioning in the GCC region. Further, we need to try to make sure that we unplug and turn off all of our appliances when weâ&#x20AC;&#x2122;re not using them. All of these

Dr Iyad Al-Attar

practices would ease some of the pressure on energy usage, and in turn, on the environment.

What do we need to change first, our beliefs or practices towards air filtration?

We need to start by changing the prevailing belief that air filtration is an unimportant accessory in any HVAC system. Filtration practices lack innovation, as the entire improved indoor air is envisaged as a luxury and the filtration segment in the HVAC system is regarded as a mere appendage. Yet, we all demand our indoor air to be free of particles and contaminants, gaseous or otherwise. But do our actions step up to the plate to serve the overall objective? The answer is no. Frankly, if our approach to air filtration had changed as fast as our adaption to the social media, for example, then Indoor Air Quality would have ranked as the top priority by now. The real first step begins when we acknowledge that our Indoor

May 2014

The issue of air filter quality revolves around parameters that we do not see with the naked eye. Why have decades of research, centuries of development, years of scientific investigation and analytical minds to innovate have gone into it? Is it to eventually use the conventional practices and washing disposable filters to save costs, not lives? The quality aspect of filtration hinges on where we lay our emphasis and priorities. Air filtration is also connected to emission and our environmental behaviour. Therefore, world leaders need to take a stand to protect economies to pass a law to protect the air we breathe. Clean air and water are also always connected to our emission problems. If we reduce emission, then our spending on air cleaning equipment can be lowered. New and tougher emission standards for tomorrowâ&#x20AC;&#x2122;s vehicles are required now more than ever. I always wonder, if no one is willing to adapt to changes and recent innovations in filtration, then there is no need to conduct research and development, and no need to grant scholarships to

on research and experimental endeavours that require great deal of time and money. The change of mindset will not only be a turning point in filtration, but a game changer. If price is the only criterion, then filtration conferences are merely overseas excursions.

study and acquire degrees in filtration engineering. Perhaps, names such F. Albrecht, A. Kaufman, Nikolai Albertovich Fuchs, A. A.Kirsch, I. B. Stechkina, C. N. Davies and R.C.Brown and many others will only be at the back of our minds as the founders and contributors of the science of air filtration.

Where do we stand as far as clean air is concerned?

Well, the practice of selecting and installing air filter in our region is deregulated. Literally, anyone can assemble air filters and package them for sale without conducting any sort of testing. This is alarming, as the entire filtration process is microscopic and requires intensive testing to verify the air filter performance claims made by each manufacturer. Also, the climatic conditions in the GCC region add another aspect of complexity to filter assessment, which underscores the importance of testing in conditions that are close in nature to that in the GCC region. This requires a regional testing standard â&#x20AC;&#x201C; to be proposed and implemented â&#x20AC;&#x201C; in order to regulate filter

The onus also rests on consultants to look into the details in an integrated manner to consider air filtration as an inseparable part of the AHU and the entire HVAC system manufacturing to meet the regional requirements. The onus also rests on the consultants to look into the details in an integrated manner to consider air filtration as an inseparable part of the AHU and the entire HVAC system.

How much do market trends affect our air filtration selection? The toughest trend that affects our approach while purchasing air filters is the price-driven market. This overshadows the entire message of the need to provide textbook

Climate Control Middle East March May 2014 2014

filtration. For example, if we consider filters from different manufacturers, they appear to look the same in terms of specs. But do we question media properties, how they operate in the AHU and whether or not they can sustain the required operational flow rates? And most important, can they really do what their manufacturers claim they do? Once again, the role of testing needs to be highlighted here. The government involvement is imperative in being the single body to approve filter performance and give the green signal only to those manufacturers who meet with approval parameters to sell their products in the market.

What is the role of R&D in the scenario of a price-driven market? Letâ&#x20AC;&#x2122;s put it this way: If we allow a price-driven market to flourish, then there is no need for an R&D department in filtration manufacturing facilities. If people are only looking for the cheapest and, therefore, conventional products, then there is no need to expend our energies

First of all, we need to change our approach to the science of air filtration that many of us regard as just a practice. There is still a lot to be desired from air filter manufacturers to provide the most appropriate filters selection for specific applications, as well as in the area of quality control, in order to present the final product to the GCC market. We must also consider characterisation of our indoor air. There are many handheld units that can help in making such measurements, which would prove invaluable in assessing the Indoor Air Quality and correlating it to the urban air quality.

Do you think responsibilities are allocated appropriately and fairly in the matter of filtration?

Prior to addressing the issue of allocating responsibilities for providing and protecting clean air, it is important to admit that we have an increasing problem of pollution. To allocate responsibilities fairly, we have to agree that every one should have access to clean air. Our approach seems to lack precision and fairness, as the essential homework of investigating the GCC dust and its physical and the chemical characterisations has simply been overlooked. This is of great importance from the point of view of filtration, environmental hygiene, medicine

Spotlight

and toxicology. The investigations undertaken must be representative of the regional loading conditions of the filters.

Why is good IEQ critical for the region?

If we were to consider respiratory disease statistics, we would immediately realise that there must be a correlation between frequent sandstorms and the number of hospital admission due to lung problems. Another parameter that can contribute to the filter performance deviation is the high dust concentrations due to sandstorms in our region, which may not match the concentration specified by the international standards. If the filter segment in our HVAC systems fails to protect us from the pollutants we are being exposed to, operational concerns emerge regarding air filter selection. Further, no one can afford to overlook the importance of atmospheric dust characterisation in

recognising the challenge of dust loading of filters.

Apart from sandstorms, which are the other culprits?

Depending on what the atmospheric air carries in terms of introducing additional pollutants, it can come from parking areas, vehicle emissions, ambient traffic and construction activities. All these contaminants challenge the air filters installed in the buildingâ&#x20AC;&#x2122;s HVAC system. And their excessive concentrations alter the dynamic performance of the filters. Sandstorms assault our indoor spaces and add to the complexity of the filter performance deviation problem. They bring higher concentration of suspended atmospheric particles that affects nearly all human and industrial activities. Had appropriate filter selection been made and proper maintenance measures exercised throughout the year

If price is the only criterion, then filtration conferences are merely overseas excursions to the required professional degree, air filters would have played an important role in protecting human beings and industrial applications from pollutants suspended in the air stream.

As a speaker at the IEQ conference this month, what do you hope to hear and see in terms of concrete action? I believe we ought to lead a change if we ever want to ever meet our filtration goals. We can claim that clean air is one of our top priorities. But it is going to require a thoughtful approach that

accounts for the possibility that air filtration can, indeed, fulfill the expectations it is meant to. Climate change and sandstorms burden our air filters with pollutants, which once again, highlights the fact that if we are really willing to achieve the objective of better IEQ, it would require a strong environmental policy, effective steps towards emission reduction and professional air filtration to deal with pollutants that succeed in invading our indoor space. Frankly speaking, people will want to see decision-makers take on these issues in an aggressive way.ď&#x20AC;ź NOTE: Unless otherwise referenced, the images used in this article are copyright of the author.
