FOCUS

34 Unleashing VPF technology

Saying that operational efficiency and profits are directly tied to process chiller performance, Imran Ali of Argonaut gives a glimpse of specially designed chillers for different process cooling applications.

Centralised air conditioners should ideally provide comfort and energy efficiency. Variable Primary Flow systems coupled with Pressure Independent Balancing and Control Valves deliver on both counts, says Ismail Serhan Ozten of Danfoss.

espite Ukraine, despite Iraq, there seems to be a stubborn optimism in the air when it comes to discussing the economic fortunes of the region. However, though it may be true that we are in the midst of a nascent economic upturn, which has engendered this optimism, there are several underlying factors that will determine the extent to which we can capitalise on the mood and bring about significant change.

Contributing Editors Pratibha Umashankar prati@cpi-industry.com Anoop K Menon anoop@cpi-industry.com

Engineers find themselves facing a unique opportunity – a second chance, so to speak – to breathe best practices into the projects they suddenly find forthcoming. Consultants, who speak of their order books never being so full since the Great Recession, have a chance to wring out the frustrations of the past few years – in a telling fashion; and so do other stakeholders.

Senior Business Development Consultant Stephanie McGuinness stephanie@cpi-industry.com Design Genesis Salao | getty@cpi-industry.com

The mind goes back to the frenzied mid-noughties, when buildings were springing up seemingly overnight and which required the full complement of HVAC services – in an instant. More times than not, the client wanted quick solutions, which in retrospect, required more than manic late nights spent poring over yellow-bathed drawing boards. The chickens came home to roost even before Lehman happened, though. Today, consultants, pointing out to buildings, candidly speak of IEQ and energy efficiencies gone wrong. Horribly wrong, in some instances.

Webmaster Troy Maagma troy.maagma@cpimediagroup.com Database/ Subscriptions Manager Purwanti Srirejeki purwanti@cpi-industry.com

Against that backdrop, the questions to ask ought to be: Are we truly prepared for the nascent upturn? Have we bulked up on adequate resources – to name one critical and basic need – to soak up the pressure of unreasonable deadlines, so that we don’t jettison fundamental engineering approaches, leave alone best practices? Have we the courage, conscience and the balance to ensure structures that help people, the society and the region’s economy progress through better IEQ and resource conservation?

The destination of thermal comfort, moisture control, noise and vibration reduction, power savings and GHG emissions reductions require more than cookie-cutter approaches. They need the right investment of thoughtfulness and the luxury of time to take a step back so as to anticipate and prevent the oft-seen sad scenario of two steps forward and four steps backward.

To state the obvious, the revival of construction activity is welcome and great for the economy. No doubt, the cranes will soon enough fly in and settle down. It’s a tough proposition to strike a balance in the midst of all the buzz and thrill, but the right mindset will yield rich dividends.

In another communiqué, Empower shared the news that Ahmad Bin Shafar, CEO of Empower, received the Unsung Hero Award at the event. He was reportedly recognised for his contributions in transforming Empower from a startup to the world’s largest District Cooling services provider over the last decade. Bin Shafar was instrumental in one of the largest acquisitions

in the international District Cooling industry recently, as the company acquired Palm District Cooling in January, the communiqué added. The company’s portfolio now stands at an estimated one million Refrigeration Tonnes of cooling capacity, which is the largest of any single company in this sector, Empower claimed. Ahmad Bin Shafar, CEO of Empower, speaking about the company winning the awards, said: “This milestone reflects Empower’s successful strategy to maintain the perception of real estate developers regarding high standards of District Cooling services. District Cooling services have become environmentally and economically optimal solutions to be used in residential and commercial buildings, hotels and offices due to their significant

efficiency in operational costs, maintenance and preservation of energy and environment protection.” In the wake of the international recognition, Empower reiterated that Dubai hosting the next IDEA conference, bringing together 600 experts in December, would prove to be the ideal platform to showcase the district energy industry’s achievements. Tabreed announced the news of it winning a Silver award each, in the “Total building area committed outside of North America” and the “Number of buildings connected to District Cooling outside of North America” (during the same year), category. On the occasion, Jasim Husain Thabet, Tabreed’s CEO, said: “We are

Will provide cooling to present and additional projects

abreed has announced that it has signed a new agreement with the UAE University (UAEU) to provide it with 17,500 tonnes of cooling for the institution's existing and future projects. Tabreed said that it began providing cooling to the UAEU main campus in 2009, and that the new agreement paves the way for the university to make further connections to Tabreed’s dedicated plant, once its future projects are completed. The projects under construction by the UAEU reportedly include storage facilities and student

accommodation, which are expected to be connected to Tabreed’s District Cooling plant at the end of the year. Commenting on the agreement, Jasim Husain Thabet, Tabreed’s CEO, said: “We are proud to provide critical infrastructure support to the leading educational institution in the country. We have been partnering with the UAE University for more than five years, and this

Dubai Chamber achieves LEED Platinum

First existing green building in Arab world to achieve the accolade

he Dubai Chamber of Commerce and Industry has announced receiving LEED Platinum – the highest possible rating. Calling it another first in the Arab world, the announcement highlighted that the Chamber had also achieved the basic level LEED as the first existing building in the region in 2009. Giving further details, the Chamber said that earlier, it was certified LEED pre-renovation to demonstrate that existing buildings could be greened without major investments, and that soon after its renovation, which was necessary to upgrade the building’s systems and fittings after 15 years of operation, it achieved LEED platinum, the highest level of the US Green Building Council’s globally recognised standard. The Chamber claimed that it succeeded in reducing energy and potable water consumption per person by 63% and 92%

This long-term collaboration is a clear endorsement of the energy, environmental and economic benefits of Tabreed’s District Cooling services.”

respectively, accumulating an estimated USD 5.8 million of savings between 1998 and 2013. While the majority of these gains, said the Chamber, came from simple low-cost initiatives, such as turning off the air conditioning and lighting after hours, a number of innovative practices with attractive payback periods were also applied, which included using recycled water for landscaping and washroom flushing, using the outdoor fountain as a heat exchanger to cool the server room, and capturing condensate for the fountain and washroom systems. Such initiatives, the Chamber pointed out, led it to receive an energy star rating of 91%, implying that it is more energy efficient than 91% of comparable buildings in the United States. HE Hamad Buamim, President and CEO, Dubai Chamber, pointing out that this global honour came after many years of hard work, said, “This achievement reaffirms the Chamber’s commitment towards sustainability and being a role model for the business community.” He also underscored that this was in line with the strategic vision of the Dubai Government, which emphasises the adoption of sustainable practices through green buildings and other measures.

KEY INSIGHTS ON WHAT'S MAKING NEWS

Sweetening the partnership Michele Bedin, Managing Director of Euroklimat, the Italy-based chiller manufacturer, speaks to Climate Control Middle East about the recently signed partnership agreement between his company and Andrews Sykes Climate Rental. Here are the highlights….

When was the partnership agreement signed? Could you give us a background of events that led to the partnership? The partnership agreement in Dubai was signed in January 2014. In finalising the agreement, we took into consideration the long history of our relationship with Andrews Sykes in Europe since 1999. We have been able to provide around 500 chillers for the Andrews Sykes Group in Europe. These chillers were employed in various uses, such as comfort cooling, data centre cooling, process cooling and refrigeration. Our long-term relationship with them has led to this partnership.

Are you opening a new office here in the Middle East? We have opened our office in January 2014 in Sharjah, UAE, which has ample space for keeping our chillers and spare parts. The management of Andrews Sykes Climate Rental heads the office and our sales and service team is handling our operations.

mechanical, chemical, pharmaceutical and oil & gas industries. We have the capability to serve this market. Our latest project involved the installation of chillers in Abu Dhabi ice rink, and our next three chillers are going to be installed for the biggest ice rink in Doha, Qatar. We see ourselves well established in this region very soon.

In light of this partnership, will you be offering new products or services to the region? Is there any region-specific product that you will only offer to the Middle East or will all the services be the same across all regions? We will offer the Middle East similar products and services like we do in Italy. However, keeping in mind the Middle East weather conditions, we have designed a new range of chillers, which work smoothly in high temperatures. These chillers with screw compressors and R134A gas have the capability of easily providing cooling even when temperatures soar up to 55° C. We also have the capability to design custom chillers based on client requirements. STOCK IMAGE ONLY

What kind of partnership will this be? We were looking forward to present Euroklimat’s products and services in the Middle East, since our company has been active in the Italian chillers market since 1963. For this purpose, we decided to start operations in Dubai with a strong sales and service team. This isn’t a joint venture, and no new company will be formed. Khansaheb Sykes, which has a successful history in the UAE for renting out de-watering pumps, have agreed to provide us with the logistics support. Andrews Sykes Climate Rental, a sub-division of Khansaheb Sykes, would be distributing and promoting our products in the Middle East.

What market challenges is your company hoping to respond to with partnering with Andrews Sykes? Our biggest challenge was being able to distribute our units in the Middle East and having a consistently improving sales and service team. With our partnership with Andrews Sykes Climate Rental, we have been able to tackle both the above challenges effortlessly.

Do you, then, consider the Middle East as an important market for your business? What do you think are the drivers for growth for your business in the region? Middle East is one of the most important markets that we are looking at, not only because of the climate conditions but also because this region is growing a lot in terms of infrastructure, real estate and logistics. Seeing the development pace of the Middle East region, there are diverse industries investing and advancing their business here. We believe that we will be able to introduce our chillers for process applications in plastic moulding, food,

DOE updating national reference standard for commercial buildings

Belimo ZIP Economizer recognised Chosen as Money-Saving product by Buildings magazine

Standard 90.1-2013 could become frame of reference

elimo has announced that Buildings magazine has selected its ZIP Economizer as a 2014 Money-Saving Product winner, as part of a group of 97 products showcased in the magazine’s June 2014 issue. The finalists were reportedly evaluated by the magazine’s editorial staff for the money-saving qualities they offered to building owners and facility managers in areas, such as energy consumption, water savings, lighting, envelope improvement and maintenance.

preliminary analysis from the US Department of Energy (DoE) shows that the ASHRAE/IES’s 2013 energy efficiency standard contains energy savings over the 2010 standard of 8.5% source energy and 7.6 site energy. Revealing this in an official communiqué, ASHRAE dubbed it the first step by the DOE in issuing a ruling that could establish the 2013 standard as the commercial building reference standard for state building energy codes. Giving details, ASHRAE said that in an announcement in the May 13 edition of “The Federal Register,” DoE had attributed greater energy savings to improvements in ANSI/ ASHRAE/IES Standard 90.1-2013, Energy Standard for Buildings Except Low-Rise Residential Buildings, related to better lighting, fans, commercial refrigeration, boilers and controls. ASHRAE said that DoE was presently receiving comments on the preliminary determination, and that more information could be found at http://www.energycodes. gov/regulations/determinations. In light of this, ASHRAE informed that if the preliminary determination was finalised, then the states would be required to update their codes to meet or exceed the 2013 standard. Currently, they must reportedly meet or exceed the 2010 standard, which served as the commercial building reference standard for state building energy codes under the federal Energy Conservation and Production Act.

Trend Control Systems Energy Manager

laiming that it is a powerful tool for highlighting and investigating energy waste within a building, Trend Control Systems has announced developing Trend Energy Manager – a webbased energy management package for users of BEMS. The manufacturer lists the following product features and benefits: n Trend Energy Manager enables energy and facilities managers to monitor gas and electricity consumed by their building services and its effect on their organisation’s carbon footprint. n Based on Trend’s iMAT M&T software, it can provide automatic reporting of incidences

of energy overuse and can even be configured to suggest probable causes. n As it can be scaled to suit the size of application, it is viable for small single buildings as well as large campuses. n As a web-based package, it can be accessed by authorised users from any location. n It comes on a CD with its own installation program and requires no knowledge of programming or databases to set up. n Once connected, it will browse the BEMS and produce a list of system meters/sensors from which the data collection points can be selected. The maximum number of data points will usually depend on which one of four standard versions of the

VortiJet series of injectors

ighlighting that all Vortisand (vertical design) and H2F Vortisand (horizontal design) models are now equipped with patent- pending VortiJet injectors, Sonitec-Vortisand has introduced the VortiJet series of injectors for Vortisand cross-flow microsand filtration systems. The manufacturer lists the following product features and benefits: n VortiJet injectors allow for an energetic sweeping action while preventing media bed disturbance which occurs with other cross-flow filtration designs. n This results in better filtration capacities and increases filtration runs by five to 10%. n It also leads to more efficient backwash, resulting in less water required during the backwash cycle, as it can capture the dirty backwash water at a 360 degree angle. n It is located at the top section of the vessel, which allows for a plug flow design which increases the efficiency at which the dirty backwash water is evacuated from the Vortisand. This results in water savings between 20 and 50% compared to the traditional injector design.

software – 50, 100, 250 or 500pts – has been purchased from the VAR. n Readings from meters that are not connected to the BEMS can be imported into the Energy Manager in CSV file format or entered manually. It is also

possible to import historic data recorded on a ‘963’ supervisor. n It is available through Trend’s network of VARs or can be hosted on an end-user’s behalf by the company’s Energy Support and Solutions Team.

NEW VORTIJETTM INJECTORS All Classic Vortisand® (vertical design) and H2F Vortisand® (horizontal design) models are now equipped with exclusive, highly efficient patent pending VortiJetTM injectors that allow for an energetic sweeping action while preventing media bed disturbance which occurs with other cross-flow filtration designs.

INTRODUCING THE NEW VORTIJETTM SERIES OF INJECTORS FOR VORTISAND® CROSS-FLOW MICROSAND FILTRATION SYSTEMS

BETTER FILTRATION CAPACITIES

With the former single injector system, only a single area of cross-flow filtration is created, and inevitably only a portion of the filter is thoroughly active in the filtration process. On high solid loading situations, this may cause a hydraulic imbalance which could result in the formation of preferential channels in the media, or “channeling”. The VortiJetTM injectors, by optimizing the Vortisand® sweeping action, greatly minimize the risk of this phenomenon without compromise. Furthermore, the unique and patent pending VortiJetTM injector will typically increase the filtration run by 5 to 10%. OLD INJECTOR

THE PROCESS COOLING REPORT

Cooling applications using self-contained process chillers Saying that operational efficiency and profits are directly tied to process chiller performance, Imran Ali gives a glimpse of specially designed chillers for different process cooling applications.

Introduction

There is a need for end-users to understand the concept of higher cost process chillers as against lower cost HVAC chillers

Factors to be considered

• When downtime is more critical than breakdown of an AC system • When required chilled water parameters cannot be compromised, ie, flow, pressure and temperature • Round the clock operations 26

Climate Control Middle East July 2014

within a wide range of ambient conditions are needed, ie, 15°C to 50°C • Onboard tanks, pumps and controls should also play a vital role • When anomalies in parameters and fluid quality cannot be compromised • Integrated supervisory controls ie, remote monitoring/control, auto changeover, system bypass etc

Since traditional HVAC chillers are not designed for rigorous process duty, loss of production even for a short period is usually much higher than the equipment cost difference.

Applications of process cooling

Process cooling can be divided into three major segments: • Light industrial applications • Heavy industrial applications • Commercial and institutional applications The following are the areas of application: Light industrial applications • Bakeries – dough mixing cooling • Dry cleaning – cooling of dry cleaning machines • Printing – cooling of heated printing rollers due to friction • Potable water cooling • Machine/oil cooling in small-scale industries

STOCK IMAGE ONLY

Process cooling chillers, unlike cooling for comfort (air conditioning), provide cooling or extract heat mainly from a fluid required for a process to maintain a particular temperature during a process. It could also be used to cool equipment or its components. Process cooling chillers are often compared to their equivalent tonnage of standard HVAC-type chillers within different applications. Therefore, there is a need for end-users to understand the concept of higher cost process chillers as against lower cost HVAC chillers. The cooling processes vary from one HVAC application to another. A significant fact to be noted here is that operational efficiency and production profits are directly tied to process chiller performance and reliability. Consequently, there are basic design differences.

• Multiple circuits and technologies for large turndown ratio

Heavy industrial applications • Emergency safety showers and eyewash facilities • Concrete batching plants • Plastic industries • Die-casting plants • Food & beverage industry • Sewage water treatment plants • Reverse osmosis plants • Machine/oil cooling (several applications) • Quenching applications Commercial and institutional applications: • Medical applications (X-ray, MRI, CT Scan, etc) • Laboratories • Drinking water systems • Swimming pools • Cold plunge pools

Practical process cooling – a concrete batching plant There is a demand for temperature-controlled concrete for large construction projects around the world. The strength of the concrete is accompanied by the evolution of heat. The phenomenon of curing and hardening of cement (heat of hydration) is not of much importance in small structures, but very significant in a mass concrete process. This is because, here, the heat of hydration raises the temperature during the

Figure 1

curing process by up to 25°C, causing an increase of volume. After the concrete is cured, it cools down again, reducing its volume, thus causing cracks. The initial pouring temperature, therefore, should be lowered to such a degree that the maximum temperature during the curing process does not exceed a certain degree determined by the consultants. Even though the required pouring temperature of the concrete varies from site to site and from country to country (from 4°C to 15°C), there is always a requirement for a sophisticated chilled water system.

Overview of the layout for process cooling chillers

Process cooling chillers can be assembled on: • Single skid, uniform enclosure • Single or dual skids – integrated on field, not fully enclosed • Multiple skids integrated and piping inter-connected on field (multiple single or duplex chillers may be provided) The above can be understood from typical illustrative schematics in Figure 1 and Figure 2. July 2014

Is environmental quality a Catch-22? The threat of being exposed to pollutants and harmful environmental elements is always present, be it outdoors or indoors. Stay outside and risk inhaling dust, sand and particulate matters. Remain inside and be vulnerable to VOCs, harsh odours and re-circulated airborne viruses. What, then, can be done? The first panel discussion at the 2nd Annual Middle East Indoor Environmental Quality Conference in Dubai revolved around these issues. Here is our report.

nyone who has lived in the Middle East through the summer months will tell you that it may not be a bad idea to run for cover and stay indoors during sandstorms and when the mercury rises to 50Â°C. During this season, for instance, an average person is observed to spend more than 90% of the time indoors, be it inside the office, his car or his home. In doing so, he may be keeping himself safe from external forces, but, as discussions and presentations at the 2nd Annual Middle East Indoor Environmental Quality Conference, produced by CPI Industry, publishers of Climate Control

Climate Control Middle East July 2014

Middle East magazine, revealed, he may be subjecting himself to harmful elements that he may not know of. Dr Yousuf Noman, Co-Chair of the Healthy Building Interest Group at the Qatar Green Building Council warned that exposure to pollutants was 25% greater indoors than outdoors. In relation to this, Noman shared the fact that the World Health Organization (WHO) estimated that 20% of the worldâ&#x20AC;&#x2122;s population is exposed to indoor air pollutants 100% greater than the recommended level. Owing to indoor air pollution, he said, nearly 2,000,000 people die every year.

THE 2 NDANNUAL MIDDLE EAST INDOOR ENVIRONMENTAL QUALITY CONFERENCE 12-13 May 2014 | Hall 5 & Al Multaqua Ballroom, Dubai International Convention and Exhibition Centre (Dubai World Trade Centre), UAE

Salah Nezar, Corporate Sustainability Director at Qatar Project Management added that exposure to indoor air pollution was not the only downside of staying indoors. “Another problem,” he said, “is thermal shock.” With outdoor temperatures in the Middle East reaching as high as 50°C, Nezar said that immediately entering a room with a significantly lower temperature might present a grave danger, particularly to children and the elderly. This, he said, could increase the probability of respiratory illnesses, which could also result in cardiac complications. The situation, however, is not at all Catch-22 – where no one is safe no matter where he one stays. Dr Ahmad Al Shatti, Consultant, Occupational & Environmental Medicine and Director of OHD at the Ministry of Health, Kuwait said that in order to address the manifold contexts of the issue at hand, there must be a synergy among different stakeholders, including the government, the healthcare industry and the engineering fraternity. “We have to come forward and create a venue where we can discuss these issues,” he said, adding that the stakeholders must bear in mind that the issue represented more than plain statistical data. “Workers are not numbers, they are people. The government and the companies have to realise that every dollar they spend on promoting health will yield more profit than invested elsewhere.” Dr Ahmad Al Shatti, Consultant, Occupational & Environmental Medicine and Director of OHD at the Ministry of Health, Kuwait said that in order to address the manifold contexts of the issue at hand, there must be

The government and the companies have to realise that every dollar they spend on promoting health will yield more profit than invested elsewhere.” H.E. Abdullah Rafia, Assistant Director-General of the Engineering and Planning Sector at Dubai Municipality agreed with Al Shatti and added that in order for the synergy to be possible, awareness programmes needed to be extensive. “Awareness in this part of the world is more difficult," Rafia said. "Awareness programmes can be expensive, but we cannot do without them.” He cited the example of how his office worked to promote the Green Building Regulation in Dubai. “For the Green Building Regulation, we have launched an extensive programme for all levels, including consultants, contractors, suppliers and manufacturers,” he revealed. Rafia also shared his opinion that green and sustainable practices should not stop after the construction of facilities. “We should continue [the best practices] through the operation and maintenance," he said. "This is where our programme’s benefits have to been seen – from the beginning of a building, through occupancy and maintenance.” Noman agreed with the two preceding speakers, and said that in Qatar, sustainability is promoted as a responsibility July 2014

of all sectors of society. To cap off the discussion, Al Shatti shared his view that health should be at the centre of all sustainable development initiatives. He urged all those present, particularly the engineers, the hygiene experts and the doctors, to work together and tackle the issue of health and safety and environmental quality from a multidisciplinary perspective. “We have to remember,” said Al Shatti, “that the human beings are the most precious elements in the world.” www.climatecontrolme.com

TECHNOLOGY

It is to state the obvious that most commercial buildings have very low occupancy after office hours or during weekends. This renders operating centralised air conditioning systems during these times wasteful. The challenge is to run them efficiently. In example 1 the building has 10 floors and all of them are occupied from morning till late afternoon. During evening time, a single floor is open for business. Thus, the centralised air conditioning system that distributes air for the entire building has to work for the sake of cooling only a single floor. Modern building outlook requirements do not allow an additional air conditioning equipment to be displayed outside the building. Therefore, running a separate smaller air conditioning system is not an option. In such a scenario, the Variable Primary Flow system could be the answer. 34

Variable Primary Flow system: Introduction

Variable Primary Flow (VPF) system was commonly published in the 1990s and is superior to Primary Secondary Flow system in terms of energy efficiency. In the growing interest of energy efficiency, some engineers have now come to think that the VPF system may be employed to work better at very low load condition. In general, this system has lower initial and operation costs compared to primary secondary flow system. The following are the saved initial costs: 1) Elimination of secondary pumps 2) No swing chiller needed 3) Fewer pipe connections 4) Fewer electrical connections 5) Less floor space required 6) Smaller bypass size Saved operation costs are: 1) Varying primary pump speed 2) Varying compressor speed/ quantity in compressors/ quantity of chillers 3) Efficient chiller performance even during part load Despite the merits stated above, the system has its limitations which are highly reliant on the hydronic balancing and control performance.

load 8) Manual balancing valves/ flow limiters or automatic balancing valves Note: Flow limiters, also known as Automatic Balancing Valves, are not recommended to combine with item #1 modulating control valves, because their characters oppose one another, hence: 1) Modulating control valves = Regulate flow to maintain constant temperature 2) Flow limiters = Regulate orifice to maintain constant flow

If a valve authority is low, it is similar to filling a glass using a fire hose. As it opens under highly pressurised condition, water will spill over

Hydronic balancing and control

Liquid ΔP sensor across the variable speed pumps

This implementation is very commonly applied in most variable flow systems. Especially the hydronic configuration in the distribution circuits have manual balancing and motorised control valves. In large systems, there may be even manual balancing valves installed in the branches, risers and headers to enable proportional balancing method. The ΔP transmitter located across the variable speed pumps has the following benefits: 1) Easy to troubleshoot 2) Shorter cable length 3) Less need for ΔP 36

transmitter calibration Note: The longer the cable length, the higher the voltages drop. When the analogue signal drops, the range of the control becomes smaller. It was intended to work from 0-10 VDC for a 0-100% pressure variation. In example, the incoming signal becomes 9V DC as maximum after travelling from a long cable distance. Therefore, a calibration must be done to recognise 0-9V DC as 0-100%.

Figure 3-2: Full load condition

During partial load, even the highest resistance or furthest circuit ΔP becomes relatively close to the pump head pressure. At this juncture, the control valve’s character is distorted from its desired authority. When a control valve loses its authority, the temperature response will be unstable and inaccurate. In most cases, it will constantly hunt for the desired temperature. While it is constantly hunting, the average flowrate pumped will be higher than needed. When a system has huge overflow, then the energy transfer across the coil will be inefficient. Most liquid will pass through the coil at high velocity, attributing to less heat transferred. This phenomenon is known as low ΔT syndrome. Low ΔT syndrome will cause the incorrect leaving temperature and quantity of chillers.

ΔP transfer in relation to flowrate

When the cooling load is 70%, the required flow is 40%. When the flow is 40%, then pressure drop across the control valve is 84% with 16% left in the system fittings. A small change of cooling load causes a large pressure transition from system fittings to control valves. Most of the time, the cooling load

Liquid ΔP sensor across the highest resistance unit

A ΔP sensor is installed across 38

the circuit of the highest resistance unit in the system. This unit is sometimes perceived as: 1) Critical unit 2) Index unit 3) Reference unit This practice will enable the speed of the pump to vary proportionally against the pump head pressure.

Climate Control Middle East July 2014

Now that we know the pressure head will vary at the pumps against the system load, it is not possible for manual balancing valves to react to these variations. For example, circuit 1 manual balancing valve is required to create a resistance of 230 kPa during full load. During part load, the available ΔP across the circuit is only 80 kPa. Hence, a manual balancing valve creates more resistance than needed when this terminal requires full flow. It is attributing undercapacity during part load. For engineers, the biggest fear is under-capacity, which is in direct relation to their goals – comfort and efficiency. In this scenario, the VPF system offers the most desirable implementation option. Key to Figure 4: 1) PIBCV – Logarithmic character (water to air energy transfer) 2) PIBCV – Linear character (No energy transfer)

Figure 5-1 shows a construction of extremely innovative technology that performs balancing and control. This control valve has a built-in pressure controller that keeps the control valve character constant. Thus, the good valve authority is close to 1. In combination with its actuator, it has the ability to change the curve of the character to match the coil’s non-linear character; the results of the control will be linear. Linearity signifies stability and accuracy.

Combining PIBCV with other components

Every separate entity in the system has its own characteristic. Combining each component correctly with a properly set and tuned controller elicits a good control response. Not only does it have a good response, but it is also energy efficient. Understanding the basis of the control algorithm helps optimise a chilled water system even further. Example: Chiller leaving temperature setpoint: Decrease the temperature to decrease the overall flowrate. A load analysis of the chillers can be used to determine the leaving setpoint. In a plant that has four

Figure 5-2 shows the flexibility changing the curve in the actuator that could be matched to the coil character. Most actuators in the industry have linear control signal and logarithmic valve character. If different water temperature is fed to the heat exchanger, then its character cannot match.

identical chillers in parallel, the average load of three operating chillers is around 60% each. The chiller setpoint can be lowered to collect and consolidate

the loading of the chillers to decrease the average flowrate. Having lower flowrates would require one set of the chiller deducted from the operation. Now,

two chillers are operating with 90% load each. The objective is to fully load the active chillers and shut down some of the redundant ones.

Most manufacturers produce typically two different valve characteristics based on Figure 6-1. The green colour character denotes the most desired character, which has no ΔP changes, and therefore, has no distortion. A stable and accurate control will require valve authority closer to 1. If a valve authority is low, it is similar to filling a glass using a fire hose. As it opens under highly pressurised condition, water will spill over. If a valve authority is high, it is similar to filling a glass using a tap – a full range of control that precisely provides the exact flowrate that is needed.

VALVES | Part I Control valve authority in practice

Figure 6-1: Common control valve characters

The formula for control valve authority can be expressed as:

The control valve authority is sized with respect to 0.5 minimum commonly as a guideline. Equation 1 has a common expression used based on Figure 6-2: Equation 2 is not a complete expression because the system fittings have not been taken into account. Most of the time, chilled water systems operate two per cent full load and 98% part load. Let us consider the worst case scenario based on terminal unit 4 in the two diagrams: Figure 7-1 and Figure 7-2. In essence, the denominator can be expanded, summarised and translated as in Equation 3.

PIBCV independent of pressure variations Figure 6-2: Terminal circuit pressure drop

Equation 1

Built-in pressure controller, DPC, takes away hydraulic influences from other parts of the installation. Regardless of different load conditions, it maintains a good valve authority. Hence, it can be expressed as in Equation 4.

Figure 7-2: Part load condition

Most of the time, chilled water systems operate two per cent full load and 98% part load PIBCV – a closer look

The primary task of a DP controller is to maintain constant ΔP across the control valve. When the pressure increases in P1, it inflates the bottom part (high side) of the DP controller’s chamber through capillary tubing. During inflation, the DP controller’s orifice becomes smaller to absorb pressure from P1, thus causing pressure in P2 to increase. For pressure transition chart refer to (Figure: 3-2-1). The DP controller will shave off extra pressure applied to the control valve not only when removing hydraulic interference from other parts of the installation, but also when the control valve itself is closing. As long P1 increases, DP controller will instantly react to maintain pressure equilibrium. We notice the DP controller’s chamber is connected to two capillary tubings that are taking both the high and low side pressures. The PIBCV is subjected to atmospheric pressure. Hence, it requires a low side capillary tubing to also achieve atmospheric pressure equilibrium. It doesn’t matter if the DP controller is in front or behind the control valve, as long the capillary tubings are placed correctly across the control valve. (To be continued in the August 2014 issue of Climate Control Middle East)

ustralia has certainly made its mark on the HVACR industry. One of the earliest pioneers of modern refrigeration was an Australian named James Harrison. He demonstrated and patented a commercial ice-making machine in Geelong, Victoria, in 1851. The insights he revealed and the principles he demonstrated with his early vapour-compression systems are, to this day, referenced by refrigeration manufacturers. With many burgeoning industries, such as mining, construction and transportation, Australia is considered one of the foremost growth areas by HVACR industry players. Though market studies suggest that the Australian economy has experienced a slowdown in recent years owing to the recent global economic downturn, many

Chandraraj, whose company has been operating in Australia since 2009, has experienced a six-fold increase in residential sales from the time they set up shop there, and a 40% increase in turnover in the first half of 2014, compared to the same period in 2013. He, however, warns that the market has not always been this rosy. “The market was flat for three years owing to a slowdown in growth in the mining, oil & gas, hospitality and education industries,” says Chandraraj. “The situation was worsened

Most of the HVAC products in demand in Australia are inverterbased by the government-initiated imposition of carbon tax on refrigerants used in HVAC systems.” He, however, adds that the future is not all that bleak: “After the installation of the Tony Abbott Government, there is a possibility that they will withdraw the carbon tax on a retrospective basis. If this happens, it will bode well for the HVAC industry.” (For more information on the Legislation to Repeal the Carbon Tax, see box 1). Samuel Peli, General Manager for Sales at Seeley International, says that despite the reduction in investment and overall business confidence during the crisis years, Australia was not severely affected by the 44

n line with our clear election commitment, the Government’s first item of parliamentary business will be the legislation to abolish the carbon tax. “This will lower costs for Australian businesses and manufacturers, boost growth, increase jobs and ease cost of living pressures for households. “On average, households will be around $550 better off in 2014-15 than they would have been with the carbon tax in place. This is about taking the pressure off of electricity and gas bills. “While the carbon tax will be gone, the household assistance already provided will remain to help families with the cost of living. “The repeal bills will remove the carbon tax, end the carbon tax on fuels used in shipping, rail and air transport and on synthetic greenhouse gases. The Climate Change Authority will also be abolished. “Abolishing the carbon tax will improve Australia’s international competitiveness, which was being undermined by the unfair hit on business. “The legislation will give the Australian Competition and Consumer Commission further powers to take action against businesses that engage in price exploitation following the repeal of the carbon tax. “Repeal of the carbon tax represents a major contribution to the Government’s deregulation agenda by removing around 440 pages of legislation and reducing business compliance costs by about $100 million annually.” *The document is available for the public through www.pm.gov. au

A close look at the market

Most of the HVAC products in demand in Australia are inverter-based, and, unlike in the Middle East, the Australian market notably requires heat pump inverter products. “At Toshiba,” says Chandraraj, “our VRF systems running on allinverter compressors allow us to meet the energy-efficiency standards and requirements in Australia.” In terms of refrigerants, he says that Toshiba has maintained its focus on R410A, though the company is in the process of evaluating the merits of other alternatives, like R32. “Daikin and Fujitsu have gone ahead with using R32 in their products for sale in Australia, but the refrigerant is yet to gain widespread acceptance,” he says. “In fact, it is still not a prerequisite to

eak demand prompted by extreme weather events result in major spikes in electricity usage. These peak events create a problem, as they require expensive investment to increase network capacity. “There are a variety of ways to respond to this problem and manage electricity demand. Demand response through direct load control may allow certain household appliances to be remotely controlled, reducing the demand for electricity at peak times. The approach would be facilitated by mandating that key appliances must be equipped with a demand response interface. This interface would allow the establishment of communication links between appliances and the electricity network. “There are different possible technologies which can allow an appliance to be remotely controlled, and currently many appliance manufacturers are unwilling to risk investing in a particular communications approach unless they know it will be used by other market participants. Mandating compliance with the Australian Standard for demand response interfaces would overcome this and allow sufficient market aggregation to occur.”

use R32 in Australia.” Seeley International also has its gaze trained on energy efficiency to help research and develop its latest products. “For instance,” reveals Peli, “we have developed an Air Handling Unit that uses an indirect evaporative heat transfer core that provides hyper-efficient cooling of outside air.” Peli adds that as it took his company more than a decade to develop the technology, it is confident that the product will offer exceptional cooling and energy efficiency performance. For several years now, Australia

has been employing energy efficiency regulations to pave the way for the development of less power-consuming and more cost-efficient systems. “Australia is a place where most of the products are launched, then adopted throughout the world," says Chandraraj. "The country follows the highest MEP (minimum energy performance) standards in the world, and it is raising the bar every year, since a few years ago.” He says that MEP standards were originally only applied to wallmounted, ducted, ceiling and cassette

units. “This year, however, the authorities are contemplating and studying the inclusion of VRFs and packaged systems to the scheme of the MEP standards,” he says. Peli adds: “MEP standards have been in place in Australia for over 10 years now. Throughout the existence of this regulation, we have noticed a 50% energy efficiency improvement among HVAC products on offer in the Australian market.” In addition to MEP standards, Australia is also reported to be looking at implementing a Demand Response System (DRS) among residential products. “DRS,” says Chandraraj, “will allow regulators and power companies to control the operation of units from a remote location.” In response to the abovementioned initiative, Chandraraj shares the fact that the Toshiba AC lineup for 2014 has already been equipped with DRS (for

more information on DRS, see box, right). While the country is making an aggressive push towards energy efficiency and power consumption suppression, it is also considering harnessing the potential of alternative sources of energy.

The roadmap ahead

The stringent energy efficiency

Climate Control Middle East July 2014

and environmental stewardship regulations in Australia are challenging HVACR industry players to develop products that will satisfy the stringent requirements. While this may be daunting for some entities, HVACR manufacturers in Australia see the introduction of strict regulations as an opportunity to push the

envelope of technological and methodological innovation. As Australia’s economy continues to recover from the effects of the financial correction, HVACR products that promote cost-efficiency and energy and environmental conservation are expected to enjoy higher levels of consumer demand in years to come.

interview BLUE STAR

“Customers want products to talk to them” Satish Jamdar, Managing Director, Blue Star, and Director of Blue Star Electro-Mechanical Ltd, has spearheaded many projects for his company and was responsible for the Service Business, International Operations. He speaks to B Surendar about a wide range of subjects concerning the industry, including VRFs, best practices and business opportunities in the region in light of a palpable market recovery.

India right now. In Muscat, last year, we supplied small units and some in Dubai. In terms of our VRF evolution, we designed digital-scrollbased VRF systems in 2006-

Are you looking for a larger footprint for your VRF technology in the region? What distinguishes your VRF system from that of others in the market? I feel VRF is good, and we are in it. But I think, sort of a blind application of VRF is not necessarily correct. We are able to provide multiple solutions – plain ducted, chiller-cum-AHU…. Depending on energy efficiency, application, and diversity, a horses-forcourses approach is the best. An excessive slant towards any product is not the way forward. It can kill or remove the ability of some of those product lines. I spoke of us being able to provide multiple solutions. In this regard, one-toone inverter technology is becoming popular. Inverterbased ducted units and inverter-based split units in India are very energy efficient, and the fact that they use less refrigerant is good. Inverters are not coming here [into the GCC] 48

Overall, the world is at an experimental stage as regards refrigerants in a big way, and I’m surprised that inverter-based technology has not taken off here, because it can replace splits. Our inverter systems match the five-star rating requirements of ESMA. VRFs of Blue Star are the only ones being sold in

Climate Control Middle East July 2014

Mumbai, India

2007. Then, we launched a revised version that ran on R410A. And now we will be launching an inverter-based VRF system in the next twothree months.

ESMA in the UAE and SASO in KSA are raising the bar on energy efficiency. In a recent interview to Climate Control Middle East, one of the senior directors at ESMA spoke of relegating the current top-star rating standard to a three-starrating status, essentially signalling ESMA’s intent to raise the energy-efficiency standards of products being sold in the UAE. What initiatives is Blue Star taking towards innovations leading to energy efficiency?

The internal guideline for any product of Blue Star is that it has to comply with T3 conditions. And internally we test for 55°C, and we have declared up to 52°C without tripping. We have pushed VRF technology into the GCC with four-five projects in Oman and two-three projects in Dubai. Once our inverterbased VRF system is ready in three months, maybe we will be here in full force next year. All the compressors we are planning are inverterbased. We have an in-house psychrometric lab to test at

design conditions. We can simulate up to 52°C and demonstrate on site. It’s a certified lab. Coming to regulations in the GCC region, regulations need to be consolidated, though. JAFZA, Dubai Municipality, Estidama are examples of different sets of regulations within the same country. Why have so many different approaches if the purpose is the same?

What are Blue Star’s plans and strategies for exporting to the region?

We were getting aggressive in 2009. In fact, in 2008-2009, we opened an office here. India was also growing. We at Blue Star grew four and a half times in this period. Obviously, it was a strain on our human resources, and at the time, all of the GCC was booming. In fact, all the countries around the world were seemingly booming. And the problem of the “Great Recession” hit India in 2008. But India as a country is big, with a large mass. The GDP growth was five per cent. But the Middle East fall was precipitous, and I know there was a lot of turmoil here. So, our ambition to push more products into the Middle East took a backseat. We recently found that the UAE and Qatar have started showing signs of sustainable growth. So we have recaptured our thoughts. For the last six months, things have been getting better. We are seeing a lot of internal investments here and possibly another boom. And whether it sustains or not, time will tell. This region, including Africa wants to come up. So in the Middle East, Dubai could be a good base, especially with EXPO 2020 and FIFA 2022. You have something to sustain with the two events. I think something’s going to happen. There is a decent growth (1520%) on the cards from the base level, and even 40%.

Africa will grow, and the Middle East, therefore, will be a hub. On the flip side, it seems volatile. Iraq has cropped up, and if anything happens, [market] sentiment could drop. We are looking at how to reorient, and this time around, we are going into Africa. We have appointed dealers in Kenya, Sudan and Tanzania. Nigeria is our next target. And so is Uganda. It’s part of a three-year plan. Before that, we looked at SAARC countries. We officially launched in Sri Lanka last year. Maldives, Vietnam, Singapore, Myanmar – that’s also part of the three-year plan. In India, after 20032008 boom, certainly we witnessed a slowdown. It became generally a more

consumer-oriented business rather than investment and infrastructure-oriented business. Sentiment is more positive with [Prime Minister] Modi. We are looking at revival of Blue Star growth in India. Yes, there are hiccups like Iraq, but overall, we should see three to five years of growth. India, the Middle East and Africa are all growing. So we have multiple prongs for growth. We need to get distributorship right in all these countries. Every country has its own standards. So customising the products is essential, and so there is a lot of load on R&D. We might have to add capacity on that front. We are also thinking of options of an assembly line here;

interview BLUE STAR it’s on the drawing board. Having an assembly line in the Middle East will give us flexibility.

Often-times, the issues that keep cropping up in the region have to do with lack of engineering best practices as a standard approach. A few consulting and contracting firms with a fastidious approach does not mean the entire industry is at a certain acceptable standard. What is Blue Star doing to empower and foster engineering excellence, be it related to installation or O&M? R&D, innovations in products, services and manufacturing processes are key strengths. Revival of business sentiment in India has propped up everyone in India. Secondly, we are challenged by regulatory requirements, as we are manufacturers and designers. At the core is the need to look for more

the world is at an experimental stage as regards refrigerants, so the challenge is for us to have multiple prototypes energy efficiency and the need to align with the rest of the world… inverters and Turbocor are the result. Thirdly, we need to

Climate Control Middle East July 2014

consider the work that has gone into the choice of a refrigerant. For four to five years, the pressure was on ODP, and so we moved with 410A and 407C. But soon, people said there is more to it. The auto industry and HVACR industry are driving the change. I can see a move towards a more natural refrigerant, like CO2 or ammonia. Then, there are the hydrocarbons, like HC 290. At an R&D level, we have built a prototype and will be ready to launch in three to four months. And we have signed up with Daikin on the R32 front for incorporating it in inverter split systems. Those we will launch next year in India. Overall, the world is at an experimental stage as regards refrigerants, so the challenge is for us to have multiple prototypes. When everyone is guessing what the next refrigerant is going to be, we are ready with multiple prototypes. ,Some of the refrigerants

that are being used as interim refrigerants now have disadvantages compared to R22. The de-rating of some of the gases is a concern. There is no choice but to be flexible. If two streams of refrigerants are coming up, we would want to straddle both. We want to be refrigerant-agnostic. Customers are intelligent – they want products to talk to them, have automation, remote monitoring of big chillers, which is something we have already accomplished. When sophistication enters the field, we need to be ready with expertise and also smart thinking. Remote monitoring allows us to have fewer experts handling 10-15 projects. Blue Star also has an electronics division, whose concerns include intelligent use of remote, CCTV, video, etc. We are trying to marry these capabilities with the air conditioning side of things.

CHILL

Tu be or not tu beâ&#x20AC;Ś Starting from this issue, we bring you a column dedicated to chillers by Dan Mizesko. We begin with the first of a two-part series, where the writer discusses the advantages and disadvantages of enhanced and super-enhanced tubes. The concept of utilising enhanced tube technology to reduce energy consumption, thereby reducing utility costs has been in use for over 30 years. The most recent breakthrough in heat transfer tube technology has been the use of a combination of internal rifling with roll-worked external enhancements to increase heat transfer. This practice has resulted in a significant reduction in energy consumption.

Challenges

As this new technology expanded into different areas of industry, new challenges had to be overcome. New designs, such as enhanced and super-enhanced tubes, require that the heat transfer medium, ie, water, be of a higher quality than ever before. These changes demand exceptional water treatment programmes, as well as operational and maintenance practices. Based on my experience

For best results, your specialist chiller service company should be actively involved in your water treatment programme

working throughout North America, Mexico, South America, the Caribbean and the MENA region, I believe that the condenser tube conditions in the MENA region is by far the poorest I have seen. The reasons for this are many, but the main factors are misinformation and varying and incorrect opinions regarding proper water treatment, CoCs, how the chillers are operated, how offline chillers are addressed, and tube maintenance. I am not going to address water treatment or water treatment technologies in this article. However, I would like to caution that for best results, a specialist chiller service company should be actively involved in your water treatment programme.

Why enhanced tubes to superenhanced tubes?

Enhancing of tubes to increase heat transfer rates have been promoted since the 1970s, mostly based on the following mechanical engineering principles: 1. Making a thinner wall with structural integrity can provide more efficient overall heat transfer by reducing the resistance through the tube wall. 2. Increasing turbulence of flow close to the heat exchanger surface can turn over the fluid faster, providing increased heat transfer. 3. Increasing the surface area on either side of the heat transfer surface will provide increased heat transfer. The first enhancements of straight bore tubes came with the insertion of internal vanes to improve flow characteristics. These design modifications were only moderately successful in increasing heat transfer efficiency. However, these devices were more prone to

fouling, which decreased their functionality. The next generation of enhanced tubes was a rifled barrel effect with fins, both on the outer and inner tube surfaces. The fins, depending on the manufacturer, varied in height, width, numbers per inch, and change in pitch. These factors changed the velocity profile of the water on the interior surface of the tube. Most of these tubes had a decreased wall thickness (up to 50%). Their increased surface area over the straight bore tube (by about 50-70%) resulted in claimed improvements in energy efficiency up to 40%. The most recent generation of tubes (super-enhanced) have a rifled barrel effect

with fins on the internal part of the tube and a waffled-type structural effect (roll-worked external enhancement) on the outside. The external structure has been referred to as external fins or external enhancements. The fins on the inside vary in height, width and number per inch, while the waffling effect provides an even greater surface area and reduces the wall thickness in some areas by up to 70% from the straight bore tubes. It is evident that the main advantage of enhanced and super-enhanced tubes is energy savings. All new centrifugal chillers have this technology in their chillers.

The disadvantages of the technology According to the AWT

reports, a representative of a major chiller OEM indicated that his major concerns were with water quality. He stated that a side-by-side comparison of a system with enhanced tubes to a system with straight-bored tubes would show a significant difference in the amount of heat transfer efficiency lost due to a thin layer of scale in the enhanced tubes. The straight-bored tube system may lose about 10-15% heat transfer efficiency, whereas the enhanced-tube system could lose as much as 20-30% heat transfer efficiency. Because of this greater susceptibility to scaling in the enhanced tubes, water quality and the associated water treatment programme need to be first

rate. If not, the efficiency gained from the purchase of an enhanced tube system will be lost in a few months.

PROCESS INSTRUMENTATION

Process instrumentation â&#x20AC;&#x201C; a critical DC infrastructure Diagnostics and better predictive maintenance ensure the efficient functioning of a District Cooling plant. Laxman AR posits the view that process control instrumentation helps achieve this.

he early years of the past decade saw an upsurge in the District Cooling concept as an alternative to traditional air conditioning methods in the Middle East. The infrastructure boom in Dubai during this period tested the sustenance of the concept. After the intermittent cool-off period, post 2013, the market has once again started to warm up. As per estimates, a capacity of approximately five million TR is expected to be added in the next fiveyear period, mainly in Saudi

Arabia, Qatar and the UAE. Over the years, one of the major contributors towards this success has been the role of process control instrumentation, which is classified among the critical infrastructures in a District Cooling plant. With the earliest plants, the control philosophy adapted a more conventional approach of the analogue signals from the discrete devices hooked on to the controls. However, with PLC (Programmable Logic Controller) gaining more acceptability in the control domain, open digital communication, STOCK IMAGE ONLY

Advancement in the instrumentation technology related to District Cooling plants has paved the way for reduced engineering costs like PROFIBUS, heralded the arrival of newage technology to the instrumentation and control domain of the District Cooling architecture. Advancement in the instrumentation technology related to District Cooling plants has paved the way

for reduced engineering costs, complexity of cabling, increased process diagnostics and better predictive maintenance. New generation devices, with their modular electronic concept, have enabled easy replacement of devices, improving plant availability and a more safe and reliable performance of the plants. In a typical plant lifecycle, OPEX costs are estimated to be more than 70% of the initial CAPEX; this is also true for a District Cooling plant. Water constitutes nearly 25% of the operating costs in District Cooling, and it is imperative to monitor both the quantity and quality of this resource, which is used in a closed loop. With the advancement of new trends in water treatment, and with local legislations keen on promoting the use of treated water, polishing plants have now been included in the existing infrastructure. This trend has added to increased instrumentation assets. Judicious selection of a partner who can bring in innovative products and solutions along with a proven track record complementing with local competence and service support plays a pivotal role in reducing the overall cost ratio for this critical infrastructure.ď&#x20AC;ź

PRODUCT PIRACY

BEWARE OF COUNTERFEITERS! Product piracy is a menace plaguing the HVACR industry the world over. Bitzer, Kühlmaschinenbau, warns about the dangers of using cheap imitations and shares information about his company’s ongoing initiative against fraudsters.

ounterfeits have become a mass phenomenon. In addition to complete compressors, using counterfeit compressor spare parts and fake refrigerants is on the rise worldwide. This is unacceptable because, unlike with counterfeit watches or handbags, technical applications can be very dangerous when pirated products of poor technical quality are used. Apart from safety, the issue of performance clearly takes centre stage. Cheap copies lead to poor performance and play a key role in the customer’s purchasing decision. Particularly in Asia, unscrupulous product counterfeiters now even go as far as copying the catalogue data of companies, which misleads buyers. However, in the long run, the supposedly cheaper copies prove to be much more expensive than the originals, as they conceal another risk for users – the low-quality components significantly reduce both the service life and reliability during operation. More significantly, all these factors negatively impact the entire industry. Unfortunately, product

piracy has achieved highly professional results in the industry. Experienced counterfeiters copy originals with a level of perfection that makes it nearly impossible to tell them apart from the original. We are dealing with a network of counterfeiters and distributors who sell very authentic-looking copies all over the world. The criminals pretend to be partners of reputed

Climate Control Middle East July 2014

companies and, thus, harm both the company and the customers. However, while they make fakes look the same as originals, when it comes to quality, the poorly constructed components cannot withstand the high demands and will likely experience limited functioning after a short period of time or be completely defective and require repair.

The use of fake compressors, spare parts and refrigerants has already led to personal injury and death in the transport cooling industry. What’s more, there’s a risk of motor damage, liquid slugging, heat damage and short circuits, which are often irreparable and can only be identified with in-depth analysis. What is important, when copied spare parts are used, the warranty becomes void for the entire product. The Bitzer Group, manufacturer of refrigeration compressors, has decided to wage war on product piracy by taking a more proactive approach to dealing with counterfeiters, especially compressors, spare parts and pressure vessels. The Bitzer Green Point offices are expert contact representatives when it comes to issues of compressor repair and provide customers worldwide with professional support in service, maintenance and training. As such, we can monitor the entire lifecycle of our compressors and pressure vessels all over the world. Also, we are increasingly taking legal action. Suppliers of fake products are always thrown out of trade fairs and have to remove our logos immediately. Because it’s difficult to differentiate between an original and a copy visually, we are now introducing a diverse range of measures to make it possible to clearly tell them apart. This will help to protect people’s lives and the commercial interests of both the company and the customers. Finally, we strongly advise against accepting unusually cheap offers for compressors, spare parts or refrigerants.

CODEX HACCP

HACCP and/or HACCP texts • A draft project document for new work by CCFH (Source: http://www.fsis.usda.gov/wps/ wcm/connect/fsis-content/internet/ main/topics/international-affairs/ us-codex-alimentarius/archives/codexnews-022114)

GHP and HACCP

Reflections on the Codex HACCP Colloquium Dr Joanne Taylor was invited to present at the Codex HACCP Colloquium, held in early June in Finland. It was a platform for experts across the globe to come together to discuss the Codex Food Hygiene Text and recommend changes to the Codex Committee. Dr Taylor shares with us a few of the salient points raised there.

The background

The Committee on Food Hygiene (CCFH) invited Codex members and observers to participate in a scientific colloquium, sponsored by Finland, in Kirkkonummi, Finland, from June 4-6. The colloquium was avowedly in response to Finland specifically asking

during the last session of the CCFH, held in Hanoi, Vietnam, last November, to consider an update of the General Principles of Food Hygiene (CAC/RCP 1-1969), and especially of its Annex on HACCP (Hazard Analysis and Critical Control Point), and regard it as new work. To clarify which parts were

Climate Control Middle East July 2014

most in need of an update, and what might be missing from the Codex texts, Finland proposed to host a scientific colloquium for a limited set of experts with the following likely outcome: • An outline for a discussion paper on the need to update the General Principles of Food Hygiene

It would be useful to focus on a “Food safety management system” with GHP (Good Hygiene Practices) and HACCP as two interlinking parts. Here, flexibility is important, as some businesses may only need GHP or need a gradual approach to HACCP. However, all approaches must be validated.

Hazard analysis is the most difficult step, but the least understood It needs to be noted that the Codex text is written with a manufacturing bias, and needs to better reflect SLDBs (Small and/or Less Developed Business). It must be re-emphasised that GHP/PRP (Prerequisite Programme) must be implemented adequately prior to HACCP, or there is no HACCP system. It must be highlighted that non-Critical Control Points (CCPs) still require control. Chemical and physical hazards should be separated and more emphasis placed on chemical hazards. It needs to be pointed out that many countries take the Codex text and follow it directly, which leads to problems, as different systems are needed

perspective for different types of businesses. You can comply with the HACCP principles without a HACCP plan, and you don’t need to call it HACCP. Also, the document does not need to be linear; there could be links forward and back.

Hazard Analysis

Hazard analysis is the most difficult step, but the least understood. It would be a good idea to add Hazard Analysis to the general text, as well as the HACCP text. A new document could, thus, be created, similar to the validation document. The following are a few of the recommendations made during the sessions: • Training is essential, for the competent authority, as well as businesses. • Effective hazard analysis

is essential prior to CCP decisions. Greater support is needed for SLDBs (eg, the competent authority undertaking hazard analysis, generic/evolving HACCP). More information, guidance and tools are needed for deciding the significance (which is not necessarily a Codex responsibility). Guidelines are needed on the scale of severity and likelihood [of hazards]. It is not the listing of hazards that should be the focus; prioritisation needs to be the focus. Clarity of terminology is needed, for example, Risk Assessment, Risk Analysis, Hazard Assessment and Hazard Analysis. Greater explanation is

Finger on the

DC pulse DC Serve, dealing in District Cooling equipment and services, was formally launched during The Big 5 2013. It is now poised to take advantage of the improvement in market sentiment in the wake of the nascent economic upturn. B Surendar has the story...

“D

C Serve was born out of an integration of products and services to give District Cooling customers a onestop-shop,” says Rennie Sequeira, the Division Manager responsible for the District Cooling initiative. DC Serve is a part of the Faisal Jassim Trading Company and is backed by a group that specialises in

engineering, manufacturing and trading of building services equipment. “At Faisal Jassim, we trade in heat exchangers, cooling towers, filtration systems and balancing and control valves,” he says. “With an increase in demand for District Cooling services and the fact that several District Cooling projects are being revisited (during this nascent economic upturn) that we are seeing, it is very important to offer all these services under one umbrella to showcase our sales team and our specialised supply, installation and maintenance capabilities,” she explains. DC Serve serves MEP contractors, consultants, utility providers and FM companies, and is at present focused on the UAE and Qatar. The company evidently means business, going by its list of clientele: Emicool, Empower, ADC Energy Systems, Stellar, TransGulf ElectroMechanical and SNC Lavalin. “We have diversified into infrastructure, as well, and we have reputed manufacturers supplying us,” Sequeira elaborates. With its present product range, the company can service projects of up to 40,000 TR. “For instance, we would have limitations on valve size when it comes to projects of 300,000 TR, but of course, we can handle it if it were to be broken down into distributed cooling schemes,” Sequeira claims, and adds: “When we sell our products and services, we take a holistic view. We do system design and value engineering and do not have a mere product focus.” The avowed twin objectives of the company, apart from, of course,

being a viable commercial entity, is to demonstrate to customers the value of using reliable products and how to save water and energy and reduce Opex. “One of our products even has an ROI calculator, and we can demonstrate and convince the need for quality products and not to compromise on quality,” says Sequeira. "When it comes to services, we can overcome the Low Delta T Syndrome only if there is good hydronic balancing,” he explains. “And when it comes to evaporation loss or drift loss, we look at how we can save water.” The company also maintains cooling towers, does maintenance work to improve heat transfer and performs gap analysis. “Overall, our focus of services includes ETS (energy transfer stations), hydronic distribution and cooling towers,” Sequeira reveals. Can the industry begin to revive its faith in District Cooling and afford to be sanguine about it? Sequeira believes that there is great potential for the industry, especially with Dubai winning the EXPO 2020 bid. However, to increase the penetration of District Cooling in the overall cooling market, he believes the way forward is to make people more aware of its benefits. “Currently, I agree, the monetary savings of District Cooling are not being passed on to clients,” he concludes. Positioning itself as a company that deals in marketing, installation, after sales service and maintenance, DC Serve hopes to overcome this lacuna, while targeting a bigger share of the District Cooling pie.
