Changing consumer patterns and increasing awareness is shaping the growth of the air conditioner and refrigerator market, a sector that accounts for a whopping 65 to 70 per cent of all business in Oman’s white goods market
he importance and size of the global commercial air conditioning (CAC) market has grown to prominence in recent years, gradually evading the shadow of the residential air conditioning (RAC) market. Such growth has not been limited

by tempering market conditions in the traditional CAC strongholds of North America, Europe, and Middle East. With demand for CAC products accelerating in other parts of the world, other regions have now entered the fray.
However, Air conditioning is a necessity in the Middle East, given its geographical location, climatic conditions and the ever-evolving infrastructure. Massive construction drives which spurred the development of numerous residential and commercial real estate projects, and high population growth have fuelled demand for air-conditioners and cooling systems in the region. The region’s annual commercial air conditioning (CAC) market volume is expected to reach approximately $4bn, a 35 per cent growth from 2010. Regional construction boom and increasing investments from China have boosted the growth. Another factor is the 2022 Qatar World Cup, which has greatly increased construction in Qatar in preparation for the mega event in the region. This directly translates to a need for CAC in a region that experiences hot and humid conditions for most of the year. The boom in real estate development together with the growing emphasis on greater cooling facilities and the resultant increase in power demand have all contributed to creating huge opportunities for manufactures and distributors in district cooling. This trend has received added impetus in recent years with the lack of sufficient generation, transmission and distribution infrastructure to meet projected power demands. In Oman, the air-conditioner and refrigerator market account for a whopping 65 to 70 per cent of all business in the white goods market. The market size of air-conditioning products is around 200 K units a year in Oman. The market size for Refrigerators is around 80 K units a year. Also due to a very fertile commercial /
industrial projects scenario, there is also a great business opportunity for different air-conditioning concepts like chiller, ducted type or DVM(digital Variable Multi. Traditionally, the Sultanate has been a market for window ACs. That trend is rapidly changing as improved standards of living and more sophisticated lifestyles push customer preference to split and ducted air-conditioners. This is in line with global trends. Apart from lifestyle changes and economic development, price reductions in split units have driven demand for these models of air-conditioners. What’s more, the air-

has been developed and implemented throughout the GCC.
Environmentally friendly Industrial outlook has shifted towards a greener and more sustainable future, requiring customers as well as manufacturers to truly focus on environmentally-friendly technologies. In 2011, Sharp launched its latest AC technology in Oman, with the addition of ‘All Aluminum heat-exchangers’ and ‘Plasmacluster Ions’ into its line-up of ACs. This innovation not only reduces the unit’s weight by 40 percent, it also reduces its refrigerant requirement by a staggering 50 percent. “Sharp has always focused on improving customer’s lives through its technologies and we used this launch to showcase yet another innovation to the local and global market, which we believe tackles some of the challenges faced by the AirConditioning industry in the region,” says AG Tony assistant general manager OMEC.
World’s first tropical inverter AC Panasonic has recently introduced the world’s first tropical inverter air conditioners which are designed to specifically meet the climatic challenges of the Middle East. The new range of air conditioners comes with the Smart Inverter Compressor, which are powerful, fast and extremely energy efficient. With searing temperatures in the region, the new technology has made it possible for an 18000 Btu air conditioner to reach up to
4
DOSSIER – Guide to Air-conditioning & Refrigeration 2012-13
22000 Btu, and a 24000 Btu model to reach up to 27000 Btu, based on the requirements resulting in faster cooling. Furthermore, the new technology precisely manages the speed of the compressor, resulting in up to 30 per cent less energy consumption compared to a non-inverter model.
Crystal cooling Samsung’s Crystal AC combines unsurpassed technology and breathtaking beauty. The Crystal AC improves the quality of air while cooling to provide the utmost in comfort. Powered by Comfort Care technology, the Crystal air-conditioned range features a Multi-Step filter which dramatically improves air quality to protect health. Comfort Care adjusts humidity while cooling in conjunction with an Ideal Comfort Index, to ensure cool comfort all the time. The Smart Saver function automatically operates the AC in the least amount of time necessary to cool the room, saving up to 31% electricity while protecting the environment.

running time, while maintaining the optimum temperature.
General’s wall mounted split AC Oman was the first country in GCC to have the honour of launching “General” 5 speed control wall mounted AC in May 2011. The new “General”, designed with its innovative technology, reduces resistance to return air, thereby allowing more air contact with the Heat Exchanger which results in better cooling. This 5-speed wall mounted split AC has a wide range of fan. ‘Airflow’ or quite simply Air movement inside a conditioned space is one of the key factors that contribute to ‘comfort’. The airflow reaches up to 15 metres, and gives a better cooling effect in to unwieldy longish rooms. Besides being environment friendly, this new model also incorporates additional heat exchangers, which means even better cooling performance, while consuming lesser energy, giving users handsome savings in electricity bills.
RF Systems and Multi V The heating, ventilation and air conditioning (HVAC) industry has moved steadily beyond

simple air conditioning units for households and into more intricate and sustainable systems that cover entire buildings. Riding the wave of this trend, variable refrigerant flow (VRF) air-conditioning systems have proliferated widely. Despite their humble beginnings more than 20 years ago, VRF systems have now evolved into advanced air conditioning systems that provide customizable temperature control for all occupants within a building or building complex. Speaking at the launch of LG’s VRF system Multi V III commercial air-conditioner earlier this year, HS Paik, President of LG Electronics Gulf FZE said, "As a company with a strong focus on producing energyefficient products, we feel that the MULTI V III addresses all the major HVAC requirements of b businesses in the Gulf. With this product, we are in a strong position to work with our dealers and business partners in the region to make LG the leading provider of smart and efficient HVAC solutions. And, this has definitely proved to be the case as the Multi V III has earned $15m so far since it was released in the Middle East.
VRF sales in 2011 grew 500 per cent compared to the overall single air conditioning market›s 21 per cent growth. The sales of this system continue to grow steadily as the expansion of the Middle East CAC market. Advances in technology and growth in the HVAC market have gone hand in hand as greater demands have necessitated bright ideas and the effective implementation of those ideas. This is reflected in the growth of VRF systems worldwide. The VRF systems market globally averaged an annual growth of 15
VRF SALES IN 2011 GREW 500 PER CENT COMPARED TO THE OVERALL SINGLE AIR CONDITIONING MARKET'S 21 PER CENT GROWTH per cent over the last five years and reached an impressive $4.3bn in 2010. Much of the initial growth was seen in major markets, but there has been a noticeable shift to emerging markets. This trend has led a growing number of industry observers to predict considerable growth in the future. According to research conducted by LG Air Conditioning and Energy Solution Company, the VRF systems market will reach a staggering $7.3bn by 2013, a 40 per cent jump from last year›s tot. Midea has also emerged as a leader in variable refrigerant flow (VRF) systems with most of the big names in world buying from them under their brands. MDV-D is Media’s
range of VRFs which unlike many others is the new generation of multi-modular systems for commercial and residential air conditioners that uses the ‘digital scroll’ technology. A digital scroll system is a multi system with a DIGITAL SCROLL Copeland compressor which is able to simplify air-conditioning systems, regulate efficient performance and save more energy by digitally regulating the output to the required capacity as multiple indoor units can be connected to a single outdoor unit and these indoor units can be controlled independently and collectively.
Latest VRV Daikin’s VRV III series has specially designed models for high outdoor temperatures, with an extensive capacity ranging from 8 to 36 HP. It was Daikin which developed the world’s first variable refrigerant volume system (VRV), maintaining a nearly constant room temperature without the typical temperature fluctuations It is equipped with advanced built-in intelligence and flexibility. The unit can operate in adverse conditions where the temperature reaches as high as 52°C. This series incorporates Daikin’s latest technologies, including long piping and high external pressure, to meet the diverse needs of our customers.
Reliable compressors Wansa air conditioners have silent and highly reliable compressors. Their built-in air filter not only kills bacteria but removes dust, pollen, mould and any airborne particles. The active carbon filter eliminates odours and deactivates harmful chemical gases in the air. It also traps common household air pollutants such as dust and smoke. The sleep /economy mode lowers or raises the room temperature setting by one degree.

PORTABLE COOLING
Versatile Solutions Portable air conditioners provide many advantages over traditional units, especially in rented or temporary interiors as well as smaller spaces. They can be easily moved and offer flexible choices and can be adapted to suit individual needs
A
ir conditioners have become an indispensable part of everyone’s lives. And today there are certain portable air conditioning units that offer the same features as you would find on the much larger versions. What many people do not realize is that these portable air conditioning units provide them with the same benefits to be had if they had the traditional air conditioning units installed. Portable Air Conditioners are a good choice for smaller homes or rented homes as they do not need to be permanently fitted into a wall or window. They can be easily moved and offer flexible choices and can be adapted to suit individual needs. Some of the benefits of portable air conditioning equipment: – These units are very light so you have the option to be able to move them around easily from one room to another. This means that you can then move them into the room where they are needed the most just by pushing them along the floor. – They have far less internal parts within them and so they don’t need to be maintained or repaired as much. In fact you will end up saving quite a bit of money each year because you won’t have maintenance costs to contend with each year as you would with the larger units.
8
DOSSIER – Guide to Air-conditioning & Refrigeration 2012-13
Plus they tend to be a lot less complicated so many people find that they are able to maintain them and carry out any repairs themselves. – A further reason why it is worth getting portable air conditioning units is they don’t need as much electricity to power them. So this means that you electricity bills each year when the units are being run won’t be as high as if you were to have traditional air conditioning units installed. – The majority of air conditioning units available today come with special ducting which ensures that any warm air is taken out of the room where the system is situated. This again helps to keep the cost of cooling the room down low. When it comes to you buying a portable air conditioning unit there are several places where you can get them from including regular stores and specialised air conditioning companies. But the amount you spend on yours will depend on a number of things such as the make, size and model of the unit as well as what special features you need yours to have. But the best option for those wanting to keep costs down is to go for smaller more basic models.
Installation You need to consider the area of the room before installing a portable air conditioner. One which is too small will be insufficient and a very big one would be inefficient and expensive. Make sure that the air conditioning unit you choose has enough power for the task. Match the machine to integrate to your home needs and choose an energy efficient design. Most portable air conditioners can cool up to 400 sq ft with little effort. The general guidelines for room
size in selecting a portable air conditioner are 7500 BTU for 150 square feet, 9000 BTU for 200 square feet, 1000 BTU for 250 square feet, 12000 BTU for 350 square feet and 13000 BTU for 400 square feet. During summer, a time when overworked HVAC systems become prone to failure and portable air conditioners could become handy. They can provide solutions to a range of heat-related and comfort challenges yearround also.
Equipment Types There are two main types of portable air conditioners in use today. The first type is air-cooled portable air conditioners, which exhaust hot air through ductwork. They are the most commonly used equipment because they can be installed almost anywhere, usually in minutes. They are preferred over water-cooled units where water leakage, no matter how unlikely, would be catastrophic. The second type is water-cooled portable air conditioners, which connect to an external water source. They are best-suited for use in facilities with central cooling towers or chiller systems or where the municipal water supply is plentiful and economical. Watercooled systems do not require exhaust ducts, so they often are preferred when there is no convenient way to exhaust hot air out of a room (e.g., in restaurants).
Applications Besides emergency backup, a common application for portable air-conditioning units is bridging gaps during construction or renovation when a central HVAC system may be shut down or not even be installed yet. Now portable cooling can provide relief to construction crew also.

PORTABLE COOLING
Special events also can benefit from portable cooling. Tented weddings and parties require more cooling capacity than typical building applications because of the heat loads generated by large crowds. A good rule of thumb is one ton of portable cooling for every 125 to 175 sq ft of tented area.
Equipment-selection factors There are many things to consider when selecting portable cooling equipment. Proper selection starts with equipment sizing, defined as cooling capacity in British thermal units per hour or tonnage (12,000 Btu = 1 ton of cooling). Heat-load factors unique to the application for which the air conditioner is meant must be taken into account when selecting. Every portable air conditioner is designed for use with a particular type of electric circuitry, so the available power supply will impact final equipment selection. If the air conditioning unit is to be located inside, the first question is whether to use one or two ducts. For some applications, it is advantageous to use a single duct coming off the top of the unit to vent warm air into the return-air plenum or out of the space. If the building uses night/weekend temperature setback, it is best to put a condenser plenum and additional duct on the unit so there are two ducts going to the drop ceiling. If a unit must be located outside of the space to be cooled, find a way to get the return and cold-air supply inside.
10
DOSSIER – Guide to Air-conditioning & Refrigeration 2012-13
This might involve cutting openings in drywall to insert ductwork. If the portable installation is temporary, alternative solutions (e.g., going through windows or other existing openings) can be found. Another consideration is how to dispose of the condensate water created by the cooling process. This can be done by using a standard condensate tank or bucket that comes with a portable cooler or by running a condensate line from the unit and pumping the water to an external drain. Beyond energy-efficiency issues, there are some other factors to consider when buying a portable air conditioner. Since all the mechanical components on a portable unit are inside the room, the potential for noise is even greater. Moisture is another issue. The water that accumulates during the operation of a portable air conditioner goes into a drain tank. Most use this water to cool the condenser coils so it gets evaporated and discharged through the exhaust duct. However, some designs don’t use this water, so you must empty the tank once or twice a day during normal usage. Given these downsides, we suggest you consider a portable unit only if having a window unit is out of the question and a split ductless system is not viable because of cost or installation concerns. If you do decide to buy a portable unit, choose a model that has two hoses and evaporates the condensed water.
MAINTENANCE
A Long-term Strategy Making air conditioners last requires proper operation and maintenance. Here’s a look how
T
he maintenance of an AC is an area that most consumers and commercial clients need to learn about. It is not always necessary to order dealer service when a little bit of care and maintenance on your part will go a long way in improving the working life of your air conditioner. Simple things such as regular cleaning of the filters, helps increase the life of your AC. However, it is more prudent for you to enter into an annual maintenance contract with the authorised service centre of your brand of AC, so that the units are maintained at a nominal cost with little hassle. Understand that an air conditioner, apart from cooling, also conditions the air inside your room like humidity, dust, order, fungus, bacteria, etc. All good quality ACs have cooling, humidity control, dust removal, anti fungal and anti-bacterial functions and these need to be used properly. Split ACs are now affordable, very quiet and energy saving as compared to window ACs. They are also more hygienic and prevent birds from making their nests in air gaps, rodents creeping in and air from leaking. Clean the filter of your AC once a fortnight, or when the indicator lamp on the front panel lights up. Dirty air filters force your system to work harder to push cool air through your home. This uses more energy and places extra strain on the air conditioning system. Take
the filter(s) out and hold it to the light. If the dust on the filter is so think that you can’t see much light shining through the filter, it’s time for new filters. A clean air filter, unobstructed by the dirt and other debris, will save you money on energy costs and prolong the life of your air conditioner. Keep the doors of your rooms open for a few minutes every day to allow some fresh air to enter. Do not spray any type of deodorant or perfume into your split ACs. Doing so will result in foul smell, necessitating a cleaning of the indoor unit. For safety, always turn the thermostat and outdoor unit’s breaker off before doing any work around that outdoor unit. The coil can be cleaned using a soft-bristle brush to gently sweep the fins. Always brush in line with the fins, and be gentle because the fins can bend easily. Because the fan pulls air through these fins, you can expect to find dust clinging to the fins. Removing this dust and other debris will reduce resistance and increase efficiency.

TECHNOLOGY
H
eating and cooling loads are the measure of energy needed to be added or removed from a space by the HVAC system to provide the desired level of comfort within a space. Right-sizing the HVAC system begins with an accurate understanding of the heating and cooling loads on a space. Right-sizing is selecting HVAC equipment and designing the air distribution system to meet the accurate predicted heating and cooling loads of the house. The values determined by the heating
and cooling load calculation process will dictate the equipment selection and duct design to deliver conditioned air to the rooms of the house, right-sizing the HVAC system. The heating and cooling load calculation results will have a direct impact on first construction costs along with the operating energy efficiency, occupant comfort, indoor air quality, and building durability. An accurate evaluation of the heating and cooling loads requires a complete understanding and accounting of the building components that make up the thermal enclosure along with the outdoor/
Often, cooling load calculations are estimated by the ‘rule of thumb’ instead of utilising conventional protocols and more often than not over sizing comes with its own set of disadvantages

indoor contributions to the load. The load calculation for a house where the building enclosure has been enhanced with added air tightness strategies, better windows, and additional insulation will be more sensitive to manipulation of the inputs. Historically, energy codes did not address stringent levels of energy efficiency, and rules of thumb were developed for HVAC sizing that worked based on the construction at that time. Building enclosures have become more and more energy efficient as energy codes have become more stringent since 2000, but these rules of thumb have not changed. Full credit should be taken by the HVAC system designer for improvements such as better windows, enhanced air tightness strategies, and additional insulation. Many HVAC companies rely on the “400 square feet per ton” rule for sizing systems. Even when a load calculation is required to be performed, the contractor may often manipulate the inputs to get a result that is close to the “400 square foot” rule of thumb. Overcoming this bias requires the builder and their trade base sharing an understanding of the importance of achieving the stated building enclosure specifications, and undertaking visual inspections and testing during construction to verify the building meets the intended level of performance. When these checks and balances are in place, the perceived need to add factors of safety during the heating and cooling load calculation process can be avoided. Peak cooling loads represent the amount of heat gained by the house from the outdoor environment at design conditions, which must be removed by the HVAC system to maintain occupant comfort. Cooling loads
are made up of the sensible and latent heat gains. The mechanisms of heat gain are conduction, infiltration, ventilation, and radiation.
Risks Associated with Oversizing Oversizing the HVAC system is detrimental to energy use, comfort, indoor air quality, and equipment durability. All of these impacts derive from the fact that the system will be “short cycling” in both the heating and cooling modes. To reach peak operational efficiency and effectiveness, a
OVERSIZING THE HVAC SYSTEM IS DETRIMENTAL TO ENERGY USE, COMFORT, INDOOR AIR QUALITY, & EQUIPMENT DURABILITY heating and cooling system should run for as long as possible to meet the loads. An analogy is that of a car: highway driving at a steady speed will get the best fuel economy, while speeding up and slowing down puts undue wear and tear on the engine and braking systems, and reduces fuel efficiency. First Cost, Energy Costs and Durability: An oversized HVAC system will have both a higher initial cost and a higher cost of operation. The frequent starting and stopping of short cycling can also lead to premature failure of the equipment. Comfort - Space Temperatures: Short cycling limits the total amount of air circulating

The cooling system removes moisture from the air by passing the air across a condensing coil. The system must run long enough for the coil to reach a temperature where condensation will occur and an oversized system that short cycles may not run long enough to sufficiently condense moisture from the air. Excess humidity in the conditioned air delivered to a space may lead to mold growth within the house.
through each room, and can lead to rooms that do not receive adequate duration of airflow. Short cycling of an oversized system can lead to comfort complaints when the spaces located further from the thermostat do not change temperature as quickly as spaces near the thermostat. Even in an energy-efficient house with an enhanced thermal enclosure, this can lead some rooms being colder during the heating season and warmer in the cooling season. In attempt to make the spaces further from the thermostat more comfortable, the occupant may set the thermostat set point higher, requiring additional energy. Comfort - Humidity Control: The risks associated with oversizing the cooling system, particularly in more humid climates, are also a concern. In the cooling season in humid climates, cold clammy conditions can occur due to reduced dehumidification caused by the short cycling of the equipment.

Manual J and Manual D are specific protocols used to determine how much heating/cooling a home needs to stay cool and dry in the summer and warm in the winter. This load calculation process was developed by engineers in the heating and air conditioning industry and has been used for decades to accurately size heating and air-conditioning equipment. After completing this load calculation process, one can choose a properly sized piece of machinery to satisfy the load. However, the requirement for Manual J and Manual D calculations is widely ignored and rarely enforced. Most residential furnaces, boilers, and air conditioners are still sized by rules of thumb instead of careful calculations. As a result, almost all of the HVAC equipment installed is oversized. Oversizing typically ranges from 30% to 200%. The main reason to choose right-sized equipment is to avoid paying too much money for equipment you don’t need. A Manual J calculation will ensure you don’t spend more than necessary for your air conditioner. Moreover, a Manual J calculation will provide room-by-room heat loss and heat-gain information that is essential to good duct design. Without good duct design, you’re running the risk of comfort complaints.
BUYING GUIDE
Timely Decisions While buying air conditioners, a majority of consumers tend to choose an AC based on its cooling qualities ignoring the quality of air
A
s the heat turns up and thermostats turn down, many homeowners begin the process of choosing a new air-conditioning unit or replacing an old one. When you buy an AC, make sure the unit is tropicalised (designed for Middle East region’s high ambient conditions), the after-sales support is strong, the power consumption and noise level is low, the unit has air-purifying capabilities, the design complements the interior of the room and it matches your budget. A majority of buyers tend to choose an AC based on its cooling qualities and ignore the quality of air. Some of the new ACs in the market provide air purifying functions which also removes allergens from the air thereby increasing the quality of air. Air conditioners in the Middle East are used primarily for cooling. Always consider the following main factors – the cooling requirement, the room size (area, height and exposure to sunlight), the climatic conditions and the number of occupants in the room . The room size and climatic conditions determines the BTU requirement to cool the room. BTU stands for British Thermal Unit, defined as the amount of heat necessary to raise the temperature of one pound of water by one degree. The heat gain added to a room by a person at rest is about 230 BTUs per hour. So a 10,000
BTU air conditioner is capable of removing 10,000 BTUs of heat per hour. The higher the BTU rating of an air conditioner, the easier and faster it is to cool a room. International standards recommend approximately 30 BTU per square foot of the room, but in Gulf weather conditions at least 90-100 BTU per square foot are recommended. Split air conditioner: When cooling rooms with uninsulated ceilings, great rooms, or southern or western room exposures, step up to the next BTU size. If a building is not centrally air conditioned, a customer has three options: a split, window or portable air-conditioner. A window air conditioner is a single unit with its components housed inside the unit and it requires no inter piping for installation. The AC can be installed through an opening in the wall. The main benefit with this is the ease of installation as the split air conditioner has two parts, the outdoor condensing unit and the indoor fan coil unit. A split air conditioner can be a single split unit where one fan unit is connected to one condenser or multi split unit where one condensing unit is connected to more than one fan unit. Since the split units have an outdoor condensing unit, they are quieter in operation. Portable or selfstanding units are small units used in spaces where installation is difficult.

Rooftop Packaged AC Terrace garden Daikin’s rooftop Packaged ACs (PA) uses R-410A refrigerants, which are environment friendly thereby ensuring a green environment. These PAs are equipped with electronic expansion valve which ensure a far more accurate refrigerant modulation
resulting in high energy efficiency and optimum performance even in very high ambient temperatures. Daikin’s PAs has one of the highest EER (energy efficiency ratio). These are also compactable with various BMS (Building Management System).
VRV system The high ambient VRVIII air-conditioning system is the 7th generation of VRV (Variable Refrigerant Volume) since its launch in 1982. Completely re-engineered to realize opportunities for VRV in taller/larger buildings, it utilizes the latest advances in refrigeration and air-conditioning technology.
Reliability VRVIII is designed and fully tested for an operating temperature range of -5°C to >50°C (in cooling). Reliability is assured throughout, with high specification, worry free design and functions, and Daikin’s proprietary double backup technology ensures constant operation. M.E. was the first to bring this innovative technology to the Sultanate almost a decade ago. Over three years ago M.E. was again the first to introduce VRV systems with environment friendly R-410A refrigerant and with an installed capacity in excess of 25,000TR.
Flexibility Centralized chiller/fan coil systems are generally designed to air-condition an entire building and thereby lack flexibility. VRV systems can be sized to match the precise requirement of a single room, zones and part or complete floor with minimum temperature disruption to either the building as whole or its occupants.
Energy Efficiency The ‘state of the art’ cutting edge inverter technology delivers improved efficiency and performance, while ensuring satisfaction of demands throughout connected zones across the complete operation cycle and low running costs.
Space Saving VRVIII is a sealed, standalone direct expansion system and as such has no need for separate and expensive LPHW circuits, boilers, pumps, fans, water pipes filters, cooling towers and storage tank etc. nor is there any need for dedicated plant rooms and it does not suffer from reduction in efficiency associated with use of secondary energy transfer media such as air and water.

MASCO (Oman Marketing and Services Company) has been operating in the Air Conditioning segment for quite some time. In 1977, the company partnered with Panasonic and have been bringing in unique air conditioning solutions to customers since. According to Kishore Chandrasekharan, Divisional Manager, Air Conditioning and Projects, “Today, in the air conditioning segment, OMASCO and Panasonic are major players in certain segments. In fact, we’re the market leader in unitary decorative splits.”
46

Future Apart from decorative splits, they have been extremely successful in handling medium scale projects for example central AC projects which involve ducting, coordination with false ceilings and the likes. “We have to give credit to a lot of people; OMASCO as a team, because a product does not become successful just because it is good. The team has to be good, the branding has to be strong and in this regard Panasonic has done extremely well, especially with respect to decorative splits.” Chandrasekharan also attributes their success too their sales, design and installation teams – all of which play

a vital role in putting together a project. “You can have a great product, but you also need a great team to be able to put it all together, apply that to the existing market, and coordinate with lots of consultants, engineers, architects, to match their requirements. You need to have systems available that can match their conditions.” And OMASCO has been doing exactly that. Providing customised and turn-key solutions is one of the brand’s strongest suites. Now, having done extremely well in one segment, the company is looking forward to carrying the same momentum into the larger air conditioning segments and will probably venture into the large chilled water segment in the near future. Overall, the air conditioning market has been pretty intensive over the last 10 years. The buildings are becoming bigger and thus, the air conditioning requirements are also changing. So over the last few years, Chandrasekharan affirms, there has been a shift from the predominantly unitary segment to chilled water segment. “In the next few years we will see even bigger buildings, and in turn systems – which means larger engineering teams based out of Oman to execute those products and projects.” The migration of this market is happening and OMASCO is certainly latching on to that. Throughout their journey in Oman, OMASCO and Panasonic have been extremely good in being at the right place at the right time – sometimes even being the industry first in certain segments. “In a very competitive market to be a clear number one is not possible unless you do something different,” explains Chandrasekharan when asked about their strategy. “Not only do you need a good product but you need to innovate those products every year.” 48
DOSSIER – Guide to Air-conditioning & Refrigeration 2012-13
A prime example would be Panasonic’s ‘Intelligent Eco Sensors’ in their ECONAVI air conditioning units. The feature uses high-tech sensors and precise control programmes to optimise appliance performance. The sensors detect room conditions and make appropriate changes to cooling based on the presence of humans and their level of activity and thus, reducing the wastage of energy. “Initially the technology was met with some cynicism but today we sell a sizeable number of ECONAVI products in the market. People want to know about the products and energy savings associated with them. We have managed to create an awareness and in a sense acquired a competitive advantage.” This year Panasonic came out with their Inverter-55 and according to Chandrasekharan, it is probably the best innovation that a manufacturing company has done over the last three decades. “They [Panasonic] brought out a system (an electronic circuit board) that can sustain at 55 degrees C and function at places with desertlike conditions where sand particles can get into the electronic circuit boards. Not only are these systems capable of withstanding and operating in high temperature conditions, but are also energy efficient. “Today people have already started looking seriously into energy savings because over a period of time, if there is no proper planning, Muscat will face a dearth of energy. Unless you have economically viable products which can reduce energy consumption people will find it hard to keep expanding energy resources to meet the growth that is happening. In that sense, the Inverter-55 will bring down electrical infrastructure and will surely change the way people look at air conditioning.”

The development of sustainable building practices often occurs locally with the individual decision of practitioners, owners, code officials and other stakeholders. However, the industry is learning from seeing what others are doing worldwide
S
ustainable design practices differ worldwide. Climate plays one factor in why designs are different, but also variations exist due to factors such as the local acceptable criteria for thermal and humidity control, materials availability, or the ease of connection on-site renewable energy into local grid. However, sustainable building designs have issues or areas in common regardless of where they are built. This article provides an overview of key aspects of sustainable designs in Europe and the Middle East.
Design Practices in Europe Europe, which has climatic condition ranging from Mediterranean sun and warmth to Scandinavian snow and ice, at one time had well-established passive solar designs to provide health and comfort. However, in

the last century it moved to a dependence on mechanically controlled environmental in buildings. Reevaluation and subsequent realisation of what actually constitutes a good quality of life has led to codes of practice such as the Code for Sustainable Homes and BREEAM and are supporting socio-political structures encouraging sustainable design planning. Cities such as Manchester and Liverpool in the United Kingdom helped lead the world into the industrial revolution and are now leading the way into clear sustainable policies.
SUSTAINABILITY IN THE MIDDLE EAST IS FACED BY MANY CHALLENGES, PARTICULARLY THE ABSENCE OF GREEN BENCHMARKING AND REGULATIONS. One example of this leadership in MediaCityUK in Manchester, which is the first “Excellent” environmental development and pilot scheme for the new BREEAM Communities assessment that rates a mixed use development as a whole and its plan to achieving long-term sustainability. During the last century, the UK and the rest of Europe recovered from the rapid developments that had taken place during the industrial revolution, which were underpinned by the use of cheap fossil fuels. Although lifestyles improved significantly, the pace of change lead to inefficient and wasteful, sometimes harmful practices and the lessons learned have led to a better
58
DOSSIER – Guide to Air-conditioning & Refrigeration 2012-13
understanding of what real quality of life is about and why community sharing, health, well-being and socio-economic factors are so important to a happy lifestyle. The considerable financial and human resources previously applied can be better used to achieve sustainability and communities that thrive in friendship and sharing as sustainable designs become the accepted way forward. Wasteful and harmful practices such as power generation from fossil fuels and uranium (which have conversion rates around 35 per cent, meaning that 65 per cent is wasted as heat, and the environment is polluted) are being replaced by district energy schemes that provide power, heat and cooling (via absorption chillers).
Sustainability in the Middle East The share of Middle Eastern countries in sustainability has always been obscured by the perception of them being major fossil fuels exporter. It may be surprising to some to know that the largest LEED platinum building in the world and the Masdar City development (which strives to be the first zero-energy, zero-waste city), are both in the Middle East. However, on a per capita basis, four out of five of the most carbon-dioxideemitting countries in the world are Middle Eastern countries, partly because most of these countries have suffered from a chronic water shortage. Sustainability has always existed in one form or another for a long time in the Middle East. Because of the hot climate, the residents of the region have always tended to keep the hot out of the buildings and save water. This can be seen in the traditional residential architecture and designs that use passive sustainable techniques such as wind
towers, night cooling and shadowing and evaporating cooling. In Abu Dhabi, UAE, one type of traditional residential architectural design known as “Fareej” has many sustainable advantages. It has been recognised by the local residential rating system (Estidama Pearl System for Villas), which could be thought as a local equivalent version of LEED for homes. Having inexpensive and abundant energy sources, many Middle Eastern countries started embracing the importance of sustainability at a late stage compared to other regions of the world. This has happened almost a decade later than the United States, and two decades later than Europe. Energy, especially oil embargos and shortages, was not the stimulus for change in general, although not all Middle Eastern countries are oil producers. Sustainability in the Middle East is faced by many challenges, particularly the absence of green benchmarking and regulations. First, sustainability cannot be achieved without metrics to measure it and gauge its improvement. Until a few years ago, there was no promising green rating system in any of the Middle Eastern countries. The UK and US tried to export versions of BREEAM and LEED. However, they failed to become robust, either due to lack of support from the mother organisation or unsuitability for the local conditions and customs. This situation has changed with the emergence of two promising local rating systems, such as Abu Dhabi’s Estidama Pearl Rating system and the Qatar Sustainability Assessment System (QSAS). The Estidama Pearl Rating System contains specific programmes focussed on communities,
buildings and residential (villas). Second, the absence of regulations in most Middle Eastern countries hampers green design. This applies to regulations in all aspects relating to sustainability including energy codes, air quality acts, water conservation acts, indoor air quality standards, etc. Those involved with green building standards, recognise that sustainable designs know no boundaries. Regional differences in climate and local economies lead to the adoption of practices at differing rates and with emphasis on different topical areas. However, the key purpose of all parties involved should be developing a system that serves members across the globe as well as one that serves to work towards a sustainable planet for us all.

Multiple design, energy and performance considerations go into the development of successful commercial kitchen ventilation systems. Some of these include design air volumes, cross drafts and location and types of makeup air diffusers among many others
I
t is widely reported that effective commercial kitchen ventilation (CKV) systems require what is termed a “balancing act” of multiple elements. The CKV system may be considered a subsystem of the overall building heating, ventilating and air-conditioning (HVAC) system. The physics are simple: air that exits the building (through exhaust hoods and fans) must be replaced with outside air that enters the building (intentionally or otherwise). However, the design considerations aren’t that simple. This article takes a general look at all the factors affecting the performance of CKV systems including design air volumes, cross drafts and location and types of makeup air diffusers. If the replacement air doesn’t come in, that means it doesn’t go out the exhaust hood and problems begin. Not only will the building pressure become too “negative,” the hood may not capture and contain (C&C) cooking effluents due to reduced exhaust flow. There is no piece of equipment that generates more controversy within the food service equipment supply and design community than the exhaust hood in all its styles and makeup air combinations. The idea that by not installing a dedicated makeup air supply, the operator is going to save money (in both first cost and operating cost) is short sighted. It may be okay if, by design, all of the makeup air can be provided through the rooftop HVAC units (this strategy has been adopted successfully by several leading quick-service restaurant chains). However, in full-service and institutional kitchens with
DOSSIER – Guide to Air-conditioning & Refrigeration 2012-13
71
VENTILATION SYSTEMS
Figure 1: Common Exhaust Hood Styles
larger exhaust requirements, it may not be practical (or energy efficient) to supply 100% of the replacement (makeup) air through the building HVAC system. An exhaust fan in the ceiling could easily remove the heat produced by cooking equipment. But mix in smoke, volatile organic compounds, grease particles and vapor from cooking, a means to capture and contain the effluent is needed to avoid health and fire hazards. While an exhaust hood serves that purpose, the key question is always: what is the appropriate exhaust rate? The answer always depends on the type (and use) of the cooking equipment under the hood, the style and geometry of the hood itself, and how the makeup air (conditioned or otherwise) is introduced into the kitchen. The strength of the thermal plume is a major factor in determining the exhaust rate. By their nature, these thermal plumes are very turbulent and different cooking processes have different “surge” characteristics. For example, the plume from hamburger cooking is strongest when flipping the burgers. Ovens and pressure fryers may have very little plume until they are opened to remove food product. Open flame, nonthermostatically controlled appliances, such as underfired broilers and open top ranges, exhibit strong steady plumes. Thermostatically controlled appliances, such as griddles and fryers have weaker plumes that fluctuate in sequence with thermostat cycling (particularly gas-fired equipment). As the plume rises by natural convection, it is captured by the hood and removed by the suction of the exhaust fan. Air in the proximity of the appliances and hood moves in to replace it. This replacement air, which originates as outside air, is referred to as makeup air. The design exhaust rate

72
DOSSIER – Guide to Air-conditioning & Refrigeration 2012-13
VENTILATION SYSTEMS
also depends on the hood style and design features. Wall-mounted canopy hoods, island (single or double) canopy hoods, and proximity (backshelf, pass-over, or eyebrow) hoods all have different capture areas and are mounted at different heights relative to the cooking equipment (see Figure 1). Generally, a single-island canopy hood requires more exhaust than a wall-mounted hood, and a wall-mounted hood requires more exhaust
A FRONT FACE DISCHARGE, WITH LOUVERS OR PERFORATED FACE, CAN PERFORM POORLY IF ITS DESIGN DOES NOT CONSIDER DISCHARGE AIR VELOCITY AND DIRECTION than a proximity hood. The performance of a double-island canopy tends to emulate the performance of two backto-back wall-canopy hoods, although the lack of a physical barrier between the two hood sections makes the configuration more susceptible to cross drafts. Lastly, the layout of the HVAC and MUA distribution points can affect hood performance. These can be sources that disrupt thermal plumes and hinder capture and containment. Location of delivery doors, service doors, pass-through openings and drive-through windows can also be sources of cross drafts. Safety factors are typically applied to the design exhaust rate to compensate for the effect that undesired air
74
DOSSIER – Guide to Air-conditioning & Refrigeration 2012-13
movement within the kitchen has on hood performance. Short-Circuit Supply (Internal Makeup Air): These internal makeup air hoods were developed as a strategy to reduce the amount of conditioned air required by an exhaust system. By introducing a portion of the required makeup air in an untempered condition directly into the exhaust hood reservoir, the net amount of conditioned air exhausted from the kitchen is reduced. Research has shown however, that in the cases tested, internal MUA cannot be introduced at a rate that is more than 15 per cent of the threshold C&C exhaust rate without causing spillage (despite what is shown on the air balance schedule or marketing literature). When short circuit hoods are operated at higher percentages of internal MUA they fail to capture and contain the cooking effluent, often spilling at the back of the hood. Hence it isn’t often recommended. Air Curtain Supply: Introducing MUA through an air curtain is a risky design option and most hood manufacturers recommend limiting the percentage of MUA supplied through an air-curtain to less than 20 per cent of the hood’s exhaust flow. An air curtain (by itself, or in combination with another pathway) is not recommended, unless velocities are kept to a minimum and the designer has access to performance data on the actual air-curtain configuration being specified. It is too easy for the as-installed system to oversupply, creating higher discharge velocities that cause cooking effluent to spill into the kitchen. Front Face Supply: Supplying air through the front face of the hood is a configuration that has been recommended by many
hood manufacturers. However, a front face discharge, with louvers or perforated face, can perform poorly if its design does not consider discharge air velocity and direction. Not all face discharge systems share the same design; internal baffling and/or a double layer of perforated plates improve the uniformity of flow. Face discharge velocities should not exceed 150 fpm and should exit the front face in a horizontal direction. Greater distance between the lower capture edge of the hood and the bottom of the face discharge area may decrease the tendency of the MUA supply to interfere with hood capture and containment. Backwall Supply (Rear Discharge): Lab
testing has shown that the backwall supply can be an effective strategy for introducing MUA. However, the discharge area of the backwall supply should be at least 12 inches below the cooking surfaces of the appliances to prevent the relative high velocity introduction of MUA from interfering with gas burners and pilot lights. As with other local MUA strategies, the quantity of air introduced through the backwall supply should be no more than 60 per cent of the hood’s exhaust flow. Hoods with a deeper plenum or increased diffuser area have lower discharge velocities, allowing higher supply airflows. The back supply plenum may offer the advantage of meeting a “clearance to combustibles” code requirement. It may also be an option to convert a single island canopy into a more functional wallmounted canopy (without actually constructing the wall) as utility distribution can be incorporated within the plenum. If the rear supply utilizes perforated diffusers, it is important that cleanout access be provided (as with any supply diffuser). Perforated Perimeter Supply: Perforated supply plenums (with perforated face diffuser) may be advantageous under some conditions, since the air is directed downward into the hood capture zone. Face discharge velocities should not exceed 150 fpm from any section of the diffuser and the distance to lower edge of the hood should be no less than 18 inches (or the system begins to act like an air curtain). Widening the plenum will lower the discharge velocity DOSSIER – Guide to Air-conditioning & Refrigeration 2012-13
75
VENTILATION SYSTEMS
for a given flow of MUA and reduce the chance of the supply air affecting C&C. If the perforated supply plenum is extended along the sides of the hood as well as the front, the increased area will permit proportionally more MUA to be supplied. Four-Way Ceiling Diffusers: Four-way diffusers located close to kitchen exhaust hoods can have a detrimental effect on hood performance, particularly when the flow through the diffuser approaches its design limit. Air from a diffuser within the vicinity of the hood should not be directed toward the hood. Discharge velocity at the diffuser face should be set at a design value such that the terminal velocity does not exceed 50 fpm at the edge of the hood capture area. It is recommended that only perforated plate ceiling diffusers be used in the vicinity of the hood, and to reduce air velocities from the diffusers at a given supply rate, the more diffusers the better. Displacement Diffusers: Supplying makeup air through displacement diffusers at a good distance away from the hood is an effective strategy for introducing replacement air. It is analogous to low-velocity “transfer air” from the dining room. However, the diffusers require floor or wall space that is usually a premium in the commercial kitchen. A couple of remote displacement diffusers (built into a corner) could help diversify the introduction of makeup air into the kitchen when transfer air is not viable.
Influence of Other Factors on Hood Performance Cross Drafts: Cross drafts have a detrimental effect on all hood/appliance combinations and can adversely affect island canopy hoods more than wall mounted canopy hoods. Cross drafts can also be developed when the
76
DOSSIER – Guide to Air-conditioning & Refrigeration 2012-13
makeup air system is not working correctly, causing air to be pulled from open drivethrough or pass-through windows or doors. Side Panels and Overhang: Side (or end) panels permit a reduced exhaust rate in most cases, as they direct the replacement airflow to the front of the equipment. They are a relatively inexpensive way to improve capture and containment, reduce the total exhaust rate and mitigate the negative effect of cross drafts.
Design Considerations for Energy Savings Hood Style: Wall-mounted canopy hoods function effectively with a lower exhaust flow rate than the single-island hoods. Island canopy hoods are more sensitive to MUA supply and cross drafts than wall mounted canopy hoods. Engineered proximity hoods may exhibit the lowest capture and containment flow rates. Hood Geometry: Interior angles close to, or at, the capture edge of the hood improve C&C performance, allowing reduced exhaust by directing effluent back towards the filters. Hoods designed with these better geometric features require as much as 20% less exhaust rate compared to hoods identical in size and shape without these features. Capture and containment performance may also be enhanced with active “low-flow, high-velocity air jets” along the perimeter of the hood. Variable Speed Fans and Idle Conditions: Using two-speed or variable exhaust flow rates to allow reductions in exhaust (and makeup) while appliances are idling would minimize operating costs.

Planning for the Future
I
World-wide, R22 has been banned due to environmental implications. The phase out has already been implemented however, a complete overhaul of systems are required and that is easier said than done
n 1987 the Montreal Protocol established requirements that began the worldwide phaseout of ozone-depleting CFCs (chlorofluorocarbons). And later, in 1992 the Montreal Protocol was amended to establish a schedule for the phaseout of HCFCs (hydrochlorofluorocarbons). HCFCs are less damaging to the ozone layer than CFCs, but still contain ozone-destroying chlorine. HCFC-22 (also known as R-22) has been
the refrigerant of choice for residential heat pump and air-conditioning systems for more than four decades. Unfortunately for the environment, releases of R-22, such as those from leaks, contribute to ozone depletion. In addition, R-22 is a greenhouse gas and the manufacture of R-22 results in a by-product (HFC-23) that contributes significantly to global warming. As the manufacture of R-22 is phased out over the coming years as part of the agreement to end production of HCFCs, manufacturers of residential air

REFRIGERANTS
conditioning systems are offering equipment that uses ozone-friendly refrigerants. The production and import (not use) of the HCFC refrigerants is being phased out worldwide. This phaseout will repair the ozone layer and reduce incidences of skin cancer and cataracts. Although contractors are not required to stop using HCFC refrigerants nor to replace existing equipment. However, the available supply of R-22 and R-142b will decrease in the future. The phaseout period provides time to switch to ozone-friendly refrigerants when they normally would replace their refrigerant and air-conditioning equipment.
HCFC Phase Out Options Replace whole plant: New plant can be designed to have best energy efficiency, meet current and future cooling requirements and use the latest technology. However, this is the most expensive alternative in terms of cost and has the longest implementation time. Modify plant to use a new refrigerant: This option has a fairly quick implementation time and probably a much lower capital cost than plant replacement. The efficiency might get worse and may not be applicable to all plant designs. There are also some risks of reliability problems. Some plants are not well suited to refrigerant replacement. For example, a large R22 water chiller with a flooded shell and tube evaporator is unsuited to the alternative refrigerants which are blends (e.g. R407C). If, however, the evaporator is a “DX” design (direct expansion) then a blend like R407C might be suitable. Use existing plant with recycled HCFCs: Easy zero capital cost option. Avoids being

an “early mover” – you can benefit from experience gained on other conversions. New technology options could enter the market in next few years. Efficiency not being improved. However, there is no guarantee of recycled HCFCs being available at reasonable cost. Before embarking on a new plant design it is strongly recommended that you do a careful evaluation of cooling loads, to ensure these are properly understood. Cooling loads should be minimised whenever possible (e.g. through use of “free cooling” or through use of variable speed drives on evaporator fans and pumps). Loads at significantly different temperature levels should be cooled by separate refrigeration plants. After you have done a proper cooling load assessment you will be in a good position to specify a plant that gives you the best year round efficiency. Don’t just concentrate on the “design point” (i.e. the peak cooling load in the hottest ambient temperature). The plant will spend much of the time at much lower load and in cooler ambient conditions – good plant design can optimise performance under a wide range of common operating conditions, not just at the design point. You cannot convert to a completely different refrigerant like ammonia – the existing plant will be incompatible with this refrigerant. Your main options will be to use one of three categories of HFC refrigerant, i.e.: • A pure HFC fluid such as R134a. • An HFC blend that is often used in new systems, such as R407C or R404A. • An HFC “Service blend” that has been specifically designed to be retrofilled into an existing R22 plant. A significant issue is that most R22
systems operate with mineral lubricating oil, whilst many HFC refrigerants require polyol ester oil. It is time consuming and costly to change the oil in an existing system – the service blends are designed to avoid or minimise this problem. Another important consideration is the difference between use of a pure fluid or a blend. If your existing R22 plant uses a pure fluid as the refrigerant. This means that evaporation and condensation take place at a constant temperature. Most HFC blends exhibit a characteristic called “temperature glide” – which means that evaporation and condensation takes place across a range of temperature instead of at constant temperature. For some plant designs, a high temperature glide could cause problems and it would be inadvisable to replace the R22 with a new refrigerant blend with a high glide. In general this problem occurs on flooded and pumped circulation systems – which tend to be used on large plants such
as blast freezers, cold stores and large liquid chillers. There is less of a problem with DX (direct expansion) systems – these can cope much better with a refrigerant with a temperature glide. Conversion using a pure HFC refrigerant: This is difficult because none of the pure HFCs have properties close enough to R22. The only realistic alternative is to use HFC R134a. This will require increasing the compressor capacity by about 30%. It may also require different lubricating oil and a number of non-metallic components to be changed (e.g. O-ring seals). To use R134a the plant will require significant modification, which will represent a large financial investment. Conversion using an HFC blend that is often used in new systems: R407C is often used in new systems in place of R22, especially in direct expansion systems. It has properties that are quite similar to R22. DOSSIER – Guide to Air-conditioning & Refrigeration 2012-13

It can also be used to convert an existing system. The use of R407C should require far less modifications than those described above for the use of R134a. However, it will be necessary to convert to a new type of oil and it may be necessary to change some seal materials. Other fluids that fall into this category include R404A and R507. Conversion using an HFC “Service Blend”: A number of refrigerants have been specifically developed to be easily retrofilled into existing R22 systems. As well as having similar thermodynamic properties they also are designed either to require no
AN INTERESTING DEVELOPMENT IN RECENT YEARS HAS BEEN THE RE-EMERGENCE OF CO2 AS A REFRIGERANT oil change or a single oil change. In many situations these blends can be used simply by removing the old refrigerant and refilling with the new one followed by a few simple adjustments to certain controls on the plant. In some situations some components may need replacing (e.g. seal materials). Special care must be taken with flooded systems because of the temperature glide exhibited by these blends. The main options available are Dupont Isceon MO59 (R417A), Forane FX100, RS44 and RS52. Choosing the best option depends on the size of your cooling plant and the way in which refrigerant technology develops over the next few years. If you have a large plant (e.g. a large cold store or freezing facility) then am-
82

monia should be given careful consideration. Ammonia has been a popular refrigerant in the food and drink industry for many years, implying that it is already a cost effective option. In many situations it is possible to design a highly efficient ammonia plant. This will minimise your emissions of greenhouse gases and “future-proof” the plant from possible legislative changes. If you are replacing a relatively small plant, then ammonia can become a rather expensive option, because of the safety precautions required and HFCs would usually be more cost effective. An interesting development in recent years has been the re-emergence of CO2 as a refrigerant. This has been used successfully on a number of food processing and cold storage applications and is definitely worthy of consideration, especially if heat recovery to produce process hot water could be an extra benefit. Using ammonia, CO2 or HCs brings a number of extra practical difficulties that might add to the capital cost of a plant, especially for small systems. While many choices exist when it comes to planning for the R-22 phaseout, no one-sizefits-all solution exists. A careful plan needs to be drafted quickly and put in place as soon as possible, regardless of the size and number of systems being operated. Having no plan – or implementing a plan poorly or too late – may have dire economic consequences when managing the change from R-22 to ODP-free refrigerants. The industry currently has a large number of choices, both from a refrigerants point of view and exit strategies. How the pieces of the puzzle are put together has the potential to significantly impact how the phaseout – and its economics – will affect businesses everywhere.
