BANGALORE, IndiaA burgeoning middle class, steady eco-nomic growth, booming retail sector, and expansion o services

in health care and IT are pushing India to the top o the leaderboard or air conditioning with annual industry growth trending at20%. No wonder India is capturing the attention o air-conditionermanuacturers and their suppliers. Tapping into this demand arethe major global players. They gathered here or ACREX, the In-dian trade air or air conditioning and rerigeration. An estimated45,000 visitors viewed displays o 500 exhibitors, Feb. 23 25.The inuence o the IT industry was a good example o Indias

powerhouse status in air conditioning. Indian IT is projected tobecome a $225 billion industry by 2020, and IT applicationsrequire sophisticated AC applications.

Rittal, headquartered in Germany, was among companies dis-

playing data center cooling solutions. Its Liquid Cooling Package,the TopTherm LCP inline, received an ACREX innovation award.

The product is designed to sit within a bayed enclosure suite. Hotair is extracted rom the room or warm aisle at the rear o the unit,cooled and then blown out into the cold aisle. The product achievesmaximum perormance and efciency in conjunction with Rittalcold aisle containment. A raised oor is not necessary.

Climaveneta, an Italian-based manuacturer, introduced tothe visitors the concept o Green Data Centre.

Exponential growth in data exchange is increasing the heatload per square meter o all data centers, said Nicola Gardin,the companys area manager. But data centers can still be

green while meeting new standards or improved perormance.

Climaveneta bases its approach on actual data center heat loadrequirements. We match the right confguration with the need,said Gardin. Climaveneta has a hot and cold aisle solution orlow density zones: compartmentalization that prevents hot andcold air rom mixing in the upper section o the racks or me-dium density, and compartmentalization with localized coolingto manage hot spots in high density zones.

Bry-Air, ounded in the U.S., showed its ormed Honeycombmedia or gas phase fltration. According to the company, thedesiccant-based matrix removes ultralow concentrations ogases rom the supply air to control corrosion-causing gaseslike hydrogen sulphide, sulphur dioxide, bromine and oxides onitrogen and chlorine, meeting requirements or data centers,which are oten located near high-density trafc zones, sewerdrains, landflls and process industries emanating such gases.Trane is active in India. The company showcased its chiller

rental, adiabatic cooling services and controls capabilities.Tranes rental chiller is designed to provide immediate or long-term solutions.

To reach out to building owners and acility managers, Tranedisplayed its new adiabatic cooling capability that improvessystem efciency and reliability by decreasing the temperatureo the air entering the coil. Also displayed was the Tracer rangeo controllers or a complete approach to building automation.

Our services and controls capabilities can be applied ina wide variety o acilities, including health care, industrial,lodging, retail and educational buildings, said Rajesh Sikka,

Trane India business leader.Tecumseh Products exhibited its dc compressors, designed

specifcally or battery cooling applications in Indias telecom-munications market.

We see many niche market opportunities in India, said Mike

Noelke, the companys executive vice president or global sales.Roughly 300,000 telecommunication towers are in India,

a number expected to grow to more than 400,000 in the nextfve years. With nearly 60% o their energy consumption romdiesel sets, reductions in energy use can have a major impacton reducing air pollution. Tecumsehs new product, the frst o

its kind manuactured in India and suited or the T3 ambienttemperature range o up to 55C (131F) oten seen in India andthe Middle East, eatures a highly efcient THK reciprocatingcompressor specially ftted with a brushless motor and an ad-ditional controller or converting dc power to three-phase power.

The product has both fxed speed and variable speed capability.These new specialized compressors are afrmation o Tecum-

sehs commitment to provide high quality, efcient products tocustomers in India and the surrounding region, said Jim Connor,company president and CEO. This is just the beginning o ourinitiative to launch innovative and value-added products in theIndian market, said R. Ravi, managing director o Tecumseh

Products India. Our goal is to soon have an expanded oer-ing o high efciency dc solutions or many telecom, solar andmobile applications.

Comort applications are where another U.S. company,EVAPCO, sees growth opportunities or evaporative coolingsystems. Large parts o India have relatively low wet-bulbtemperatures. In other parts o India, evaporative cooling can

be used in combination with conventional systems to deliverhigh quality, cost eective air-conditioning solutions.

We are seeing great demand or our lines o certifed coolingtowers and closed circuit coolers, said Nicholas Torres, salesmanager or EVAPCO Asia/Pacifc. The combination o lowwater usage, low energy consumption, low chemical usage and

lower sound levels is what the Indian market is demanding.Another sector leading the air-conditioning boom is health

care. It is expected to become a $240 billion industry by 2020.Preabricated ducting systems with antimicrobial technologyrom the Italian manuacturer ALP serves that expanding market.

From operating theaters to clean rooms, rom analysis laborato-ries to ood processing rooms, air is responsible or the transport omicrobes, elements o risk or health that cause inections, intoxica-tions, alterations o results, said Vikram Murthy, the companys Indiarepresentative. Air quality in protected rooms is an absolute priority.With greater demand rom IT and health care, we see this in India.According to Murthy, ALP is in the process o setting up qualifed

ALP Ductshops in India. To maintain quality, we need to ensurethere is construction according to the ALP guidelines. Otherwise,we lose our advantage o a high quality solution.

ACREX, held annually, moves to Mumbai in 2013 with de-tails at www.acrex.org.in. ACREX is organized by ISHRAE,a technical society associated with ASHRAE. ASHRAE con-ducted eight Learning Institute courses at ACREX.

VANCOUVER, Wash.A report romthe New Buildings Institute (NBI) identi-fes 99 commercial buildings that are net

zero energy, net zero energy capable orNZEBs under construction. It reports that:

The number and diversity o com-mercial NZEBs are growing, and canbe ound in most climate zones.

The technologies as well as thedesign and construction practices used

to create these buildings are readilyavailable today.

The type o NZEBs are evolvingrom small demonstration buildingsto include K 12 schools, oices, uni-

versity buildings, recreation centers,assembly halls and more. Modeling studies indicate addition-

al costs o 3% to 18% or energy e i-ciency eatures, depending on buildingtype, size, climate and other variables.

The really good news is extremelyenergy e icient buildings are beingdemonstrated in a multitude o climatesand across building types, said DaveHewitt, NBI executive director. Thisis certainly a good sign or the utureo zero energy buildings.The report is available at www.
