空调设计外文翻译---印度暖通空调与冰箱工业走向世界

India HVAC&R Goes Global

The total market size in 2008 for the HVAC&R industry in India was approximately $2.5 billion. That year, India produced roughly 5 million refrigerators, 2.5 million room air conditioners, packaged air conditioners of various capacities, and packaged chillers of reciprocating, scroll, screw and absorption types.

Other HVAC&R products manufactured in India include air-handling units, fan-coil units, refrigeration systems for cold rooms and freezer rooms; low-temperature brine chillers for industry; and commercial refrigeration equipment for food stores and supermarkets. The following stories describe some Indian companies that are making their mark internationally.

Heat Pumps in Denmark

Thermax absorption heat pumps and chillers are finding increasing acceptance with European and U.S. clients that want energy-efficient equipment. Businesses are demanding systems that can reduce carbon emissions and help cope with global warming.

Over the last decade, Thermax has worked in optimizing energy use in Denmark by installing absorption heat pumps for centralized heating, which is a reverse application of centralized cooling with absorption chillers. Hot water from a central generation facility is used for space heating in town buildings. The heating companies reduce the energy intensity at generating centers by tapping low-grade heat from other sources such as geothermal heat from sandstone aquifers or waste heat from town incinerators.

Since its first installation in 1999, Thermax absorption heat pumps are operating in several district heating installations. Recently, the company is fulfilling an order for a 3.4 MW steam absorption chiller to be installed in downtown Copenhagen as part of a district cooling project. The total capacity of the plant is 15 MW, which uses the output of the Thermax chiller, free cooling using seawater and ammonia chillers. The plant will save approximately 2,500 tons (2268 Mg) of carbon dioxide per year.

In Spain, Thermax has commissioned chillers in hotels and office buildings that run on water heated by solar panels. Clients elsewhere in Europe also use Thermax chillers that work on exhaust gas from fuel cells or excess steam from old boilers that use wood waste.

In the United Kingdom, large retailer Tesco has installed Thermax chillers at two

stores as part of a plan to reduce its carbon footprint through various measures, including using energy-saving devices. The chillers use water from the cogeneration system that Tesco has installed for generating power.

In the United States, a 1,100 kW test engine installed at a plant of a leading plastics manufacturer in Ohio generated a great deal of waste heat. Thermax harnessed this waste heat to drive an absorption chiller. Waste heat is converted to energy savings as chilled water from this system is used for process cooling in the plant. More than 150 business customers in the United States are gaining from energy profits and green reputations by installing Thermax chillers. Recently, the University at Albany-State University of New York，replaced its old, inefficient cooling system with a 1,400 ton (4924 kW) chiller that works on hot water. The university has gained 35% energy efficiency with substantial savings in operating and maintenance costs. The Henry Ford Museum in Detroit and Colorado School of Mines in Golden, Colo., also have Thermax chillers.

Under a recent strategic agreement, Trane, a leading global indoor comfort systems and service provider for the North American market, will source and distribute Thermax chillers.

Heat Wheels in Australia

What do a hospital in Australia, a university in Florida, a high-tech commercial building in Dubai, a church in Brazil, the Olympic stadium and airport in Beijing and an indoor swimming pool in Tasmania have in common? The indoor air quality provided by DRI, Desiccant Rotors International, is a heat wheel manufacturer in Delhi. A flagship company of the Pahwa Enterprises, it is the largest privately held HVAC group in India.

King Edward Memorial Hospital (KEM) in Perth, Australia, is a renowned, state-owned health-care provider for women,with more than 400 beds and a large staff of specialists. KEM is geared to provide the highest standards of health care and patient servicing, where indoor air quality plays a vital role. The original HVAC installation carried out 30 years ago was ahead of its time. It incorporated heat recovery wheels (HRW) to save energy and provide better indoor air quality. The wheels were imported from the United States and the aluminum substrate was supplied in 20 segments. With the passage of time, the substrate disintegrated and fell off in all four wheels. As a result, the wheels became non-operational and KEM Hospital and the authorities had a tough time finding a supplier that could supply new
