1、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 reciprocatin
2、g, 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.
3、 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 t
4、hat 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
5、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 instal
6、lation 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 1
7、5 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
8、. 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 var
9、ious 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.
10、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 insta
11、lling 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 cost
12、s. 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 Whee

14、ional, 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 sta
15、ff 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 be
16、tter 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
17、had a tough time finding a supplier that could supply new wheels in sections that could pass through the doorways without breaking down the walls of the AHU room. They also had difficulty finding an installer who could dismantle the old steel frames, also in sections, so the building could remain in
18、tact. Fortunately, DRI, through its Australian agent agreed to custom manufacture a five-segment wheel in its factory, ship it to the site, install and commission the new wheel, all under the supervision of a local consultant. With the completion of the retrofit project, KEM Hospitals indoor air qua
19、lity improved. Among other projects DRI has done are the Beijing Olympics； Pacific Controls, which is Dubais first green building； and the second tallest building in China, which is the 450 m (1,476 ft) tall Nanjing Green Land Square, which are all equipped with Ecofresh wheels produced in Delhi.

Heat Pumps in Europe Blue Star began exporting drinking water coolers to the Gulf countries in the Middle East as early as 1974.
22、 The large stainless steel storage tank design of the coolers was suitable for India and the Gulf countries where city water supply was intermittent. Although local buyers initially resisted buying Blue Star coolers, with improved quality and timely deliveries the companys sky-blue water coolers bec

In the early 1990s, Blue Star made large investments in new plant, machinery, technology and R&D for HVAC&R products to handle the growing market within the country. In 1999, the company started exporting ducted air conditioners of up to 7.
24、5 ton (26 kW) capacity, as well as window and split room ACs. A substantial part of these products were specially designed for an American company； prototypes were built and tested in India and the U.S., to suit the needs of the U.S. manufacturer for the Middle East market.
