空调和制冷毕业论文 中文资料外文翻译文献 India HVACR Goes Global The total market size in 2008 for the HVACR 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 HVACR 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 dioxid
