A4-02 United states department of energy absorpton heat pump and chiller program- R.DeVault (USA)

The U.S. Department of Energy (DOE) is working with partners from the gas heating and cooling industry and the power generation industry to improve energy efficiency using advanced absorption technologies, to eliminate chlorofluorocarbons and hydrochlorofluorocarbons, to reduce global warming through more efficient use of primary energy, and to reduce electric peak demand resulting from air conditioning loads. To assist industry in developing these gas heating and cooling absorption technologies, DOE sponsors the Thermally Activated Technologies Program. Key activities include ammonia-based residential and light commercial gas absorption heat pumps and chillers, advanced “hi-cool” heat pump technology, water-based large commercial chillers, and integrated energy systems that match heat driven absorption technology with power generation. Opportunities for further advancements in absorption technologies exist, particularly for expanding integration of energy systems through combined heating, cooling, and power applications achieving energy efficiency approaching 80%.
