| Abstract: | Recent years, energy consumed by air-conditioning system increases sharply and becomes a large part of the energy consumed in buildings. This article primarily introduces the new energy-saving technologies used in air-conditioning system, including the developing and application of frequency conversion technology, the potential application of solar energy driven refrigeration, the application of ground source heat pump, researches on new heat storage technology, and the technology of distributed CCHP （combined cooling, heating and power） system. |
