Combined cooling heating and power (CCHP) systems based on natural gas is widely applied abroad, which have resulted in increasing domestic attention to distributed energy systems (DES). In order to reduce heat loss of exhaust-gas and recover condensation heat of it, an innovative system is advanced by Tsinghua, which can recover exhaust-gas condensation heat utilizing an exhaust-gas-driven absorption heat pump (AHP). In 2007, Tsinghua bears a research task from National Ministry of Science and Technology, that is, ‘Integration and Demonstration study of high-efficiency natural gas CCHP technique’. As a part, a natural gas CCHP system based on AHP has been set up at the Tsinghua University energy-saving building, in Beijing, China, and a lot of research has been made. As another part, a combined cooling heating and power (CCHP) project based on the gas-powered internal combustion engine (ICE) (electricity volume MW) is built in Beijing Southern Station. This paper mainly analyzes and introduces the running condition of this demonstration project.
