As an energy-saving and environmentally friendly technology, the combined cooling heating and power system (CCHP) had been applied in the field of heating and air conditioning. Chinese researchers recently designed a CCHP system with the condensation heat recovery of the flue gas, which composed of a gas-powered internal combustion engine (ICE), an exhaust-gas-driven absorption heat pump (AHP), a flue gas condensation heat exchanger (CHE), and other assistant facilities, such as pumps, fans, and end user devices. The system was built and operated in 2011. We tested the parameters of the system on the heating and cooling status from the ICE to the CHE, including the temperature and flux of water, the inlet and outlet parameters of different facilities, and the performance of different facilities for a typical operation status. Based on the test results, the overall COP of the system in the heating and cooling mode was computed, and the energy efficiency level was analyzed. The results indicated that the energy utilization efficiency is about 94% on the heating status, and the energy utilization efficiency is about 84% on the cooling status. These results could serve as a reference for designing or evaluating the CCHP systems.
