Abstract：
Analyses the thermodynamics principle of high energy efficiency and applying advantages of the gas enginedriven heat pump( GEHP) combined cooling heating and power, and discusses the PER of the GEHP at different combined supply energy modes. Simulates the effects on the PER when heat recovery rate, heat pump performance coefficient and the ratio of generating electricity energy to total energy are changed in different seasons, and compares the PER under the different combined supply energy conditions.
Keywords:gas enginedriven heat pump，combined cooling heating and power，PER，heat recovery rate, performance coefficient of heat pump
