PER of gas enginedriven heat pump systems at different combined supply energy modes

Analyses the thermodynamics principle of high energy efficiency and applying advantages of the gas enginedriven 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.
