Discussion the exergy utilization efficiency on GEHP system of the CHCP

Based on analyzing the exergy utilization efficiency of gas engine-driven heat pump (GEHP) system, the simulation calculation results of the exergy utilization efficiency on different combined heating, cooling and electricity (CHCP) conditions were given. Set up the concept of heat exergy recollection ratio and discussed the influence of heat recollection ratio and heat recollection temperature It gives that the exergy utilization efficiency of GEHP system with heat recollected is better than no heat recollected at operational models, the exergy utilization efficiency increases as exergy utilization efficiency and the rules of heat recollection ratio and heat recollection temperature to exergy utilization efficiency of CHCP system were provided. It shown that the heat recover plays the important action for increases exergy utilization efficiency of GEHP system.
