To improve the efficiency of space heating and cooling
the hybrid power-driven heat pump (HPHP) has been established. However
both the design method and operation strategy are too simplified
thus optimization is needed. In this paper
the HPHP with a gas engine and motor is put forward
and a mathematic model of HPHP is established to analyze its operation performance under a typical design (i.e.
the gas engine takes 60% of the torque output under the design condition). The operation performance of the HPHP is also compared with gas engine-driven heat pump(GEHP)and electrical heat pump (EHP). The results show that the HPHP system can achieve 3-10% improvement of engine efficiency compared to the GEHP. The primary energy ratio (PER) of the optimized system is 6.9% and 5.4% higher than that of GEHP and EHP
as the ambient temperature is﹣5 ℃. The HPHP system can achieve higher energy saving potential for the whole heating season.
