摘　　要：本文基于混合动力燃气热泵系统,设计了该系统的并联式驱动形式。基于发动机燃气消耗率以及发动机与压缩机的速度匹配,对并联式驱动系统的传动装置进行了设计。对余热回收系统的管道布置方式进行了区分和研究,选择了旁通式的余热回收系统。将并联式驱动系统、余热回收系统以及热泵系统结合构建了并联式混合动力燃气热泵系统。在此基础上,对该热泵系统进行了电机恒定扭矩的充放电试验,研究了在不用运行模式下,整个系统的性能与各个参数的变化规律,包括:热泵性能系数(COP)、热泵制热量、发动机燃气流量、余热回收量。最后,基于对系统的试验性能研究,分析该系统的一次能源效率(PER)的变化规律,并与燃气热泵系统进行比较。结果发现,电机充电扭矩提高系统PER约14%效果明显,而电机扭矩提高系统PER为1.1%左右。The parallel-type drive system has been designed based on the hybrid power gas engine heat pump. In addition, the transmission value of gearing box can be established by the relationship between gas engine and compressor. The bypass-type heat recovery system is applied in this system. So the parallel-type hybrid power gas engine heat pump can be built on the foundation of drive system, heat recovery system and heat pump system. Then the charge-discharge performance study of this system can be obtained by the study of system performance and the change rules of different parameters, including coefficient of performance （COP）, the heating capacity, heat recovery capacity, gas quantity. At last, the change rules of primary energy rate （PER） of this system has been compared with the gas engine heat pump. The results show that, the charge-discharge torque is useful to improve the PER. In the way of charge condition, PER can be improved by 14%; In the way of discharge condition, PER can be improved by 1.1%.
