摘 要 ：太阳能热泵供热系统中热泵和集热器的结合方式对其性能有较大影响。对热泵在前、集热器在后的热泵串联太阳能供热系统（HP+SC）与集热器在前、热泵在后的太阳能串联热泵供热系统（SC+HP）进行对比研究。以南京地区气候条件为例，设计出供热能力为10kW的太阳能热泵供热系统，建立其系统数学模型，深入分析两种结合方式下的热泵系统性能。结果表明：在典型晴天，随着太阳辐射强度的增大，热泵串联太阳能供热系统中热泵的性能优于太阳能串联热泵供热系统，热泵串联太阳能系统中的热泵COP最大可提高6.65%。 关键词 ：太阳能 热泵 供热系统 性能 Numerical Simulation And Comparation On The Performance Of Two Series Solar Assisted Heat Pump Systems Zhu Xia Liang Caihua Zhang Xiaosong School of Energy and Environment, Southeast University, Nanjing Jiangsu 210096, China Abstract: Two series systems with the different relativity position of heat pump and solar collect are presented in this paper. Through simulation, performance coefficient and operation law of the heat pump with collector system (HP+SC) and the collector with heat pump system(SC+HP) be compared in the paper. Mathematical model is built based on the meteorological date and the 10kW air-source heat pump. From the results of the simulation, the heat pump in the HP+SC system have a better performance than that in the SC+HP system with the increase of the radiation from the sun . The COP of the heat pump in the heat pump with collector system is 6.65% more than that in the collector with heat pump system at most.
