摘　　要：从制冷系统热动力学的理论出发,对太阳能热泵PV蒸发器建立了相应的二维模型,并对太阳辐射强度、环境温度以及结构参数等对运行状况的影响进行了数值模拟研究。结果表明,该模型能有效的预测蒸发器内的运行工况,也可作为部件及系统优化设计的依据。From the theory of thermodynamics of refrigeration system, a two-dimension model for the evaporator of solar assisted heat pump was setup. Based on distributed parameters, the numerical simulation of the influence of radiation intensity, ambient temperature and model parameters on operating conditions was studied. The results indicate that the model is an effective way to predict the operating targets in evaporator and it also provide basis for component and system optinral design.
