摘要：
A dynamic simulation model is developed for predicting performance of the solar collector/evaporator of direct expansion solar assisted heat pump systems. In this model, the absorber plate temperature is calculated by an ordinary differential equation and the temperature distribution of the refrigerant, Freon-22, is expressed by a partial differential equation. Effects of various meteorological and configuration parameters on performance of the solar collector/evaporator are analyzed. Based on the analyses of the simulation results, the optimum design and excellent working conditions can be proposed for developing the solar collector/evaporator of the direct expansion solar assisted heat pump systems.
