Résumé

The aim of this study was to understand the performance of a solar ejector cooling system in the Zhengzhou region, and to establish a simulation program of the solar ejection system performance. By combining the climate conditions in the Zhengzhou region, research on the hourly performance of the solar ejector cooling system under different generator temperature, condenser temperature and evaporator temperature, the authors analysed the COP(o) of the solar ejector cooling system. It is found that COP(o) of ejector system increases with the increasing of generator temperatures and evaporator temperature and decreases with the increasing of condenser temperature. Calculation of the COP shows that the system COP(o) increases first and then declines by the time sequence, and the biggest COP(o) of system can reach 0.35 when the evacuated tube collector area equals 20 square metres and the villa area equals 200 square metres, it is determined that the solar ejector cooling system can supply 66 percent cooling load for the villa during the hours 8:00-17:00 in the Zhengzhou region.
