STUDY ON SOLAR ENERGY EJECTOR REFRIGERATION SYSTEM COUPLED WITH DIRECT EVAPORATION

为充分利用地区气候优势,提高太阳能利用率,提出一种以R134a为制冷工质的太阳能喷射与直接蒸发耦合新型制冷系统。通过对比分析并对该系统最佳发生温度进行研究,得出在新疆喀什地区典型年气象条件下,新型制冷系统、常规电压缩制冷系统及传统太阳能喷射制冷系统的一次能耗对比。结果表明,太阳能喷射与直接蒸发耦合制冷系统比传统太阳能喷射制冷节能24%,比常规电压缩制冷系统节能97%。

In order to make full use of advantages of regional climate, and improve the utilization rate of solar energy, a kind of solar energy ejector refrigeration system coupled with direct evaporation is put forward. Its thermodynamic analysis is and furthermore, the best generating temperature of the coupled system using solar energy ejector refrigeration on a certain condition is studied through experiments. On the typical meteorological conditions in Kashgar, Xinjiang, the primary energy consumption of R134a coupled system is compared with that of conventional electric compression refrigeration system and traditional solar energy ejector refrigeration system. The results show that the R134a coupled system is 97% energy-saving than the former, and 24% energy-saving than the latter.
