摘要
介绍了带有喷射器增压节能装置的制冷系统的概念及特点,并对双效型空调压缩喷射系统进行了理论热力计算和仿真模拟研究,比较了带喷射器的制冷系统与传统简单制冷循环系统的性能系数以及耗电量,对比分析得出较明显的节能效果。模拟结果表明:在制冷系统中引入喷射器增压节能装置,其制冷效率可以得到一定程度的提高,预期可降低整机耗电量4%～12%。
This paper introduces the concepts and characteristics of refrigeration system with thermo-jet boosting and energy saving device. According to various connection mode, compared with the traditional simple refrigeration systems on perform- ance coefficient and power consumption through thermodynamic calculation, simulation research, the air-condition system with ejector gets an ideal energy saving effect. The simulation results show that the coohng efficiency of the refrigeration sys- tem with boosting energy saving device can get a degree of improving, and the expected power consumption can reduce by 4% - 12%.
