摘要
为了确定发生温度对太阳能喷射式制冷系统性能的影响,基于太阳能喷射式制冷系统试验台,以蒸发温度、冷凝温度及室内环境温度为定量,发生温度为变量进行了试验研究.试验结果表明:当喷射器结构确定时,喷射系数ER、系统性能系数COP和机械性能系数COP_m均不会随着发生温度的升高一直增大,系统必然存在一个最佳的发生温度使其性能达到最佳.研究可为今后最佳发生温度的选择及实际应用中如何维持系统高效运行提供理论指导.
In order to study the effect of generating temperature on the solar ejector refrigeration system,a series of experiments were carried out in a solar ejector refrigeration system,in which the evaporating temperature,condensing temperature,and the indoor environment temperature were constant,and the generating temperature was variable.The results indicated that at a given ejector structure,the ejection coefficient ER,system performance coefficient COP,and mechanical COPm would not always increase with rising generating temperature.Therefore,an optimal generating temperature existed,at which the best system performance can be achieved.The study provided the guidance for choosing optimal generating temperature in the future and maintaining the high efficiency operation of the system.
