摘要:
讨论了一种新型的制冷装置——热管喷射式制冷.描述了其工作原理,讨论了关于喷射系数和系统性能系数COP的计算方法,分别采用R22和水为制冷工质,进行多次计算取得最大喷射系数,并对系统性能系数COP作了定量的计算.分析计算结果得出喷射系数和COP随蒸发温度和发生温度的升高而增大、随冷凝温度的升高而减小,同时得到R22为制冷工质的系统性能系数COP在te=10?℃,tc=35?℃和tg=80?℃时可达0.38, 明显优于水为工质的系统.结果表明该系统有广阔的运用前景,尤其在太阳能利用领域.
Abstract:
A combined refrigeration system—heat pipe/ejector cooler was studied theoretically. The cooling mechanism and some basic characteristics of the system, such as entrainment ratio, coefficient of performance(COP)were analyzed.These system characteristics in use of R22 and water respectively as a working fluid were calculated.It is found that the entrainment ratio and COP will increase with the increasing of evaporator temperature and generator temperature and the decreasing of condenser temperature. As a working fluid, R22 is shown in the present study to be better than water. The measured COP for the system used in the present study can reach as high as 0.38 at te=10 ℃,tc=35 ℃ and tg=80 ℃. The results show that this new refrigeration system can be widely used in many areas, especially in solar energy utilization.
