文章研究了水、甲醇等6种工质在热管喷射式制冷循环中的工作特性。计算结果表明,工质的冷凝温度对系统COP的影响比较大,在发生温度一定的情况下,较低的冷凝温度和较高的蒸发温度能有效提高系统的COP,在各种运行条件下,甲醇、R11、R123等工质有较高的COP。
In this paper, the working characteristics of six kinds of working mediums, such as water and methanol, in the heat pipe jet refrigeration cycle are studied. The calculation results show that the condensing temperature of the working fluid has a great influence on the COP of the system. When the temperature is constant, the lower condensing temperature and the higher evaporating temperature can effectively increase the COP of the system. Under various operating conditions, Methanol, R11, R123 and other refrigerants have a higher COP.
