Abstract | A thermodynamic model of high temperature heat pump steam system was developed,in which four preliminary screening pure working fluids R123,R141 b,R245ca,R245 fa as well as traditional medium-high temperature working fluid R114 were used to conduct a comp |
Other Abstract | 建立了高温热泵蒸汽系统的热力学模型。在蒸发温度为60℃,冷凝温度为120~140℃的工况下,进行经过初步筛选的4种高温热泵纯工质(R123,R141b,R245ca,R245fa)和传统高温热泵工质(R114)的循环性能对比研究。结果表明:R245fa的综合循环性能良好,单位容积制热量最高,其性能系数(COP)比R114平均高13.65%,压缩比与R114最接近;在符合干压缩要求的前提下,排气温度较低,而且环境友好,可作为高温热泵蒸汽系统的工质。 |
