60℃水冷自复叠制冷系统研究

提出一种新型水冷自复叠制冷循环方式,用冷凝分离器代替传统循环的冷凝器和相分离器,在冷凝分离器中同时完成了高沸点工质的冷凝及高沸点工质与低沸点工质的分离。对采用这种冷凝分离器的水冷自复叠制冷循环方式的R22/R23、R290/R170、R134a/R23、R134a/R170四种工质对进行了循环特性研究。在自行搭建的水冷自复叠制冷系统实验台上进行了R22/R23、R134a/R23两种工质对的实验研究。结果表明,在相同工况下,R22/R23自复叠制冷系统的COP要高于R134a/R23自复叠制冷系统;和传统的自复叠系统相比,采用冷凝分离器的水冷自复叠制冷循环COP明显提高,提升率达到60%-10...

Summary:提出一种新型水冷自复叠制冷循环方式,用冷凝分离器代替传统循环的冷凝器和相分离器,在冷凝分离器中同时完成了高沸点工质的冷凝及高沸点工质与低沸点工质的分离。对采用这种冷凝分离器的水冷自复叠制冷循环方式的R22/R23、R290/R170、R134a/R23、R134a/R170四种工质对进行了循环特性研究。在自行搭建的水冷自复叠制冷系统实验台上进行了R22/R23、R134a/R23两种工质对的实验研究。结果表明,在相同工况下,R22/R23自复叠制冷系统的COP要高于R134a/R23自复叠制冷系统;和传统的自复叠系统相比,采用冷凝分离器的水冷自复叠制冷循环COP明显提高,提升率达到60%-100%。

A new water-cooled auto-cascade refrigeration cycle（ WACR） using a binary refrigerant mixture is presented,which adopts a condenser-phase separator instead of a condenser and an evaporative separator in traditional auto-cascade refrigeration cycle. In condenserphase separator,high boiling point refrigerant can be condensed,and high boiling point and low boiling point refrigerants can be separated. Characteristics of four binary refrigerant mixtures（ R22 / R23,R290 / R170,R134 a / R23,and R134 a / R170） circulation were analyzed. And the WACR using R22 / R23 and R134 a / R23 were studied experimentally. In the same condition,the COP of WACR using R22 / R23 is higher than that of the WACR system using R134 a / R23. Compared with the traditional system,COP of the new water-cooled auto-cascade refrigeration cycle（ WACR） is higher from 60% to 100%.
