首先从热物性、ODP、GWP、工质毒性、可燃性方面对HFO-1234ze、R417A、R22三种制冷剂进行对比,并进行理论计算,初步分析HFO-1234ze制冷剂运用在空气源热泵热水器上的可行性.然后,在焓差法实验室内,对分别采用HFO-1234ze,R417A和R22作为制冷工质的空气源热泵热水器进行名义工况下的性能测试,对三种制冷剂的吸排气温度,吸排气压力,压缩机输入功率、制热量、性能系数进行对比分析.本文研究结果显示HFO-1234ze可以作为R417a与R22在热泵热水器中的替代制冷剂.此次研究为热泵热水器的工质选择提供参考.
Research on HFO-1234ze Replacing R417A and R22 Used in HPWH
HFO-1234ze,R22 and R417A were compared with each other from aspect of thermal properties,ODP,GWP,toxicity,flammability and so on.Theoretical feasibility of HFO-1234ze used in heat pump water heater was analyzed through theoretical calculation.A test is carried out on the air resource heat pump water heater using HFO-1234ze,R22,and R417a under standard conditions.Suction and discharge pressure,suction and discharge temperature,compressor input power,thermal heating capacity,and coefficient of performance had been analyzed.The result shows that HFO-1234ze has good applicability using in heat pump water heater.This research provides the references for the refrigerant selection of the heat pump water heater.
