| 摘要: |
| 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。 |

| Abstract: |
| 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 experiment 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 well applicability using in heat pump water heater. This research provides the references for the refrigerant selection of the heat pump water heater. |
