摘要:

对R417A在空气源热泵热水器中的性能与R22进行了对比实验,测试了不同环境温度下采用R417A与R22的COP、功率、冷凝压力和压缩机排气温度等参数的变化。结果表明,在空气源热泵热水器中,R417A的COP与R22比较接近;排气温度比R22低,系统更加安全;冷凝压力也比R22低,说明在同样的冷凝压力下能够得到温度更高的热水;而且更加环保,比R22更加适合在空气源热泵热水器中使用。

Abstract:

Comparison of characteristic between R417A and R22 in the air source heat pump water heater was studied, and the coefficient of performance(COP), power, condensation pressure and exhaust temperature of the compressor on different seasons were tested.The results show that the performance of R417A is closer to that of R22 in the air source heat pump water heater; the exhaust temperature of R417A is lower than that of R22, so the system is more safety; the condensation pressure of R417A is also lower than that of R22, which means that the higher temperature water can be got under the same condensation pressure; and R417A is more environmental protection so it is more befitting for R417A than R22 used in the air source heat pump water heater.
