R22和R417A应用于空气源热泵热水器的性能对比研究

【中文摘要】 在不同的环境温度下,对R417A在空气源热泵热水器应用中的性能特性和R22进行对比实验。结果表明:R417A可以直接替代R22在热泵热水器中使用。应用R417A替代R22,可以明显地降低排气温度和排气压力,有利于系统安全运行,提高压缩机的使用寿命。但是,在直接替代条件下,R417A制热性能系数(HCOP)比R22小。

【英文摘要】 Comparison of characteristics between R417A and R22 in the air source heat pump water hearter(HPWH) were texted.The results indicate that:R417A can substitute for R22 in HPWH directly.The discharge temperature and the discharge pressure decreased obviously with using R417A,it is benefit for the safety operation of the system and raising the service life of compressor.However,with the lower consumption power and much lower heat capacity,the heat coefficient of performance(HCOP) of the HPWH using R417A is smaller than using R22.
