摘要：

对R22及其7种替代制冷剂的回热循环性能开展了研究。结果显示：R134a、R290、R407C和R507这4种替代制冷剂的回热总是对制冷循环性能有利的；制冷剂R717回热对制冷循环的性能总是有负面影响；随着冷凝温度的升高，回热对制冷剂R22和R410A的单位容积制冷量由不利逐渐变为有利。此外，还进一步讨论了制冷剂R22的7种替代工质采用回热器后性能提高幅度的大小，为在不同场合下选择R22合适的替代工质提供了依据。

Abstract: The vapor-liquid heat regeneration cycles of R22 and seven alternative refrigerants were studied. The results showed that the vapor-liquid heat regeneration was always beneficial to the refrigeration performance of R134a，R290，R407C and R507. Heat regeneration had negative influence on cycle performance of R717 in all calculated conditions. At a higher condensation temperature，the effect of vapor-liquid heat regeneration for R22 and R410A changed from negative to positive. In addition，performance improvement by heat regenerator was discussed for seven alternative refrigerants of R22. This work provides the database for choosing proper alternative refrigerant of R22 in different situations.
