对新替代品R410a、R410b和R507以及混合物R32/R125/R143a/R134a的流体流动传热特性进行了对比研究。在稳态条件下，使用由8kW容量的热泵组成的实验装置，获得了强化表面管内的传热特性数据。结果表明，与混合制冷剂和R-22相比，R507的传热速率最低。R507显示出比制冷剂混合物（包括R-22）更高的压降。关键词:1997年，制冷剂，比较，混合物，R22，R410a，R410b，R507，热泵，热流，传热流体引用:研讨会，ASHRAE Trans。1997年，第103卷，第一部分

Presents a comparative study of fluid flow heat transfer characteristics of new alternatives R410a, R410b and R507 and the mixture R32/R125/R143a/R134a. States the data on heat transfer characteristics were obtained inside enhanced-surface tubing using an experimental setup composed of a heat pump with 8kW capacity under steady state conditions. States the results show that R507 has the lowest heat transfer rate compared to the refrigerant blends and R-22. R507 exhibited a higher pressure drop than the refrigerant mixtures, including R-22.KEYWORDS: year 1997, Refrigerants, comparing, mixtures, R22, R410a, R410b, R507, heat pumps, heat flow, heat transfer fluids
