摘要
R32作为R22的主要替代品之一,具有良好的热物性。R32管内流动传热特性的研究对R32换热器的设计具有重要意义。目前针对R32管内流动传热特性的研究还存在不足。本文调研了已发表的R32管内流动传热研究数据,分析了R32管内流动传热特性,特别对R32管内流动换热经验关联式进行了说明,指出了R32管内流动传热研究的不足和研究方向。R32管内流动传热特性的研究为R32换热器的设计提供了指导,对R32替代技术的起着推动作用。
As one of the main R22 alternatives,R32 has good thermal properties.It is a great significance of R32 refrigerant-side flow and heat transfer characteristics for R32 heat exchanger design.At present,study of R32 refrigerant-side flow and heat transfer characteristics is still insufficient.R32 refrigerant-side research data is studied,and R32 refrigerant-side flow and heat transfer characteristics is analyzed,R32 refrigerant-side flow and heat transfer empirical correlations are compared and described especially.At last,R32 refrigerant-side research directions are pointed out.R32 refrigerant-side flow and heat transfer characteristics provides guidance for R32 heat exchanger design,and plays an important role in promoting R32 alternative technologies.
