空气源热泵机组融霜性能研究现状

Development status of research on frosting,anti-frosting and defrosting of air source heat pump units

通过分析国内外专家学者对于空气源热泵机组结霜、抑霜和除霜的研究成果,归纳结霜机理,总结抑霜和除霜技术的特点,分析认为,数学模型分析与实验结果存在差异;针对换热盘管建模和实验较少;现有研究未能从根本上解决空气源热泵机组除霜的问题,有待进一步开展相关技术和设备应用研究。

By analyzing the research results of frosting,anti-frosting and defrosting of air source heat pump units of experts and scholars at home and abroad,induce the mechanism of frosting and summarize the characteristics of anti-frosting and defrosting technology. The analysis shows that there are differences between mathematical model analysis and experimental results. The modeling and experiment for heat exchange coil are less.The existing researches have not fundamentally solved the defrosting problem of air source heat pump units and needs further research on related technologies and equipment application.
