空气源热泵除霜技术进展与区域化应用综述

Summary of the Air Source Heat Pump Defrosting Technology and Regional Application

空气源热泵在冬季制热效果受到结霜等问题的影响,引起学者们的广泛关注。其中改进除霜技术可以极大的提升空气源热泵在冬季的制热性能。在整合中外针对除霜技术研究进展后,明确了除霜研究方法主要有数学模型研究和试验研究两大类型,发现了多模式除霜技术作为突破常规除霜方法瓶颈的手段,成为当下研究热点。分析总结认为,在应用层面,恰当评价体系可以提升不同技术在不同区域的除霜性能,提出了“抑霜为先,除霜为后”的技术原则,以期为空气源热泵技术大规模推广和应用提供参考。

The heating effect of air-source heat pump in winter is affected by frost and other issues,which has attracted the attention of many scholars.The improved defrosting technology can greatly improve the heating performance of the air source heat pump in winter.After studying the domestic and foreign research progress on defrosting technology,it is clear that there are two major types of defrosting method research of mathematical model research and experimental research.The multi-mode defrosting technology was found as a means to break through the bottleneck of conventional defrosting methods and became the current research hot spot.A proper evaluation system in application could improve the defrost performance of different technologies in different regions.The technical principle of“stop frosting first,defrosting later”was proposed to promoting the large-scale promotion of air source heat pump technology.
