空气源热泵以其高效节能、安全环保、使用方便等特点在我国长江流域及以南地区广泛应用,但其在我国北方寒冷地区的推广应用却困难重重。主要是因为在低环境温度下,空气源热泵系统面临着制热能力和制热系数急剧下降、压缩机启动困难、排气温度过高,以及蒸发器频繁结霜等问题。针对这些问题,国内外研究人员对低温空气源热泵技术进行了大量研究。围绕低环温空气源热泵系统、蒸发器除霜技术等方面对现有的研究成果进行总结分析,分析结果对空气源热泵系统在低环温地区的进一步推广应用具有一定的指导意义。

Air-Source Heat Pumps have been widely used in the area of Yangtze River, with the features of its high efficiency, energy saving, safety and environmental protection and easy to use. But troubles in its popularization are obvious in cold regions of northern China. Main reasons includes: when the Air-Source Heat Pump is in a low ambient temperature, its heating performance and COP are at a very low level, the compressor is difficult to start, the compressor shuts down to protect itself because of the high exhaust temperature, and the evaporator frosts frequently in high humidity areas. Faced with these problems, domestic and foreign researchers have done a lot of researches on the low ambient temperature heat pump technology. This paper mainly introduces and analyzes new technologies of ASHP system and evaporator frosting. The analysis has directive significance for spreading ASHP in low ambient temperature areas.
