提升热泵型变频空调器APF技术途径的试验研究

摘要

Through the weight analysis on each variable of affecting APF (annual performance factor) for heat pump frequency-conversion air conditioner,the technical approaches of APF promotion is put forward and the corresponding experimental study is carried out.The results show that the effective technical approaches of APF promotion for heat pump frequency-conversion air conditioner include rational design of the heat exchanger flow path,enlarging the heat transfer area,using the heat exchanger with small diameter,reasonably determining the air volume of indoor and outdoor fans and optimizing the frequency of compressor,etc..%通过对影响热泵型变频空调器APF各变量的权重分析,提出提升APF的技术途径,并进行试验研究.结果表明,合理设计换热器流程流路、增加换热面积、采用小管径换热器、合理确定室内外风机风量,以及优化压缩机频率等是提升热泵型变频空调器APF的有效技术途径.
