分析了热泵型房间空调器室内外侧换热器面积和空气循环量对空调器热冷比以及制冷和制热性能系数的影响。分析结果表明，要提高空调器的热冷比，应适当增加室内侧换热器面积和空气循环量，而减少室外侧换热器面积和空气循环量。
The influences of indoor and outdoor heat exchanger area and air circulation of heat pump room air conditioners on the heat-to-cool ratio of air conditioners and the performance coefficients of refrigeration and heating were analyzed. The analysis results show that, in order to improve the heat-to-cool ratio of the air conditioner, the indoor side heat exchanger area and air circulation amount should be appropriately increased, and the outdoor side heat exchanger area and air circulation amount should be reduced.
