非标工况下毛细管长度对家用空调器性能影响规律的研究

摘要

通过研究家用空调器的制冷量、能效比、排气温度、吸气温度等随室外温度和毛细管长度的变化规律,得出增加毛细管长度有利于提升高温工况下的制冷量,缩短毛细管长度有利于提升低温工况下的制冷量的结论,对于空调系统匹配有一定的指导意义.%The influence law of capillary length and outdoor temperature on cooling capacity, COP, exhaust temperature, suction temperature of room air conditioner are analyzed. The results show that increasing capillary length is benefit for cooling capacity under high temperature condition and decreasing length brings advantage to cooling capacity under low temperature condition. The study will provide reference for air-conditioning system matching.
