摘　　要：随着国内城市轨道交通的快速发展和国家节能减排要求的不断提高,变频热泵轨道车辆空调得到迅速推广应用,取得了良好的节能效果.与此同时,定频轨道车辆空调虽然仍占有一定市场,热泵制热功能能否在定频轨道车辆空调机组上应用仍存在争议.本文通过对轨道车辆空调应用需求、空调机组节流装置限制及空调机组运行可靠性等方面进行分析,认为热泵功能在定频轨道车辆空调中的应用不具有广泛推广的可行性.With the rapid development of urban rail transit in China and the continuousimprovement requirements of national energy conservation and emission reduction,thevariable frequency heat pump rail vehicles air conditioning has been rapidly popularizedand applied and achieved good energy conservation effect.At the same time,although thefixed frequency rail vehicle air conditioning still occupies a certain market,whether theheat pump heating function can be applied in the fixed frequency rail vehicle air condition-ing unit is controversial.Through the analysis of the application demand of air conditioningof rail vehicles,restriction of air conditioning throttle device and air conditioning operationreliability,it is concluded that the application of heat pump function in fixed-frequency railvehicles air conditioning is not feasible to be widely popularized.
