Finally, we can not use electric power but the engine of bus or subsidiary engine to drive air compressors of bus air conditions. because the change range of turnaround speed of engine is very wide, that brings difficulties in controlling the rate of flow of cold - producing medium. in the control of bus air - conditions, preventing evaporator from freezing to make the air - conditions work with high efficiency and controlling the temperature of railway carriage are the basic tasks in air - condition control
與一般的建築空調相比，汽車空調的工作環境惡劣，條件差，控制難度要增加很多，主要體現在以下幾個方面：一是車外熱負荷變化大，難以確定控制參數；二是要求空調負荷大，而且要控制空調使其降溫迅速：三，不便於用電力作為動力源，必須用汽車發動機或輔助發動機來帶動壓縮機，當採用汽車發動機作為動力源時，由於汽車的車速變化大，發動機轉速的變化可從600r min到4000r min ，壓縮機轉速與發動機轉速成正比，其轉速變化高達7倍，給空調系統製冷劑流量控制帶來困難。 -
