| 10. | 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
与一般的建筑空调相比，汽车空调的工作环境恶劣，条件差，控制难度要增加很多，主要体现在以下几个方面：一是车外热负荷变化大，难以确定控制参数；二是要求空调负荷大，而且要控制空调使其降温迅速：三，不便于用电力作为动力源，必须用汽车发动机或辅助发动机来带动压缩机，当采用汽车发动机作为动力源时，由于汽车的车速变化大，发动机转速的变化可从600r min到4000r min ，压缩机转速与发动机转速成正比，其转速变化高达7倍，给空调系统制冷剂流量控制带来困难。 |
