该文所用方法对于燃气舵的气动设计、辅助发动机点火试验具有指导意义。 - 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。 - This controlling way can make the passengers feel much comfortable and make the bus air - conditions work with a high efficiency . in this thesis , a single - chip microcomputer fuzzy controlling system with mcu : at89c51 is designed to deal with the bus whole air - condition composed with refrigerating system and heating system . via controlling the open of temperature door , turnaround speed of evaporator fan and subsidiary engine , it can control temperature of railway carriage
本论文针对独立式全空调型(完全合一型)客车空调系统，设计了一个以at89c51为核心的采用模糊控制算法的嵌入式单片机控制系统，通过控制温度门的开口角度、蒸发器风扇的转速、辅助发动机的转速来控制车厢内的温度，通过压缩机的开、停对蒸发器除霜，系统具有温度显示、用户设定的分挡多级温度控制、在线控制参数修改等功能。
