基于回差技术的汽车空调制冷系统控制电路的设计

On the Design of Control Circuit for Automotive Air Conditioning System Based on Hysteresis Technique

各种原因引起的蒸发器温度波动,造成汽车空调系统的核心部件压缩机不合理的频繁启动和停止,影响了制冷效力。为避免此种情况,有效保障压缩机正常运行,研究了一种基于回差技术且适合经济型汽车空调系统使用的控制电路。

Due to the evaporator temperature vibration caused by various factors, the compressor, the most essential component of the automotive air conditioning system, has to start and stop frequently, affecting the cooling efficiency. In order to avoid this situation and ensure the normal operation of the compressor, the authors of this paper have developed a control circuit for the air conditioning system of economical vehicles based on hysteresis technology.
