The invention discloses an air conditioning device control system and method and an excavator. The air conditioning device control system comprises an air conditioning control module, a compressor, an electromagnetic reversing valve, a condenser, an expansion valve, an evaporator, a water pump, a water tank, an electromagnetic valve, a radiator and a water heater. The air conditioner control module is used for controlling the compressor, the electromagnetic reversing valve, the water pump, the electromagnetic valve and the water heater. The working modes of the air conditioning device control system comprise a ventilation mode, a refrigeration mode and three heating modes, and after different working modes are selected, different parts are controlled to work through the air conditioning control module, so that the ventilation/refrigeration/heating effect is achieved. When heating is needed, different heating modes are started according to a detected temperature signal and comparison with a temperature set value. Electric heating is carried out through the electric drive cooling liquid, heat exchange of the compressor and the water heater, heat sources are provided in multiple modes, the heating efficiency is improved, the power consumption is reduced, and the endurance time of the electric excavator is prolonged.

    本发明公开了一种空调装置控制系统、控制方法及挖掘机,所述空调装置控制系统包括空调控制模块、压缩机、电磁换向阀、冷凝器、膨胀阀、蒸发器、水泵、水箱、电磁阀、散热器、水加热器;所述空调控制模块用以控制压缩机、电磁换向阀、水泵、电磁阀、水加热器。空调装置控制系统的工作模式包括通风模式,制冷模式及三种制热模式,选择不同工作模式后,通过空调控制模块控制不同部件工作,完成通风/制冷/制热效果。当需要制热的情况下,根据检测温度信号并与温度设定值进行对比,开启不同的制热模式。本发明通过电驱冷却液、压缩机热交换以及水加热器进行电加热,多种方式提供热源,提高制热效率,降低耗电量,使电动挖掘机续航时间延长。
