The invention provides a control method and device of an air conditioning device in a vehicle, a processor and an air conditioning system. The method comprises the steps that according to the currenttemperature and the preset temperature in a passenger compartment in a vehicle, the heat exchange amount needed by the passenger compartment is calculated, and the operation mode of the air conditioning device is determined; working parameters of preset equipment in the air conditioning device are adjusted; the duty ratio of the voltage applied to the direct-current motor is reduced, and the direct-current motor is used for controlling the compressor to operate. According to the method, the difference value between the current temperature and the preset temperature in the passenger compartmentcan be reduced by adjusting the working parameters of the preset equipment, so that the comfort level of the passenger compartment can be improved, and meanwhile, the system power can be reduced by reducing the duty ratio of the voltage applied to the direct current motor, so that the system stability is improved. Therefore, the problems that the system power is difficult to reduce and the comfort of the passenger compartment is difficult to improve simultaneously in the prior art are solved.
本申请提供了一种车内空调装置的控制方法、控制装置、处理器和空调系统。该方法包括:根据车内的乘员舱内的当前温度与预设温度,计算乘员舱所需的换热量并确定空调装置的运行模式;调整空调装置中的预定设备的工作参数;减小对直流电机施加的电压的占空比,直流电机用于控制压缩机运转。该方法中,通过调整预定设备的工作参数,可以减小乘员舱内的当前温度和预设温度的差值,这样可以提高乘员舱的舒适度,同时,该方法中,通过减小对直流电机施加的电压的占空比,这样可以降低系统功率,从而解决了现有技术中难以同时降低系统功率且同时提高乘员舱的舒适度的问题。
