The invention discloses an automobile
thermal management system control method which comprises the following steps: receiving a
signal for turning on a back-row air conditioner, determining that the back-row air conditioner meets a
refrigeration requirement, and turning on a valve piece communicated with a back-row
evaporator; receiving a battery quick-charging
signal, and adjusting the rotating speed of a compressor to control the inlet
water temperature of a battery
heat exchanger; after the valve communicating with the rear-row
evaporator is opened for a preset time, when the
water temperature of the inlet of the battery
heat exchanger is smaller than or equal to the target
water temperature, the valve communicating with the rear-row
evaporator is kept opened; and when the feedback rotating speed of the compressor is equal to the rated highest rotating speed of the compressor, closing a valve communicated with the rear-row evaporator. According to the control method and device, the valve communicating with the rear-row evaporator is controlled according to the water temperature of the inlet of the battery
heat exchanger and the feedback rotating speed of the compressor, and it can be guaranteed that the compressor operates at the rated highest rotating speed all the time under the condition that the water temperature of the inlet of the battery heat exchanger does not reach the standard; the valve communicated with the rear-row evaporator is allowed to be closed, the
refrigeration requirements of the battery side and the front-row air conditioner are preferentially guaranteed, more refrigerants flow into the battery side and the front-row evaporator, and therefore the water temperature of the battery side and the temperature of the front-row evaporator are reduced, the comfort of passengers in a passenger compartment is improved, and the battery is rapidly cooled. The invention further provides a method, a device, equipment and a medium.
