Automobile air conditioner control method and device, storage medium and automobile air conditioner
By judging the ambient temperature outside the car and the running time of the air conditioner, the cooling fan or electric heating device of the car air conditioner is used to melt the ice and snow, which solves the problem of reduced heating effect and increased power consumption of the overhead air conditioner due to ice and snow coverage, and improves the operation of the air conditioner. efficiency and user experience.

AI Technical Summary
In ice and snow weather, roof-mounted car air conditioners are covered with ice and snow, resulting in poor air intake or exhaust. The heat exchange efficiency of the heat exchanger decreases, frost appears on the unit, and the heating effect becomes worse. The temperature inside the car is low, which reduces the user experience and increases power consumption.
By obtaining the ambient temperature outside the vehicle and the accumulated heating operation time of the air conditioner, it is determined whether the air outlet and/or air inlet are covered with ice and snow, and the cooling fan or electric heating device of the outside heat exchanger is used to melt the ice and snow to ensure that the air outlet is unobstructed. .
It effectively solves the problem of reduced air conditioning heating effect caused by ice and snow cover, reduces frequent defrost of the unit, saves electricity, and improves snow melting efficiency through auxiliary electric heating.
