Control method for air conditioner of vehicle and air conditioner of vehicle

Abstract

The invention relates to the technical field of air conditioners, particularly provides a control method of an air conditioner for a vehicle and the air conditioner for the vehicle, and aims to solve the problem of high energy consumption during operation of an existing vehicle air conditioner. A front air inlet is formed in the front side wall, in the advancing direction of a vehicle, of the air conditioner, and the control method comprises the steps that the running speed of the vehicle is obtained, the running speed of the vehicle is compared with a preset vehicle speed threshold value, and the on-off state of an outer draught fan is determined based on the comparison result; under the condition that the external fan is determined to be in the starting state, at least two different preset rotating speeds are selected based on the running speed of the vehicle; and the temperature set by the user and the external temperature of the environment where the vehicle is located are obtained, the temperature set by the user is compared with a first preset temperature threshold value, the external temperature is compared with a second preset temperature threshold value, the target rotating speed of the outer draught fan is determined based on the comparison result and the selected preset rotating speed, and the outer draught fan operates at the target rotating speed. The energy consumption of the vehicle air conditioner during operation can be reduced.
