Problems solved by technology

[0003] In the air conditioning control system and method in the prior art, the evaporator protection temperature is set to prevent the evaporator from frosting and affect the working efficiency of the air conditioner
Among them, the evaporator protection temperature in the prior art is a fixed value, which will not change after setting and debugging, and it is impossible to realize that the evaporator protection temperature changes with the indoor temperature.
In addition, most vehicle air conditioner compressors are fixed-di

Abstract

The invention discloses an air conditioner control system, which is characterized in that a control module adjusts the protection temperature of an evaporator according to the indoor temperature. Specifically, in a refrigeration mode of an air conditioner, the control module adjusts the stop temperature of the air conditioner to decrease along with the increase of the indoor temperature, while thecontrol module adjusts the start temperature of the air conditioner to increase along with the increase of the indoor temperature. In the heating mode of the air conditioner, the control module adjusts the stop temperature of the air conditioner to rise along with rising of indoor temperature, and the control module adjusts the start temperature of the air conditioner to decrease along with rising of the indoor temperature. Therefore, the protection temperature of the evaporator changes along with the indoor temperature. The evaporator of the air conditioner is protected more actively.

Description

technical field [0001] The invention relates to the field of air-conditioning control, in particular to an air-conditioning control system and method. Background technique [0002] The prior art provides an air conditioner control system and method, which relate to the technical field of electric vehicles. The system includes: a temperature controller, used for comparing the temperature voltage signal detected by the evaporator outlet temperature detector with the sampling voltage signal output by the potentiometer, and controlling the motor of the air conditioner compressor according to the comparison result; A temperature detector, connected to the temperature controller, for detecting the temperature at the outlet of the air conditioner evaporator, and sending the detected temperature signal to the temperature controller; a potentiometer, connected to the temperature controller, for Outputting a sampling voltage signal corresponding to the target temperature to the tempe...
