Air conditioner control device, air conditioner and control method thereof

Abstract

The invention discloses an air conditioner control device, an air conditioner and a control method of the air conditioner. The device comprises a collection module and a power conversion module. The collection module is used for collecting the refrigerant temperature of a compressor of the air conditioner, and pulling down an enable signal of the power conversion module to a set value under the condition that the refrigerant temperature falls to the set low temperature after the compressor is shut down. The power conversion module is used for entering a set power consumption control mode underthe condition that the enable signal is of the set value. By means of the scheme, the problem that the shutdown reliability is poor when the automobile air conditioner is shut down in the heating state can be solved, and the effect of improving the shutdown reliability can be achieved.

Description

technical field [0001] The invention belongs to the technical field of electronic circuits, and in particular relates to an air conditioner control device, an air conditioner and a control method thereof, in particular to a low power consumption circuit with an adaptive function, an air conditioner and a control method thereof. Background technique [0002] With the rapid development of electric vehicles, electric vehicle air conditioners with heating function have also become the focus of many manufacturers. Since air conditioners are also components that consume a lot of power, they need to enter a low power consumption mode in standby mode to reduce power consumption. Power consumption in standby mode. [0003] For example: when the car air conditioner is shut down in the heating state, if the power is cut off prematurely, the three-way valve will be switched instantaneously, causing the flow of the refrigerant to be blocked and a strong impact sound will be emitted, whic...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to address the above defects, to provide an air conditioner control device, an air conditioner and a control method thereof, so as to solve the phenomenon of refrigerant collision caused by premature power failure in the prior art when the automobile air conditioner is shut down in the heating state, Waiting for a long time to cut off the power will bring a lot of power consumption, and there is a problem of poor shutdown reliability, so as to improve the shutdown reliability and reduce unnecessary power consumption.
