A detection and control method for overload protection, a computer-readable storage medium, and an air conditioner

Abstract

The invention provides a detection and control method for overload protection, a computer-readable storage medium, and an air conditioner. The steps of the detection and control method for overload protection are: acquiring the indoor ambient temperature T inner ring and the inner ring of the evaporator every K seconds Tube temperature Tinner tube, according to the change trend of indoor ambient temperature Tinner ring and evaporator inner tube temperature Tinner tube within a judgment period t interval time, judge whether the compressor enters overload protection. The detection and control method of the overload protection of the present invention does not need to add any parts and additional costs, and can accurately identify whether the overload protector of the compressor is activated, so as to control the air conditioner to stop running in time, thereby improving the reliability of the compressor and service life, improve product quality.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a detection and control method for overload protection, a computer-readable storage medium and an air conditioner. Background technique [0002] The compressor of the air conditioner usually comes with an overload protector. The overload protector is generally composed of a terminal, a heating wire, a contact, a bimetal, a moving piece and a shell. The most important part is the bimetal. The overload protector It is to control the start and stop of the compressor by automatically jumping and closing according to the physical characteristics of the bimetallic strip, so as to protect the compressor and prevent the compressor from being burned and damaged. [0003] The air conditioner operates under severe conditions such as high temperature or heavy load, and the motor will not burn out under short-term operation due to the protection of the overload protector. However, e...

AI Technical Summary

Problems solved by technology

Long-term operation under harsh conditions such as high temperature or heavy load, due to frequent cumulative effects, will eventually lead to compressor motor burnout

[0004] Existing fixed-frequency air conditioners are limited by cost, and parameters such as pressure and current cannot be read. In this way, it is difficult to be directly detected by the controller of the air conditioner if the overload protector of the air conditioner compressor is disconnected.
