Over-load protection method, device and storage medium for air conditioner and air conditioner

Abstract

The invention discloses an over-load protection method, a device and a storage medium for an air conditioner and an air conditioner. The over-load protection method comprises the following steps thatthe current of the whole machine of the air conditioner and the current exhaust temperature of the compressor are acquired; determining whether the current is larger than or equal to the set current upper limit value, or whether the current exhaust temperature is larger than or equal to the set temperature upper limit value; and if the current is smaller than the set current upper limit value, thecurrent exhaust temperature is smaller than the set temperature upper limit value, and the over-load protection of the air conditioner is achieved according to the reference exhaust temperature corresponding to the current. According to the over-load protection method, the problem that in the prior art, the control precision is low due to the fact that a built-in overload protector or an externaloverload protector needs to be installed in a constant-frequency air conditioning compressor in the prior art is solved, so that the effect of improving the control precision is achieved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically relates to an air conditioner overload protection method, device, storage medium and air conditioner, in particular to an air conditioner overload protection control method, a device corresponding to the method, an air conditioner with the device, and a storage medium. A computer-readable storage medium having instructions corresponding to the method, and an air conditioner capable of executing the instructions corresponding to the method. Background technique [0002] The fixed-frequency air conditioner compressors currently on the market need to be installed with a built-in overload protector (for example: a mechanical overload protector installed on the outside of the compressor) or an external overload protector (for example: installed on the inside of the compressor near the glass body) , the principle is to avoid safety problems caused by excessive current or high ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to address the above defects, to provide an air conditioner overload protection method, device, storage medium and air conditioner, so as to solve the problem that the fixed frequency air conditioner compressors in the prior art need to be installed with a built-in overload protector or an external overload protector. There is a problem of low control precision in the overload protection of the device, so as to achieve the effect of improving the control precision
