Abstract

The invention discloses a compressor overload protection control method and device as well as a fixed-frequency air conditioner. The compressor overload protection control method comprises the following steps: detecting the state of a compressor in the air conditioner to obtain a detection result; judging whether the compressor has overload protection according to the detection result; if yes, controlling the draught fan of the air conditioner to stop operation. Through the compressor overload protection control method and device, the possibility that a system pipeline explodes easily caused by the situation that the compressor has overload protection is reduced.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a compressor overload protection control method and device and a fixed-frequency air conditioner. Background technique [0002] With the development of society, the problems of energy and environment are becoming more and more prominent, especially in terms of energy consumption and environmental pollution and destruction. How to take effective solutions in these aspects has also attracted more and more attention. At present, most household air conditioners in China use the traditional refrigerant R22. R22 refrigerant is a refrigerant widely used in Freon refrigerants. It greatly damages the ozone layer and seriously endangers the human living environment and the overall ecological environment. , will be phased out gradually. R410A refrigerant is a refrigerant that is used as a substitute for R22. It does not destroy the ozone layer and makes the air conditioner work more effici...
