Problems solved by technology

[0002] At present, most of the fixed-frequency air conditioners are under the condition of high outdoor temperature, and the outdoor chance of the air conditioner will be protected by the high temperature tripping of the motor. After the tripping, the motor will start and stop periodically, which seriously affects the use of customers and the life of the compressor.

Abstract

The invention provides a control method and device for preventing motor overload protection and an air conditioner, and relates to the technical field of air conditioners. The control method comprisesthe following steps: receiving outdoor temperature data; judging whether the outdoor temperature data is greater than or equal to a first preset temperature; if the outdoor temperature data is largerthan or equal to the first preset temperature, controlling a motor of the air conditioner to operate at a rotating speed lower than a set rotating speed, and adjusting the opening degree of a throttling device of the air conditioner to improve the heat exchange amount of the air conditioner. According to the invention, the control method and device can achieve the motor overload protection underthe condition that the outdoor temperature is very high, provide a large heat exchange amount, and guarantee the use comfort and the service life of a compressor.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a control method and device for preventing motor overload protection and an air conditioner. Background technique [0002] At present, most of the fixed-frequency air conditioners are under the condition of high outdoor temperature, and the outdoor chance of the air conditioner will be protected by the high temperature tripping of the motor. After the tripping, the motor will start and stop periodically, which seriously affects the use of customers and the life of the compressor. . Contents of the invention [0003] The problem solved by the invention is to prevent the motor from overload protection under the condition of high outdoor temperature, and provide a larger heat exchange rate to ensure the user's use and the life of the compressor. [0004] In order to solve the above problems, the present invention provides a control method for preventing motor overload pr...
