Air conditioner and control method thereof

Abstract

The invention relates to the technical field of air conditioners, and discloses an air conditioner and a control method of the air conditioner. According to the control method of the air conditioner,when the air conditioner is in a heating state, even if the frequency of a compressor is reduced to the lowest frequency, the temperature of an inner coil is still high, the air conditioner can enhance indoor side heat exchange or inhibit outdoor side heat exchange by increasing the air amount of an inner fan or reducing the air amount of an external fan, so that the condensation temperature of air conditioner heat pump circulation is increased or the evaporation temperature of air conditioner heat pump circulation is reduced, the operation pressure of a unit is reduced, and the reliability ofair conditioner heating operation is improved. Under the control method, the air conditioner is not prone to the problem of shutdown which is caused because the frequency of the compressor is reducedto the lowest frequency but the unit operation pressure is not relieved, so that the use experience of a user is improved. The air conditioner can realize the control method, thereby having the corresponding beneficial effects of the control method.

Description

technical field [0001] The present application relates to the technical field of air conditioners, in particular, to an air conditioner and a control method thereof. Background technique [0002] During the daily operation of the air conditioner, if there is too much dust on the indoor filter, it is easy to cause the indoor filter to be dirty and clogged, which is reflected in the small air volume on the indoor side, poor heat exchange, and high operating pressure of the unit, which will affect the reliability of the unit. . [0003] Under the heating condition of the existing air conditioners, when the operating pressure of the unit is high, there is a single mitigation method, and the usual method is to reduce the frequency. Therefore, it is easy to reduce the frequency and cannot solve the problem of high temperature shutdown protection due to high operating pressure, resulting in poor user experience. Contents of the invention [0004] The problem to be improved in t...

Problems solved by technology

[0002] During the daily operation of the air conditioner, if there is too much dust on the indoor filter, it is easy to cause the indoor filter to be dirty and clogged, which is reflected in the small air volume on the indoor side, poor heat exchange, and high operating pressure of the unit, which will affect the reliability of the unit.

[0003] Existing air conditioners have a single mitigation method when the operating pressure of the unit is high under heating conditions, and the usual method is to reduce the frequency

Therefore, it is easy to reduce the frequency and cannot solve the problem of high temperature shutdown protection due to high operating pressure, resulting in poor user experience
