Abstract

The invention provides a refrigerant leakage protection control method, a controller and an air conditioner. The refrigerant leakage protection control method comprises the steps of acquiring a current operation condition of the air conditioner, acquiring maximum frequency and target exhaust temperature corresponding to the current operation condition according to the current operation condition, and adjusting the maximum frequency under the current operation condition according to a preset control strategy if detecting that the exhaust temperature of a compressor is greater than the target exhaust temperature under the current operation condition for a first preset time period, so as to reduce the maximum frequency under the current operation condition. The method can protect the air conditioner, without delaying the operation of the air conditioner when a refrigerant leaks.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of air conditioners, and in particular to a method for protecting and controlling refrigerant leakage, a controller, and an air conditioner. Background technique [0002] At present, many inverter air conditioners have forecasted the problem of refrigerant leakage, but they only stay in the forecast stage, and can only inform the user that the air conditioner in use has a refrigerant leakage fault. Once this fault is reported, the refrigerant is basically leaked. , the air conditioner has also been severely damaged. Contents of the invention [0003] Aiming at the problems in the prior art, the present invention provides a refrigerant leakage protection control method, a controller, and an air conditioner. The refrigerant leakage protection control method provided by the present invention can provide air conditioning without delaying the operation of the air conditioner when refri...
