Abstract

The embodiment of the invention provides a method for detecting refrigerant leakage and an air conditioner, belongs to the field of air conditioner control, and aims at detecting refrigerant leakage without increasing the complete machine cost, as well as popularizing and applying the air conditioner. The method for detecting the refrigerant leakage comprises the steps of acquiring indoor environmental temperature and blowout temperature of an indoor air outlet of the air conditioner when a continuous working hours of a compressor of the air conditioner reaches the first preset length of the time; then determining whether a refrigerant of the air conditioner leaks according to the environmental temperature and the blowout temperature. With the adoption of the method, the refrigerant leakage of the air conditioner leaks can be detected.

Description

technical field [0001] The invention relates to the field of air conditioner control, in particular to a method for detecting refrigerant leakage and an air conditioner. Background technique [0002] At present, commonly used household air conditioners include two parts: an indoor unit and an outdoor unit. The entire air conditioning system includes a compressor, an outdoor heat exchanger, a throttling device, and an indoor heat exchanger. There is also a refrigerant in the air conditioning system. The refrigerant is driven by the pressure generated by the compressor, circulates in the entire system, and exchanges heat with the indoor and outdoor environments to achieve the purpose of cooling or heating. Therefore, the amount of refrigerant directly affects the performance of the air conditioner. Cooling and heating effects. However, during the installation or use of the air conditioner, there may be long-term slow leakage of refrigerant caused by the high and low pressure ...
