Abstract

The embodiment of the invention provides a method for detecting refrigerant leakage and an air conditioner. The method and the air conditioner are applied to the field of air conditioner control. On the basis of that the cost of a complete machine is not increased, detection on the refrigerant leakage is realized, and the popularization and the use of the air conditioner are facilitated. The method for detecting the refrigerant leakage comprises the following steps: when continuous operation time of a compressor of the air conditioner reaches a first preset duration, obtaining the indoor ambient temperature and the temperature of an indoor heat exchanger of the air conditioner; according to the ambient temperature and the temperature of the indoor heat exchanger, confirming whether the refrigerant of the air conditioner is leaked or not. The method for detecting the refrigerant leakage, provided by the embodiment of the invention, is used for detecting whether the refrigerant of the air conditioner is leaked or not.

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 ...
