Abstract

The invention discloses a refrigerant detection method and device for an air conditioning system, an air conditioner and a storage medium. Wherein, the method includes: obtaining the temperature change of the first target component pipeline and the pressure change of the second target component pipeline in the air conditioning system, wherein the temperature change is detected by a temperature sensing device, and the pressure change is detected by a pressure detection It is detected by the device; based on at least one of the temperature change and the pressure change, it is judged whether there is refrigerant leakage in the air-conditioning system; if it is determined that there is refrigerant leakage in the air-conditioning system, an alarm is issued. The invention solves the technical problem in the related art that the cost of installing the concentration detection device in the air-conditioning system is relatively high, which causes the user's interest in purchasing the air-conditioner to decline.

Description

technical field [0001] The present invention relates to the technical field of air conditioning control, in particular to a refrigerant detection method and device for an air conditioning system, an air conditioner, and a storage medium. Background technique [0002] In the related technology, a gas detection device will be installed in the air conditioner to detect whether the air conditioner will leak refrigerant. This is the current destruction of the ozone layer and greenhouse gases in the atmosphere, which makes more and more natural refrigerants such as R290 and R32. Used in household air conditioners, these natural refrigerants are generally flammable gases. Once used in household air conditioners, leakage will cause certain impacts and safety hazards on the health, life and property of indoor personnel. Considering the safe use of air-conditioning, many air-conditioning companies now install combustible gas concentration detection devices on indoor air conditioners. ...
