Embodiment Construction
[0032] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0033] The invention provides a detection method for air conditioner refrigerant leakage, referring to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the method for detecting refrigerant leakage of an air conditioner according to the present invention.
[0034] The embodiment of the present invention provides an embodiment of a method for detecting refrigerant leakage of an air conditioner. It should be noted that, although the logic sequence is shown in the flow chart, in some cases, all steps may be performed in a sequence different from that shown here. steps shown or described.
[0035] In this example. The air conditioner can be divided into an indoor part and an outdoor part. The structure of the indoor part mainly includes the evaporator, air duct, wind wheel and electric control ...

The invention discloses a method for detecting air-conditioner coolant leakage, an air-conditioner and a readable storage medium. The method includes the steps that the current operating state of theair-conditioner is detected, and the back temperature corresponding to a compressor inside the air-conditioner is obtained when it is detected that the air-conditioner is in an operating state; the change rate of the back temperature is calculated every first preset time to obtain a first change rate, a second change rate and a third change rate; and if the second change rate is greater than the first change rate and the third change rate is greater than the first change rate, it is determined that coolants of the air-conditioner have leaked. According to the method for detecting air-conditioner coolant leakage, the air-conditioner and the readable storage medium, whether the coolants of the air-conditioner have leaked or not is detected through the back temperature corresponding to the compressor, the condition that air-conditioner coolant leakage cannot be detected when the coolant leakage concentration is small is avoided, and the precision rate of air-conditioner coolant leakage detection is increased.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for detecting refrigerant leakage of an air conditioner, an air conditioner and a readable storage medium. Background technique [0002] At present, the market is paying more attention to the safety of home appliances, and the utilization rate of air conditioners is also getting higher and higher. However, when the refrigerant of the air conditioner leaks, it not only affects the cooling and heating effects of the air conditioner, but also has potential safety hazards. For example, for flammable refrigerants, when the refrigerant leaks too much, it may catch fire and pose a safety hazard, so it is necessary to detect whether the refrigerant leaks. At present, it is possible to determine whether the refrigerant of the air conditioner is leaking by detecting the refrigerant concentration. For example, when it is detected that the refrigerant concentration in the ...
