Problems solved by technology

[0003] When the indoor fan of the air conditioner is running, even if refrigerant leakage occurs, the leaked refrigerant will quickly spread to other indoor areas under the influence of the air from the indoor unit, so that the concentration of refrigerant detected by the refrigerant sensor is lower than the actual concentration of refrigerant leakage. The leakage alarm is not timely, which increases the risk of refrigerant leakage

Embodiment Construction

[0042] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0043] The embodiment of the present invention provides a solution. When the indoor fan is running, a preset operation is performed to slow down the air flow in the space where the refrigerant sensor is located. Due to the influence of the concentration of the air conditioner, the detection of refrigerant leakage is more timely, and the safety of the refrigerant of the air conditioner is improved.

[0044] like figure 1 shown, figure 1 It is a schematic diagram of the terminal structure of the hardware operating environment involved in the solution of the embodiment of the present invention.

[0045] The terminal in the embodiment of the present invention is an air conditioner, and the air conditioner is provided with a refrigerant sensor, and the refrigerant sensor is used to detect whether the refrigerant ci...

Abstract

The invention discloses a refrigerant leakage detection method which comprises the following steps: when an indoor fan of an air conditioner runs, acquiring a first concentration detected by a refrigerant sensor of the air conditioner; when the first concentration is smaller than the preset concentration, preset operation is executed so as to slow down air flow in the space where the refrigerant sensor is located; after the preset operation is executed, second concentration detected by the refrigerant sensor is obtained; and whether refrigerant leakage exists or not is judged according to the second concentration. The invention further discloses the air conditioner and a computer storage medium. When the indoor fan runs, the preset operation is executed to slow down air flow in the space where the refrigerant sensor is located, and by reducing diffusion of leaked refrigerants and reducing the influence of air flow acceleration of the indoor fan on the concentration detected by the refrigerant sensor, refrigerant leakage detection is more timely, and the safety of the refrigerants of the air conditioner is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a method for detecting refrigerant leakage, an air conditioner and a computer storage medium. Background technique [0002] In an air conditioning system, a refrigerant sensor is usually provided to detect whether there is refrigerant leakage. When the refrigerant concentration detected by the refrigerant sensor is greater than the set alarm value, the refrigerant sensor will alarm. [0003] When the indoor fan of the air conditioner is running, even if a refrigerant leak occurs, the leaked refrigerant will quickly spread to other indoor areas under the influence of the air outlet from the indoor unit, so that the refrigerant concentration detected by the refrigerant sensor is lower than the actual concentration of the refrigerant leakage. The leakage alarm is not timely, which increases the risk of refrigerant leakage. [0004] The above content is only used t...
