The present invention is applicable to the technical field of fault detection, and provides an air conditioner fault detection method and device. The detection method includes: obtaining the outdoor temperature, the exhaust pressure of the air conditioner, the suction pressure of the air conditioner, and the supercooling degree of the air conditioner; When the outdoor temperature, the exhaust pressure, the suction pressure, and the degree of subcooling meet the first preset condition, it is determined that the air conditioner has a fault of refrigerant leakage or insufficient filling. This method establishes multiple factors including outdoor temperature, air-conditioning exhaust pressure, air-conditioning suction pressure and air-conditioning subcooling degree as the detection logic of detection conditions, which improves the accuracy of fault detection of air-conditioning refrigerant leakage or insufficient filling. sex.
Description
technical field [0001] The invention belongs to the technical field of fault detection, in particular to an air conditioner fault detection method and device. Background technique [0002] In recent years, with the rise of global temperature and the substantial improvement of people's living standards, air-conditioning equipment has gradually become one of the necessary electrical appliances in life. With the increasingly fierce market competition, the working efficiency and safety of air-conditioning are becoming more and more Become one of the main factors affecting the core competitiveness of products. [0003] In actual use, air-conditioning system failures caused by refrigerant leakage or insufficient filling often occur, which seriously reduces product competitiveness. On the one hand, the leakage of refrigerant will reduce the working efficiency of the air conditioner. At the same time, the leakage of refrigerant will cause damage to the ozone layer and cause a serie...
