Title:
HYDROGEN GAS LEAKAGE DETECTION METHOD AND DEVICE FOR AIR CONDITIONER USING ELECTROCHEMICAL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2019/169897
Kind Code:
A1
Abstract:
Disclosed by the present invention is a hydrogen gas leakage detection method and device for an air conditioner using an electrochemical compressor, belonging to the technical field of air conditioners. The detection method comprises: acquiring a first inlet air temperature and a first outlet air temperature of an air conditioner; determining whether a first temperature difference between the first inlet air temperature and the first outlet air temperature is less than a preset temperature deviation value; and in response to a determination result that the first temperature difference is less than the preset temperature deviation value, determining that the air conditioner has a hydrogen gas leakage fault. According to the hydrogen gas leakage detection method provided by the present invention, it is possible to determine whether there is a hydrogen gas leakage according to the degree of change in the temperature difference between the inlet air and outlet air of the air conditioner. The detection is accurate, the real-time performance is strong, and the influence of the operation adjustment of the system on the method is small. The detection and early warning of the hydrogen gas leakage of the air conditioner can greatly improve the performance and prolong the life of the air conditioner system.
