Title:
METHOD AND APPARATUS FOR DETECTING REFRIGERANT ANOMALY, AND AIR CONDITIONER AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/041014
Kind Code:
A1
Abstract:
The present application relates to the technical field of intelligent household appliances. Disclosed is a method for detecting a refrigerant anomaly, which method is applied to a heating operation condition of an air conditioner. The method comprises: when a continuous operation duration of a compressor is greater than or equal to a preset duration, detecting the current indoor environment temperature Tr, the current indoor coil temperature Tp and the current outdoor environment temperature To; when an air conditioner is of a fixed-frequency model, analyzing the condition of refrigerant circulation according to Tr, Tp and the current state of the compressor; when the air conditioner is of a variable-frequency model, analyzing the condition of refrigerant circulation according to Tr, Tp, To and the current state of the compressor; and when refrigerant circulation is anomalous, outputting prompt information indicating that refrigerant circulation is anomalous. The method improves the accuracy of detecting a refrigerant leakage in a heating state. Also disclosed in the present application is an apparatus for detecting a refrigerant anomaly, and an air conditioner and a storage medium.
