Title:
METHOD AND APPARATUS FOR MEASURING AMOUNT OF REFRIGERANT IN REFRIGERATION SYSTEM, AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2022/160672
Kind Code:
A1
Abstract:
A method and apparatus for measuring the amount of refrigerant in a refrigeration system, and an air conditioner. The method is applied to a refrigeration device, and the refrigeration device is provided with a pressure sensor. The method comprises: when stopping adding a refrigerant of a refrigeration system, controlling a compressor of the refrigeration device to operate at a preset frequency; after the compressor runs for a preset duration, acquiring a first pressure value collected by the pressure sensor; and according to the correspondence between pressure values and refrigerant, determining the amount of refrigerant corresponding to the first pressure value as the current remaining amount of refrigerant in the refrigeration system. By means of the described solution, the amount of refrigerant in a refrigeration system can be determined according to a collected pressure value in the refrigeration system after a maintenance worker adds the refrigerant, thus providing a user with a more accurate means for measuring the amount of refrigerant so as to determine information about the amount of refrigerant remaining in the refrigeration system and thereby determine whether the amount of refrigerant added by the maintenance worker is suitable, thus meeting the needs of users.
