Document Type and Number:
WIPO Patent Application WO/2023/083040
Kind Code:
A1
Abstract:
Some embodiments of the present disclosure provide an air conditioner, and relate to the technical field of air conditioning apparatuses. The air conditioner comprises an outdoor unit, at least one indoor unit, a refrigerant filling device, and a controller. The outdoor unit comprises a compressor and a first heat exchanger. Each indoor unit comprises a second heat exchanger. The refrigerant filling device is configured to provide a refrigerant. The controller is coupled to the compressor and the refrigerant filling device, and is configured to: control the air conditioner to enter a refrigeration working state in response to having received a refrigerant filling instruction; obtain a supercooling degree threshold value of a liquid discharge port of the first heat exchanger, the supercooling degree threshold value being determined according to a first internal volume of the outdoor unit and a second internal volume of the at least one indoor unit; obtain a supercooling degree at the liquid discharge port of the first heat exchanger every first time period; control the refrigerant filling device to fill the compressor with the refrigerant if the supercooling degree is smaller than the supercooling degree threshold value; and control the refrigerant filling device to stop filling the compressor with the refrigerant if the supercooling degree is greater than or equal to the supercooling degree threshold value.
