Document Type and Number:
WIPO Patent Application WO/2022/222484
Kind Code:
A1
Abstract:
A vehicle-mounted air conditioner and a control method therefor. The control method comprises: obtaining the cumulative use duration of a storage battery, the current electric quantity of the storage battery, a vehicle external ambient temperature, a vehicle internal ambient temperature, a target temperature, and a target operation duration; determining the maximum allowable output current according to the cumulative use duration, the current electric quantity, and the target operation duration; determining a first operating frequency according to the maximum allowable output current, determining a second operating frequency according to the vehicle external ambient temperature, determining a third operating frequency according to the vehicle internal ambient temperature and the target temperature, and selecting a minimum value among the first operating frequency, the second operating frequency and the third operating frequency as a target operating frequency; and controlling a compressor of a vehicle-mounted air conditioner to operate according to the target operating frequency, thereby solving the technical problem that vehicle-mounted air conditioners supplied with existing storage batteries often have insufficient battery electric quantities, which causes the vehicle-mounted air conditioners to shut down midway and fail to meet vehicle internal temperature adjustment requirements.
