Document Type and Number:
WIPO Patent Application WO/2024/077989
Kind Code:
A1
Abstract:
An air conditioner and a control method therefor. The air conditioner comprises an outdoor unit (12), an indoor unit (11), a compressor (121), and a controller (15). The indoor unit (11) is communicated with the outdoor unit (12). The controller (15) is configured to: in a refrigerant recovery process, acquire the current air discharge pressure and air suction pressure of the compressor (121); determine the compression ratio of the compressor (121) according to the air discharge pressure and the air suction pressure of the compressor (121); determine a calculated rotational speed adjustment value of the compressor (121) according to the compression ratio of the compressor (121) and a preset target compression ratio; and determine a target rotational speed of the compressor (121) according to the current rotational speed and the calculated rotational speed adjustment value of the compressor (121), and control the compressor (121) to operate at the target rotational speed.
