Title:
AIR CONDITIONER ALL-SCENARIO HIGH-EFFICIENCY CONTROL SYSTEM AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/030181
Kind Code:
A1
Abstract:
The present invention provides an air conditioner all-scenario high-efficiency control system and a control method therefor. A refrigerant transfer device is used to provide a refrigerant to a refrigerant circulation loop or recover a refrigerant from the refrigerant circulation loop; a valve unit is located between the refrigerant transfer device and the refrigerant circulation loop; an environment parameter measuring module is used to measure environment parameters; a storage module is used to store an optimal refrigerant amount of the refrigerant circulation loop corresponding to the environment parameters; and a control module is used to obtain the optimal refrigerant amount of the refrigerant circulation loop corresponding to the environment parameters and to control, according to the relationship between the refrigerant amount of the current refrigerant circulation loop and the optimal refrigerant amount, the states of the valve unit and the refrigerant transfer device, so that the refrigerant amount in the refrigerant circulation loop reaches the optimal refrigerant amount. The present invention can flexibly control the refrigerant amount in a refrigerant circulation loop of an air conditioner, so that under different environment parameter conditions, the optimal refrigerant amount that is matched with the refrigerant circulation loop in the described environment parameter scenario so as to achieve optimal energy efficiency.
