1results about How to "Maximize effectiveness" patented technology

The application relates to the technical field of intelligent air conditioners, and provides an air conditioner refrigerant self-adaptive control method and device, which comprises the following steps: detecting the actual superheat degree, system high-pressure pressure and actual opening degree of an electronic expansion valve of an air conditioner under the condition that the fan rotating speed of the air conditioner and the frequency of a compressor remain unchanged; the system high-pressure pressure is the pressure value of the exhaust pipe of the compressor; and based on the actual superheat degree, the system high-pressure pressure, the actual opening degree of the electronic expansion valve and a preset target threshold value, triggering the opening of an electromagnetic valve of a liquid storage tank to adjust the refrigerant amount in the air conditioner. The air conditioner refrigerant self-adaptive control method can effectively improve the adjustment control accuracy of the refrigerant amount, so that the refrigerant amount participating in the circulation is at an optimal value, thereby maximizing the performance of the air conditioning system.
