AIR CONDITIONER AND CONTROL METHOD THEREOF

WIPO Patent Application WO/2021/223697

A1

Disclosed are an air conditioner and control method thereof; the air conditioner, on a parallel branch, is provided with a flow-regulating valve, an evaporation module, and a branch temperature/pressure acquisition module; collecting branch state data Ti of each branch by means of the branch temperature/pressure acquisition module; collecting compressor suction state data K by means of a compressor suction temperature/pressure acquisition module; according to the relationship between the compressor suction state data K and an optimal interval of compressor suction temperature/pressure [A, B], the relationship between the difference between the compressor suction state data K and the branch state data Ti and an optimal interval [C, D] of the difference between the two, controlling the degree of opening of the corresponding flow-regulating valve, causing the flow into the evaporator to be more uniform and improving the uneven frosting of the fin heat exchanger, while ensuring a safe compressor suction temperature/pressure, ensuring that there is no liquid at the suction port of the compressor, thus ensuring the service life of the compressor.
