Abstract

The invention discloses an air conditioner control method and an air conditioner system. The method comprises the steps that an indoor unit or an outdoor unit obtains the air suction pressure and the air suction temperature of a compressor, and the superheat degree of the compressor is obtained according to the air suction pressure and the air suction temperature; and the indoor unit or the outdoor unit adjusts the starting step number of an overheating bypass motor according to the superheat degree so as to adjust the amount of exhausted gas, entering a double-channel heat exchanger, of the compressor. The starting step number of the overheating bypass motor is adjusted according to the current superheat degree of an air conditioner so as to adjust the amount of exhausted gas, entering the double-channel heat exchanger, of the compressor, so that the heat exchange degree of return air from an evaporator to the compressor in the double-channel heat exchanger can be achieved, the heat absorption evaporation degree of a refrigerant circulated to the compressor is improved, the superheat degree of the compressor is improved, and the normal refrigeration of the air conditioner is maintained.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method and an air conditioner system. Background technique [0002] In data center refrigeration, the reliable operation of the air conditioning system is very important. If the superheat of the compressor is low, the compressor will run with liquid, and the system will not be able to cool normally. When there are many devices, the temperature in the computer room will quickly get out of control. [0003] Therefore, the prior art still needs to be improved and improved. Contents of the invention [0004] The invention provides an air-conditioning control method and an air-conditioning system, aiming at solving the problem in the prior art that the superheat of the compressor is out of control and the air-conditioning system cannot normally cool down. [0005] In order to solve the problems of the technologies described above, the technical ...
