Problems solved by technology

[0004] However, at the moment when the electromagnetic valve is suddenly opened, a large amount of refrigerant will pour into the compressor, which will easily cause a sudden change in the overall power of the compressor, resulting in out-of-step control or failure of the compressor.

Abstract

The invention discloses a control method of an air-injection enthalpy-increasing air-conditioning system, relates to the technical field of air conditioning, and aims to solve the technical problem in the related art that the air-conditioning system loses control step or is prone to failure during the air-supplementing operation. An embodiment of the present invention provides a control method for an air-conditioning system that increases enthalpy by air injection. The control method includes: in the heating and air supplement mode, turning on the compressor; obtaining the actual temperature of the refrigerant at the suction port of the flasher in real time, The actual temperature and the corresponding refrigerant target temperature determine the first temperature difference; determine whether the first temperature difference is less than the first threshold M, if yes, open the solenoid valve, if not, adjust the first throttle valve and the second throttle valve according to the first temperature difference The opening degree of the throttle valve, and obtain the adjusted actual temperature of the refrigerant to determine the second temperature difference between the adjusted actual temperature of the refrigerant and the target temperature of the refrigerant, and open the solenoid valve when the second temperature difference meets the first preset condition . The invention can be used for air conditioning.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a control method for an air-injection enthalpy-increasing air-conditioning system. Background technique [0002] With the development of science and technology, jet enthalpy air conditioning system has been widely used. [0003] In related technologies, an air-injection enthalpy-increasing air-conditioning system includes a compressor, a flasher, an indoor heat exchanger, an outdoor heat exchanger, a first throttle valve, a second throttle valve, and a solenoid valve. Among them, the first throttle valve is connected between the flasher and the indoor heat exchanger, the second throttle valve is connected between the flasher and the outdoor heat exchanger, and the solenoid valve is connected between the flasher and the compressor . When the air-injection enthalpy-increasing air-conditioning system is running in the air supply mode, the compressor can be supplied with a...
