Problems solved by technology

[0004] However, at the moment when the solenoid valve is suddenly opened, due to the sudden change in pressure, it is easy to cause a large amount of liquid refrigerant to flow into the compressor together with the gas refrigerant, causing the compressor to spray gas and return liquid, which in turn leads to compressor failure.

Abstract

The invention discloses an air-injection enthalpy-increasing air-conditioning system and a control method thereof, relates to the technical field of air conditioning, and aims to solve the technical problem of compressor air-injection and liquid return in the related art. An embodiment of the present invention provides an air-injection enthalpy-increasing air-conditioning system, which includes a compressor, a flasher, an indoor heat exchanger, and an intermediate heat exchanger. The intermediate heat exchanger includes a first pipeline and a second pipeline. The first pipeline communicates with the indoor heat exchanger and the flasher respectively, and the second pipeline communicates with the flasher and the compressor respectively, and the refrigerant in the first pipeline and the refrigerant in the second pipeline can exchange heat . 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 an air-injection enthalpy-increasing air-conditioning system and a control method thereof. 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 . During the operation of the air-injection enthalpy-increasing air-conditioning system, the compressor can be supplied with air by o...
