Abstract

The invention relates to a reversing valve, in particular to a coolant circulating system having an integrated reversing valve. The integrated reversing valve is connected with a compressor, a gas coolant separator, an expansion valve, a condenser and an evaporator in the coolant circulating system through a pipeline, and consists of a main reversing valve and an electromagnetic reversing valve, wherein the main reversing valve comprises a hollow valve body and a valve core arranged in the valve body; cavities are arranged between two ends of the valve body and the valve core; the valve core can make displacement along an axial direction of the valve body, and is provided with coolant channels; when the valve core moves to a left end or a right end, ports of the coolant channels align with joints arranged on the valve body; the two ends of the valve body are also provided with an A end part joint and a B end part joint which are connected with the electromagnetic reversing valve through the pipeline; and the electromagnetic reversing valve is used for driving the main reversing valve to reverse. In the coolant circulating system having the integrated reversing valve, a four-way reversing valve and a vapor-liquid separation integrated reversing valve in the prior art are designed into the integrated reversing valve, so that the structure of the reversing valve is compact.

Description

technical field [0001] The invention relates to a reversing valve, in particular to a refrigerant circulation system equipped with an integrated reversing valve. Background technique [0002] The reversing valve is used to change the path of fluid flow. The reversing valve can change the circulation direction of the circulating gas or liquid. In the refrigerant circulation system of the existing air conditioner, a four-way reversing valve is generally used to change the circulation direction of the refrigerant. , to realize the cooling or heating conversion of the air conditioner. In the air conditioner, in order to improve the cooling or heating efficiency of the air conditioner, it is necessary to install a gaseous refrigerant separator in the refrigerant circulation system, which can separate the gaseous refrigerant from the liquid refrigerant, and the separated liquid refrigerant continues to enter the refrigeration or Heating cycle, and the gaseous refrigerant will ret...
