Description

[0002] One -way valve is that fluid can only flow along the water inlet, and the water outlet medium cannot backflow, commonly known as one -way valve. One -way valve is also called check valve or non -return valve, in air conditioning equipment, because the refrigerant medium needs to flow in a certain direction, so one -way valve will be used.

[0003] In the air conditioning system, the three -way one -way valve shows significant advantages compared with the ordinary one -way valve. From the fluid control point of view, the unique structure design of three -way one -way valve can more flexibly adjust the refrigerant flow direction, and in complex refrigeration cycle working conditions, it can realize the refrigerant distribution and switching of multiple paths, which greatly improves the adaptability and stability of system operation. Ordinary one -way valve can only realize single direction control, and the functional diversity is far less than three -way form.

[0004] However, the three -way one -way valve used in the traditional air conditioner has problems such as right angle bending, which has a negative impact on the system performance. In the refrigerant circulation process, freon as the key refrigeration working medium, when flowing through such one -way valve, due to the increase of local resistance at the right angle bending, obvious throttling effect will be caused, which leads to the significant reduction of freon flow rate, especially in the area where the two sides converge into the center pipe, even the left and right flow channels may collide, which further affects the flow rate. According to the principle of fluid mechanics, the reduction of flow rate directly affects the heat exchange efficiency of refrigerant, and then reduces the refrigerating capacity of air conditioning system, finally leads to the great discount of refrigeration efficiency, which is difficult to meet the demand of high -efficient refrigeration.
