AIR CONDITIONER

PROBLEM TO BE SOLVED: To reduce the flowing noise of the refrigerant generated in a dehumidifying throttling device during the dehumidification while deterioration of the performance in the cooling operation or heating operation by forming a sub refrigerant flow passage in which the refrigerant is distributed to the dehumidifying throttling device is formed on a valve disk in the vertical direction to provide the gas-liquid separating function of the refrigerant flow. SOLUTION: When a solenoid coil 20 is energized during the dehumidification, a plunger 25 having a valve disk 24 is moved in a valve body 23 by the attraction of a suction element 21 to close a main refrigerant flow passage 27. The refrigerant passes through the high pressure side refrigerant flow passage 31 from a dehumidification control valve inlet piping 32, flows into a sub refrigerant flow passage 28 and a sub refrigerant flow passage 29, enters a sub refrigerant flow passage 30, passes through a low pressure side refrigerant flow passage 33, and flows out of an outlet piping 34. When the sub refrigerant flow passage 30 is vertically opened in the valve disk 24 and the refrigerant flows into the dehumidification control valve in a gas-liquid two-phase flow, the gas refrigerant and the liquid refrigerant flows in an upper layer and a lower layer except the vertical piping respectively, and the gas refrigerant flows in the sub refrigerant flow passage 28 and the liquid refrigerant flows in the sub refrigerant flow passage 29 in a gas-liquid separated manner.
