Abstract

There is provided a refrigerant distributor that does not increase a size of an apparatus configuration and cost even when constituting a large air conditioner, and can stably distribute a refrigerant in a two-phase state in a wide flow rate range. In a refrigerant in a gas-liquid two-phase state flowing from an upper end 11a of a refrigerant tube 11 into a body 13, a liquid phase of the refrigerant having flown along an inner peripheral surface of the refrigerant tube 11 collides with an inner peripheral ring 32 of a gas-liquid separation ring 30 and returns a liquid film flow downward. A gas phase of the refrigerant mainly flowing through a center in the refrigerant tube 11 passes through a central opening 34 on an inner peripheral side of the inner peripheral ring 32 and reaches above the gas-liquid separation ring 30. Then, the liquid phase of the refrigerant is mainly sucked up from an opening 23 opening on an inner peripheral side of a lower end of a sleeve 20, and the gas phase of the refrigerant is sucked from a through hole 24 opening at an upper portion of the sleeve 20 into each capillary tube 12, and thus the refrigerant with a uniform mixing ratio between the liquid phase and the gas phase is fed into each capillary tube 12.
