Abstract
A swirl space forming member that forms a swirl space in which a refrigerant flowing into a nozzle portion of an ejector swirls around an axis of the nozzle portion. In this way, even when the refrigerant flowing out of a first evaporator is a gas-phase refrigerant, pressure of the refrigerant on a swirling center axis side in the swirl space is reduced to be able to start condensation by swirling the refrigerant, and a gas-liquid two-phase refrigerant in which a condensation nucleus is generated can flow into the nozzle portion. Thus, occurrence of a condensation delay in the refrigerant in the nozzle portion can be restricted.
