Abstract: A refrigeration cycle apparatus includes an evaporator, a first compressor, an intercooler, a second compressor, a condenser, and a refrigerant liquid supply passage. The intercooler stores refrigerant liquid and also cools refrigerant vapor compressed by the first compressor and expels it. The second compressor sucks in the refrigerant vapor expelled from the intercooler and compresses it. The intercooler includes a container, an intercooling passage, and a pump. The container contains a vapor space and stores refrigerant liquid. The intercooling passage is a passage in which a part of the refrigerant liquid stored in the container flows and that supplies the part of the refrigerant liquid to the vapor space. The pump pumps a part of the refrigerant liquid stored in the container to the vapor space.

Abstract: An ejector includes a first nozzle, a second nozzle, an atomization mechanism, and a mixer. A working fluid in a liquid phase is supplied to the first nozzle as a drive flow. A working fluid in a gas phase is sucked into the second nozzle. The atomization mechanism is disposed at an end of the first nozzle and atomizes the working fluid in a liquid phase while maintaining the liquid phase. The mixer generates a fluid mixture by mixing the atomized working fluid generated by the atomization mechanism and the working fluid in a gas phase sucked into the second nozzle. The atomization mechanism includes an ejection section that generates a jet of the working fluid in a liquid phase and a collision surface with which the jet from the ejection section collides. The collision surface is inclined with respect to a direction in which the jet flows.

Abstract: A refrigeration apparatus includes a container such as an evaporator for holding refrigerant, and a compressor for compressing refrigerant vapor. The compressed vapor is returned to the container, and stored as liquid. The liquid refrigerant is withdrawn from the container and then returned to the container via a first path through a heat exchanger for cooling a space, or a second path that does not pass through the heat exchanger. Upon returning to the container, the liquid refrigerant is at least partly evaporated due to the reduced pressure in the container caused by the operation of the compressor, and the container is cooled by the latent heat of evaporation. Thus, the container can act as a cold storage unit. The cold storage effect is increased when the refrigerant is returned to the container via the second path.

Abstract: An ejector includes an atomization mechanism that is disposed at an end of a first nozzle and that atomizes a working fluid in a liquid phase while maintaining the liquid phase. The atomization mechanism includes an orifice and a collision plate. When the collision plate is orthographically projected onto a projection plane, in a projection of the collision plate, at least one point on a contour of the collision surface is disposed closer to a reference point than a second reference line, which is a line including the collision end point and perpendicular to the first reference line.

Abstract: It is aimed to reduce the size of heat exchange tubes and also to reduce pressure loss of a fluid flowing in an external flow path formed between adjacent heat exchange tubes. A first projecting portion 41 and a second projecting portion 42 of a first heat exchange tube 2A are joined to portions around an inlet 3C and outlet 3D of a second heat exchange tube 2B. A first flow path forming portion 61, a second flow path forming portion 62, and a third flow path forming portion 63 of an internal flow path 3 of each of the first heat exchange tube 2A and the second heat exchange tube 2B face a first thin portion 21A and a second thin portion 21B of the second heat exchange tube 2B or the first heat exchange tube 2A across an external flow path 4. The first flow path forming portions 61, the second flow path forming portions 62, and the third flow path forming portions 63 of the first heat exchange tube 2A and the second heat exchange tube 2B are arranged in a staggered pattern in a width direction of the heat exchange tubes 2.
