摘要： An ejector has an interior nozzle, an exterior nozzle, a suction part, a mixing part and a diffuser part. The interior nozzle and the exterior nozzle are arranged coaxially with each other. A driving fluid is supplied to the interior nozzle and/or the exterior nozzle. The suction part is arranged on an outer periphery of the exterior nozzle and sucks a suction fluid by a driving fluid jet ejected from the interior nozzle and/or the exterior nozzle. A mixing part mixes the driving fluid jet with the suction fluid, and supplies a mixture fluid. The diffuser part reduces a flow speed of the mixture fluid and ejects the mixture fluid outside. An outlet part of the interior nozzle is arranged at an upstream side of the ejector more than an outlet part of the exterior nozzle along the axial direction of the ejector.

摘要： A body part of a decompression device has a swirl space for swirling a refrigerant that flows from a refrigerant inlet, and a refrigerant outlet that is positioned on an extension line of a swirl center line of the refrigerant and functions as a throttle. Further, a passage cross-sectional area of the refrigerant inlet is configured to be smaller than a twelve-fold value of a passage cross-sectional size of the refrigerant outlet, such that a swirl speed of the refrigerant in the swirl space is increased so as to enable a decompression boiling of the refrigerant around the swirl center line. In such manner, a gas-liquid mixture phase refrigerant securely flows into the refrigerant outlet, and it restricts a fluctuation of a flow amount of the refrigerant flowing toward a downstream side without complicating a cycle structure.

摘要： A chiller system is provided including a vapor compression circuit consisting of a fluidly coupled compressor, condenser, expansion valve, and evaporator. A refrigerant circulates through the vapor compression circuit. The evaporator is a direct exchange heat exchanger. Refrigerant provided at an outlet of the evaporator is a two-phase mixture including liquid refrigerant and vapor refrigerant. The vapor refrigerant comprises less than or equal to 85% of the two-phase mixture. A refrigerant to refrigerant heat exchanger is fluidly coupled to the circuit. The refrigerant to refrigerant heat exchanger is configured to convert the vapor refrigerant provided at the outlet of the evaporator into a superheated vapor.

摘要： An evaporator includes an inlet side space of a leeward side upper tank into which a refrigerant flows from a refrigerant inlet port, and an inlet side turn path that is formed of a group of tubes and connected to the inlet side space. A ratio of a total passage cross-sectional area AT1 of the group of tubes forming the inlet side turn path to an inlet passage cross-sectional area Ain of the refrigerant inlet port is set at 3.5 or less, and a ratio of a longitudinal direction length Lg1 of the inlet side space to an inlet equivalent diameter Din of the refrigerant inlet port is set at 25 or less. Further, a Reynolds number Re of the refrigerant that has flowed into the inlet side turn path is set at 1800 or more.

摘要： A system (170; 300; 400) comprising a compressor (22). A heat rejection heat exchanger (30; 420) is coupled to the compressor to receive refrigerant compressed by the compressor. A separator (180) has: a vessel (181); an inlet (50) coupled to the heat rejection heat exchanger to receive refrigerant; a first outlet (54) in communication with a headspace of the vessel; and a second outlet (52, 52′) in communication with a lower portion of the vessel. The system has a heat exchanger (182; 220; 220′; 220″; 220′″) for transferring heat from refrigerant passing from a heat rejection heat exchanger to liquid refrigerant in the separator.

摘要： A refrigeration cycle device includes: a compressor that constitutes a refrigeration cycle and compresses a supplied refrigerant; a refrigerant-retaining container that retains the refrigerant into which lubricating oil for the compressor is mixed, and which separates the gas refrigerant from the liquid refrigerant, and sends out the gas refrigerant to the compressor; a refrigerant conveying pump that conveys a fluid mixture including the liquid refrigerant and the lubricating oil retained in the refrigerant-retaining container; and an internal heat exchanger that changes the liquid refrigerant conveyed out from the refrigerant-retaining container by the refrigerant conveying pump to the gas refrigerant, and provides the compressor with the gas refrigerant together with the lubricating oil. Since the refrigerant conveying pump conveys the fluid mixture containing the liquid refrigerant and the lubricating oil retained in a refrigerant-retaining container, stable operation is possible.
