The evaporator has a refrigerant outlet coupled to the refrigerant suction port of the ejector. Furthermore, a refrigerant radiating portion is provided for radiating heat of refrigerant while the decompression portion decompresses and expands refrigerant. For example, the refrigerant radiating portion is provided in an inner heat exchanger.

    摘要: A refrigerant cycle device having an ejector includes a first evaporator for evaporating refrigerant flowing out of the ejector, a first passage portion for guiding refrigerant to a refrigerant suction port of the ejector, a throttle unit located in the first passage portion, a second evaporator located in the first passage portion downstream of the throttle unit, a bypass passage portion for guiding hot gas refrigerant from a compressor into the second evaporator, a bypass opening and closing unit provided in the bypass passage portion. Furthermore, a second passage portion is branched from the bypass passage portion downstream of the bypass opening and closing unit, and a flow control unit is provided in the second passage portion to prevent a flow of refrigerant from the first evaporator to the second evaporator through the second passage portion. Therefore, defrosting of both the first and second evaporators can be suitably performed.

    摘要: A mixed refrigerant including a plurality of component refrigerants circulates in a refrigeration cycle device. An expansion valve includes a power element. A filled fluid filled in the power element is one component refrigerant in the plurality of component refrigerants. A slope of a saturated vapor pressure curve of the filled fluid is larger than the slope of the saturated vapor pressure curve SV0 of the mixed refrigerant. Thereby, an opening degree of the expansion valve can be prevented from exceeding in a low-temperature region, and the opening degree corresponding to a load can be obtained in a high-temperature region.

    摘要: An ejector device includes a nozzle having an inner wall surface defining a circular cross-sectional fluid passage extending from an inlet to a jet port. Furthermore, the fluid passage has a throat portion at a position between the inlet and the jet port, and a passage expanding portion in which the cross-sectional area of the fluid passage is enlarged from the throat portion as toward downstream. The passage expanding portion includes a middle portion in which the inner wall surface is expanded in a fluid flow direction by a first expanding angle, and an outlet portion from a downstream end of the middle portion to the jet port, in which the inner wall surface is expanded in the fluid flow direction by a second expanding angle that is larger than the first expanding angle. The ejector device can be suitably used for a refrigeration cycle apparatus.

The vapor compression refrigerating cycle apparatus is configured such that refrigerant pressure (P0) at an inlet of the first decompressing device, refrigerant pressure (P) at an inlet of a nozzle portion of the ejector, refrigerant pressure (P2) at an outlet of the nozzle portion satisfy a pressure relationship of 0.1×(P0−P2)≦(P0−P)≦0.6×(P0−P2). Alternative to or in addition to the pressure relationship, the vapor compression refrigerating cycle apparatus is configured such that a dryness of refrigerant at the inlet of the nozzle portion is in a range between 0.003 and 0.14.
