摘要： It is an object of the present invention to prevent a shortage of suction gas in a compressor by ensuring that surplus refrigerant does not occur in a refrigerant circuit and to suppress the occurrence of noise in the vicinity of a rotary type compressor. A refrigerating apparatus (1) is disposed with a compressor (21), a first heat exchanger (22), an expansion mechanism (23), a second heat exchanger (24) and a muffler (26). The compressor is a rotary type compressor that compresses a refrigerant. The first heat exchanger causes the refrigerant of a high temperature and a high pressure that has been compressed by the compressor to exchange heat with a first fluid. The expansion mechanism reduces the pressure of the refrigerant that has been condensed inside the first heat exchanger. The second heat exchanger causes the refrigerant whose pressure has been reduced by the expansion mechanism to exchange heat with a second fluid. The muffler is disposed between the second heat exchanger and the compressor and reduces the pulsation of the flow of the refrigerant.

摘要： An accumulator (40) is provided with: a vessel (20A) that separates a refrigerant into gas and liquid phases in the interior of the vessel; a plurality of pipes (21, 22) that extract the gas phase in the vessel (20A) to the outside of the vessel (20A); and brackets (41, 42) that hold together the plurality of pipes (21, 22) that extend in parallel inside the vessel (20A). The brackets (41, 42) are separated from the vessel (20A) and hold together respective sections of the plurality of pipes (21, 22) inside the vessel (20A).

摘要： A thermal management loop system may include an accumulator, an evaporator in fluid receiving communication with the accumulator, a condenser in fluid receiving communication with the evaporator, and a rotary separator in fluid receiving communication with the condenser. Gas exiting the rotary separator may recirculate back to the condenser and liquid exiting the rotary separator may flow to the accumulator. The thermal management loop system may be a dual-mode system and thus may be operable in a powered-pump mode or a passive-capillary mode.

摘要： A gas liquid separator (1A) includes: a sealed container (2) including an upper cover portion (21), a tubular portion (22), and a lower cover portion (23); and three pipes extending from the outside of the sealed container (2) to the inside thereof, that is, a first pipe (3A), a second pipe (3B), and a gas outlet pipe (4). A guide member (5) that forms an inflow space (11) between the guide member (5) and the upper cover portion (21) and forms a flow passage (15) for a two-layer flow F between the guide member (5) and the inner peripheral face of the tubular portion (22) is disposed in the sealed container (2). The first pipe (3A) and the second pipe (3B) are configured such that when one of the first pipe (3A) and the second pipe (3B) is used to introduce a gas-liquid two-phase fluid into the inflow space (11) from outside the sealed container (2), the other one is used to discharge a liquid in a liquid reservoir (13) from the sealed container (2) through a liquid outlet port (31 or 32) of the other one while forming a liquid surface at a level above the liquid outlet port (31 or 32).

摘要： In certain embodiments, a transcritical refrigeration system (100) provides refrigeration by circulating carbon dioxide (CO 2 ) refrigerant through the system (100). A flash tank (105) of the transcritical refrigeration system (100) is operable to supply the CO 2 refrigerant, in liquid form, to a low temperature refrigeration case (115a) and a medium temperature refrigeration case (115b). A low temperature compressor (120a) is operable to compress the CO 2 refrigerant discharged from the low temperature refrigeration case (115a). A medium temperature compressor (120b), a parallel compressor (120c), and an ejector are each operable to compress the CO 2 refrigerant discharged from the medium temperature refrigeration case (115b), the CO 2 refrigerant discharged from the low temperature compressor (120a), and/or CO 2 flash gas discharged from the flash tank (105). A gas cooler (130) is operable to cool the CO 2 refrigerant discharged from the medium temperature compressor (120b) and the parallel compressor (120c). A controller (100) is operable to dynamically adjust a pressure set point for the flash tank (105).

摘要： Methods, systems and apparatuses are described that are directed to on-site recovery and/or repurposing of refrigerant, where an original refrigerant is converted into a refrigerant different from the original refrigerant. The refrigerant different from the original refrigerant can have relatively lower global warming potential (GWP) than the original refrigerant. The recovery and/or repurposing can be implemented for example in a refrigeration circuit, such as for example in general cooling and/or heating applications, which may be embodied in a heating, venting, and air conditioning (HVAC) system and/or unit, in a transport refrigeration system and/or unit, as well as in commercial, residential and/or industrial cooling and/or heating applications.
