    摘要: A thermal storage container (70) is coupled to a pump (80) for circulating cooled liquid from the thermal storage container (70) in at least one of two circuits. One circuit includes a heat exchanger (100) coupled to the fresh food evaporator (49) for assisting in cooling the fresh food section of the refrigerator or for chilling the liquid. Another circuit includes a sub-cooler (96) between the compressor and condenser for cooling the hot gas output from the compressor before entering the condenser, thereby increasing the efficiency of the system. A three-way valve (90) is coupled from the output pump to couple the stored coolant selectively to one or the other or both of the coolant circuits.

    摘要: Provided is a refrigeration device that makes it possible to effectively eliminate problems caused by dryicing of carbon dioxide. This refrigeration device (R) is provided with a refrigerant circuit in which a refrigerant discharged from a compressor (2) is caused to condense, then depressurized in a capillary tube (28) and caused to evaporate in an evaporator (3) to obtain a refrigeration effect. A mixed refrigerant containing a first refrigerant having a boiling point in an extremely low-temperature region of -89.0°C to -78.1°C and carbon dioxide (R744) are sealed in as a refrigerant in the refrigerant circuit. A heater for heating at least a part of an intake pipe (32) channeling a refrigerant returning from the evaporator to the compressor is provided.

    摘要: There is disclosed a refrigerating apparatus which can more efficiently cool the inside of a chamber to an ultralow temperature. In a refrigerating apparatus R1 which condenses a refrigerant discharged from a compressor 14, reduces a pressure of the refrigerant by a capillary tube 18 and evaporates the refrigerant by an evaporator 13 to exert a cooling function, the capillary tube 18 is passed through a suction piping line 32 through which the refrigerant returning from the evaporator 13 to the compressor 14 flows, to constitute a double tube structure. Furthermore, the suction piping line 32 (a piping line 32A) formed in the double tube structure by passing the capillary tube 18 therethrough is surrounded with an insulating material 35.

    摘要: A refrigeration circuit (3) for household appliances comprises a compressor (4) suitable for compressing a predetermined cooling fluid and for allowing circulation thereof within said circuit (3), a first heat exchanger (5) or condenser in fluid communication with the compressor (4) for allowing cooling and the consequent condensation of the cooling fluid going therethrough, and a second heat exchanger (7) or evaporator in fluid communication with the first exchanger (5) through a circuit with a special device (6) suitable for decreasing the pressure of the cooling fluid and acting at a space (2) to be cooled (normally inside the refrigerator). The second exchanger (7) allows the cooling fluid to evaporate, by heat absorption, thus cooling the space (2) and returning through the tubing (17) to the compressor (4). The cooling fluid circulates from the compressor (4) towards the first exchanger (5), from the latter towards the second exchanger (7), then returning to the compressor (4) for a subsequent cycle. At least one of the heat exchangers (5, 7) comprises a plastic tubing (9), at least one portion whereof exhibits such a corrugated profile as to impart flexibility thereto and/or increase the thermal exchange surface. The tubing in section exhibits a structural layer (100) of plastic material and a layer (101) comprising a film of metal material adapted to constitute a barrier against humidity and gases in general, such shaped as to maintain the tube flexibility.
