    摘要: A refrigerator circuit (110) and a freezing circuit (30) are connected to an outdoor circuit (40) in parallel in a refrigerant circuit (20), and a freezer circuit (130) and a booster circuit (140) are connected in series in the freezing circuit (30). The booster circuit (140) includes a booster compressor (141) and three-way switching mechanisms (142, 160). During cooling operation of a freezing heat exchanger (131), first operation is performed in the three-way switching mechanisms (142, 160) so that the refrigerant evaporated in the freezing heat exchanger (131) is compressed in the booster compressor (141) and is sucked into a variable capacity compressor (41). During defrosting of the freezing heat exchanger (131), second operation is performed in the three-way switching mechanisms (142, 160) so that the refrigerant evaporated in the refrigeration heat exchanger (111) is compressed in the booster compressor (141), is supplied to the freezing heat exchanger (131), and then, is sent back to the refrigeration heat exchanger (111).

    摘要: A refrigeration apparatus (1) is disclosed which is provided with multiple systems of utilization-side heat exchangers (20, 30, 40) and in which liquid-side interunit piping lines (53, 54, 55) are combined into a single liquid-side interunit piping line in multiple systems of liquid lines. When the refrigeration apparatus (1) provides space heating of 100% heat recovery without the use of an outdoor heat exchanger (15), the flow of refrigerant in a refrigerant circuit (50) is stabilized even when the temperature of outside air is low, thereby preventing the capacity to provide refrigeration from decreasing. In addition, in order to prevent shutdown of the refrigeration apparatus (1) due to malfunction, a liquid refrigerant inflow passageway (66) is connected to a heat source-side liquid pipe (62) of an outdoor unit (10), the heat source-side liquid pipe (62) being connected to an integrated liquid pipe (53) of the liquid-side interunit piping lines (53, 54, 55), and to an inlet port of the a receiver (17), and a switch valve (SV1) capable of being on-off controlled is disposed in the liquid refrigerant inflow passageway (66).

    摘要: In a refrigerant circuit (20), an air conditioning unit (12), a cold-storage showcase (13), and a freeze-storage showcase (14) are connected in parallel to an outdoor unit (11). When placing an indoor heat exchanger (71) of the air conditioning unit (12) in the thermo-off state, a degree-of-opening control means (101) provides control so that an indoor expansion valve (72) is placed in the fully closed state. Thereafter, the degree-of-opening control means (101) detects the accumulated amount of refrigerant within the indoor heat exchanger (71) and then adjusts the degree of opening of the indoor expansion valve (72) depending on the refrigerant amount detected.

    摘要: A subcooling unit (200) includes a refrigerant passage (205) connected to liquid side communication pipes (21, 22) of a refrigerating apparatus (10). When a subcooling compressor (221) is operated, subcooling refrigerant circulates in a subcooling refrigerant circuit (220) to perform a refrigeration cycle, thereby cooling refrigerant of the refrigerating apparatus (10) which flows in the refrigerant passage (205). A controller (240) of the subcooling unit (200) receives the detection value of an outside air temperature sensor (231) or a refrigerant temperature sensor (236). The controller (240) controls the operation of the subcooling compressor (221) with the use of only information obtainable within the subcooling unit (200).

    摘要: A subcooling unit (200) includes a refrigerant passage (205) connected to liquid side communication pipes (21, 22) of a refrigerating apparatus (10). When a subcooling compressor (221) is operated, subcooling refrigerant circulates in the subcooling refrigerant circuit (220) to perform a refrigeration cycle, thereby cooling refrigerant of the refrigerating apparatus (10) which flows in the refrigerant passage (205). A controller (240) of the subcooling unit (200) receives the detection value of a suction pressure sensor (234) and a refrigerant temperature sensor (236). The controller (240) utilizes input signals from the sensors (234, 236) to control driving operation of the subcooling compressor (221) on the basis of information obtained within the subcooling unit (200). Thus, the operation of the subcooling compressor (221) can be controlled without sending and receiving a singal to and from the refrigerating apparatus (10) to which the subcooling unit (200) is incorporated.
