摘要： Provided is a refrigeration circuit wherein surplus refrigerant created during an air-cooling operation can be accommodated when the capacity of an outdoor heat exchanger is less than the capacity of an indoor heat exchanger. In a refrigeration circuit (11), an indoor heat exchanger (51) is a cross-fin type heat exchanger and an outdoor heat exchanger (25) is a stacked heat exchanger. A refrigerant storage tank (27) is provided between the outdoor heat exchanger (25) and an expansion valve (29). Because the capacity of the outdoor heat exchanger (25) is less than the capacity of the indoor heat exchanger (51), the surplus refrigerant is present during the air-cooling operation, but because the surplus refrigerant is accommodated in the refrigerant storage tank (27) in this refrigeration circuit (11), the surplus refrigerant is prevented from hindering refrigeration control.
摘要翻译：本发明提供一种制冷回路，在室外热交换器的容量小于室内热交换器的容量的情况下，能够适应在制冷运转时产生的剩余制冷剂。在制冷回路11中，室内热交换器51是交叉翅片式热交换器，室外热交换器25是层叠式热交换器。在室外热交换器25与膨胀阀29之间设有制冷剂贮存箱27。由于室外热交换器25的容量小于室内热交换器51的容量，因此在制冷运转时存在剩余的制冷剂，但是由于剩余的制冷剂容纳在制冷剂贮存箱内在该制冷剂回路11中，能够防止剩余制冷剂妨碍制冷控制。
