Refrigerating apparatus
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（中）：

冰箱回路（110）和冷冻回路（30）在制冷剂回路（20）中并联连接到室外回路（40），冷冻回路（130）和升压回路（140）串联连接 在冷冻回路（30）中。 升压电路（140）包括增压压缩机（141）和三通切换机构（142,160）。 在冷冻热交换器（131）的制冷运转时，在三通切换机构（142,160）中进行第一操作，使得在冷冻热交换器（131）中蒸发的制冷剂在增压压缩机141中被压缩， 并被吸入变容量压缩机（41）。 在冷冻热交换器（131）的除霜期间，在三通切换机构（142,160）中进行第二操作，使得在增压压缩机（141）中在制冷用热交换器（111）中蒸发的制冷剂被压缩， 供给到冷冻热交换器（131），然后被送回制冷用热交换器（111）。
