摘要：
In a two-stage compression refrigeration cycle device, a low-pressure side compression mechanism and a high-pressure side compression mechanism are intermittently operated to control such that the temperature of air blown into a freezer approaches a target temperature. Under the control, the high-pressure side compression mechanism is first stopped, and then the low-pressure side compression mechanism is stopped. Further, when a reference time has elapsed after driving the high-pressure side compression mechanism, then the low-pressure side compression mechanism is driven. The refrigeration cycle device can reduce a high-pressure side pressure difference upon driving the high-pressure side compression mechanism, and can also reduce a low-pressure side pressure difference upon driving the low-pressure side compression mechanism, thereby protecting both compression mechanisms.
摘要（中）：
在两级压缩式制冷循环装置中，间歇地操作低压侧压缩机构和高压侧压缩机构，以控制吹入冷冻机的空气的温度接近目标温度。 在该控制下，首先停止高压侧压缩机构，然后停止低压侧压缩机构。 此外，当在驱动高压侧压缩机构之后经过基准时间时，驱动低压侧压缩机构。 制冷循环装置能够在驱动高压侧压缩机构时降低高压侧压力差，并且也可以在驱动低压侧压缩机构时降低低压侧压力差，从而保护压缩机构。
