Title:
二段昇圧式冷凍サイクル
Document Type and Number:
Japanese Patent JP5287831
Kind Code:
B2
Abstract:
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.
