Title:
REFRIGERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/032794
Kind Code:
A1
Abstract:
A refrigerating device comprising: a first refrigerant circuit in which a first compressor, a first condenser, a first pressure reducer, and a first evaporator are interconnected annularly by first refrigerant piping and which evaporates a refrigerant by the first evaporator after the refrigerant discharged from the first compressor to obtain a cooling action is condensed by the first condenser; a second refrigerant circuit in which a second compressor, a second condenser, a second pressure reducer, and a second evaporator are interconnected annularly by second refrigerant piping and which evaporates a refrigerant by the second evaporator after the refrigerant discharged from the second compressor to obtain a cooling action is condensed by the second condenser; a temperature sensor which detects the temperature in a low-temperature storage compartment in which the first evaporator and the second evaporator are arranged so as to simultaneously cool the inside of the low-temperature storage compartment; and a first control device which performs control so that the first compressor and the second compressor are both operated every time the temperature detected by the temperature sensor reaches a first temperature and so that the first compressor and the second compressor are operated alternately every time the temperature detected by the temperature sensor reaches a second temperature lower than the first temperature.
