REFRIGERATING DEVICE AND REFRIGERATING DEVICE CONTROL METHOD

Title:

REFRIGERATING DEVICE AND REFRIGERATING DEVICE CONTROL METHOD

Document Type and Number:

WIPO Patent Application WO/2015/140873

Kind Code:

A1

Abstract:

A refrigerating device (1) comprises: a lower source side refrigeration cycle (10) that has a lower source side compressor (11), a lower source side condenser (12), a lower source side pressure reducing device, and a lower source side evaporator (14) and in which a lower source side refrigerant circulates; an upper source side refrigeration cycle (30) that has an upper source side compressor (31), an upper source side condenser (32), an upper source side pressure reducing device, and an upper source side evaporator (34) and in which an upper source side refrigerant circulates; a cascade condenser (40) by which heat is exchanged between the lower source side refrigerant of the lower source side condenser (12) and the upper source side refrigerant of the upper source side evaporator (34); and a control device (50). The lower source side refrigerant is a refrigerant that undergoes a disproportionation reaction, and the pressure of the lower source side refrigerant is maintained at a lower pressure than the pressure at which the lower source side refrigerant undergoes the disproportionation reaction.
