PROBLEM TO BE SOLVED: To provide a relatively inexpensive large refrigerator for business use, maintaining high capability by suppressing the rise of a compression ratio and making up for low volume capability while using high boiling point refrigerant having refrigerant theoretical efficiency and compressor effective efficiency. SOLUTION: The refrigerator using the high boiling point refrigerant comprises an inverter compressor 71, a constant speed compressor 72, a capillary A24 and a capillary B26 as independent pressure reducing means, and independent cooling system tubes. An evaporator 21 and a condenser 22 are shared with each other. Thus, the relatively inexpensive refrigerator maintains high capability by making up for low volume capability while using the high boiling point refrigerant. COPYRIGHT: (C)2005,JPO&NCIPI
