Title:
REFRIGERATOR AND REFRIGERATION DEVICE
Document Type and Number:
Japanese Patent JP2015215160
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigerator and the like capable of saving energy while securing high reliability.SOLUTION: A refrigerator has at least a low stage-side compressor for compressing a refrigerant and discharging the same, an auxiliary radiator exchanging heat between the refrigerant discharged from the low stage-side compressor and ambient air for making the refrigerant radiate heat, a high stage-side compressor for compressing the refrigerant radiated by the auxiliary radiator and discharging the same, and a high stage-side radiator exchanging heat between the refrigerant discharged from the high stage-side compressor and the ambient air, and making the refrigerant radiate heat. Carbon dioxide is used as the refrigerant, and the high stage-side radiator and the auxiliary radiator are composed of an integrated radiator in which a radiation amount ratio as a ratio of a radiation amount of the refrigerant in the auxiliary radiator to the total radiation amount of the radiation amount of the refrigerant in the high stage-side radiator and the radiation amount of the refrigerant in the auxiliary radiator is 17% or less, the high stage-side radiator is positioned at a lower side with respect to the auxiliary radiator, and heat transfer fins are integrated.
