A refrigeration device includes: a refrigerant circuit in which a compressor, a condenser, a decompressor, and an evaporator are connected circularly in the stated order; and a regenerative refrigerator including a heat dissipation portion that compresses a working fluid enclosed in a chamber and dissipates heat produced by compression, and a heat absorption portion in which the working fluid compressed in the heat dissipation portion is expanded. A refrigerant in the condenser is cooled by heat exchange between the condenser and the heat absorption portion. |
