To provide a refrigeration device capable of effectively utilizing cold heat energy by preventing wasteful release of a low-temperature gas used in freezing and cooling a cooled object, to the atmospheric air.
The refrigeration device comprises a circulation flow channel L1 including a compressor 11, a cooler 12, a heat exchanger 13, an expander 14 and a freezing chamber 15, to allow a refrigerant gas to flow through the compressor 11, the cooler 12, the heat exchanger 13, the expander 14 and the freezing chamber 15, and return to the compressor 11 through the heat exchanger 13 again, and a liquefied refrigerant gas supply flow channel L2 for guiding a liquefied refrigerant gas from a liquefied refrigerant gas supply source 16 to a supply sprayer 17, and injecting the liquefied refrigerant gas from the supply sprayer 17 into the freezing chamber 15.
