REFRIGERATION DEVICE

摘要

Provided is a refrigeration device that makes it possible to effectively eliminate problems caused by dryicing of carbon dioxide. This refrigeration device (R) is provided with a refrigerant circuit in which a refrigerant discharged from a compressor (2) is caused to condense, then depressurized in a capillary tube (28) and caused to evaporate in an evaporator (3) to obtain a refrigeration effect. A mixed refrigerant containing a first refrigerant having a boiling point in an extremely low-temperature region of -89.0°C to -78.1°C and carbon dioxide (R744) are sealed in as a refrigerant in the refrigerant circuit. A heater for heating at least a part of an intake pipe (32) channeling a refrigerant returning from the evaporator to the compressor is provided.
