摘要： An object is to provide a freezing device in which a safely-treatable incombustible mixed refrigerant can be used and which can realize an extremely low temperature of −85° C. or less in chamber by a simple structure. The freezing device comprises a single refrigerant circuit in which the refrigerant discharged from a compressor is condensed and thereafter evaporated to exert a cooling function and which allows heat exchange between the evaporated refrigerant and the condensed refrigerant, wherein there is introduced into the refrigerant circuit a non-azeotropic mixed refrigerant containing R245fa, R600, R23 and R14; a non-azeotropic mixed refrigerant containing R245fa, R600, R116 and R14; a non-azeotropic mixed refrigerant containing R245fa, R600, R508A and R14; or a non-azeotropic mixed refrigerant containing R245fa, R600, R508B and R14.
