A refrigeration apparatus includes two sub passages which are branched from a main passage located between a condenser and an expansion part and which are connected to a compressor. On the sub passages are provided supercooling-use expansion parts, and supercooling-use heat exchangers for performing heat exchange between a refrigerant on an outlet side of the supercooling-use expansion part and a refrigerant of the main passage. Therefore, each time the refrigerant of the main passage passes through the two supercooling-use heat exchangers the degree of liquid supercooling of the refrigerant is increased.
