<P>PROBLEM TO BE SOLVED: To provide a refrigerating device capable of cooling air and generating ice at the same time with a simple constitution and further easily utilizing cold heat of the generated ice for cooling air. <P>SOLUTION: A refrigerant circuit (11) is equipped with flow path switching mechanisms (94, 107, 111) for switching flow paths of refrigerant so as to carry out ice heat storing cooling operation in which the refrigerant of a using side heat exchangers (62, 72, 82) evaporate and cool the air and at the same time the refrigerant of an ice heat storing heat exchanger (106) evaporates and generates ice and ice using cooling operation in which the refrigerant radiates heat to ice around the ice heat storing heat exchanger (106) and the refrigerant after radiating heat evaporates in the using side heat exchangers (62, 72, 82), and evaporation temperature controlling mechanisms (104, 105) making the evaporation temperature of the refrigerant of the ice heat storing heat exchanger (106) lower than the evaporating temperature of the refrigerant of the using side heat exchanger (62, 72, 82) during the ice heat storing cooling operation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
