<P>PROBLEM TO BE SOLVED: To obtain a refrigerating apparatus in which a refrigeration capability and an energy saving performance of the entire refrigerating apparatus are improved by making a heat exchange capability proper in an air-cooled condenser of a high-temperature side cycle and an air-cooled intermediate cooler of a low-temperature side cycle. <P>SOLUTION: A refrigerating apparatus includes a high-temperature side cycle device 10 which forms a high-temperature side circulation circuit, a low-temperature side cycle device 20 which has an air-cooled intermediate cooler and forms a low-temperature side circulation circuit, a cascade condenser 30 which is comprised of a high-temperature side evaporator 14 and a low-temperature side condenser 22 and performs heat exchange between a high-temperature side refrigerant and a low-temperature side refrigerant, an air blower 40 for blowing air into a high-temperature side air-cooled condenser 12 and the air-cooled intermediate cooler 25, and a control device 60 which determines a final output of the air blower 40 on the basis of a first air blower output result determined based on a physical quantity related to the high-temperature side circulation circuit and a second air blower output result determined based on a physical quantity related to the low-temperature side circulation circuit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
