<P>PROBLEM TO BE SOLVED: To provide a refrigerating device capable of identifying factors of an inside temperature rise of the refrigerating device. <P>SOLUTION: The refrigerating device includes a refrigerant circuit configured by connecting: a compressor 11 by which a refrigerant is compressed to be discharged; a condenser 12 in which the refrigerant is condensed by exchanging heat; a throttling device 21 for decompressing the condensation refrigerant; and an evaporator 22 for exchanging heat between the condensation refrigerant and air to evaporate the refrigerant by piping. The refrigerating device also includes: an inside temperature detecting means 102 for detecting an inside temperature of the refrigerator 100, which is in a space of objects to be cooled; an outside temperature detecting means 101 for detecting a temperature outside that space on an outside wall side of the refrigerator; and a control device 30 for calculating a cooling capacity, and a cooling load which is caused by intrusion heat transmitted from the outside wall side to the inside of the refrigerator based on temperatures detected by the inside temperature detecting means 102 and the outside temperature detecting means 101, and identifying the factors of the inside temperature rise occurred in the refrigerator 100 based on the magnitude of a steady cooling load including the intrusion heat. <P>COPYRIGHT: (C)2013,JPO&INPIT |
