<P>PROBLEM TO BE SOLVED: To detect the clogging of refrigerant in an accumulator (33) even without detecting the pressure of refrigerant between the accumulator and a compressor. <P>SOLUTION: A refrigeration device includes: a first determination part (1) for determining whether an operation current value of a compressor (18) is lower than a first threshold; a second determination part (2) for determining whether a pressure value of refrigerant flowing through an inlet pipe (17) of the accumulator (33) is more than a second threshold; and the third determination part (3) for determining, based on the determination results by the first determination part (1) and the second determination part (2), whether the accumulator (33) is clogged with refrigerant. <P>COPYRIGHT: (C)2013,JPO&INPIT |
