<P>PROBLEM TO BE SOLVED: To provide a container refrigeration unit allowing a temperature of air to be blown into a chamber to be properly controlled. <P>SOLUTION: The container refrigeration unit (10) includes a refrigerant circuit (16) and a reheater (32), and performs dehumidifying operation, which heats, in the reheater (32), the air sucked from inside of the chamber of a container (C) and cooled and dehumidified in an evaporator (25). The container refrigeration unit includes: a suction temperature sensor (33) detecting the temperature of the air sucked into the evaporator (25); a blow-off temperature sensor (34) detecting the temperature of the air heated by the reheater (32); a temperature control unit (36) controlling the dehumidification operation on the basis of the value of the detected temperature of the blow-off temperature sensor (34); and a temperature correction unit (37) correcting a value of the detected temperature of the blow-off temperature sensor (34) to be lower than the detected temperature of the suction temperature sensor (33) when the detected temperature of the suction temperature sensor (33) lowers below the detected temperature of the blow-off temperature sensor (34) in the dehumidification operation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
