PURPOSE:To suppress the power consumption of a compressor and to enhance reliability by starting a fan or the fan and the compressor in synchronous relation to the opening of a damper only when the temp. of a chamber controlled by the damper is set on a low temp. side. CONSTITUTION:Since a compressor (7) and a fan (9) are controlled in perfectly synchronous relationship, even when a damper (14) is opened (time Tc3 - Tc4) during the stoppage of the compressor (7) and the fan (9) like time Tf2 - Tf3, a chilled chamber (4) is not cooled during the stoppage of the compressor (7) and, therefore, the steady deviation of the temp. of the chilled chamber (4) from a set value becomes large. However, since the fan (9) is not rotated during the stoppage of the compressor 7 and the temp. in a freezing chamber (2) becomes hard to rise, the time from the stop of the compressor (7) to the restart thereof becomes long (during time Tf2 - Tf3) and the operation factors of the compressor (7) and the fan (9) can be lowered. |
