摘要：
The pull-down cooling characteristic representing the mode of variation with time of the target temperature fall in a pull-down cooling range is stored as data in a storage unit (49). If this characteristic is represented by, e.g., a straight line xp of a linear function, the target in-storage temperature fall rate is a constant Ap independently of the in-storage temperature. When pull-down control is started, the in-storage temperature is detected every predetermined sampling time. The actual temperature fall rate Sp is calculated from the detected in-storage temperature and compared with the target value Ap read out of the storage unit (49). If the calculated value Sp is the target value Ap or less, the rotational speed of an inverter compressor (32) is increased through an inverter circuit (50); contrarily if the calculated value Sp is above the target value Ap, the rotational speed of the compressor (32) is decreased. While repeating this, pull-down cooling is performed following the straight line xp.
