REFRIGERATING DEVICE

WIPO Patent Application WO/2015/159326

A1

The purpose of the invention is to provide a refrigerating device that can quickly restore the temperature in a chamber to a target chamber temperature when a sudden change in temperature has occurred in the chamber and that is able to keep excessive control and unnecessary cooling to a minimum when the chamber temperature is returning to the target chamber temperature. This refrigerating device determines a target evaporation temperature with a target evaporation temperature setting means (52), using the detected chamber temperature and the amount of change in the chamber temperature calculated by a chamber temperature change calculating means (54) from the chamber temperature. When the chamber temperature is higher than a set value, the degree by which the target evaporation temperature is reduced in the determination is made successively smaller in the order of: when the change in the chamber temperature is positive and large; when the change is positive and small; and when the change is negative. Moreover, when the chamber temperature is lower than the set value, the degree by which the target evaporation temperature is increased is made successively smaller in the order of: when the change in the chamber temperature is negative and small; when the change is negative and large; and when the change is positive.
