PURPOSE:To perform delicate temperature controls of a refrigerator with a freezer where food is frozen and stored, and solve such a problem that optimum control can not be performed when food is loaded full or fast cooling is required because of unexpected visitors in the summer season, for example. CONSTITUTION:An ambient temperature arithmetic device 29 is provided to calculate the change degree of the ambient temperature of a freezing compartment from the compartment inside temperature, etc. A thermal load arithmetic device 31 is provided to calculate the thermal load amount of food on each shelf in the freezing compartment from the temperature of each shelf, etc. A fuzzy reasoning processor 33 performs fuzzy reasoning according to the change degree of ambient temperature, etc., and a control rule taken out from a memory 32. A damper controller 34 controls the opening degree of dampers provided on shelves according to the calculated result, and a fan motor controller 35 drives a fan. |
