PURPOSE:To carry out sophisticated temperature control which eliminates the nonuniformity of temperature distribution in a refrigerator capable of storing foodstuffs in a refrigerated state. CONSTITUTION:An arithmetic operation means 32, which computes the degree of temperature rise, is installed to a refrigerated chamber so as to calculate the degree of temperature rise inside the refrigerator. In addition, there is installed an open air temperature detection means 31 so as to detect the temperature of open air. A fuzzy inference processor 34 carries out fuzzy arithmetic operation based on a control rule picked up from a first memory 33 with the temperature rise degree, the open air temperature, thereby determining an increase range of a setting rotary speed of a fan 14. Based on the data stated above, a setting rotary speed arithmetic operation means 35 adjusts the setting rotary speed, thereby controlling the fan. Similar control functions are carried out in a cold storage chamber as well. |
