Abstract

PROBLEM TO BE SOLVED: To solve the problem that the power consumption of the conventional refrigerator increases due to defrosting operation, because a defrosting heater is energized until defrosting is completed immediately after the defrosting operation is started. SOLUTION: A freezer/refrigerator is constituted of at least two or more rooms of a cold storage room, a refrigerating room, etc., and sends cold air cooled by means of a cooler to the rooms through cold air discharging air courses by means of a cold air forcibly circulating blower. In the air courses, motor-driven dampers for temperature adjustment are respectively provided toward the rooms. At the time of performing the defrosting operation, the temperature of the cooler is raised by bringing back the cold air in the cold storage room maintained at a relatively high temperature to the cold air discharging air course by forcibly convecting the cold air from the cold air forcibly circulating blower by opening the first motor-driven damper for the cold storage room in a state where a compressor is stopped before the defrosting heater is energized.
