PROBLEM TO BE SOLVED: To provide a refrigerator capable of stably keeping the inside at a required temperature while sufficiently improving energy-saving performance.SOLUTION: A control board 31 disposed at a ceiling wall top face side of a refrigerator body 1 controls setting of energization rates of temperature compensation heaters (a rotary partitioning heater, a water supply pipe heater, a vegetable compartment heater 57) which are disposed in a heat insulating housing 10 and to which commercial power source voltage is applied, to change the energization rates to keep constant output values, according to a degree of a cold air circulation amount estimated on the basis of composite conditions including a relation of a level of an outside air temperature indicated by a temperature detection signal from an outside air temperature sensor indicating an outside ambient temperature corresponding to a level of the commercial power source voltage, and an inside temperature indicated by temperature detection signals from temperature sensors of storage compartments (a refrigerating-temperature compartment temperature sensor 33, a freezing-temperature compartment temperature sensor 34 in lower freezing-temperature compartment 5, and a vegetable compartment temperature sensor 33a in a vegetable compartment 6). |
