PROBLEM TO BE SOLVED: To restrict flowing noise of cooling medium in a vaporizer for a refrigeration chamber when switched into first refrigeration chamber cooling mode after defrosting. SOLUTION: A freezing chamber fan 12 is not forcedly operated, in spite that conventionally it has been forcedly operated for recirculation of cooling medium at low temperature held in the vaporizer 7 for a freezing chamber only when switched into first refrigeration chamber cooling mode after defrosting by a defrosting heater in the vaporizer 7 for the freezing chamber. Flowing noise of cooling medium in the vaporizer 5 for the refrigeration chamber when switched into the first refrigeration chamber cooling mode after defrosting can thus be restricted.
