PURPOSE:To prevent the generation of temperature difference in a storage chamber, in a low-temperature cabinet, in which the inside of the storage chamber is cooled by the latnet heat of melting of cold accumulating agent. CONSTITUTION:Fans 12, 13, circulating cold air, cooled by the latent heat of melting of cold accumulating agent, through the inside of a storage chamber, are provided. The operation of the fans 12, 13 is controlled by a controller C to cool the storage chamber to a set temperature. The controller C reduces the rotating numbers of the fans 12, 13 in accordance with the reduction of temperature of the storage chamber. |
