PURPOSE:To eliminate an unnecessary driving of a fan for evaporator to prohibit rising of temperature in a goods-housing room by a method wherein a vendor has a defrosting operation mode and the fan is driven only when the evaporator is in a cooling operation, if the vendor is in any other operation mode than the defrosting one. CONSTITUTION:This vendor including cooling instruments such as a compressor 7, in which fans for evaporator 5a and 5b are driven to circulate air cooled by evaporators 4a and 4b to goods columns 2a and 2b has a defrosting operation mode in which the fans for evaporator 5a and 5b are driven to remove regularly frost attaching to the evaporators 4a and 4b. In this instance, it is set that if the vendor is in any other operation mode than the defrosting one, the fans for evaporator 5a and 5b are driven only when the evaporators 4a and 4b are in the cooling operation. Thus, the fans for evaporator 5a and 5b are driven only when the evaporators 4a and 4b are in the cooling or regular defrosting operation mode, and not in any other operation mode. Therefore, there is no unnecessary driving of the fans for evaporator 5a and 5b. |
