PURPOSE:To maintain cooling performance by altering the capacities of a fan motor for cooling a condenser and a fan motor for expediting evaporation in response to the refrigerant pressure of a condenser outlet. CONSTITUTION:An evaporator 7, an indoor fan motor 8 for cooling the containing chamber 2 of a body at a predetermined temperature are provided in the chamber 2, and a compressor 3, a condenser 4, a fan motor 5 for cooling the condenser, evaporation expediting unit 6 for evaporating drain in the chamber, a fan motor 9 for expending evaporation, and pressure detecting means 10 for detecting the refrigerant pressure of the outlet of the condenser are provided in a machine room. The cooler for a vending machine comprises an arithmetic processor for storing preset pressure to compare the pressure detected by the means 10, and control means for controlling the motors 5, 9 according to a signal from the processor. |
