PROBLEM TO BE SOLVED: To eliminate water drain operation by an operator by 100% evaporating and disposing drain water such as condensation water or defrosting water (hereafter referred to drain water) generated from a show case with a freezing and refrigerating device built in used in small and medium size shops or the like with an apparatus additionally installed in the show case and to save total energy of the shop with this device installed by using drain water for cooling the radiator of the freezing and refrigerating device to save extra energy consumption for evaporation and improving cooling efficiency of the freezing and refrigerating device. SOLUTION: Drain water generated from a cooler of the freezing and refrigerating device of the show case is atomized with an ultrasonic oscillator and atomized water is blown out right before the radiator of the freezing and refrigerating device to cool the radiator and evaporate atomized water with heat thereof for completely evaporated the same. Since just blowing out atomized water causes re-condensation, leak and contamination by unwanted bacteria, a storage tank and an atomization tank are separated and conditions to avoid reproduction of unwanted bacterial as much as possible and to perform efficient atomization are maintained, and atomized water is supplied when the radiator is under a high temperature condition.
