PROBLEM TO BE SOLVED: To provide a show case capable of accelerating vaporization of drain water without lowering cooling performance.SOLUTION: A show case includes a refrigeration cycle 13 formed by connecting a compressor 17, a condenser 21, an expansion valve 22, and a vaporizer 14 in order by a refrigerant pipe 33. Drain water produced in the vaporizer is reserved in a drain water vaporization pan 18a, and the drain water reserved in the drain water vaporization pan is vaporized with condensation heat of a refrigerant in the refrigeration cycle. The show case includes a humidity sensor 26 which detects the humidity in a space where the show case is installed, and a controller 27 which controls the opening of the expansion valve to raise the discharge temperature of the compressor when a humidity detection value detected by the humidity sensor is higher than a preset set value. |
