室を所定温度に冷却するものである。In the above configuration, when the refrigerated open showcase starts operating, that is, when the temperature of the storage room is high, the air sucked in from the air intake port contains a large amount of moisture, so first only the refrigeration unit of the dehumidifying cooler is operated. Then, the dehumidifying cooler dehumidifies the air and lowers the temperature of the storage room to a certain extent.Then, the refrigeration unit of the main cooler is operated to further cool the air cooled by the dehumidifying cooler and then supply it to the storage room. It cools the room to a predetermined temperature.
尚除湿冷却器の表面に結露した水分はドレン排出孔（図
示せず）を介して外部へ排出される。The moisture condensed on the surface of the dehumidifying cooler is discharged to the outside through a drain hole (not shown).
