PROBLEM TO BE SOLVED: To provide an open showcase capable of accurately cooling an exhibition room when controlling a blowout cool air temperature to a set temperature.SOLUTION: An open showcase 1 for cooling an exhibition room to display commodities by blowing out cool air heat-exchanged with an evaporator 9 to the exhibition room includes: a blowout temperature sensor for detecting a blowout cool air temperature to the exhibition room; an exhibition room temperature sensor for detecting a temperature in the exhibition room; and a main controller 12 and a terminal side controller 13 for controlling a blowout cool air temperature so as to bring it to a prescribed set temperature on the basis of the output of the blowout temperature sensor. A cool state in the exhibition room is determined based on the output of the exhibition room temperature sensor, and the set temperature of the blowout cool air temperature is adjusted based on the determination result. |
