PROBLEM TO BE SOLVED: To save energy by suppressing sensible heat load of a moisture permeable film humidifier in a refrigerating device for humidification by supplying warm water to the moisture permeable film humidifier. SOLUTION: A moisture permeable film humidifier provided in a freely water temperature adjustable water circulating circuit and a freely air flow rate adjustable blower for supplying air to the moisture permeable film humidifier are provided, and a temperature sensor for detecting the temperature of this air and a humidity sensor for detecting the humidity of the air are provided. The relation between the outlet air status and the air volume and that between the outlet air temperature and the sensible heat load of the moisture permeable film humidifier are calculated in advance (ST21). The sensible heat load is set (ST22), while referring to the detected value of the sensor and the relation between the outlet air temperature and the sensible heat load or the like, an equivalent outlet air temperature for causing the sensible heat load to be a set value is calculated (ST23), and an equivalent air volume is calculated (ST24). |
