CEILING RADIATION HEATING/COOLING DEVICE

PROBLEM TO BE SOLVED: To provide a ceiling radiation heating/cooling device enabling shortening of rise time and control in accordance with an indoor thermal load and capable of improving comfortability for a short time. SOLUTION: At start of heating/cooling, air-conditioning air is supplied at once to an indoor space B, so as to achieve an approximately stable state for a short time and obtain the comfortable indoor space B. Dampers 4 are opened/closed by damper opening/closing mechanisms 5 in accordance with indoor temperature load, and air-conditioning air of an air conditioner 3 is supplied from the dampers 4 to the indoor space B. Both heating/cooling by convection and radiation heating/cooling from a ceiling radiation panel 2 are used. Thus, even if the indoor thermal load is fluctuated by environments such as weather and entry/leaving of a person, control can be performed to achieve the stable state for a short time so as to enable heating/cooling corresponding to the thermal load.
