PURPOSE:To permit economical room heating, by a method wherein a heat insulative ceiling panel, provided with a material high in far infrared rays radiating rate on the surface of the panel, is arranged and high-temperature air is supplied to the space side of the surface of the panel to effect the room heating while activating the radiating effect of the far infrared rays of the surface of the ceramics panel. CONSTITUTION:A ceramics panel 1, arranged so as to constitute a ceiling surface and having a high far infrared radiating rate, is made by an aluminium oxide series ceramics panel having the high radiation rate of far infrared rays of wave length band of 8mum-12mum. Air heated by an air-conditioning machine 4 is supplied to a supplying duct 6 and is blown off through blow-off ports 2, provided on the side walls of a space, with the temperature of 30 deg.C-40 deg.C substantially at the vicinity of said blow-off ports 2. The air flows to the side of a suction port 3 along the lower surface of the ceramics panel 1 and heats the lower surface of the ceramics panel 1. The ceramics panel 1, heated by the air, radiates far infrared rays downward from the lower surface of the panel 1. |
