PROBLEM TO BE SOLVED: To provide a radiation panel for cooling/heating operation that is mounted as a foundation of a flooring work etc. in which an upper surface output and an upper surface heat radiation efficiency can be increased more.SOLUTION: A radiation panel for cooling/heating operation comprises a foam resin molded body 2 acting as a heat insulator, a water feeding pipe 3 embedded in grooves at a front side of the foam resin molded body, a joist-shaped member 4 for use in fixing a floor finishing material and a thermal diffusion radiation sheet 5 arranged on the surface. A linear line part of the water feeding pipe 3 is housed in a trough-like heat transfer member 6 and embedded in the grooves of the foam resin molded body 2 and a curved line part of the water feeding pipe 3 is embedded in the grooves of the foam resin molded body 2 from the upper surface of a metallic foil 7 adhered to the surface of the foam resin molded body 2 while the metallic foil is being torn. Then, an arranging pitch of the joist-shaped member 4 is set to 300 to 305 mm, an arranging pitch of the water feeding pipe 3 is set to 55 to 90 mm at both sides of the joist-shaped member 4 and locations other than both sides of the joist-shaped member 4 are set to have a pitch of about 30 to 55 mm. |
