摘要： PROBLEM TO BE SOLVED: To provide the laying structure of a cooling heating panel, wherein an air reservoir is prevented from formation at the interior of a cold and hot water flow pipe. SOLUTION: A cooling and heating panel 3 is laid in an inclining state in a given spot. A cold and hot water supply header 6 is arranged on the low position side of the inclining state, and a cold and hot water discharge header 7 is arranged on the high position side of the inclination state. Cold and hot water 10 is supplied from the cold and hot water supply header 6 to a cold and hot water flow pipe 8 in the cooling and heating panel 3. Thereafter, the cold and hot water 10 is discharged through the flow pipe 8 to the cold and hot water discharge header 7. Buoyancy toward a high position based on a difference in elevation due to laying in an inclination state is generated at air generated at or braced in the internal part of the cold and hot water flow pipe 8. Thus, air in the cold and hot water flow pipe 8 is smoothly moved toward the cold and hot water discharge header 7 in a high position together with a flow of the cold and hot water 10. Air 11 discharged in the cold and hot water discharge header 7 is trapped by an air discharge valve 9 and released in the atmosphere. This constitution prevents formation of an air reservoir, by which lowering of cooling and heating efficiency is caused, at the internal part of the cold and hot water flow pipe 8.

SOLUTION: Flexible warm water piping 1, 2 coming through the inside of a sleeve embedded in floor concrete 4 are derived on the concrete surface by obliquely penetrating through a concrete floor to be smoothly raised up on the concrete surface to connect the pipe end to warm water inlet/outlet 7a, 7b of a floor heating panel 7 so as to cover a part appearing on the concrete floor upper surface of the warm water piping with a plastic cover panel 8a having the same thickness as the floor heating panel. This panel is formed into plural kinds such as a Y shape of passing warm water piping, a 1/4 circular arc shape or a shape of arranging a straight line-shaped groove 81 on the under surface.
