  Heat from the hose member 20 that circulates the liquid supplied from the heat source unit 2 with the circulation pump 3 is transmitted to the lower metal plate 13 of the heat transfer panel 10. Heat from the lower metal plate 13 is collected by the metal member 14 on the upper metal plate 12 of the heat transfer panel 10. Heat from the lower metal plate 13 and heat from the metal member 14 are supplied from the surface of the flooring material via the upper metal plate 12. With such a configuration, the heat from the hose material 20 can be efficiently transmitted to the floor material.

  As shown in FIG. 3A, the hose material 20 is formed in a general single-layer pipe shape that has flexibility and elasticity, is excellent in heat resistance, and does not corrode. As shown in FIG. 3B, the hose material 20 may have a configuration in which reinforcing members 23 such as metal wires are embedded at predetermined intervals in the inside or the inner diameter portion. The liquid flowing in the hose material 20 is water, an aqueous solution, an oil agent, or the like, and an aqueous solution having a specific heat exceeding 1 may be used.

  The outer peripheral surface of the hose material 20 is preferably formed in a flat shape in order to ensure a contact area with the lower metal plate 13 of the heat transfer panel 10. The hose material 20 is made of various elastically deformable materials as long as the material has an elastic force that can maintain contact with the lower metal plate 13 of the heat transfer panel 10 in a state of being bent flat. be able to. The hose material 20 has durability capable of withstanding a temperature of −30 ° C. to 150 ° C., and is formed of, for example, a rubber material such as silicon rubber or a resin material such as vinyl chloride.

  In the illustrated example, the hose material 20 is disposed between a predetermined distance D (for example, 45 mm) set between the upper surface of the base member 40 and the lower surface of the heat transfer panel 10. The hose material 20 has a cross section composed of an arc portion 21 and a flat portion 22 in a state where the hose material 20 is bent in the radial direction in the space portion S1 formed between the upper surface of the base member 40 and the lower surface of the heat transfer panel 10. It has an oval shape. A flat portion 22 formed by bending the hose material 20 in the radial direction is in surface contact with the lower metal plate 13 serving as the lower surface of the heat transfer panel 10.

  The single-layer hose member 20 in the present embodiment is an annular shape having a diameter of about 70 mm, but in the space S1 having a gap D between the upper surface of the base member 40 and the lower surface of the heat transfer panel 10. In FIG. 1, the flat shape is maintained in a state of being bent into a horizontally long flat shape having a short axis diameter of about 45 mm.

  Thereby, the contact area of the outer peripheral surface used as the contact surface of the heat transfer in the single layer hose material 20 can be increased. Cold space or warm air from the hose material 20 can be stored in the space S1.

  As shown in FIG. 2, the hose material 20 is a single long single-layer pipe that is laid in a meandering manner while being alternately curved in a U shape on both sides of the upper surface of the base member 40. It is routed in a straight line along a spacer 30 that defines a predetermined distance D between the base member 40 and the base member 40, and is inserted in a routing groove 31 formed in the spacer 30 and drawn in a curved shape.
