▎ 摘　　要

NOVELTY - The board has a heat-conducting insulating component (2) mounted on an aluminum alloy plate (1). The heat conducting insulating components are composed of a graphene heat conducting plate (201) and a polystyrene resin heat insulating plate (202). The heat graphene plate is arranged below the polystyren resin heat insulation plate. The upper surface of the poly styrene resin thermal insulation plate is coated with a heat conducting coating on the upper surface. The insulating board is provided with a thermoplastic insulating layer and a heat conductive layer. The heat can be conducted upwards from the aluminium alloy plate to the heat conducting and heat-preserving component. USE - Dry ground heating insulating plate for use in a floor heating system i.e. dry-type floor heating, of a building. ADVANTAGE - The heat-conducting and heat-preserving component is composed of graphene heat-condensing plate and polystyrene resin heat- preserving plate, so that the heat of the aluminum alloy plate can be conducted upward through the graphene heat conducting plate, and conducted to the surface of the heat conducting coating, thus improving heat conducting performance and heat conducting efficiency. The paving heat preservation plate is set on the bottom of the aluminium alloy plate, thus making the paving insulating plate to be convenient for the construction staff to assemble and disassemble and maintain in later period. The board allows a heating mechanism to be connected with a heating pipeline through the heating pipeline to form a closed water flow circulation loop through the circulation of the hot water, to supply heat to the dry floor heating insulation plate connected with the underfloor heating system. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: an underfloor heating system; and a method for controlling the underfloor heating system. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of dry ground heating insulation board. 1Aluminium alloy plate 2Heat-conducting and heat-preserving component 101Groove 201Graphene heat conducting plate 202Polystyrene resin insulation board
