Abstract

PURPOSE:To increase the temp. in a closed space by the use of a small amount of energy by a method wherein heat transfer plates are piled up on panel members with a number of hole parts on their upper surfaces to constitute a hollow floor and air is heated and circulated in the closed space of the inside of the panel members. CONSTITUTION:Panel members 1 are formed by synthetic resin material, such as polypropylene or alloy material and a number of hole parts 1b are formed and the lower space of the upper wall part 1a is constituted to be supported by support devices 1c consisting of a proper number of column-shaped members and ribs 1d. On the upper parts of the members 1 heat transfer plates 4 composed of material with satisfactory heat conductivity such as aluminum are piled up to constitute a hollow floor 5 with a closed space between the bottom plate 3 and the plate 4 and then on the plate 4 heat insulating materials 6 such as carpets with satisfactory heat retaining property are placed. By the operation of a heating means 7 and an air blasting means 8, the heated air is circulated through the inside space of the floor 5 and its heat is rapidly transferred to heat transfer plates with satisfactory heat conductivity through the part 1b and the interior of a room can be heated efficiently from the floor side.
