Abstract

PURPOSE:To uniform the flow of heat medium, permit to accumulate heat in heat accumulating members substantially uniformly and improve heat accumulating efficiency by a method wherein a floor body, covering a space under the floor filled with the heat accumulating members, is supported by bundle members bored with through holes directed to the flow direction of the heat medium. CONSTITUTION:Ventilating ports 42, 43, 44 are closed by switching valves 40, 41, 45 simultaneously with the driving of a fan F and whereby warm-air, heated by a solar heat collector C and passing through a duct 32, flows into the heat accumulating members 2 from an opening 25 to accumulate heat uniformly by passing through the through holes 5 of the bundle members 4 and the heat may be accumulated in the heat accumulating members substantially uniformly. The air, whose heat is exchanged, recirculates to the entrance 35 of the solar heat collector C through the duct 34. At night, the switching valves 40, 41, 45 are switched to open the ventilating ports 42, 44 and whereby circulating flow of air, passing through the underfloor of a room R, is generated and the room R may be heated by utilizing the accumulated heat of the heat accumulating members 2.

The underfloor space 9 is located between the underfloor surface 7 and the surrounding cloth foundation 6.
The floor subfloor surface 7 is a space surrounded by a concrete base 1-, and a IIi thermal material 12 is attached to the surface thereof.

In addition, in the floor F space 9, there is a blind bundle member 1 in contact with the cloth foundation 6.6.
4- are placed opposite to each other in the horizontal direction, and the W1 heat material 22 is placed on the cloth base 6 on the facing surface of the bundle member 14.
．． Attach it parallel to 6. The front surface of the heat insulating material 22 is long and has the same height as the bundle member 4.14, and is exposed to the sun! ;!
IJi-plane rectangular ventilation boxes 23 and 24 communicating with the exit 31 of the container C and the vent 33 are successively arranged. Also ventilation box 23.
24, open the ventilation section 25.25 on the facing side! t,
A heating medium, for example air, can flow from the ventilation box 23 towards the ventilation box 24 .

In addition, in the underfloor space 9, each of the above-mentioned gap/bundle members I4.14
A plurality of bundle members 4- having through-holes 5 are arranged between them.
7II, erected on the bottom surface of the underfloor space 9, that is, on the heat insulating material 12, with an appropriate gap between the straight lines. Moreover, a rack 15 is passed over the bundle member 4.14 via a spacer 13 for height adjustment, and the bundle member 4 is placed between the ventilation boxes 23 and 24.
A heat storage material 2 such as crushed stone is filled including the surrounding area.

The bundle member 4 is a fully bent columnar body made of a material such as ceramic and having a large rigidity and a rectangular cross section, and on its side facing the ventilation section 25, there are a plurality of columns in the direction in which the heat medium flows. The through holes 5.5 are formed in multiple stages, upper and lower.

Attach the floor panel 16 to the above-mentioned main drawer 15, and place the floor panel 16 in the above-mentioned under-floor space 1iJ]
9, the floor panel 16 forms a floor body 10 which is a body 8 covering the underfloor space 9. The floor panel 1G is a heavy concrete panel, and a backing plate 20.20 is attached to the bottom of the base 17''.

In addition, the ventilation boxes 23 and 24 have through holes 26 and 27 on their backs, respectively.
