The present invention relates to an improvement of a bottom structure for radiant air conditioning in which a building interior is air conditioned with radiant heat.

As a structure for air-conditioning of a building, there are some disclosed in Japanese Patent Application Laid-Open No. 59-86512, Japanese Patent Application Laid-Open No. 61-3336, etc., but all of the double bottom voids are meandered in a bottom plate or partition wall. It is fixed by deformity, and the whole room is air-conditioned.

The technique disclosed in the above-mentioned publications has a problem in that the air conditioning air passage cannot be changed after the completion of the building, and the degree of freedom of design of the publication site is small, as well as the lack of heat capacity and thermal conductivity of the bottom panel. In addition, the air-conditioning efficiency is low due to the inability to distribute the air of the air conditioning system to each air conditioning passage evenly.

The present invention, in order to solve the problems of the conventional air conditioning floor structure, there is a large degree of freedom of installation of the air conditioning air passage, even after the completion of the construction, the air conditioning air passage is free to move, high air conditioning efficiency by radiation, The heat exchange efficiency of the air emitted from the air conditioning unit and the bottom panel is also high, and there is a problem to provide a bottom structure for radiation air conditioning that can evenly introduce the air conditioning air in each passage even if there are a plurality of air passages.

In the first aspect (claim 1) of the present invention, a bottom panel having a high heat capacity and high thermal conductivity is fixed on the bottom slab by a support lever body having a predetermined height to form a bottom portion, and the top surface of the bottom slab is insulated. Air conditioner outlet openings at the gaps between the bottom and the bottom slab, and at the same time, a plurality of insulated insulation walls are arranged in the gaps to surround the heat insulating members. At the same time, a diffusion region of air conditioning air is formed in the air conditioning air passage facing the outlet.

In the second aspect (claim 2) of the present invention, the diffusion region of the air-conditioning air is formed by a duct orthogonal to the outlet.

In the third aspect (claim 3) of the present invention, a metal plate having high thermal conductivity is adhered to the back surface of the main body formed of a material having a large heat capacity such as a bottom panel, concrete, calcium silicate, and the like.

According to the fourth aspect of the present invention (claim 4), the heat insulating wall material is constituted by forming the outer and outer surfaces of the inorganic fiber mat with a laminate of metal foil and a laminate of a synthetic resin-based reinforcing sheet.

In the fifth aspect (claim 5) of the present invention, an air conditioning air return port whose flow rate can be adjusted is opened toward the room at an installation position and a symmetric position of an air outlet of the air conditioning apparatus in the floor structure. The air inlet of the device was opened to the room.

The amount of the air-conditioning air supplied to the air-conditioning air flow passage at the correct position can be made approximately equal, and the air-conditioning effect can be equalized.

According to the third aspect of the present invention, since the heat amount of the air conditioning air is efficiently conducted to the bottom panel and stored, the effect of radiation air conditioning by the bottom surface is remarkably improved.

According to the 4th aspect of this invention, the heat insulation wall for air-conditioning air path formation which is flexible, has high heat insulation, and is easy to handle light weight can be obtained.

According to the fifth aspect of the present invention, by adjusting the flow rate of the air conditioning reflux port, the heat exchange time of the air conditioner and the bottom panel sent from the air conditioner can be adjusted in a short and long time, and the effective use of thermal energy by sufficient heat exchange, or indoor air In addition, scattering prevention can be achieved, and condensation sites such as window glass at the opening position of the reflux opening can be also planned.
