DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air circulation type floor radiant air conditioning system, and more particularly, to a heated or cooled conditioned air blown into a conditioned air passage under the floor to provide a floor surface. And a floor radiation air conditioning system that heats or cools the room and heats or cools the indoor environment by heat radiation or cold radiation of the floor surface.

2. Description of the Related Art As a building air conditioner, a convection type air conditioner and a radiant type air conditioner are known. A convection type air conditioner forcibly circulates a relatively low or high temperature controlled air into a room and cools or heats an indoor environment by indoor convection of the temperature adjusted air, while a radiant type air conditioner uses a floor facing the room. The surface temperature of a surface, a wall surface or a ceiling surface is cooled or heated, and the indoor environment is cooled or heated by heat radiation or cold radiation. From the viewpoint of improving the indoor temperature distribution, preventing discomfort due to forced convection of indoor air, and further emphasizing occupants' comfort or sensible temperature, radiant cooling and heating devices have received particular attention in recent years. The number of cases of buildings employing a radiant or radiant air conditioner as equipment is gradually increasing.

As this type of cooling / heating device, for example, a floor heating device of a hot water circulation system and a hot air circulation system is known. The hot-water floor heating device forcibly circulates hot water through the buried floor piping, whereas the hot-air floor heating device sends warm air to an underfloor pit or a tunnel to heat the floor surface. This type of warm air type floor heating device is generally known as an ondol that circulates warm air under the floor of a low-rise house or the like. The hot-air floor heating system exerts an excellent heating effect due to the unique action of hot air as a heat medium, but the hot-air flow path, such as a pit under the floor or a tunnel, must be arranged under the floor, and this must be implemented. This requires special consideration for the structure of the building. For example, when a hot-air floor heating device is installed in a middle-to-high-rise building, the floor structure of each floor is designed to have a double-floor structure, and a hot-air flow path that circulates hot air is provided below the floor of each floor. The double floor structure of such a hot-air floor heating device has a number of columns or supporting legs erected at predetermined intervals on a floor slab such as a concrete slab, and supports a floor component on the columns or supporting legs. The hot air flow path is formed between the floor component and the floor slab. This type of double floor structure is disclosed in, for example, Japanese Patent Application Laid-Open No. H10-169164.
And Japanese Patent Application Laid-Open No. 8-296872.

[0008] According to the above configuration of the present invention, various performances of the floor surface components such as radiation performance, control response performance, heat storage performance, heat insulation performance, and dew-proofing performance can be arbitrarily selected by arbitrarily selecting a property adjusting material. Settings can be changed. For example, the floor surface components to be installed in the air-conditioning area that requires quick start-up of the air-conditioning effect or quick control responsiveness are filled with physical property adjusting materials with relatively high heat transfer performance, and the stability of the air-conditioning effect is emphasized. The floor component to be installed in the air conditioning area to be filled is filled with a physical property adjusting material having relatively high heat storage performance, and the floor component to be installed in the air conditioning area where importance is placed on heat insulation or dew-proofing Filling a relatively high heat-insulating property adjusting material, and further filling a relatively high-strength property adjusting material into a floor surface component of the air-conditioning area requiring rigidity or strength of the flooring material. Various physical properties of the floor component can be arbitrarily set by filling the property adjusting material in the groove according to the characteristics. Therefore, according to the floor radiation type air conditioning system including such a floor component, the floor component can be laid in each air conditioning area as a heat radiation panel whose heat capacity or heat characteristics can be arbitrarily set, The floor radiation type air-conditioning system can arbitrarily and easily realize a floor heating effect and / or a floor cooling effect corresponding to a request or an air-conditioning condition for each air-conditioning area by adopting such a floor component.

For example, in the first embodiment, the physical property adjusting material 27 is filled in both the upper surface opening groove 24 and the lower surface opening groove 25 of the floor component 20 or the lower surface opening groove 2
5 may be filled, or an airtight material, a watertight material, a moistureproof material or a waterproof material may be applied or covered on the lower surface or the upper surface of the core material 22.

Further, as the cross-sectional form of the core material 22, various forms such as a smoothly curved waveform form, a waveform form composed of repetitive and continuous semicircular sections, and a waveform form having irregularly spaced openings are employed. Alternatively, as the arrangement pattern of the opening grooves 24 and 25, a pattern such as a lattice-shaped continuous groove intersecting vertically and horizontally or a continuous groove oblique to the core material 22 may be adopted.

Further, the material of the adjusting member 27 may be changed for each air-conditioning control zone in the same room. For example, the adjusting member 27 of the floor component 20 located in the perimeter zone has a relatively high heat storage performance. And / or a material having high heat insulation performance is selected, and the floor component 20 located in the interior zone is selected.
A material having a high thermal conductivity can be selected as the adjusting member 27 of.
