BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of a cooling and heating system for a building according to the present invention.

FIG. 1 is a sectional view showing a main part of a building cooling and heating system according to the present invention. The construction method other than the building cooling and heating equipment shown here is a general wooden construction method, but is applicable to all construction methods such as a steel frame structure and a reinforced concrete structure, such as a two-by-four method and a panel method.

In the building heating and cooling equipment 1 according to the present invention, first, a cobblestone industry, a cloth foundation, a foundation, etc.
An underfloor structure at a predetermined interval from the floor surface is constructed. For example, on such a foundation, crushed stone 3 is laid on the ground 2, and a moisture-proof sheet 4 is laid thereon. Then, a foundation slab 6 is cast thereon, and a foundation composed of the foundation slab 6 and the foundation beam 5 is constructed.

A base 11 is mounted on the upper surface of the foundation beam 5 and is fixed to the foundation beam 5 with anchor bolts 20 shown in FIG. 12 between the base 11 on each foundation beam 5
Has been passed over. The puller 12 is further placed on a floor bundle 10 erected on the foundation slab 6. Further, floor beams 13 are stretched between the bases 11, between the base 11 and the large pulley 12, or between the large pulleys 12 in a direction perpendicular to them. A wall 17 is formed on the base 11 or the pulley 12, and a column 18 is erected. In addition, floor beam 13
A floor board 14 is stuck on the top, and a tatami mat 16
Etc. are laid.

In the above general construction method,
The floor heating system of the present invention can complete most steps in the foundation stage. First, an outside air inlet 19 is provided in the foundation beam 5 in the step of placing the foundation. After the placement of the foundation is completed, the heat insulating material 7 is coated on the entire inner surface of the box shape formed by the foundation beam 5 and the foundation slab 6. In this case, a rigid urethane foam plate is suitable as the heat insulating material 7, but it may be sprayed on site if a uniform thickness can be ensured.

Next, a water pipe 8 is laid on the heat insulating material 7 on the base slab 6. The water pipe 8 is preferably made of a non-metallic pipe such as a highly flexible resin or rubber such as polyethylene or polybutene, or a composite thereof, but it is particularly important to select a material that is unlikely to change over time. It is. The water supply pipe 8 made of these materials can be easily provided without skill.

At the time of piping, as shown in FIGS. 2 and 3, the water supply pipe 8 is fixed to the heat insulating material 7 by a simple method such as a string, a thin wire, or a clip. A steel wire 19 is laid, and concrete 9
Is installed. It is desirable that the floor bundle 10 be directly raised from the foundation slab 6. However, when the floor bundle 10 is erected on the concrete under the floor 9, the underfloor concrete 9 is sufficient to withstand the load of the floor bundle 10 or the like. It is necessary to secure a proper thickness.

As shown in FIG. 4, both ends of the water pipe 8 are connected to a hot water supply device so that hot water circulates inside the water pipe 8. In addition, the piping of the water supply pipe 8 is not limited to one system as shown in the figure, and for example, a plurality of systems may be provided for each room. In that case, the water supply control for each system may be performed by a valve provided for each system. Further, it is desirable that the water heater be provided with a temperature control device, a timer, and the like.

The outside air inlet 19 provided in the foundation beam 5 has
It is desirable to provide a dust-proof net or the like for preventing ingress of dust and the like from the outside, and desirably a one-way valve so as to only introduce outside air into the underfloor space.

As described above, the piping work for the water pipe 8 has been completed at the stage of placing the foundation, and the pipe for the water pipe 8 has not been exposed. It can proceed smoothly without worrying about the piping at all.

In the floor assembling process, the floor plate 14 is provided at a position as far as possible from the outside air inlet 19 provided in the foundation beam 5 so that the ventilation holes 15 between the indoor space and the underfloor space are provided.
Is desirably provided.

When using the cooling and heating equipment 1 for a building constructed as described above, when the hot water supply device is operated, hot water is supplied to the water supply pipe 8 on the foundation slab 6 to warm the air in the underfloor space. The heated air is supplied to the vent 1 provided in the floorboard 14.
From 5 flows into the room. At the same time, fresh air is drawn in from the outside air inlet 19, is heated in the underfloor space, and flows into the indoor space. In addition, such a flow of air,
Needless to say, it may be forcibly performed by using a supply / exhaust fan or the like installed in the ventilation port 15 or the outside air introduction port 19.

In the present invention, the air in the underfloor space warmed by the hot water in the water pipe 8 rises from the ventilation port 15 communicating the indoor space and the underfloor space to warm the indoor space, and furthermore, the underfloor concrete 9 itself is heated. The floor surface can be heated by radiant heat generated by far-infrared rays, and can be cooled and heated very efficiently.

However, the temperature may be adjusted by raising or lowering the temperature of the hot water itself. However, since the pipe of the water supply pipe 8 is buried in the concrete 9, the temperature change of the air is slower than the temperature change of the hot water. Rapid temperature adjustment may not be possible. In that case, the opening area of the vent 15 provided in the floor plate 14 may be adjusted. In addition, by partitioning the underfloor space according to the indoor space, efficient heat exchange can be performed.

Although the case of heating has been described above, also in the case of cooling, an air conditioner is installed in an underfloor space or the like, and cool air is supplied to an air supply / exhaust fan or the like installed in the vent 15 or the outside air inlet 19. By forcibly circulating the water, the indoor space can be efficiently cooled in combination with the circulation of water by the water supply pipe 8.

Of course, by incorporating the warm or cold air in the underfloor space obtained by the building cooling and heating equipment of the present invention into a conventional centralized ventilation system for a building with improved airtightness, heat insulation, etc. Alternatively, the cooling can be performed more efficiently. As such a centralized ventilation system for a building, a system that circulates not only the air in the indoor space but also the air in the underfloor space and the air in the attic or in the wall is known.

FIG. 5 shows a second embodiment of the present invention. In the first embodiment, outside air is introduced into the underfloor space and heated to be sent into the indoor space. In this embodiment, air is circulated between the indoor space and the underfloor space. It is. The piping of the water pipe 8 is the same as in the first embodiment. In this embodiment, another vent 21 is provided in the floor plate 14, one is a vent 15 from the indoor space to the underfloor space, and the other is a vent 21 from the underfloor space to the indoor space. These are preferably provided with one-way valves.

FIG. 6 is intended to seal a gap which is easily formed between the base beam 5 and the base 11. The heat insulating sheet 23 is interposed between the base beam 5 and the base 11, By filling the gap with the base 11 with a spraying material or a caulking material 24, it is possible to reliably seal the space. The treatment with the heat insulating sheet 23 or the caulking material 24 may be used alone or in combination. Such processing is indispensable for efficient cooling and heating of a building.
