Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temperature control structure of a building having a space below the floor, such as a general house, and particularly to a temperature control medium circulation type building.

[0002]

2. Description of the Related Art Even with the development of heating technology, spot heating of a specific room or location using simple heating means such as an oil stove or an electric kotatsu is still widely performed in ordinary houses and nursing homes. ing. Spot heating causes dew condensation in non-heating areas such as closets if the heat insulation of the building is insufficient.When moving from a heating room to a non-heating room, the temperature difference between the two rooms is large even if it is slight There is a problem that a person feels a lot of cold due to a difference in the perceived temperature. Even with the cooling technology, there is no condensation in summer, but the problem of the perceived temperature difference based on spot cooling is the same as in the case of heating.

[0003] Central temperature control systems and floor cooling and heating systems
Although the above-mentioned problems of spot cooling and heating can be overcome, those structures that are currently in widespread use generally have extremely high construction costs, and have the drawback that operating costs are high throughout the year.

Japanese Patent Application Laid-Open No. 2-272235 discloses a special temperature control structure in order to solve the above-described problem of spot heating using an oil stove or the like. In the temperature control structure, the underfloor space above the dirt containing the hot water pipe and the attic space communicate with each other to allow natural circulation of air, and the temperature of the circulating air is heated by heating the air in the underfloor space with the hot water pipe. Raise it to heat the entire building evenly.

[0005] By the way, from the research of the present inventors, in the above-mentioned known technique, regardless of the degree of heating by a hot water pipe,
It has been found that forcibly disturbing the air on the dirt surface can unexpectedly efficiently reflect the temperature of the dirt itself in heating the entire building.

[0006]

DISCLOSURE OF THE INVENTION The present invention has been completed based on the above-mentioned new findings.
An object of the present invention is to provide a temperature control structure of a building capable of efficiently controlling the temperature of the entire building or the entire desired temperature control portion in the building by solving the problem based on spot-like cooling and heating.

[0007]

The present invention has the following features. (1) The underfloor space and the attic space on the base of the building communicate with each other through a temperature control medium circulation passage arranged so as to control the temperature at a desired temperature control point in the building, and the base A temperature control structure for a building, comprising a disturbance means for disturbing at least a part of the temperature control medium layer so as to improve the heat transferability of the temperature control medium layer existing immediately above or near the surface of the building. (2) The base portion includes a peripheral portion having a heat insulating material layer and a ground temperature utilization portion, and the disturbance means disturbs at least a part of the temperature control medium existing on the peripheral portion and / or the surface of the ground temperature utilization portion. The temperature control structure of a building according to the above (1), which can be used. (3) The temperature control structure for a building according to the above (1) or (2), wherein the disturbance means can blow gas toward the surface of the base.

[0008]

By disturbing the temperature control medium (usually air) on the surface of the base by a disturbance means, the temperature of the base itself can be efficiently transmitted to the temperature control medium in the underfloor space.
Further, the temperature control medium can circulate between the underfloor space and the attic space via the temperature control medium circulation passage to efficiently control the temperature of the entire building or the entire desired temperature control location in the building. As a result, the conventional problem based on spot cooling and heating is solved.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The temperature control medium in the underfloor space is likely to flow due to a specific gravity difference based on a temperature difference, but forms a film just above the surface of the base portion and frequently circulates thereon. It often forms a stagnation layer that is difficult to flow. These films and stagnation layers, especially stagnation layers, are factors that hinder good heat transfer. Therefore, the disturbance means used in the present invention has a function of destroying at least the stagnation layer by disturbance and improving the heat transfer property of the temperature control medium. Note that, among the disturbance means, those capable of destroying both the stagnant layer and the boundary film by disturbance are preferable. As the disturbance means, various devices and devices can be adopted as long as the function can be performed. For example, a device that can blow a gas such as air toward the base surface, such as a fan or a blowing device, is exemplified.

In the present invention, the surface of the base portion is a surface indicated by a symbol S in FIG. 1 and the like, which will be described later, and its area (surface area) is an L-shape surrounded by an outermost line 7 in FIG. The area of the figure is equal to the site area of the building when the desired location for temperature control is the entire building. If there is unevenness on the surface of the base, it is considered as the projected area on a plane. Thus, in the present invention, the destruction effect by the disturbing means does not necessarily need to be applied to the entire surface of the base at the desired temperature control location,
It is effective to apply at least a part thereof, for example, about 20 to 60% of the entire surface.

Hereinafter, the present invention will be described in more detail with reference to the drawings. 1 is a sectional view of an embodiment of the present invention, FIG. 2 is a plan view of a base portion in FIG. 1, FIG. 3 is a partially enlarged sectional view of the base portion in FIG. 1, and FIG. 4 is a cross section of another embodiment of the present invention. FIG. 5
FIG. 6 is a sectional view of still another embodiment of the present invention, and FIG. 6 is a plan view of a base portion of still another embodiment of the present invention.

In FIG. 1 to FIG. 3, when the building H is viewed from above (see FIG. 2), its base 4 is L-shaped, and the above-mentioned 1 is provided above the rising portion 5 provided at the end of the base 4. ~
The respective parts indicated by reference numerals 3, R1, R2, etc. are formed. Since the outer wall of the rising portion 5 comes into direct contact with the outside air, the heat insulating material layer HI is provided on the outer wall. Reference numeral 41 denotes a peripheral portion of the base portion 4, and reference numeral 42 denotes a ground temperature utilization portion of the base portion 4. The ground temperature utilization part 42 is in a state where its periphery is surrounded by a peripheral part 41. In the peripheral portion 41, a heat insulating material layer HI is laid on the lowermost surface of the concrete. In the base portion 4 of the building H, a portion that is easily affected by the outside air temperature throughout the four seasons is the peripheral portion 41. Since that portion has the heat insulating material layer HI, a function of protecting the ground temperature utilization portion 42 from the outside air temperature is provided. Eggplant

In order to prevent moisture and moisture in the ground from penetrating into the heat insulating material layer HI and impairing its heat insulating effect, the front end of the heat insulating material layer HI is, as shown in FIG. 42
Dig into concrete. On the other hand, the ground temperature utilization section 42 has no heat insulating material layer HI or the like, and the lower surface of the concrete layer is in direct contact with the ground and is affected by the ground temperature. EH1, EH2, and EH3 are heater units embedded in the rising portion 5, the peripheral portion 41, and the ground temperature utilization portion 42, respectively. It should be noted that the shape of the building targeted by the present invention is not limited to the above-described L-shape.

In FIG. 2 and FIG. 6 described later, the boundary between the peripheral portion 41 and the ground temperature utilization portion 42 is indicated by a dotted line. The width W of the peripheral portion 41 is between the end of the base portion 4 and the tip of the heat insulating material layer HI, and is usually about 10 to 150 cm, especially about 30 cm.
It is about 100 cm. However, when the front end of the heat insulating material layer HI and the vicinity thereof are destroyed and the original function as the heat insulating material layer cannot be exhibited, the front end of the normal portion may be set as the front end of the heat insulating material layer HI.

Each fan as the disturbance means 6 has a peripheral portion 4
It is installed so that the temperature control medium can be sprayed on the surface of the ground 1 and / or the surface of the ground temperature utilization unit 42.

The portion above the underfloor damper W2 of the building H has a double-walled structure as shown in the figure except that all of the side walls and roof other than the window W1 and the ridge damper W3 of the room R2 have a double-walled structure. 3 is a passage 31 between the outer wall of the room R1 and the double side wall of the building H, a passage 32 between the outer wall other than the window W1 of the room R2 and the double side wall of the building H, and the room R
1 and a passage 33 between the outer walls of the room R2, and the attic space 1 and the underfloor space 2 have these three passages 31 to 31.
It communicates via 33. In the passage 33 of the temperature control medium circulation passage 3, a temperature control medium circulation forcing means 331 including a blower 332 and a pipe 333 is provided.

FIG. 3 shows a sectional structure of the peripheral portion 41. In the figure, 411 is a crushed stone layer, 412 is a waterproof layer made of a waterproof material such as polyethylene sheet and asphalt,
HI is a heat insulating material layer, 413 is a spacer formed by rolling a wire, 414 is a wire mesh stretched over the spacer 413, EH2 is a heater unit fixed on the wire mesh 414, and 415 is concrete. is there. The crushed stone for forming the crushed stone layer 411 may be of a type and a size generally used when concrete is cast. Examples of the constituent material of the heat insulating material layer HI include porous inorganic materials such as rock wool, glass wool, expanded vermiculite, and shirasu balloon, foams of organic polymers such as polyethylene, polystyrene, and polyurethane, or sawdust and paper. A non-water permeable sheet which is subjected to a waterproof treatment as necessary using the above-mentioned heat insulating material is exemplified.

The only difference between the cross-sectional structure of the ground temperature utilization part 42 and that of the peripheral part 41 is that there is no heat insulating material layer HI and that a heater unit EH3 is provided instead of the heater unit EH2.

The embodiment shown in FIG. 4 is different from the embodiment shown in FIGS. 1 to 3 in that there is no heater unit EH3 in the ground temperature utilization section 42 and a number of fans as the disturbance means 6 are provided on the base 4. It is merely installed so that the temperature control medium can be sprayed toward the surface of the peripheral portion 41.

The embodiment shown in FIG. 5 is different from the embodiment shown in FIGS. 1 to 3 in that none of the rising portion 5, the peripheral portion 41 and the ground temperature utilization portion 42 have a heater unit, and the disturbance means 6 is used. It is only that a large number of fans are installed on the peripheral portion 41 or the ground temperature utilization section 42 so that the temperature control medium can be sprayed toward the surface of the ground temperature utilization section 42.

The embodiment shown in FIG. 6 differs from the embodiment shown in FIG. 4 in that two pumps 6 are used instead of a large number of fans.
1, suction pipe 62, supply pipe 63, and annular distribution pipe 64
It is only that the disturbance means 6 consisting of The annular distribution pipe 64 is provided along the outer periphery of the ground temperature utilization unit 42, while each of the pumps 61 is connected to the underfloor space 2.
(Not shown), it is installed on the base 4 (on the ground temperature utilization part 42). The temperature control medium in the underfloor space 2 sucked into the pressure pump 61 from the suction pipe 62 is sent to the distribution pipe 64 via the supply pipe 63, and is discharged from the many exhaust holes 65 formed in the distribution pipe 64 to the periphery. It is ejected toward the surface of the part 41.

Hereinafter, the operation method of each embodiment will be described. First, the simplest embodiment of FIG. 5 having no heater unit will be described. In general, the surface directly below buildings, especially underground, has a stable temperature close to the average annual temperature throughout the four seasons. In the following, the ground surface temperature and the underground temperature thereunder are collectively referred to as ground temperature. Base 4
Has a heat insulating material layer HI on the lowermost surface of the concrete casting, and is insulated from the ground temperature. On the other hand, since the ground temperature utilization unit 42 is in communication with the ground, it maintains the ground temperature or a temperature close thereto. So now tentatively 4
Is efficiently transmitted to the temperature control medium in the underfloor space 2, the temperature of the temperature control medium is equal to the underfloor damper W2.
The temperature is substantially determined by the temperature of the ground temperature utilization unit 42 unless special measures such as forced inflow of outside air from the ground are taken.

Since the ground temperature utilization section 42 constantly maintains a temperature close to the annual average temperature, the temperature control medium in the underfloor space 2 is temperature-controlled by the ground temperature utilization section 42 in a direction approaching the annual average temperature, and is generally in late autumn. From winter to early spring through winter, the temperature is higher than the outside air temperature, while in summer when cooling is required, the temperature is lower than the outside air temperature. This temperature control medium functions in a direction of circulating through the temperature control medium circulation passage 3 throughout the building H and naturally controlling the temperature. During the temperature control by the ground temperature utilization unit 42, the ground temperature utilization unit 42, particularly its surface layer,
Reduced by heat transfer to temperature control medium in underfloor space 2 (winter)
Or, the temperature rises (in summer), but since the lower surface of the ground temperature utilization unit 42 is in contact with the ground having a large heat capacity without passing through the heat insulating material layer, heat is constantly supplied from the ground or heat is absorbed by the ground. However, the degree of the decrease or increase is unexpectedly small. As a result, the ground temperature utilization unit 42
Even without special heating or cooling from outside, the entire building H is naturally temperature-controlled as described above.

However, the heat transfer from the ground temperature utilization section 42 to the temperature control medium in the underfloor space 2 is performed as described above.
Is generally hindered to some extent by a stagnation layer or a boundary layer of the temperature control medium existing on the surface of the medium. On the other hand, in the embodiment shown in FIG.
The stagnation layer and the like can be broken by spraying the temperature control medium toward the surface of the slab, and as a result, the heat transfer from the ground temperature utilization unit 42 to the temperature control medium in the underfloor space 2 is improved.

In general, humans strongly desire a warm room temperature of about April to May in late autumn or winter, so that the above-mentioned natural temperature control alone still causes cold, and conversely, in summer, the temperature is slightly lower than the outside air temperature. Even at low temperatures, they often feel cool. In order to meet this demand in winter or the like, in the embodiment shown in FIGS.
1 and the heater unit EH3,
Are provided with a number of fans which can additionally heat them and which can spray a temperature control medium on their surface. At this time, the heat insulating material layer HI of the rising portion 5 and the heater unit EH1 function to block the influence of the cold outside air temperature into the underfloor space 2.

Each of the embodiments shown in FIG. 4 and FIG.
Although the heater unit EH3 inside is omitted,
Since heater units EH1 and EH2 are provided (not shown in FIG. 6), and each of the disturbing means 6 is installed so as to blow air toward at least the surface of the peripheral portion 41, FIG.
3 can respond to human needs in late autumn and winter as in the embodiment of FIG. It should be noted that the ground temperature utilization part 42 is surrounded by the peripheral part 41 having the heater unit EH2 and is shielded from the cold outside air temperature, so that it maintains a temperature closer to the ground temperature. Use efficiency is increased.

In the present invention, the disturbance means 6 does not need to be operated at all times, and may be provided with the ground temperature utilization section 42 or the heater unit EH with or without the heater unit EH3.
When the required degree of heating is not achieved by the spontaneous release of heat only from the peripheral portion 41 having the structure 2, the disturbance means 6 is operated to forcibly extract heat from them or a part thereof. Good.

Further, a temperature sensor may be attached to the rooms R1, R2, etc. requiring heating, and the opening and closing of the underfloor damper W2 and the ridge damper W3 may be linked to the operation of the disturbance means 6. Thus, on days when the outside air temperature is low, the dampers are closed and only the disturbance means 6 are operated to increase the degree of heating, and conversely, on days when the outside air temperature is high, these dampers are opened and the disturbance means are also operated to operate the heat. Can be released outdoors, and comfortable temperature control is possible.

If the surface area of the peripheral portion 41 occupying the surface area of the base portion 4 (the area having the width W in FIGS. 2 and 6) is excessively large, the area occupied by the ground temperature utilization section 42 is reduced, and the effective utilization of the ground temperature is achieved. Becomes substantially impossible. On the other hand, if the surface area of the peripheral portion 41 is too small, the function of the peripheral portion 41 becomes poor. Therefore, the surface area of the peripheral portion 41 occupying the surface area of the base portion 4 is 30 to 65%, particularly 40 to 60%.
On the other hand, it is preferred that the surface area of the geothermal utilization part is at least 30%, especially at least 35%, of the surface area of the base part.

The material for forming the ground temperature utilizing section 42 is not particularly limited as long as it can perform the function of utilizing the above-mentioned ground temperature.
The surface layer may be made of concrete as shown in FIGS. 1, 4 and 6, or may be entirely soil including the surface layer. In order to efficiently use the more stable soil temperature of the deep soil at least 50 cm, particularly at least 1 m from the surface of the earth, the ground temperature utilization unit 42
It is also preferable to have a large number of heat conductive members such as metal rods and metal tubes reaching such a deep layer.

When the outer wall of the building H has a double structure, the above-mentioned effect of the present invention is further enhanced, which is extremely effective. Further, it is preferable that the window also has a double glass structure. Instead of the outer wall of the building H having a double wall structure, a layer of a heat insulating material similar to the constituent material of the above-described heat insulating material layer HI may be provided inside and / or outside the outer wall.

As a modified example of the temperature control medium circulation passage 3, a part of the temperature control medium circulation passage may be a part of a room to be subjected to temperature control in a building. Such a room is provided with a ventilation hole that opens to the temperature control medium circulation passage on the ceiling, side wall, floor, or the like. In this case, the room may be contaminated by the circulating air flow as the temperature control medium. In such a case, the underfloor damper W2 and the ridge damper W3 shown in FIG. 1 and the like are useful for ventilation.

In the above, heating in winter has been described. However, in the present invention, if a cooling means such as a cold water pipe for flowing cold water is used in place of the heating means such as the heater units EH1 to EH3, the same principle as described above is used. Effective cooling can be performed in summer.

In the case of a single-family private house, the whole building is usually subjected to temperature control irrespective of the number of floors. In some cases, for example, only half of the building may be subject to temperature control. The present invention can be applied to the whole building or any part thereof. Therefore, the temperature control medium circulation passage is arranged so that at least a desired location in the building can control the temperature and communicates the attic space and the underfloor space. The arrangement position of the temperature control medium circulation passage and the number of passages
The number of passages is arbitrary as long as the object of the present invention is achieved, but the number of passages is preferably one or more, particularly preferably two or more. Further, it is preferable to provide two or more passages immediately inside the outer wall of the building. For example, when a space is provided between the inner surface of the outer wall and the outer wall of the temperature-controlled room, the space is provided, and when one surface of the temperature-controlled room is a glass window also serving as the outer wall of the building, the space is provided. Each of the temperature control chambers can be used as a temperature control medium circulation passage. When the outer wall of the building is a double wall or a double glass window, it is preferable to provide a temperature control medium circulation passage inside the double wall or the inner wall of the glass window.

[0036]

According to the present invention, it is possible to efficiently control the temperature of the entire building or a desired temperature control point in the building by solving the problems based on spot-like cooling and heating. It is suitable for temperature control.
