Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention of this application relates to a heat storage floor heating unit of a radiation control type. More specifically, the present invention relates to a new heat dissipation control type heat storage floor heating system which can improve the workability by integrally forming a heating element, a heat storage material, and a bag body in a joist. It is about a unit.

[0002]

2. Description of the Related Art Conventionally, as a heating device for a house or the like, a floor heating structure in which a heating element driven by electricity or gas as a driving source is provided below a floor surface is known. There is also known an economical heat storage floor heating structure that can store heat from a heating element (or a heater) in a heat storage material and gradually release the heat storage to shorten the operation time of the heating element. . In particular, in the case of an electric drive heating element, there is an advantage that the heat storage material can be heated by inexpensive midnight power of the electric charge, and the heat storage can be used in the daytime.

In this heat storage floor heating structure, for example, as shown in a sectional view of FIG.
An air layer (5) is provided between a heat insulating material (1) and a floor material (3) provided therebetween with a joist (4) interposed therebetween, and a heating element (6) and heat storage in the air layer (5). Material (7) is provided. The heat of the heating element (6) is stored in the heat storage material (7), and the heat released from the heat storage material (7) heats the floor material (3) as radiant heat via the air layer (5). Has become.

[0004] However, in the case of the conventional heat storage floor heating structure as illustrated in FIG. 14, since the heat release from the heat storage material (7) cannot be controlled, a constant amount of heat is continuously supplied even when heating is not required. And release it, which increases the running cost. For this reason, it is necessary to always operate the heating element (6) at a constant interval in preparation for the need.
There were problems in terms of economy and energy saving measures.

For this reason, for example, an air bag or the like is provided below the heating element (6), and the heating element (6) and the heat storage material (7) are adjusted by adjusting the amount of air supplied into the air bag. A structure has been proposed in which the heat release amount is controlled by raising and lowering the thickness of the air layer (5), thereby changing the thickness of the air layer (5) (JP-A-4-194518). However, although the thermal conductivity of the air layer changes depending on the thickness of the air layer, the amount of the change is not so large, so that in the case of the conventional structure, the effect is not sufficiently satisfactory. .

Therefore, the inventors of the present invention have proposed a method for controlling the heat resistance and heat radiation (heat conductivity) of a closed air layer in order to make it possible to freely control the amount of heat radiation from a heat storage material in a heat storage floor heating system. Based on our knowledge, we have already developed a heat-dissipation-type heat storage floor heating structure that realizes a structure in which the heat radiation is suppressed when a low heat radiation material is placed in the closed air layer.

In this heat storage floor heating structure, for example, FIG.
In the air layer (5) formed between the heat storage material (7) and the floor material (3), a material having a high heat emissivity (for example, various resins) , A plastic sheet or film) and a bag body (11) which can be expanded and contracted, and a plane body (14) having a low thermal emissivity such as an aluminum foil or a copper foil disposed on the upper surface of the bag body (11). In addition, the bag body (11) has
For example, a fan (13) connected to the duct (12) is arranged so that air can be sent into the bag (11) and exhausted.

A description will be given of a heat dissipation promotion state and a heat dissipation suppression state related to the heat dissipation control performed in the heat storage floor heating structure having such a configuration. (Heat dissipation promoting state) When the fan (13) is operated, air is blown into the space (10) in the bag (11) through the air duct (12), and the pressure in the bag (11) increases, and the bag ( 11) swells and comes into close contact with the back surface of the flooring (3) above the bag (11). In this state, the bag (11)
Since the air layer formed inside is formed of a material having a high emissivity on both the upper surface and the lower surface of the air layer, the thermal resistance of the air layer (compared to the state of suppressing heat radiation) is reduced. Therefore, the heat radiation from the heat storage material (7) becomes larger (as compared with the case of the heat radiation suppression state). (Heat radiation suppression state) When the fan (13) is stopped, the bag (11) collapses due to its own weight. In this state, the air layer formed between the back surface of the flooring (3) and the face body (14) is formed of a face body (14) made of a material having a low emissivity on the lower surface of the air layer. The thermal resistance of the air layer increases. Therefore, the heat radiation from the heat storage material is smaller (than in the heat radiation promotion state).

By switching the state as described above, heat radiation control can be performed. In addition, the low heat emissivity facet (1
4) is arranged on the upper outer surface of the bag body (11) in the example shown in FIG. 15, but may be arranged on the back surface of the floor material (3). Becomes possible. When the face body (14) is disposed on each of the upper outer surface of the bag body (11) and the back face of the flooring material (3), the air layer is directly formed on the upper and lower faces of the face body (14). Becomes larger, and the effect of suppressing heat radiation becomes greater.

[0010] Furthermore, the face body (14) is provided with a bag body (1).
1) may be disposed on one or both of the upper inner surface and the lower inner surface. In this case, the bag (1)
The relationship between promotion and suppression of heat radiation is opposite to that in the case of the arrangement on the outer surface of 1). That is, the heat from the heat storage material (7) is promoted by the presence of a material having a high thermal emissivity such as a resin of the bag body (11) constituting the lower side of the air layer.
When air is blown into 1) and expanded, the upper side of the air layer is constituted by the low heat emissivity facet (14), so that the thermal resistance is large and the heat radiation is suppressed.

On the other hand, as the bag (11), FIG.
(A) As illustrated in (b), the inside of which is divided into two upper and lower spaces (10A) (10B) by a flexible partition (9) made of a material having a high thermal emissivity. These two spaces (10A) (10
B) is provided with fans (13A) and (13B) for blowing air through ducts (12A) and (12B).

In this case, when heat radiation from the heat storage material (7) is promoted, as shown in FIG.
By turning on the fan (13A) and turning off the fan (13B) and sending air into the space (10A) through the duct (12A), the upper outer surface of the bag body (11) is brought into close contact with the floor material (3), The lower outer surface of the body (11) is brought into close contact with the heat storage material (7). At this time, the middle partition (9) moves downward, and the face body (1) attached to the lower inner surface of the bag body (11).
4) is brought into close contact. In this state, the space (10
A) serves as an air layer for transmitting radiant heat, but since this space (10A) is formed by the bag body (11) and the partition (9) having a high thermal emissivity, the thermal resistance of the air layer is small. Heat dissipation is promoted.

Next, in order to suppress heat radiation, FIG.
As shown in (b), the fan (13A) is turned off and the fan (13B) is turned on to send air into the space (10B). The air in the space (10A) is exhausted through the duct (12A), and the partition (9) moves upward and comes into close contact with the upper side of the bag (11). In this state,
The space (10B), which is an air layer in which the face body (14) is exposed to the space (10B) and transmits radiant heat, is formed by the partition (9) having a high heat emissivity and the face body (14) having a low heat emissivity. Therefore, the thermal resistance of the air layer increases, and heat radiation is suppressed.

As described above, in the heat storage floor heating structure provided with the heat release control means (81), the operation of the fans (13A) and (13B) is operated by the switches installed in the room, whereby the heat storage material (7) is operated. From the heat can be controlled. In this case, only one fan is used. Instead, a four-way valve is used, and the ventilation from the fan is switched by switching the four-way valve to the duct (12A).
(12B), and the placement position of the face (14) is also attached to the lower side of the partition (9).
There are various aspects.

Further, in order to reduce the time for discharging the air in the bag body (11) and to reduce the remaining air, a projection or a spacer member is provided inside the bag body (11). There is also an aspect to keep. As described above, the inventors of the present invention have already realized a heat storage floor heating structure having an excellent effect that heat radiation can be freely controlled.

[0016]

However, the heat storage floor heating structure of the radiation control type as described above has a point to be improved with respect to the actual construction. This is because in this heat storage floor heating structure, a plywood (2) is installed on a large scale (not shown) and a heat insulating material (7) provided therebetween, and a predetermined plywood (2) is placed on the plywood (2). Are assembled at a position (usually a pitch of 303 mm), and the heating element (6), the heat storage material (7), and the heat radiation control are provided between the assembled joists (4) on a large scale and on the heat insulating material (7). Bags (11) are sequentially installed, and finally, a floor material (3) is attached. For this reason, there are many construction procedures and it takes a lot of time for construction at present.

Further, a plywood (2) for holding the heating element (6), the heat storage material (7), and also the bag body (11) is provided.
Since the joists (4) are arranged on the plywood (2), the arrangement of the plywoods (2) is smaller than that of the ordinary floor construction in which the joists (4) are arranged directly above the large scale. The required special construction is one of the factors, such as cost increase and extension of construction period.

[0018] Therefore, it is desired to realize easier and shorter-time construction of the heat storage floor heating with the heat radiation control type. The invention of this application has been made in view of the circumstances described above, and solves the problems of the prior art, and a heating element, a heat storage material,
It is an object of the present invention to provide a new heat radiation control type thermal storage floor heating unit which can be constructed integrally with a bag body and can be constructed between joists, thereby realizing an improvement in workability.
