Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a surface heating structure using a Ja homogeneous heat storage shrine. In particular, the present invention mainly relates to a surface heating structure that performs floor or wall heating effectively and economically while saving energy. body f
Generally speaking, surface heating of floors, walls, ceilings, etc., is well known as a method of indoor heating in buildings. This is one of the 11ρl methods that has become popular in recent years.A typical example of surface heating in a building is a one-floor heating system, which uses a luxurious heating element, such as electric floor heating, hot water floor heating, and 711A style. The standard structure of this type of floor heating system is that of the foundation structure of a building made of concrete or wood, which has a certain thickness of insulation to reduce heat loss. A heating element is placed on top of the heating element, and a heating structure is made using plywood, concrete, mortar, plaster, etc., singly or in combination, and the floor is finished with carpet, PVC long flooring, etc. It has been laid and finished with edges.

Floor +1. The characteristics of surface heating represented by the Q room are that it heats the room using radiant heat and conduction heat from the entire surface, so it is superior to the convection effect of the indoor air and the indoor temperature distribution. Compared to 11i heating methods such as electric stoves, it provides comfortable heating without the disadvantages of heating the ceiling too much and making your feet feel too warm. In addition, central heating does not require heating even in rooms that do not need it, and there is little heat loss, and it is also possible to provide general heating without burning indoor air with carbon oxide, etc., and to provide ventilation. Because of this, there is no need to open the windows.In addition, it is a safe heating system that does not cause burns or fires if the unit is touched or knocked over. This heating method is becoming popular in social welfare facilities, medical facilities, sports facilities, etc.

In general, for floor heating, etc., since there is only a heating element in a part of the music, the surface height of the entire surface is kept as uniform as possible by making it into a fixed-length panel using methods such as tii + t + A to prevent heat transfer. In addition, the surface height of the entire surface is made uniform by providing a heat storage layer of a certain thickness in the northern part of the heating element.
11 or as an effect -V↓The heat generated by the heating element is stored in this heat storage layer (from this, if you turn off the heat source such as oil or electric stove, the temperature in the room will be reduced).
(This will not happen, and even if the heat dissipation of the heating element decreases in the middle of the 11th room, or the heat source is turned off with a thermostat, etc., the room temperature will not suddenly drop in a short period of time.)

It has the effect of quickly recovering the room temperature even if the room gets cold due to the closing of the 111 in the middle of a samurai, etc., and maintains the surface temperature of the blood 11 chambers at a constant level. Storing heat in such a heat storage layer makes the indoor temperature uniform, reduces power consumption, and lowers electricity bills, resulting in energy savings.

As a way to more actively utilize the role of the heat storage layer in the 7-room device, the nighttime heat storage layer 1 stores the amount of heat generated from the heating element by using late-night electricity, which is cheaper. Recently, attempts have been made to heat the room by radiating heat from the room.

Concrete, mortar, plaster, etc., which have sensible heat type #thermal properties, are used as floor structures and heat storage layers.

However, the specific heat of concrete, mortar, plaster, and other sensible heat storage materials is as small as approximately 0.2 ca5/f, so in order to heat up the amount of heat in the human world, we must use sensible heat storage materials. It is necessary to increase the difference between heat storage and heat radiation. However, when considering surface heating equipment, it is better to keep the indoor temperature as uniform as possible, and in that sense, the smaller the temperature difference, the longer it will not be possible to make a large difference, so the amount of heat stored in the large rat is If you try to do this, you will have to use Ousu's sensible heat storage material. 1111 In order to effectively perform thermal storage floor heating using electric power, the sensible heat storage layer must have a thickness of 15 to 20 rfn or more. In addition, the floor layer becomes unnecessarily thick, and the vehicle M also becomes large. In addition, with sensible heat storage materials, when the amount of heat stored is released, the temperature of the material decreases by that amount.
% It's very difficult to keep the 1st uniform 671
There are some drawbacks that make it worse.

The present inventors have further focused on the role and effect of the heat storage layer in such P'(: equipment), and have made use of the energy saving layer by improving the various drawbacks of the conventional sensible heat storage material. As a result of intensive study to create a heating car with a uniform room temperature, we found a unique material with moisture permeability of 11 divided by 1. ] By using 'l-type heat storage ('), it is possible to easily use ifu heating, which is large enough to maintain a uniform room temperature with a small number of materials.
They discovered this and completed the present invention. That is, the present invention has a special feature that the controllable heating element is made of a heat-proof material (thus a hermetically sealed coagulable heating material and a heat-insulating material). This is a structure for each cell.

The features of the present invention are as follows: 11.・By using a heating material, compared to sensible heat storage materials, it is possible to store a large amount of heat with a small amount of heat storage material, and the thickness of the conventional heat storage layer can be made extremely thin, making it especially 1. A heat storage type floor 11υ room that uses low-cost late-night electricity.
This is valid. Also, 111 total i! h Since heat storage materials store and release heat by using the latent heat of melting and solidification of the material, as in sensible heat storage, the temperature of the material rises during 1ζ heat storage, and when heat is released, the material jt, ? As the temperature decreases, the phenomenon disappears,
Since the temperature is always constant during heat storage and heat dissipation, there is little change in temperature on the surface of the structure for the 11th wife indoors. ^1v is uniform (there is a characteristic that this is the case.Also, since the solidifying heat storage material has a clear end point of melting and solidification of the material, for example, the heat source of the heating element is stopped at the melting end point l, and the heat source of the heating element is stopped at the end point of 1Btliil). It is easy to control lAi'+ degrees by using the end point of the heating element, such as putting it in.
It also saves energy by not raising the temperature unnecessarily.Also, the specific heat of coagulable heat storage materials is higher than that of concrete, mortar, stone, f'f, etc., so it stores heat by using sensible heat. 4) The amount of material is larger than that of +'+iJ.

Next, the history of the present invention will be explained in detail.As the solidifying heat storage material used in the present invention, the heat I
To prevent the temperature from accumulating a part or equivalent of I4 and unnecessarily increase the temperature, and to reduce the temperature each time it decreases (in order to dissipate the heat hardening required for this 11ν chamber, the melting point of the coagulable heat storage material is 10 to 50 ℃
4 rectangle is suitable, preferably 20 to 4.0
It is ℃.

Below 10°C, the temperature is too low and unsuitable for heating, and above 50°C, the temperature is too high and unsuitable. The larger the heat of fusion is, the more preferable it is.If the heat of fusion is small, a large sized heat storage material is required, so it is desirable that the heat of fusion is above l 5 cge/y9i.

An example of such a heat storage material is Na 2 S04.10

In addition, in order to prevent deterioration during long-term use, containers made of synthetic resin or metal without aAl properties are filled with a certain amount of aluminum. Examples of materials for such containers include polyolefin, polyvinyl chloride, Al35. Nylon, polycarbonate, l='Rl), resin concrete,
There are iron, copper, aluminum, etc. 6 The shape of the container may be bag-shaped, plate-shaped, tubular, etc. depending on the construction method of the surface heating structure and its strength. The coagulable heat storage material of the present invention can also be used with sensible heat storage materials such as concrete, mortar, and plaster. Next, as a heating element that can be controlled, for example, as an electric heating element, a synthetic resin film or an aluminum wafer is used, or a sheet heating element using a thermal half-life body with a synthetic resin film and carbon powder added.
