Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an indoor heating method, and particularly to an indoor heating method using a latent heat type floor heating device installed under the floor.

[Prior art]

As an indoor heating device, a special composition with large latent heat is used as a heat storage material, and this is heated and melted with an electric heater, etc.
The heat of solidification (latent heat) released when the vaginal heat storage material solidifies afterwards.
A type of heating system that maintains heat is used.

As the heat storage material, for example, a material having a predetermined melting point (around 28°C) and a large latent heat (heat of fusion and heat of solidification), such as sodium sulfate decahydrate (N a12S O+ 10 H, O, also called Glauber's salt) things are used.

As a method for heating this heat storage material, for example, a method is adopted in which heaters made of electric heating resistors are arranged along the heat storage material and electricity is applied to the heaters to heat the heat storage material to about 40.degree.

Latent heat type floor heating systems that use such heat storage materials have a structure in which the heat storage materials and heaters are laid under the floor of a building room or gymnasium, and mortar or floorboards are laid on top of them. There is.

According to this type of floor heating system, if the heat storage material is melted in advance, heat is gradually radiated at a nearly constant temperature while the heat storage material solidifies, so that the indoor temperature can be maintained at a desired temperature over a long period of time (for example, about 10 hours). (for example, about 22°C).

For this reason, it is possible to use an economical method of melting the heat storage material using a heater at night (when the room is usually not in use) when electricity costs are low, and then turning off the electricity during the day and heating the room using solidification heat. be.

However, if the temperature of the heat storage material increases rapidly, its thermal efficiency will decrease and in some cases it will be destroyed, so it is preferable to heat it gradually. Therefore, in a latent heat type floor heating system, it is necessary to quickly and finely adjust the temperature. was difficult, and there were the following problems.

I i) Set the indoor temperature to standard temperature (e.g. 20℃)
When you want to temporarily change the setting from 23°C to 25°C, it is difficult to adjust the setting.

ii) It is difficult to cope with sudden changes in climate conditions and decreases in indoor temperature.

iii) If the device is not used for a long time and the indoor temperature has completely cooled down, it will take a considerable amount of time to start up.

〔the purpose〕

An object of the present invention is to provide an indoor heating method that can solve the problems of such conventional indoor heating methods, that can easily adjust the room temperature while maintaining economic efficiency, and that can improve startup performance when heating starts. The goal is to provide the following.

〔overview〕

The present invention provides a floor heating device that heats a heat storage material with a large amount of latent heat with a heater made of an electric heating resistor and keeps it warm mainly by utilizing the solidification heat of the heat storage material, and a ceiling heating panel that heats it mainly by heat radiation, The above object is achieved by a method of detecting when the room temperature is below a set value and driving the ceiling heating panel when heating the room with the floor heating device.

〔Example〕

The indoor heating method according to the present invention will be specifically described below with reference to the drawings.

FIG. 1 shows an example of a floor heating system suitable for carrying out the method of the present invention.

In Figure 1, a heat insulating layer 2 is installed on the upper surface (floor surface) of a floor 1 of a building made of a concrete slab, etc., and the heat insulating layer 2 is
A heater 3 and a heat storage material 4 are installed on top of the heater 3, a mortar is placed on top of these, and the heater 3 and heat storage material 4 are embedded in a layer 5 of mortar. A desired floor covering material 7 is laid on top of the mortar layer 5 to complete the floor structure. The heat insulation N2 is, for example, a board made of hard urethane foam, and serves to suppress heat loss to the floor 1.

As the heater 3, there is used a planar heating element having a structure in which a plastic mixed with conductive fine particles is used as an electrothermal resistor, and lead wires for supplying electricity are embedded in the plastic. The heat generation temperature of this type of heater is controlled to be around 50°C, for example.

As the heat storage material 4, for example, a fixed plastic case filled with a heat storage material (composition) containing sodium sulfate decahydrate or the like as a main component is used. As shown in the figure, the heat storage materials are arranged and laid on the heater 3 at predetermined intervals.

As the mortar 5, a cement-based mortar or a gypsum-based mortar, etc., can be used as appropriate in consideration of their properties, and if necessary, a plurality of types of mortar can be stacked to form a composite layer.

In addition to the floor structure shown in FIG. 1, a similar heater 3 may be installed on the upper surface of the heat storage material 4, so that the heat storage material 4 can be heated from either above or below.

FIG. 2 illustrates a ceiling heating panel used in conjunction with the implementation of the method of the present invention.

In FIG. 2, the ceiling heating panel 10 is constructed by laying a heat diffusion plate 13 made of a sheet of a good thermal conductor on the top surface of a ceiling material 12 such as a gypsum board, and placing spacers 14 and planar heating elements 15 in a desired arrangement on the top surface. It has a structure in which reinforcing plates 16 are bonded to the upper surfaces of the reinforcing plates. In this structure, the ceiling material 12 and the heat diffusion plate 13, the heat diffusion plate 13 and the spacer 14, and the spacer 14 and the reinforcing plate 16 are bonded together by adhesive. Ru.

Note that when constructing the ceiling heating panel 10, a heat insulating board 17 made of foamed plastic or the like is bonded to its upper surface (in the illustrated example, the upper surface of the reinforcing plate 16) to suppress heat radiation (loss) to the ceiling slab side. Ru.

The planar heating element 15 may have a structure similar to (or the same as) the heater 3 used in a floor heating system, for example, a plastic or rubber band mixed with powdered carbon or metal powder or the like. It has a structure in which a lead wire 18.1B for power supply is embedded in a heat generating part made of a sheet material, and the heat generating temperature is, for example, about 40 to 50°C.

Although the ceiling heating panel 10 described above can be placed over the entire ceiling, it is often placed partially in combination with normal panel materials.

However, when implementing the indoor heating method according to the present invention, the above-mentioned floor heating device is mainly used, and the above-mentioned ceiling heating panel is used in combination.

In other words, heating operation starts by activating the floor heating system,
If the indoor temperature is below the set value, the ceiling heating panel 10 is driven to heat and keep warm. If the indoor temperature is above the set value, the ceiling heating panel 10 is stopped and only the floor heating system is used to heat and maintain the temperature. Keep warm.

In this case, the on/off set temperature (indoor temperature) and operation (control) mode of the ceiling heating panel need not be limited to a single mode, but multiple operation modes should be prepared and configured so that they can be switched to the desired mode. be able to.

According to the indoor heating method described above, when using a latent heat type floor heating device, a heat radiation type ceiling heating panel is also used, so that detailed temperature adjustment can be performed quickly and easily.

For example, when you want to heat a room at a higher temperature (e.g. 23 to 25 degrees Celsius) than the standard temperature (e.g. 20 degrees Celsius), when the climate conditions suddenly change and the indoor temperature drops below the standard temperature, or even when the indoor temperature is stopped for a long time When the temperature has completely fallen and it takes time to start up using only the floor heating device, this can be easily handled by turning on the ceiling heating panel 1o.

In addition, it is possible to design the floor heating device to have a small heat capacity and turn on the ceiling heating panel when the capacity is insufficient from time to time, thereby reducing equipment costs and running costs.

Furthermore, since the ceiling heating panel 10 of the heat radiation type is also used, the indoor space can be heated directly and quickly, and the phenomenon of downward convection of cold air along the glass surface that forms the boundary with the outside air, that is, cold draft. By preventing this, uniform and comfortable heating can be achieved.

In addition to the heat radiation type ceiling heating panel 10 that incorporates a planar heating element 15 as shown in the figure, for example, a ceiling material such as a gypsum board with heat generating wires (usually coated wires) such as nickel chrome wires is used. Various structures can be used, including embedded structures.

Furthermore, the structure of the floor heating system is not limited to the one shown in the diagram; various structures can be adopted, such as a structure in which a unit is installed between floor joists and a floorboard is placed on top of it. can.

〔effect〕

As is clear from the above description, according to the present invention, a latent heat type floor heating device and a thermal radiation type ceiling heating panel are installed together, and when the room temperature is heated by the floor heating device, the room temperature is below a set value. Since this is detected and the ceiling heating panel is driven, it is possible to easily adjust the room temperature while maintaining economical efficiency, and to provide an indoor heating method that can improve startup performance at the start of heating.
