Abstract

PURPOSE:To effect comfortable heating regardless of the structure and configuration of a room by a method wherein a hot air type or radiation type auxiliary heat radiator is provided in parallel and the temperatures of respective floor surfaces are detected while the heat radiation of the auxiliary heat radiator is effected to the floor surfaces having low temperatures. CONSTITUTION:Upon applying the title system, an auxiliary heat radiator 8 is operated toward a floor surface 6 without floor panel 5. When a given time (about 30 minutes) has elapsed, the floor surface temperature T3 of a floor surface 6 without floor panel 5, is detected by an infrared ray sensor 9 and the detected value is stored in a controller. When floor heating operation is started thereafter, the infrared ray sensor 9 detects the temperature T0 of the floor surface 6 upon the starting of the operation at first and, thereafter, the radiation of the auxiliary heat radiator 10 is started toward the floor surface 6. Subsequently, the temperature T1 of the floor panel 5 is detected by the infrared ray sensor 9. Subsequently, the temperature T2 of the floor surface 6 is detected again. These operations are repeated and the auxiliary heat radia tor is stopped when T1 T2 or T0 T2. Heating may be effected comfortably regardless of the configuration or the like of a room in such a manner.

Description

[Detailed description of the invention] Purpose of invention] (Industrial application field) The present invention relates to a floor heating system.

(Prior Art) Conventionally, a floor heating system is known in which a plurality of floor panels each having a heat medium passage or a heat source inside are installed and heating is performed by conduction, radiation, etc. via the floor surface. As a means of heating floor panels.

Usually, heat pump methods use piping installed inside the floor panel as a condenser, methods that flow hot water through the piping, and methods that bury electric heaters inside the floor panels.

Methods such as placing heat storage material inside the floor panels are being adopted. Because the elements necessary for heating are buried within the floor panel, it is difficult to manufacture a floor panel with a variable shape. Therefore 1 usually.

A method is used in which multiple types of floor panels with standardized sizes are prepared, and at the time of construction, the standardized floor panels are combined and laid according to the size and shape of the floor at the installation location.

However, the floor heating system configured in this manner has the following problems.

In other words, the size and shape of the floors in one room usually vary. For this reason, even if a plurality of standardized types of floor panels are combined, there are often places where these floor panels cannot be installed. If there is a place in one room where a floor panel cannot be installed, there will be a large difference in floor temperature between the installed place and the non-installed place, and this will cause a problem in which comfort will be impaired.

(Problems to be Solved by the Invention) As mentioned above, with conventional floor heating systems, it is difficult to create a comfortable heating form depending on the structure and shape of the room.

Therefore, an object of the present invention is to provide a floor heating system that can create a comfortable heating mode regardless of the structure or shape of a room.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, a floor heating system according to the present invention includes a plurality of floor panels each having a heat medium passage or a heat source therein. An auxiliary heat radiator that radiates heat toward the floor surface by hot air or radiation in a device that provides heating through a surface.

A variable mechanism that changes the direction of heat radiation of this auxiliary heat radiator.

temperature detection means for detecting the temperature of each part of the floor surface;

and means for controlling the variable mechanism to cause the auxiliary radiator to radiate heat toward a lower temperature floor surface area based on the temperature detected by the temperature detection means.

(Function) The temperature of the floor surface differs between locations where floor panels equipped with the elements necessary for heating are installed and locations where they are not installed. This difference is determined by the output of the temperature detection means. and,
Heat is radiated from the auxiliary radiator toward areas with lower floor surface temperatures. Therefore, the entire floor surfaces of the seven rooms are kept at approximately the same temperature.

(Example) An embodiment will be described below with reference to one drawing.

FIG. 1 shows a conceptual diagram when a floor heating system according to an embodiment is installed in a certain room.

In the figure, 1 indicates a room, 2 indicates a partition,
3 indicates the floor. In this example, the target room 1 is different from a normal room, and has a shape in which one corner 4 is cut off.

On the floor 3 of the room 1, a plurality of floor panels 5 are laid in close contact with each other in accordance with the shape of the floor 3, each of which is formed into a standard size with, for example, a heat medium flow pipe embedded therein. In addition,
The floor area adjacent to corner 4 is.

Since it is not possible to install a standard-sized floor panel 5 due to space constraints, a floor panel 6 with no heat medium flow pipe buried inside is installed in this area simply to match the height. ing. And these floor panels 6.5
A single carpet is laid on the top surface of the building to cover them in common. Further, nine heat medium flow pipes buried in each floor panel 5 are connected in series or in parallel to be selectively connected to a heat medium supply source 7 shown in FIG. 2.

On the other hand, an auxiliary heat radiator 8 is installed on the inner surface of the partition 2, which radiates heat toward the floor by hot air or radiation.
In addition, there are infrared sensors 9 on the ceiling that detect the temperature of various parts of the floor.
is installed.

As shown in FIG. 2, the auxiliary radiator 8 includes an auxiliary radiator main body 10 that generates heat, and a direction-variable guide mechanism that radiates the heat generated in the main body 10 to an arbitrary location on the floor surface. 1
1, and a control device 12 that controls the angle of this guide mechanism 11.
It is made up of.

The control device 12 operates in accordance with the operation of the heat medium supply [7].
This is to compare the temperature of each part of the floor surface based on the output of the infrared sensor 9, which will be described next, and to control the angle of the guide mechanism 11 so that heat is radiated to a place with a lower temperature. It works like that.

On the other hand, the infrared sensor 9 is of a scanning type, and the control device 12
It operates according to the relationship described below based on the control signal from.

Next, an example of use and operation of the floor heating system configured as described above will be described with reference to flowcharts shown in FIGS. 3 to 5.

First, during construction, the guide mechanism 11 of the auxiliary radiator 8 is directed toward a so-called uninstalled location where the floor panel 5 is not installed.

In this state, the auxiliary radiator 8 is started (Sl, S2
). When 30 minutes have passed from the start of operation (S3),
The control device 12 uses the infrared sensor 9 to detect the floor surface temperature T3 of the uninstalled area, that is, the part where the floor panel 6 is installed, and stores this value in the built-in storage device (S4
). The above are the operations and actions required during construction.

Next, in the season when heating is required, when the heating medium supply source 7 is activated to start floor heating operation (S5), the control device 12
operates, and the infrared sensor 9 starts operating accordingly (
Si2), and the temperature To of the non-installed location at the time of starting the floor heating operation is detected (S7). This temperature value is
It is stored in the storage device within 2.

Next, turn the heat radiation direction toward the uninstalled location, and then
0 starts the operation (S8). Next, the detection direction of the infrared sensor 9 is directed toward the installation location (89), and the floor surface temperature Tl of the portion where the floor panel 5 is installed is detected (SIO).

Subsequently, the detection direction of the infrared sensor 9 is directed toward a non-installed location (311), and the floor surface temperature T2 of the portion where the floor panel 6 is installed is detected (T12).

This detected temperature T2 is compared with the previously detected temperature T1 of the installation location (513), and if it is almost equal, it is determined that the temperature of the non-installation location has risen sufficiently, and the auxiliary radiator body 10 is operated. Stop (314>
. Also,? If A degree T and temperature T2 are not substantially equal, the already detected temperature T is reached after another 30 minutes (S15).

Compare and temperature T2 (81B). If both temperatures are almost equal, something is placed in the uninstalled location.

It is determined that there is no need to raise the temperature of this location, and the operation of the auxiliary radiator body 10 is stopped (Si2).

Further, when there is a large difference between the temperature To and the temperature T2, the temperature T3 stored in the storage device in the control device 12 is compared with the temperature T2 (S18). And when both temperatures are almost equal.

It is determined that the temperature at the non-installed location has not risen again, and the process returns to step S8 to restart execution. On the other hand, if there is a large difference in temperature between the two, the infrared sensor 9 scans the uninstalled area to detect the temperature of each part (S19). Then, the temperature of each part in the uninstalled place is compared with the temperature To, and if there is a place that is almost equal to To, it is determined that an object is placed at this place. The location where no is placed is newly set as an uninstalled location (S21), and the process returns to step S8 to restart execution. Therefore, in a place where the floor panel 5 is not installed.

The floor surface that is actually used for living will be maintained at approximately the same temperature as the floor surface on which the floor panel 5 is installed.

Comfort can be significantly improved.

In addition, if a human pump for both heating and cooling is used as the heat medium supply source 7, and the heat medium is configured to flow through the piping arranged in the floor panel 5 and the auxiliary radiator main body 10 during heating, the entire system will be greatly improved. It can be simplified.

[Effects of the Invention] As described above, according to the floor heating system according to the second invention, it is possible to reliably prevent a decrease in comfort that tends to occur when the size of the floor panel equipped with the elements necessary for heating is standardized. be able to.
