[0002]

2. Description of the Related Art A hot water type hot water heating mat is known as a heating device for floor heating such as flooring. Figure 7
And FIG. 9 shows an example of the hot water heating mat 1. The hot water heating mat 1 includes a mat base material 2 as a device base material formed by forming a heat insulating foam base material such as plastic into a plate shape. A plurality of small joists 3 as aggregates are arranged at intervals, and a hot water connection header (connection header) 4 installed in the center of one side of the square mat base material 2 is used as a hot water inlet / outlet, One or more, in the example of FIG. 7, two hot water circulation pipes (circulation pipes) 5a, 5b bypass the small joist 3 and are laid around the U-turn portion 55.

As shown in FIG. 8, the hot water connection header 4 is divided into a header 6 on the hot water supply side and a header 7 on the hot water return side.
The inlet sides of a and 5b are connected, and the header 7 side is connected to the outlet sides of the hot water circulation pipes 5a and 5b. In general, the two hot water circulation pipes 5a and 5b bypass the small joist 3 from the header 6 side and make a U-turn part, as shown in FIG.
After being routed to the half side of the mat substrate 2 via 55 and folded back, the other half side of the mat substrate 2 is similarly routed and returned to the header 7 and laid in parallel. In addition, if necessary, the heat radiation surface side of the mat base material 2 may be
As shown in FIG. 9, an aluminum foil 8 as a heat dissipation material is stretched.

When this hot water heating mat 1 is installed and constructed, as shown in FIG. 9, for example, the hot water heating mat 1 is laid above the floor panel 10 of the flooring room. Then, the flooring material 11 is put on the upper side of the mat 1 and the nails 12
To fix the flooring floor material 11 to the joist 13 (
Is fixed to the floor material 11). Then, as shown in FIG. 7, the outward pipe 14 is connected to the header 6 side, the return pipe 15 is connected to the header 7, and the external hot water circulation of the heat source device 9 including the outward pipe 14 and the return pipe 15 is performed. The passage (external circulation passage) 16 and the hot water circulation pipes 5a and 5b were connected via the hot water connection header 4.

Floor heating of the flooring is performed by circulating hot water, which is a temperature control medium, from the heat source 9 through the external hot water circulation path 16 to the hot water circulation pipes 5a, 5b of the hot water heating mat from the hot water circulation pipes 5a, 5b. Is radiated from under the floor of the flooring and transmitted to the flooring floor material 11.

[0006]

However, in the conventional hot water heating mat 1, the hot water circulation pipes 5a and 5b are used.
Since the hot water sent from the heat source device 9 is first passed through the half side of the mat 1 to radiate heat and then passed through the other half side of the mat 1 for heating, the hot water of the mat 1 through which the hot water first passes. The floor area can be heated relatively efficiently in the half side area, but the remaining half of the mat 1 has almost all the radiated return water, so the amount of heat radiated is small and the heating efficiency is high. Therefore, there is a problem in that temperature unevenness (temperature difference) occurs between the one-side half area and the other-side half area of the hot water heating mat 1.

Particularly, when a large-sized hot water heating mat 1 having a large area is laid, the temperature unevenness between the one-side half region and the other-side half region becomes large, and the floor surface of the flooring cannot be heated uniformly over a wide range. There was a problem. The inventor measured the temperature difference between the left and right sides of the mat 1, and, for example, supplied hot water of 80 ° C. to 90 ° C. from the heat source device 9 and operated the heating temperature of the floor surface to be approximately 25 ° C. However, it was confirmed that there was a temperature difference of 7 ° C between the first half of the hot water and the remaining half of the hot water return side. Results in too much heat and too cold in the return area, making it extremely difficult to heat the entire area of the hot water heating mat 1 at a comfortable and uniform temperature, which is an obstacle to providing a comfortable living environment. It was

The present invention has been made to solve the above problems, and an object thereof is to provide uniform and uniform temperature distribution over the entire area of a large-sized cooling / heating device having a large area.

A circulation pipe is laid around the turn header to return to the connection header side, and at least the direction of the flow of the temperature control medium passing through the plurality of adjacent circulation pipes passes through the half side of the device substrate. Adjacent ends of each circulation pipe are connected to the medium supply connection port and the medium return connection port of the connection header so that the flow and the return flow through the other half of the apparatus substrate are in the opposite direction.

Flow and the return flow through the other half of the device substrate are opposite to each other, so that both ends of the circulation pipe are connected to the medium supply connection port and the medium return connection port of the connection header. The occurrence of temperature unevenness between the half side of the material and the other half side is suppressed, and the amount of cold / warm heat radiated over the entire area of the cooling / heating device is substantially equalized. Then, at least the temperature adjusting surface of the U-turn portion of the return-side circulation pipe in which the temperature adjusting medium flows in the returning direction is covered with a radiator to cover the heat-dissipating surface side of the U-turn portion. The heat dissipation efficiency of the cold and warm heat radiated in the defective area is improved, and the temperature on the heat dissipation surface side of the poor temperature control area of this U-turn part locally rises or falls, resulting in poor temperature control. It is suppressed, and the comfortable cooling and heating of the floor and the like is achieved at a uniform temperature without temperature unevenness over the entire area of the cooling and heating device.

In the hot water heating mat 20 of this embodiment,
Hot water connection header 21 built into the hot water heating mat 20
2 to 4, the one end sides of the two hot water circulation pipes 5a and 5b laid in parallel are provided with hot water return connection port 46 and hot water supply connection port 38, respectively. Of the mat base material 2 are alternately connected so as to have a reverse flow of a forward flow passing through the half side of the mat base material 2 and a return flow passing through the other half side of the mat base material 2. By alternately connecting the other ends of 5a and 5b to the hot water supply connection port 39 and the hot water return connection port 47, respectively, so that the direction of the flow of hot water is opposite to the direction of the forward flow and the direction of the return flow. On the left half side of the hot water heating mat 20 shown in FIG. 1, the hot water circulation pipe 5a side becomes the hot water flow direction of the forward side, and the hot water circulation pipe 5b side becomes the hot water flow of the return direction. On the half side, the warm water circulation pipe 5a side is warm water in the return direction. Become a flow, hot water circulation pipe 5b is the hot water of the forward side of the flow.

In this way, the hot water circulating pipes 5a, 5b on the one half side (left side in FIG. 1) and the other half side (right half side in FIG. 1) on one side of the hot water circulation mat 20 pass through the adjacent hot water circulation pipes 5a, 5b. The flow direction of the mat is always opposite to the forward flow passing through the half side of the mat substrate 20 and the returning flow passing through the other half side of the mat substrate 20. The hot water circulation pipes on the half side of both of the hot water circulation pipes are the outgoing hot water flows, and the hot water circulation pipes 5a and 5b on the other half side of the hot water heating mat are both the hot water flowing in the same direction. However, the flow of hot water in the opposite direction is always generated in the adjacent hot water circulation pipes 5a, 5b, and as a result, the hot water circulation pipes 5a, 5b on one half side and the other half side of the hot water heating mat 20 are connected. Total release of The amount is approximately equal.

Further, the U-turn portions 55a, 55b of the return port side hot water circulation pipes 5a, 5b in which the hot water flows in the returning direction.
Since the direction of the hot water flowing through the hot water circulation pipes 5a, 5b is the direction of the return flow, the temperature control by the hot water as the temperature control medium is poor and the temperature becomes locally low, so that the U-turn portion 55a, A low temperature region is formed at 55b. In particular, the small joists 3 are generally made of plastic, wood, etc., and have low heat dissipation efficiency.
The temperature unevenness is likely to occur locally on the upper side (heat radiation surface side) of the U-turn portion 55a sandwiching the U-turn portion 55a.
Since the heat radiation surface side of the low temperature region of a and 55b is covered with the aluminum foil 18, the heat radiation efficiency of the amount of heat radiated in this low temperature region is improved, and as a result, the upper temperature of the low temperature region is locally lowered. Is suppressed.

From the above, in the present embodiment, the temperature unevenness due to heating is not generated in the left and right regions of the hot water heating mat 20, and the local temperature unevenness is not generated, and the large area having a large area is provided. Even when the hot water heating mat 20 is laid, uniform floor heating can be performed without temperature unevenness over the entire area of the mat 20, and a comfortable living heating environment can be created.

FIG. 5 shows, as a second embodiment of the cooling / heating apparatus of the present invention, a configuration example of a hot water heating mat having a configuration different from that of FIG. This embodiment is different from the first embodiment in that the aluminum foil 18 is placed in a high temperature region (temperature control good region) adjacent to a low temperature region (temperature control poor region) of the U-turn portions 55a and 55b. In this way, the heat-radiating surface side (upper side) of the U-turn low-temperature region is covered by being expanded and expanded in this way. The high temperature region is formed by laying outward hot water circulation pipes (outward circulation pipes) 5a and 5b through which hot water flows in the forward direction. The configuration of this example other than the above is the same as that of the first example.

This embodiment is constructed as described above,
Also in this embodiment, the same effect as that of the first embodiment is obtained, and further, in this embodiment, the covering with the aluminum foil 18 is performed.
By expanding and expanding to the high temperature region adjacent to the low temperature regions of the U-turn parts 55a and 55b, the heat of the high temperature region is stored by the aluminum foil 18 and radiated on the low temperature region side, and the upper temperature of the low temperature region becomes low. This can be effectively suppressed, and uniform floor heating without temperature unevenness can be performed over the entire area of the hot water circulation mat 20.

The present invention is not limited to the above-mentioned embodiment, and various embodiments can be adopted. For example, when the hot water connection header 21 is formed, in the hot water connection header 21 shown in FIG. 2, the passage of the modified Y-shaped pipe 24 is used as the forward passage and the internal space of the box body 31 is used as the return passage.

In the above embodiment, the two hot water circulation pipes 5a and 5b are laid on the hot water heating mat 20, but three or more hot water circulation pipes may be laid. In this case, according to the number of hot water circulation pipes, the deformation Y
By increasing the number of branch opening ends (pipe opening ends) of the V-shaped pipes 24, 24a, 24b and the T-shaped pipes 50, 51, in the case of the hot water connection header shown in FIG. Similarly, the number of box connection ports to be provided will be increased. In this way, even when the number of hot water circulation pipes is increased, the hot water connection headers are arranged so that the hot water flows of the adjacent pipes are opposite to each other at both ends of the hot water circulation pipe group, as in the above-described embodiment.
21 hot water supply connection ports and hot water return connection ports will be connected alternately.

Further, in the above-mentioned embodiment, at least the heat radiation surface side of the U-turn portions 55a, 55b of the hot water circulation pipes 5a, 5b in the low temperature region is covered with the aluminum foil 18 as the heat radiator, but the heat radiator is not necessarily the aluminum foil. The material is not limited to 18, and may be a material such as copper other than aluminum, and may be a plate material having a thickness slightly larger than that of the foil.

Further, in the hot water heating mats as in the first and second embodiments, as shown in FIG. 9, aluminum foil may be used over the entire area of the mat base material 2 on the heat radiation surface side, if necessary. 8 may be stretched. Thus, even when the aluminum foil 8 is stretched over the entire area on the heat radiation surface side, at least the hot water circulation pipe 5 is provided, as in the above embodiment.
By additionally coating the aluminum foil 18 on the upper side of the U-turn portions 55a, 55b of a, 5b in the low temperature region (heat radiation surface side of the low temperature region), the aluminum foil 18 is covered in the coating region of the aluminum foil 18. Since it is possible to improve the heat dissipation efficiency as compared with the non-existing region, it is possible to obtain the same effect as that of the above embodiment.

Further, in the above embodiment, the hot water connection header
The reference numeral 21 accommodates the deformed Y-shaped pipe or the T-shaped pipe in the box body 31 to form the outward passage or the return passage, but the outward passage is formed by using a pipe having a shape different from the modified Y-shaped or T-shaped pipe. It is also possible to form a return passage in the box 31.
When using a modified Y-shaped pipe, for example,
As shown in FIG. 3A and the broken line in FIG. 4, it is possible to use modified Y-shaped pipes having different shapes.

Further, in the above embodiment, the box body 31 of the hot water connection header 21 is a flat quadrangular body, but it may be a flat polygonal box body other than a quadrangle as shown in FIG. 6, or It may be a flat circular or elliptical box. Further, the box does not necessarily have to be flat.

Further, the box body 31 of the hot water connection header 21 incorporated in the hot water heating mat 20 is formed by using metal such as stainless steel or other metal material, but the box is formed by using material other than metal, for example, plastic material. It is also possible to form the body 31. Further, the deformed Y-shaped or T-shaped pipe material to be housed in the box body 31 is usually formed by using a metal material having excellent thermal conductivity such as copper. It is also possible to form the hot water circulation pipes 5a and 5b by using a metal material having excellent thermal conductivity such as copper, or by using a material other than metal such as plastic. It can also be formed by using.

Further, although the mat base material 2 has a quadrangular shape, it may have any other shape. In the embodiment, the hot water connection header 21 is arranged at the center of one side of the mat base material 2. The installation position does not necessarily have to be provided at the center of one side, but can be provided at another appropriate position according to the specifications.

Further, in the above-mentioned embodiment, the hot water heating is described as an example, but cooling water is radiated from the circulation pipes 5a and 5b by circulating and supplying water which is not heated or cooled water from the heat source device to perform cooling. You can Also in this case, as in the case of heating, the amount of heat radiation in the one-side half region and the other-side half region of the mat base material 2 is balanced, and uniform floor cooling without temperature unevenness can be achieved over the entire mat surface.
