Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel unit for cooling and heating provided on a floor, a wall, a ceiling or the like by integrating a pipe unit for heating and cooling.

[0002]

2. Description of the Related Art Conventionally, as a heating pipe unit used in a so-called floor heating apparatus, Japanese Patent Application Laid-Open No. H11-24817 has been disclosed.
As disclosed in Japanese Patent Publication No. 8 (1994), a thick main pipe having a circular cross section is provided on the supply side and the return side of the warm water, and a thin heat exchange pipe is arranged in parallel between the circular main pipes. There is one in which a plurality of tubes are arranged so that hot water flows in parallel through a heat exchange pipe. In this case, the thick circular main pipe is disposed in a relief portion formed between the joist and the heat insulating material under the floor. Also, JP-A-11-28
As disclosed in Japanese Patent Publication No. 0239, there has been proposed an apparatus in which a concave portion is formed in a floor plate constituting a flooring to accommodate a part of a heat exchange pipe or a main pipe.

[0003]

In the case of the above-mentioned prior art, since the outer diameter of the circular main pipe is large, a space is provided by forming a concave portion in a joist or a heat insulating material under the floor.
There are problems that the man-hour for forming the concave portion is required and that the strength of the joist is reduced by forming the concave portion.

Further, there is a case where air in the main pipe stays without escaping due to a difference in outer diameter between the circular main pipe and the plurality of heat exchange pipes. This is because a portion higher in height than the heat exchange pipe is formed on one side of the main pipe that is thicker than the heat exchange pipe, and air tends to remain in that portion. If the air remains in the main pipe in this manner, the fluidity of hot water as a heat exchange fluid in the main pipe decreases, and it becomes difficult for hot water to go downstream, and uneven temperature occurs on the floor surface. It was a mess. Further, when the space of the air in the main pipe becomes large, there is a problem that the air becomes a heat insulator and the heat radiation of that portion is reduced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has a good workability, can shorten a work period, and is less likely to cause surface temperature unevenness. The purpose is to provide.

Since it is provided integrally with the base material 26, the joist 34,
There is no need to form recesses or holes other than the through holes 37 in the heat insulating material 36 or the like, and it is not necessary to perform any other special foundation work.
Extremely good workability. Moreover, since a finish material such as an existing decorative panel 6 which is conventionally used is used, there is no step between the place where the cooling / heating panel unit 2 is constructed and the place where the panel unit 2 is not constructed, and the conventional floor heating work and the like are not performed. It can be greatly simplified as compared with. Also, when installing on the floor, wall, ceiling, etc. of an existing house, the old finishing material on the indoor side is removed and through holes 37 for the connectors 14 and 16 are formed in the base material 26, so that the under floor, the back of the wall, It can be constructed simply by connecting the connection hose 38 behind the ceiling or the like, and does not require large-scale construction and can be installed at low cost. Further, since the heat exchange pipe 18 is located close to the surface of the decorative plate 6 or the like which is a finishing material, the heat exchange efficiency is good, and the main pipes 10 and 12 are flattened to have a sufficient cross-sectional area. Since air can hardly remain in the main pipes 10 and 12, cooling and heating without temperature unevenness can be performed.

In particular, the panel unit 2 for cooling and heating
Main pipes 10, 1 for supply and return of heat exchange fluid
2 and the heat exchange pipe 18 for heat exchange, thereby achieving the contradictory issues of thinning and improvement of heat exchange efficiency. That is, the main pipes 10, 12
The pipe diameter is large and a sufficient flow rate can be obtained, and the heat exchange pipe 18 for performing heat exchange with the room is connected to the main pipe 10 which is a heat exchange fluid supply source, for example, in the case of a standard finishing material. The maximum is about 1.7 m, the pressure loss in the heat exchange pipe 18 is small, and a sufficient flow rate can be obtained. Furthermore, a large number of heat exchange pipes 18 can be arranged in parallel with the main pipes 10 and 12, the number of heat exchange pipes 18 per unit area is large, and the heat exchange fluid flows sufficiently, so that extremely high heat exchange pipes are provided. Efficiency is obtained. In addition, since the flow rate is large, the cooling and heating effect can be quickly obtained, and the cooling and heating without temperature unevenness can be performed. On the other hand, in the case of an apparatus in which a single pipe is meanderingly arranged on the back surface of the floor, which is conventionally used for general hot water floor heating, the density of the pipeline will be increased in order to increase the heat exchange efficiency. Then, the pipe line becomes long, the pressure loss is large, and a sufficient flow rate of the heat exchange fluid cannot be obtained, and the pipe diameter must be increased in order to increase the flow rate. It is impossible to place them. Further, when the pipe is long, a temperature difference occurs between the upstream side and the downstream side. However, in the cooling and heating panel unit 2 of this embodiment, one heat exchange pipe 18 is relatively short,
The difference in temperature hardly occurs depending on the location.

Next, a cooling and heating panel unit 42 according to a second embodiment of the present invention will be described with reference to FIGS. Here, the same members as those in the above embodiment are denoted by the same reference numerals, and description thereof will be omitted. This pipe unit 44

A relay main pipe 45 is provided. The relay main pipe 45 includes main pipes 46a and 46b.
It has approximately the same cross section and length, and both ends are closed. Then, the main pipes 46a, 46
b and the main pipe 45 are the 14 heat exchange pipes 18
Are connected by In this embodiment, the same decorative board 6 as in the first embodiment can be used.

The cooling and heating panel unit 42 of this embodiment
According to this, the connection of the heat exchange fluid can be performed on the same side of the decorative plate 6, and the piping can be simplified.
