TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cooling / heating device for flowing a cooling or heating fluid through a fluid flow path provided in a panel body.
[0002]
[Prior art]
2. Description of the Related Art A conventionally known air conditioner that circulates a fluid lays a pipe on its panel body and cools or heats the panel body with the fluid circulated through the pipe. The intended cooling or heating effect is obtained by the radiant heat transfer of the cooled or heated panel body and the convective heat transfer of the air in contact with the panel body.
[0003]
[Problems to be solved by the invention]
In the conventional cooling and heating device as described above, for example, when the panel main body is installed on the ceiling, the heat transfer surface of the panel main body is only the surface facing the room. In other words, the surface of the panel body facing the ceiling side is not effectively used as the heat transfer surface. For this reason, the area of the heat transfer surface is reduced, and there is a problem that the cooling or heating efficiency is deteriorated accordingly.
An object of the present invention is to provide a cooling and heating device capable of effectively functioning both surfaces of a panel body as heat transfer surfaces.

[Means for Solving the Problems]
According to a first aspect of the present invention, a panel body provided with a fluid flow path through which a fluid flows is formed with a large number of air flow holes penetrating the panel body to allow the fluid to flow through the fluid flow path and to allow air to flow through the air flow hole. Is characterized in that it is made to be distributed.
The second invention is characterized in that a pipe is laid on one surface of the panel main body, and this pipe is used as a fluid flow path.
The third invention is characterized in that a fluid flow path is formed in the panel body.
The fourth invention is characterized in that a blower for forcibly flowing air is provided from one surface of the panel body to the other surface.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
In the illustrated embodiment, a panel body a made of aluminum has a plurality of pipe guide grooves 1 formed on one surface thereof in parallel with a constant interval. The hollow portion 2 sandwiched between the pipe guide grooves 1 has a large number of air flow holes 3 formed in the longitudinal direction of the hollow portion 2.
[0007]
Then, the heat radiating pipe 4 of the pipe mat m is fitted into the pipe guide groove 1, and the configuration of the pipe mat m is as follows. That is, the pipe mat m is such that a plurality of thin heat radiating pipes 4 are provided in parallel between a pair of thick main pipes 5 and 6 at a constant interval. It is set equal to the interval between the grooves 1. Therefore, when the pipe mat m is placed on the panel body a, the heat radiating pipe 4 of the pipe mat m necessarily coincides with the pipe guide groove 1. The pipe mat m constitutes the fluid flow path of the present invention.
[0008]
The pipe mat m as described above supplies a fluid from one main pipe 5, and the fluid supplied from the one main pipe 5 flows to the other main pipe 6 via the heat radiating pipe 4, From there, it is returned to a fluid supply source (not shown).
[0009]
When laying the panel body a on the ceiling, it is as shown in FIG. That is, one surface of the panel main body a in which the pipe guide groove 1 is formed is positioned on the ceiling wall 7 side. A blower 8 is used for the ceiling pocket 7 as a blower for forcibly flowing air. Then, while the outlet 8a of the blower 8 is located on the side of the ceiling wall 7, the suction port 8b of the blower 8 is located on the indoor side. Accordingly, when the blower 8 is driven, the air in the room is sucked and blown out to the ceiling pocket 7, and the blown air is forcibly blown out to the room side through the air circulation hole 3.
Note that the suction port 8b may be located in a ventilation passage formed of a duct, a space behind the wall, or the like, and the ventilation passage may be opened near the floor. If the ventilation passage is opened near the floor in this manner, the air jetted from the ceiling is sucked in from the floor, so that the air can be efficiently circulated throughout the room.
[0010]
Since the air is forcibly circulated by the blower 8 as described above, the air that has been heat-transferred on one surface of the panel body a facing the ceiling wall 7 is supplied to the indoor side. Therefore, both sides of one side and the other side of the panel main body a become heat transfer areas. As described above, since both surfaces of the panel main body a have a heat transfer area, the thermal efficiency thereof is remarkably improved as compared with a conventional apparatus in which only one surface can have a heat transfer area.
Further, a large number of air circulation holes 3 are formed in the panel main body a, and air is blown out toward the indoor side through the air circulation holes 3. Air heat transfer takes place. Therefore, the heat transfer area can be further increased, and the thermal efficiency can be improved accordingly.
[0011]
Furthermore, if air is blown out through the air circulation holes 3, the air inducing action works on the other surface of the panel body a facing the room. That is, on the other surface, the indoor air is drawn to the air circulation holes 3. Then, heat is transferred to the drawn air on the other surface of the panel body a facing the room. Therefore, on the other side, the heat transfer coefficient is increased, and the thermal efficiency of the entire panel body a can be further improved.
It should be noted that as the wind speed passing through the air flow holes 3 increases, the attracting action also increases accordingly. In addition, if the diameter of the air circulation hole 3 is small, the wind speed increases even if the air volume is the same, and the attracting action also increases. That is, by increasing the wind speed when passing through the air circulation holes 3, the thermal efficiency of the panel main body a can be further improved.
[0012]
In this embodiment, the case where the panel main body a is provided on the ceiling has been described. However, it is obvious that the panel main body a may be provided on a wall surface or a floor surface. However, when the panel main body a is provided on a wall surface or a floor surface, a space through which air flows must be formed behind the panel main body a.
[0013]
Although the blower 8 is used as the blower, the invention is not limited to this. For example, any device such as an external air conditioner or a dehumidifier can be used as long as air can be forcibly distributed.
Further, although the panel body a made of aluminum is used, it is made of aluminum because it has excellent thermal conductivity. Therefore, another metal or slate plate having excellent heat conductivity may be used as the panel body a. However, aluminum is preferable in consideration of weight reduction.
[0014]
Further, the heat radiation pipe 4 of the pipe mat m is laid in the panel main body a to provide a fluid flow path, but a single pipe may be provided in the panel main body a so as to meander. In this case, it is necessary to form an air flow hole other than where the pipe is located so that the air flow hole is not blocked by the pipe. In any case, the pipe provided in the pipe main body a may be of any type, and it is essential that the pipe has a function of circulating a cooling fluid or a heating fluid. Further, a hole as a fluid flow path may be directly formed in the panel main body a.
[0015]
【The invention's effect】
According to the cooling and heating devices of the first to third aspects, since both surfaces of the panel main body can be used as the heat transfer area, the thermal efficiency can be dramatically improved.
According to the cooling and heating device of the fourth invention, the air is forcibly circulated on both sides of the panel body, so that the thermal efficiency is further improved.
