Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a temperature control device for a building that uses a heat pipe to transfer outdoor heat or high-temperature indoor heat to a room that requires heating.

In a typical building, rooms on the south side of the building that receive direct sunlight are usually warm and rooms on the north side of the building are cold. The warm air inside the room is sent to the room on the north side. Therefore,
Electric power is required to drive the blower;
Noise is generated by driving the blower. Also, blowers deliver constant air regardless of temperature, making it difficult to control blowers automatically. Since the blower is used to send air, it also sends heat and odors, and since the room on the south side, where warm air is sent, has a negative pressure, there is a risk of cold drafts entering the room. Furthermore, the duct piping work for conveying the air is difficult, and the duct must be kept warm.

The object of this invention is to be able to automatically transfer outdoor heat or high-temperature indoor heat to a room that requires heating without using power, and to stop heat transfer as necessary. Our goal is to provide temperature control equipment for buildings.

The temperature control device according to the present invention includes a hollow heat absorption panel that is placed on the outdoor side or indoors on the high temperature side of a building and constitutes a heat pipe evaporation section, and a hollow heat absorption panel that is placed on the indoor side of the building that requires heating and constitutes a heat pipe condensation section. Consisting of a hollow heat radiation panel, a gas transfer pipe that connects the upper parts of the heat absorption panel and the heat radiation panel, a condensate transfer pipe that connects the lower parts of the heat absorption panel and the heat radiation panel, and a working fluid sealed inside these. It is equipped with a loop-shaped heat pipe, and the condensate transfer pipe is provided with an operation control valve, and when the operation control valve is closed, the part of the condensate transfer pipe on the heat radiation panel side of the operation control valve, the heat radiation panel, and the gas transfer The gas transfer pipe is characterized in that the gas transfer pipe is arranged with a lower slope on the side of the heat dissipation panel so that all the working fluid condensed in the pipe can be accommodated.

Since the temperature control device according to the present invention is equipped with a loop-shaped heat pipe as described above, it automatically transfers outdoor heat or indoor heat on the high temperature side to a room that requires heating, as follows. In addition, heat transfer can be stopped if necessary.
That is, by opening the operation control valve, the heat pipe operates normally, and the working fluid absorbs heat outdoors or indoors on the high temperature side within the heat absorption panel, evaporates, and passes through the gas transfer pipe into the heat dissipation panel. Move to
Heat is radiated and condensed within the heat dissipation panel into a room that requires heating, and the cycle is repeated by returning to the heat absorption panel through the condensate transfer pipe and operation control valve. and,
As a result, heat from the outdoors or indoors on the high temperature side is continuously transferred to the indoors that requires heating. Then, by closing the operation control valve, the working fluid that has evaporated inside the heat absorption panel moves into the heat radiation panel through the gas transfer pipe, and the working fluid that has condensed inside the heat radiation panel accumulates on the heat radiation panel side and flows inside the heat absorption panel. There's no going back. As a result, all the working fluid eventually reaches the part of the condensate transfer pipe closer to the heat dissipation panel than the operation control valve.
There is no working fluid in the heat dissipation panel and the gas transfer tube, and in the heat absorption panel, which stops the operation of the heat pipe, i.e., heat transfer. In this way, heat transfer can be started or stopped by an extremely simple operation of simply opening and closing the operating control valve. Further, since the temperature control device according to the present invention utilizes a heat pipe, it does not require power and does not generate noise. Furthermore, unlike conventional systems, which transport warm air from a high-temperature room into a room that requires heating, only heat is transported through a heat pipe, so there is no need to send odors, etc. at the same time. In addition, there is no negative pressure in the room on the high temperature side, so there is no risk of drafts entering the room. Also, since it does not send air,
No duct required.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a temperature control device installed between a room 2 on the south side (high temperature side) of a building 1 and a room 3 on the north side that requires heating.
A hollow heat absorption panel 6 is placed on the inner surface of the heat pipe 5, and the heat pipe 5 is placed inside the hollow heat absorption panel 6, which constitutes a heat pipe evaporation section.
, a hollow heat dissipation panel 8 disposed on the inner surface of the wall 7 of the north chamber 3 and forming a heat pipe condensing section, a gas transfer pipe 9 connecting the upper parts of the heat absorption panel 6 and the heat dissipation panel 8, and the heat absorption panel 6. It is provided with a loop-shaped heat pipe consisting of a condensate transfer pipe 10 connecting the lower parts of the heat radiation panel 8 and a working fluid (not shown) sealed inside these pipes.

As shown in detail in FIG. 2, the heat absorption panel 6 is
It is composed of a tube-on-sheet in which a plurality of vertical tubes 12 are joined to one vertical heat absorbing sheet 11, and the upper ends of these tubes 12 are connected to the lower part of the horizontal header pipe 13 of the gas transfer pipe 9. The lower end is connected to the upper part of the horizontal header pipe 14 of the condensate transfer pipe 10. Approximately 2/3 of the upper part of each tube 12 is filled with a cotton-like wick 5 made of, for example, glass wool, and the lower part of the wick 5 is the level of the liquid working fluid in the tube 12 during normal operation. (In this case, the position is about 1/2 of the height of the tube 12). Additionally, as shown in detail in Figure 3,
The upper end of the wick 5 is located slightly (for example, about 20 mm) below the header pipe 13 in the tube 12.

The heat dissipation panel 8 is non-wicking,
The structure is substantially the same as that of the heat absorption panel 6 except for this point.

The condensate transfer pipe 10 is disposed, for example, below the floor 15, either horizontally or with the side of the heat absorption panel 6 at a low slope. The angle of inclination (α) of the condensate transfer tube 10 with respect to the horizontal ranges from 0 to 60°, and although it is shown slightly exaggerated in FIG. 1, it is usually about 3°.
Further, the condensate transfer pipe 10 is provided with an operation control valve 16 .

The gas transfer pipe 9 is located above the ceiling 17, for example.
The heat dissipation panel 8 side is arranged in a low slope.
The inner diameter of the gas transfer pipe 9 and the inclination angle (β) with respect to the horizontal are determined by the portion of the condensate transfer pipe 10 closer to the heat radiation panel 8 than the operation control valve 16, the heat radiation panel 8, and the gas transfer pipe when the operation control valve 16 is closed. 9 to accommodate the entire working fluid condensed therein.
And, this inclination angle is 45 degrees or less, and the first
Although the figure shows it slightly exaggerated, it is usually 0.5~
It is about 1°.

Although not shown, two transfer pipes 9 and 1
0 is covered with insulation. Also, the north and south rooms 2,
A corridor 18 is provided between the rooms 3 and 3.

In the above-mentioned building 1, the interior of the room 2 on the south side receives sunlight directly, so it becomes relatively high temperature, and the interior of the room 3 on the north side becomes relatively low temperature. Then, the heat in the south chamber 2 is automatically transferred to the north chamber 3 by the temperature control chamber, and the temperature of these chambers 2 and 3 is adjusted as follows.

That is, when transferring heat, the operation control valve 16 is kept open. In this way, the working fluid in the heat pipe is distributed throughout the heat absorption panel by the capillary action of the heat pipe 5, and the working fluid in the heat pipe 5 is distributed throughout the heat absorption panel.
It absorbs the heat inside and evaporates. The gaseous working fluid evaporated within the heat absorption panel 6 is transferred to the gas transfer pipe 9
The heat moves through the heat dissipation panel 8, radiates heat into the room 3 on the north side, and condenses. The working fluid condensed within the heat dissipation panel 8 flows down within the panel 8, returns to the heat absorption panel through the condensate transfer pipe 10 and the operation control valve 16, and returns to the heat absorption panel 6 due to the capillary action of the wick 5. It spreads throughout and circulates in the same way as above. By operating the heat pipe in this way, the heat in the chamber 2 on the south side is continuously transferred to the chamber 3 on the north side, and in winter, the heat in the chamber 2 on the south side is transferred.
The interior of the room 3 on the north side can be heated by the heat transferred from inside, and in the summer, the interior of the room 2 on the south side can be cooled by transferring heat to the interior of the room 3 on the north side. can. At this time, since the heat pipe 5 is placed inside the heat absorption panel 6, the performance of the heat pipe is improved. 4 and 5 show the comparative test results with and without a wick, where the horizontal axis represents the temperature difference (°C) between the heat absorption panel 6 and the heat radiating panel 8; The vertical axis represents the amount of heat transfer (kcal/h).
FIG. 4 shows the condensate transfer pipe 10 horizontally.
Figure 5 shows the case where the inclination angle (α) is 0°, and the case where the inclination angle (α) is 3°. . Furthermore, by arranging the condensate transfer pipe 10 in an inclined manner with the endothermic panel 6 side being slightly lower, the performance of the heat pipe is improved. Figure 6 shows the test results comparing the case where the inclination angle (α) of the condensate transfer pipe 10 with respect to the horizontal is 0° and 3°, with the horizontal axis and vertical axis This is the same as FIGS. 4 and 5.
From FIG. 6, it can be seen that the amount of heat transfer is larger when the inclination angle (α) is 3° than when the inclination angle (α) is 0°. Note that the maximum heat transfer efficiency occurs when the inclination angle (α) is 60°.

When stopping heat transfer, the operation control valve 16 is closed. In this way, the working fluid evaporated within the heat absorption panel 6 moves into the heat radiation panel 8 through the gas transfer pipe 9, and the working fluid condensed within the heat radiation panel 8 accumulates on the heat radiation panel 8 side and the heat absorption panel 6
There is no going back inside. Therefore, all the working fluid eventually accumulates in the portion of the condensate transfer pipe 10 closer to the heat radiation panel 8 than the operation control valve 16, the heat radiation panel 8, and the gas transfer pipe 9, and there is no working fluid in the heat absorption panel 6. This stops the operation of the heat pipe, ie, the transfer of heat.

The heat absorbing panel 6 may be placed outdoors, for example, on the outer surface of the south wall of the building. In this way, by keeping the actuation control valve 16 open during the winter when there is sunlight during the day, solar heat can be continuously transferred indoors to heat the room. Then, at night during winter, the operation control valve 1
By keeping 6 closed, heat radiation loss from indoors to outdoors can be greatly reduced. Also,
When heating is not required, such as in the summer, by closing the operation control valve 16, the operation of the heat pipe, that is, the transfer of heat from the outdoors to the room, can be stopped, thereby preventing the indoor temperature from rising due to solar heat. can.
