2. Description of the Related Art Conventionally, air conditioners for large-scale buildings such as theaters control the temperature of the air in the entire space, or blow the conditioned air horizontally through a nozzle to control the temperature of the air in the vicinity of the living area. It is carried out. For example, in the theater, the outlets are formed near the ceiling and the side wall near the floor, and it is assumed that the conditioned air will flow evenly to the spectator seats from here, and the temperature and humidity of the spectator seats will be adjusted appropriately. Generally, the structure is as follows.

However, when air conditioning is performed only by controlling the temperature of the air, the target area is a large space, so it is necessary to send in a large amount of air, which makes the air conditioner and duct larger. Inevitably, there will be an unreasonable amount of time with the construction plan, which often causes uneven temperature and draft noise. Further, since the temperature of the entire space is adjusted, there is a drawback that energy loss is large. That is, since the temperature control is performed even in a space that does not require temperature control as compared to the area required for temperature control, it is not possible to perform efficient temperature management, and the time until the temperature and humidity reach an appropriate value can be obtained. There was a problem that it took a lot.

According to the above construction, the heat pipe is stretched around the floor such as the seats of the audience, and one end of this heat pipe is connected to the cold / hot water header. When heating is performed, hot water is flowed through the header to heat the header side heat pipe. The evaporative medium in the heat pipe transfers heat and dissipates the heat in a target area such as an audience seat. As a result, heating is performed. In the case of cooling, cooling water is made to flow through the hot / cold water header so as to be cooled by the endothermic action in the spectator seat portion. Therefore, it is possible to cover the temperature control target area by arranging the cold / hot water header in the center of the floor surface and branching the heat pipes in the entire floor surface area in a comb-like manner. Since it only needs to be performed with the flow medium, the facility load is small, and the temperature control of the predetermined area of the large space building can be performed with the economical facility.

On the floor surface 16 of the spectator seat 14 on which the cold / hot water header 18 is laid, a plurality of heat pipes 24 are further laid at intervals in the column direction with the cold / hot water header 18 as the center. The entire surface 16 is stretched. This heat pipe 24 is used for the hot and cold water header 18.
Is laid on the same plane as that of the one end, and one end side thereof is inserted into the inside of the cold / hot water header 18, and this insertion end is configured to be cooled or heated by the cold / hot water flowing in the header 18. ing. The other end side of the heat pipe 24 is laid along the floor surface 16 so as to be orthogonal to the cold / hot water header 18, and this functions as a cooling unit or a heat radiating unit.

By the way, the heat pipe 24 is shown in FIG.
As shown in (1), the evaporable liquid is sealed inside the closed tube member 26, and the wick 28 is wound around the entire inner wall surface to form a condensate flow path utilizing the capillary phenomenon, and the central passage 30 is a vapor. Functions as a flow path. Heat pipe 2
When the central portion of 4 is thermally insulated, one end thereof is heated, and the other end thereof is arranged in the low temperature region, the heating unit becomes the evaporation unit and the portion in contact with the low temperature region becomes the condensation unit. Therefore, by cooling or heating the end portion of the heat pipe 24 with the cold / hot water flowing in the header 18, it becomes possible to perform the cooling or heating operation on the other end side. In this case, if there is no heat insulating portion in the evaporation area or the condensation area, the heat pipe 24
Although one half of each of the regions becomes each region, in the embodiment shown in FIG.
As shown in (2), the end portion of the heat pipe 24 is inserted into the cold / hot water header 18, and the portion protruding from the header 18 is covered with a heat insulating cover 32 to form a heat insulating region, and a wide area of the spectator seat 12 is formed. Consideration is given to heat absorption or heat dissipation.

Further, as shown in FIG. 3, the heat pipe 2
Cold and hot water header 18 as a structure in which half of 4 is meandered and bent
Alternatively, the other half may be projected from the side wall of the header 18 as a straight pipe and laid along the floor surface 16 of the spectator seat 14. As a result, the evaporation and condensation of the internal liquid can be performed without forming a heat insulating region in the heat pipe 24. Of course, it is also possible to form a heat insulating region by covering the meandering bent portion 24A of the heat pipe 24 in the header 18 with the heat insulating film leaving only the tip end portion, and thereby improving the heat transfer efficiency.

The cooling operation by the cooling / heating device having such a configuration is as follows. The cold / hot heat source 20 described above generates cold water at 10 ° C. for the cold / hot water header 18, and the cold water is pumped by the pump 22. Cold water circulates through the header 18, and the ends of the heat pipes 24 inserted in the header 18 are cooled by the cold water. By this cooling action, the evaporative liquid in the heat pipe 24 is condensed and flows to the other end side using the wick 28 as a flow path. Since the heat pipe 24 branching and projecting from the header 18 is placed in the high-temperature air, the internal liquid evaporates, and accordingly, the internal liquid has an endothermic action to cool the ambient air. Since the heat pipe 24 is stretched all over along the floor surface 16 of the spectator seats 14 in the cooling target area, even if the theater hall 10 has a large volume, the necessary spectator seats 14 can be reliably cooled. .

On the other hand, when heating is performed, hot water of about 30 ° C. is circulated in the cold / hot water header 18 to heat the end portion of the heat pipe 24 inserted in the header 18. As a result, the internal liquid evaporates and reaches the other end through the central passage 30, where it is exposed to the ambient cold heat and condensed. The condensation heat is radiated to heat the spectator seats 14.

According to such an embodiment, since the heat pipe 24 is used, the heat transport speed is high, so that the temperature can be immediately set to the predetermined temperature. Also,
Since the temperature is controlled by the radiant heat from the heat pipe 24, a uniform temperature distribution is obtained, and the amount of exchanged heat can be freely determined, so that the device has excellent temperature controllability. Furthermore,
Since the plurality of heat pipes 24 laid in the cooling / heating target area have mutually independent structures and are not connected to each other, there is an advantage that treatment for a failure or the like becomes very easy.
