Description of the Related Art Recently, due to the widespread use of air-conditioning equipment, comfort has been maintained in the indoor space of large-scale customer facilities such as dome stadiums and aquariums, but on the other hand, the heat island phenomenon has progressed especially in large cities. There is a large disparity between the comfort of the indoor space and the access areas such as promenades and overpasses that lead to the facility for attracting customers, and the discomfort when going in and out of the facility through the access is remarkable in the summer. large. In summer, the quality of comfort when passing through the access section has a great influence on the customer attraction rate at the customer attraction facility.

Promenades and overpasses are often used in the access sections to the facility for attracting customers, but conventionally, no attempt has been made to actively cool these access sections.

[0004]

SUMMARY OF THE INVENTION The present invention has been made under the above circumstances, and particularly in the summer, the access part leading to the customer attraction facility is actively cooled to maintain the comfort of the passerby and to provide the customer attraction facility. It is an object of the present invention to provide a cooling device for an access part to a customer attraction facility that can reduce the difference between the comfort of the indoor space and the comfort of the indoor space.

[0005]

A cooling device for an access portion to a customer attraction facility according to the present invention is provided with a nozzle for spraying water in a mist form at an access portion such as a promenade or an overpass leading to the customer attraction facility. Is.

[0006]

According to this structure, since the water is sprayed from the nozzle in the form of mist, the amount of water used is extremely small, and the sprayed mist stays in the access part and takes heat from the surroundings to lower the dry-bulb temperature. . Further, since the water spray is performed in the form of mist, the mist does not substantially wet the pedestrians and the road surface and produces cold air.

[Embodiment] FIG. 1 is a schematic explanatory view of an embodiment in which the present invention is applied to an overpass type promenade that connects a city center such as a downtown area or a resort area with a large-scale customer attraction facility such as a dome stadium or an aquarium. Yes, 1 is a facility for attracting customers, and 2 is a promenade as an access unit. A plurality of nozzles 4, ... Are arranged at predetermined positions along the passageway surface 3 of the promenade 2 in the vicinity thereof. The nozzle 4 is a water spraying nozzle and has a function of spraying extremely fine water particles of 50 μm or less, preferably 20 μm or less, in a wide range. A water supply pipe 5 is connected to the plurality of nozzles 4 ... And a control valve 6 is interposed in the water supply pipe 5. Reference numeral 7 denotes a water supply pump. For this water supply pump 7, for example, an underwater pump installed in a water supply source (not shown) such as a water storage tank is used. By operating this water supply pump 7, the water supply source water Is supplied to the nozzles 4 through the water supply pipe 5.

According to the above construction, when the temperature of the promenade 2 becomes high and the passerby feels uncomfortable in the summer, for example, the control valve 6 is opened and the water pump 7 is used.
When water is supplied from the water supply source to the nozzles 4 through the water supply pipe 5 by the operation of No. 4, the passage 4 and the arcade 8 from the nozzles 4 ...
A mist of water is sprayed into the space of the promenade 2 surrounded by. Due to such water spray, a mist composed of extremely fine water particles of 50 μm or less stays in the space of the promenade 2, and cold air is generated by the mist to enhance the comfort of passersby. In this case, even if the surface of the road surface 3 is wet by the fog, the water particles of the fog are extremely fine particles of 50 μm or less, so it is judged visually that the surface of the road surface 3 is wet. It cannot be or is only moist at a level that is difficult to judge, and does not get wet enough to cause water to flow. Therefore, not only does the passerby not worry about splashing or slipping muddy water, but the water that wets the road surface 3 is deprived of heat from the road surface 3 and efficiently evaporated, and the cooling action of the evaporation causes the cooling of the road surface 3 to occur. As the temperature is lowered, the temperature near the road surface 3 is also lowered.
Efficient cooling is achieved. Even if fog adheres to passersby,
As described above, the water particles of the mist are extremely fine particles of 50 μm or less, and therefore passers-by are hardly wet.

FIG. 2 shows an example in which vegetation 9 is arranged on the above-mentioned promenade 2 so as to retain fog. If the vegetation 9 is provided in the area where the fog stays in this way, the fog adheres to the vegetation 9 and retains the water for a relatively long time. Therefore, it is possible to cool the plant as if it was sowed. The feeling is exerted and the comfort of passersby is further enhanced. The same effect can be achieved by providing the promenade 2 with a member such as a louver that has a function of retaining fog instead of the vegetation or instead of the vegetation.

FIG. 3 shows an example in which a monument 11, vegetation 9 and a bench 12 are provided in an access portion outside the entrance / exit 10 of the customer attraction facility 1, so that the area around the monument 11 can be used as a waiting place. And monument 1
Nozzles 4 are arranged at appropriate positions of 1 and at appropriate positions of the entrance and exit 10, and water is sprayed from these nozzles 4 in a mist state. With this arrangement, the access portion used as a waiting place is cooled by the sprayed mist, and at the same time, the vegetation 9 exerts the function of retaining the mist. In addition, fog accumulated around the monument 11
If the movement is added by hiding or displaying a part of the monument, the monument 11 attracts the attention of a passerby or the like, and the so-called eye catching action is enhanced.

FIG. 4 shows an example in which the present invention is applied to an access section in which a display board 15 such as an advertisement or a signboard is installed.
In this case, the nozzles 4 are arranged around the surface of the display plate 15 or at a predetermined position in the display plate 15 so that the fog sprayed from the nozzles 4 can stay along the front surface of the display plate 15. It has become. With this arrangement, the mist sprayed from the nozzles 4 causes the display plate 15 to move, so that the display plate 15 attracts the attention of passersby and the so-called eye catching action is enhanced. In addition, since the display plate 15 itself and its surroundings are cooled by the fog, it is possible to prevent a situation in which a person does not approach due to a high temperature near the display plate 15. If the vegetation 9 is provided under the display plate 15, the fog retaining function is enhanced by the vegetation.

The present invention can also be applied to an access section constituted by an overpass.

[0013]

According to the cooling device for the access part to the facility for attracting customers according to the present invention, cold air can be generated in the access part, and the comfort of the passerby can be maintained at the access part.
The difference with the comfort of the indoor space of the customer attraction facility is reduced, which helps to increase the customer attraction rate of the customer attraction facility. Further, since a wide range can be cooled with a small amount of water, it is excellent in economic efficiency.
