[0003]

A pond or waterfall as a scenic facility is conventionally used only for scenic purposes, that is, merely for the purpose of showing, and has not been effectively used for other purposes. An object of the present invention is to measure the effective use of a scenic facility.

[0004]

According to the present invention, in order to solve the above-mentioned problems, a pond and a waterfall falling on the pond are constructed as a scenic facility, and a heat exchange pipe is installed in the pond and the waterfall. Exhaust air that has passed through the heat exchange pipe in the pond and waterfall is blown out from the back of the waterfall toward the water that falls as a waterfall, while the surplus cooling air from the air conditioning system is made to flow into the heat exchange pipe. We propose an air-conditioning cooling auxiliary device that constitutes a water circulation system for using the water of the air as cooling water for air-conditioning.

According to the present invention, in the above construction, an upper water storage section is formed above the pond, a cylindrical overflow section is arranged in the upper water storage section, and a plurality of heat exchange pipes are erected from the pond. It is proposed that a waterfall is formed by coaxially penetrating the overflow part and water overflowing from the cylindrical overflow part falls along the heat exchange pipe.

In the present invention, it is proposed that the general exhaust of the building is jetted from the back side toward the water falling as a waterfall.

According to the present invention, surplus cooling heat is recovered in the water of the pond and the waterfall by flowing the surplus cooling air exhaust from the air conditioning system of the building to the heat exchange pipe installed in the pond and the waterfall to exchange heat with the water. This can be effectively used as cooling water for air conditioning via an appropriate water circulation system.

FIG. 1 is a block diagram showing an embodiment of the present invention.
This will be described with reference to FIG. FIG. 1 is a partially sectional perspective view of a pond and a waterfall as a scenic facility to which the present invention is applied, viewed from the back side, and FIG. 2 is a sectional view including a water and exhaust system. In the drawing, reference numeral 1 denotes a wall of a building, and a pond 2 for a landscape is formed in front of the wall 1. Above pond 2,
The upper water storage section 3 is configured.
A cylindrical overflow section 4 composed of a cylindrical body standing upward from the bottom wall.
Are arranged in parallel with the wall 1 so that the water overflows from the cylindrical overflow portion 4 to form a waterfall. The form of arrangement of the plurality of cylindrical overflow portions 4, that is, the planar shape of the waterfall, is not only linearly arranged in parallel with the wall 1 as in this embodiment, but also arranged so as to be inclined with respect to the wall 1. They can be arranged or arranged in a curved line.

Reference numeral 5 denotes a first heat exchange pipe installed in the pond 2 in a lateral direction, and a plurality of second heat exchange pipes 6 are provided upright on the first heat exchange pipe. An upstream side of the first heat exchange pipe 5 is connected to a cooling excess exhaust system 7 of an air conditioning system (not shown), and the first heat exchange pipe 5 includes a plurality of second heat exchange pipes 6. It also acts as a header to allow excess cooling air to flow.

[0010] A plurality of second heat exchange pipes 6 penetrate coaxially with the respective cylindrical overflow portions 4, and as shown in the figure,
A gap is formed between the second heat exchange pipe 6 and the cylindrical overflow section 4, and the water overflowing from the cylindrical overflow section 4 of the upper water storage section 3 falls along each of the second heat exchange pipes 6. In this way, thus constituting a waterfall for scenic views. Since this waterfall falls along the second heat exchange pipe 6, it does not scatter and does not wet a person in front of the waterfall. The amount of water falling as a waterfall and the falling speed can be adjusted by the gap between the second heat exchange pipe 6 and the cylindrical overflow section 4. Since the second heat exchange pipe 6 is made of a transparent material, the appearance can be improved, and a lighting fixture is installed at an appropriate place such as a lower portion of the second heat exchange pipe 6 to further improve the appearance. Can be done.

The upper part of the second heat exchange pipe 6 penetrating the cylindrical overflow part 4 is connected to an exhaust duct 8 via a header, and the end of the exhaust duct 8 has a structure such as a gusset installed on the wall 1. It is connected to an appropriate number of first exhaust ports 9 and is configured to eject exhaust gas from the exhaust ports 9 toward water falling as a waterfall.

On the other hand, an appropriate number of second exhaust ports 10 are installed on the wall 1, and this second exhaust port 10 is connected to a general exhaust system in a building, and general exhaust is also performed in the same manner as described above. It is configured to squirt from the exhaust port 10 toward water that falls as a waterfall.

On the other hand, a water circulation system 12 having a pump 11 for sending water in the pond 2 to the upper water storage unit 3 is formed. The water circulation system 12 includes a cooling water system (not shown) of an air conditioner. A heat exchange unit 13 for exchanging heat is configured.
In this embodiment, the heat exchange unit 1 is connected to the water circulation system 12.
3, the heat exchange unit 13 may be configured as a circulation system configured separately from the water circulation system 12.

In the above configuration, the water in the pond 2 is supplied to the upper reservoir 3 through the water circulation system 12 by the pump 11. The water in the upper water storage section 3 overflows from the cylindrical overflow section 4,
The water falls along the second heat exchange pipe 6 into the pond 2 as a waterfall. At this time, in the cooling operation in the building during the cooling period, if excess cooling exhaust is lower than the outside air temperature, and the excess cooling exhaust is passed through the excess cooling exhaust system 7, the excess cooling exhaust is converted to the first excess cooling air. After flowing from the heat exchange pipe 5 to the second heat exchange pipe 6 and exchanging heat with water in these pipes 5 and 6 to cool the water, it is ejected from the exhaust port 9 on the back side of the waterfall through the exhaust duct 8. Exchanging heat in direct contact with the water of the falls. Therefore, the water of the waterfall is cooled by the sensible heat of the cooling excess exhaust gas and the heat of vaporization of the water itself.

In this embodiment, since the general exhaust gas in the building blows out from the exhaust port 10 toward the water of the waterfall, the water of the waterfall is generated by the sensible heat of the general exhaust gas and the heat of vaporization of the water itself. Is also cooled.

Thus, according to the present invention, the cooling heat of the cooling excess exhaust can be recovered into the water of the pond (and the waterfall), and the circulating water can be cooled by utilizing the heat of vaporization by the exhaust. The cooled circulating water can be effectively used as the cooling water for the air conditioner by operating the heat exchange unit 13 as necessary and exchanging heat with the cooling water system (not shown) of the air conditioner. .

As described above, the present invention has the following effects. a. The present invention is based on the premise that ponds and waterfalls for scenic views are installed, but the scenic facilities that were conventionally installed simply for the purpose of showing are actively used for cooling assistance for air conditioning. By recovering the cooling heat of the cooling excess exhaust and effectively using it for air conditioning, it is possible to save energy and reduce the cooling tower capacity of the air conditioning equipment. b. Since the building exhaust fan can be used without specially installing a fan used in a normal cooling tower, the initial and running costs are reduced even if the static pressure of the exhaust fan is slightly increased. be able to. c. The waterfall of the waterfall can be appropriately adjusted in consideration of the beauty of the waterfall and the heat exchange performance between the exhaust and water in the heat exchange pipe. d. Exhaust outlets such as gulls can be installed behind the waterfall, eliminating the need to install them on the exterior wall of the building as seen from the outside, which contributes to improving the appearance of the building.
