1 is a longitudinal cross-sectional view showing a first embodiment of a cooling tower according to the present invention, Figure 2 is a cross-sectional view showing a first embodiment of the present invention.

1 and 2, in the present embodiment, the inner wall 10 and the slab 30 define a predetermined space provided in the building B, that is, the underground space 40. For example, the inner wall 10 may be formed in a polyhedron shape having a predetermined cross section. And substantially, by stacking a plurality of the slab 30 is spaced up and down, the underground space 40 may be composed of a plurality of layers. The underground space 40 defined by the inner wall 10 and the slab 30 may be used, for example, as an underground parking lot.

Meanwhile, the outer wall 20 is positioned to surround the inner wall 10. The outer wall 20 may be located at the outer side of, for example, facing surfaces of the inner wall 10. As the slab 30 extends to the outer wall 20, a predetermined space partitioned from the underground space 40 by the inner wall 10, the outer wall 20, and the slab 30 may be defined. . In this manner, the predetermined space defined by the inner wall 10, the outer wall 20, and the slab 30 forms the intake flow path 50 and the exhaust flow path 60. Communication slabs 31 are formed in the slab 30. The communication opening 31 is formed by cutting a part of the slab 30 corresponding to the inner wall 10 and the outer wall 20. Therefore, the intake flow path 50 and the exhaust flow path 60 corresponding to each layer may be communicated up and down substantially by the communication opening 31. In the intake passage 50 and the exhaust passage 60 spaced apart from the communication opening 31 in the horizontal direction, air flows in a horizontal direction, and on the communication opening 31 in the vertical direction. There will be a flow of air.

On the other hand, the inlet port 51 and the exhaust port 61 are provided in the upper end of the intake flow path 50 and the exhaust flow path 60, respectively. The intake port 51 and the exhaust port 61 communicate with the ground, respectively, and serve as an inlet through which air flowing through the intake flow path 50 is supplied, or an outlet through which air flowing through the exhaust flow path 60 is discharged. do.

In addition, a ventilation duct 70 is provided in the basement space 40. For example, the ventilation duct 70 may be located at an upper surface of the underground space 40 so that both ends thereof communicate with the intake passage 50 and the exhaust passage 60. In addition, at least one ventilation opening 71 may be formed in the ventilation duct 70 for ventilation of the underground space 40.

On the other hand, a cooling tower is provided on the exhaust passage 60. The cooling tower serves to heat exchange the cooling water used for condensation of the refrigerant in the air conditioning apparatus for air conditioning of the building, that is, cool the cooling water. Such a cooling tower includes a heat exchanger 100, a cooling water circulation device 200, and a blower device 300. Substantially, the cooling tower may be called a cooling system since it performs heat exchange of cooling water.

In more detail, the heat exchange apparatus 100 is provided on the upper surface of the slab 30 corresponding to the exhaust passage 60. At this time, the heat exchange apparatus 100 is located upstream of the communication opening 31 in the direction in which air flows through the exhaust passage 60. For example, the heat exchange device 100 may be located adjacent to both sides of the communication opening 31 or to one side of the communication opening 31. In FIG. 1, the heat exchanger 100 includes the heat exchanger 100 on an upper surface of all the slabs 30 except for one of the slabs 30 corresponding to the lowermost layer of the slabs 30 defining each layer. Are each provided. However, the heat exchange device 100 may be provided only on an upper surface of a part of the slab 30.

The heat exchange apparatus 100 includes a plurality of fillers 110. The filler 110 may be disposed, for example, in a direction parallel to a direction in which air flows through the exhaust flow path 60. The filler 110 may be spaced apart from each other in a direction orthogonal to a direction in which air flows through the exhaust flow path 60. The coolant flowing substantially along one or both surfaces of the filler 110 is cooled in contact with the air flowing through the exhaust passage 60.

The cooling water circulation device 200 serves to circulate the cooling water to be cooled while flowing along the filler 110. The cooling water circulation device 200 includes a water supply pipe 210, a nozzle 220, a water collecting member 230, a recovery pipe 240, a water tank 250, and a pumping member (not shown).

In more detail, the water supply pipe 210 serves to supply cooling water to the filler 110, respectively. The nozzle 220 serves to spray the cooling water supplied by the feed pipe 210 toward the filler 110. For example, the nozzle 220 may be located above the filler 110. Cooling water that is sprayed by the nozzle 220 and flows along the filler 110 is collected in the collecting member 230. To this end, the collecting member 230 may be located below the filler 110, that is, the upper surface of the slab 30. In addition, the recovery pipe 240 serves to recover the cooling water collected in the collecting member 230. To this end, the recovery pipe 240 connects the water collecting member 230 and the water tank 250. The water tank 250 is a place where the coolant collected by the recovery pipe 240 is collected. In other words, the water tank 250 is a place where all the coolant collected in the water collecting member 230 is stored. In the present embodiment, the water tank 250 is positioned below the heat exchanging device 100 as compared with any one of the heat exchanging devices 100 located at the relatively lowermost position. In other words, the water tank 250 may be at least positioned below the water collecting member 230. The pumping member provides a driving force for supplying the cooling water to the filler 110 and for recovering the cooling water flowing through the filler 110. For example, the coolant is supplied to the filler 110 by the pumping member, and the coolant flowing through the filler 110 and collected in the collecting member 230 is stored in the water tank 250 by gravity. Can be.

The blower device 300 forms a flow of air for ventilation of the underground space 40 and heat exchange of cooling water flowing along the filler 110. For example, the blower device 300 may be installed adjacent to the intake port 51. However, the position of the blower 300 will not be limited thereto.

The blowing device 300 may include substantially one or a plurality of blowing fans. In addition, the blower 300 may be selectively operated or the number of rotations may be adjusted depending on whether air conditioning or ventilation is performed on the building B. FIG. For example, when both the air conditioning and the ventilation for the building (B) is performed, all of the blower device 300 is operated, or the rotation speed of the blower device 300 may be increased. When only one of the air conditioning and the ventilation for the building B is performed, only a part of the blower 300 may operate or the rotation speed of the blower 300 may be reduced. In addition, when both the air conditioning and the ventilation for the building (B) is not performed, the blowing device 300 may be stopped.

Hereinafter, the operation of the first embodiment of the cooling tower according to the present invention will be described in more detail.

First, when the blower 300 operates, outdoor air is sucked through the inlet port 51 and flows through the intake flow path 50. The air flowing through the intake flow passage 50 flows through the ventilation duct 70 while ventilating the underground space 40. And the air which flowed through the said ventilation duct 70 flows out through the exhaust flow path 60, and is discharged | emitted outside through the exhaust port 61.

On the other hand, if the air conditioning for the building (B) is performed, it is necessary to cool the cooling water used for the condensation of the refrigerant. To this end, when the coolant circulation device 200 operates, heat exchange of the coolant is performed in the heat exchange device 100, that is, the coolant is cooled.

More specifically, when the pumping member is operated, the coolant stored in the water tank 250 flows through the feed water pipe 210, and then is sprayed by the nozzle 220. Therefore, the coolant flows along the filler 110. By the way, the filler 110 is substantially located on the exhaust flow path (60). Therefore, the coolant flowing along the filler 110 may be in contact with the air flowing through the exhaust flow path 60, and thus may be cooled.

Next, the coolant that is heat-exchanged with air while flowing the filler 110 is collected inside the collecting member 230. The coolant collected in the water collecting member 230 is collected by the water tank 250 after flowing the recovery pipe 240 by its own weight.

Therefore, in the present exemplary embodiment, the ventilation device 300 and the heat exchange of the cooling water of the underground space 40 may be performed by the same blower device 300. Therefore, compared with the related art, the cost required for the ventilation of the underground space 40 and the heat exchange of the cooling water can be reduced.

Hereinafter, with reference to the accompanying drawings a second embodiment of the cooling tower according to the present invention will be described in more detail.

3 is a cross-sectional view showing a second embodiment of the cooling tower according to the present invention. The same reference numerals in Figs. 1 and 2 are used for the same components as those in the first embodiment of the present invention described above, and detailed description thereof will be omitted.

Referring to FIG. 3, in the present embodiment, a heat exchange space 80 and a bypass space 90 are provided on the upper surface of the slab 30 corresponding to the exhaust flow path 60. The heat exchange space 80 and the bypass space 90 are located upstream of the communication opening 31 in the direction in which air flows through the exhaust flow path 60, respectively. For example, the heat exchange space 80 and the bypass space 90 may be located adjacent to both sides of the communication opening 31, respectively. The heat exchange space 80 and the bypass space 90 may be located on an upper surface of some or all of the slab 30.

More specifically, the heat exchange space 80 and the bypass space 90 may be defined by a separate member, for example, a wall, on the upper surface of the slab 30. In this case, the heat exchange space 80 and the bypass space 90 may be formed to be partitioned from the exhaust passage 60 by the wall. At least a part of the heat exchange space 80 and the bypass space 90 are located at the same flow side in the direction in which air flows through the exhaust flow path 60. For example, the heat exchange space 80 and the bypass space 90 may be partitioned in a horizontal direction perpendicular to a direction in which air flows through the exhaust flow path 60. In FIG. 3, the cross sectional area of the bypass space 90 is shown to be relatively small compared to the heat exchange space 80. However, the flow cross sectional area of the heat exchange space 80 and the bypass space 90 may be the same, or the flow cross sectional area of the bypass space 90 may be relatively larger than the flow cross sectional area of the heat exchange space 80. to be. In addition, the heat exchange space 80 and the bypass space 90 may be divided up and down.

The heat exchange space 80 and the bypass space 90 are provided with a first suction opening 81, a first discharge opening 83, a second suction opening 91, and a second discharge opening 93, respectively. . The first and second suction openings 81 and 91 are provided on one surface of the heat exchange space 80 and the bypass space 90 corresponding to an upstream side in the direction in which air flows through the exhaust flow path 60. Is formed. The first and second discharge openings 83 and 93 are different from the heat exchange space 80 and the bypass space 90 corresponding to the downstream side in the direction in which air flows through the exhaust flow path 60. It is formed on one side. Therefore, the air flowing through the exhaust flow path 60 is sucked through the first and second suction openings 81 and 91 to flow inside the heat exchange space 80 or the bypass space 90. Thereafter, it is discharged to the outside of the heat exchange space 80 or the bypass space 90 through the first and second discharge openings 83 and 93.

First and second dampers 85 and 95 are disposed on the first and second suction openings 81 and 91. The first and second dampers 85 and 95 may be rotatably installed on a wall defining the heat exchange space 80 and the bypass space 90. The first and second dampers 85 and 95 open or close the first and second suction openings 81 and 91 according to whether or not heat exchange of cooling water is necessary or the amount of ventilation of the underground space 40. The degree of opening of the first and second suction openings 81 and 91 is adjusted.

In addition, in this embodiment, the circulation of the cooling water, that is, the operation of the cooling water circulation device 200 (see FIG. 1) may be performed according to whether the first damper 85 is opened or closed. Substantially, the pumping member (not shown) may operate only when the first damper 85 is opened.

Hereinafter, the operation of the second embodiment of the cooling tower according to the present invention will be described in more detail with reference to the accompanying drawings.

4 and 5 are operation state diagrams showing the heat exchange operation of the cooling water in the second embodiment of the cooling tower according to the present invention.

First, referring to FIG. 4, when air conditioning of the building B is performed, that is, when the heat exchange of the cooling water, that is, the cooling water is required, the first damper 85 opens the first suction opening 81. do. Therefore, when the blower device 300 (see FIG. 1) operates, air is sucked into the heat exchange space 80 through the first suction opening 81, and then flows through the inside of the heat exchange space 80. It is discharged through the first discharge opening 83. The air discharged through the first discharge opening 83 flows through the exhaust flow path 60, and then is discharged to the outside through the exhaust port 61 (see FIG. 1).

Meanwhile, when the pumping member operates, the coolant stored in the water tank 250 flows through the water supply pipe 210, and then is sprayed by the nozzle 220. Accordingly, while the coolant flows along the filler 110, the coolant may be cooled by air flowing in the heat exchange space 80.

Substantially, supply and circulation of cooling water can be said to be the same as that of the first embodiment of the present invention described above. However, as described above, in the present embodiment, the pumping member, that is, the coolant circulation device operates only in a state where the first suction opening 81 is opened by the first damper 85.

Of course, the second suction opening 91 may be opened and closed by the second damper 95 according to the required ventilation amount of the underground space 40. That is, when the required ventilation amount for the underground space 40 is large, the second damper 95 may open all or part of the second suction opening 91.

Next, referring to FIG. 5, when ventilation for the underground space 40 is required and air conditioning of the building B is not performed, the first damper 85 opens the first suction opening 81. Shielding, the second damper 95 opens the second suction opening (91). Accordingly, when the blower 300 operates, air is sucked into the bypass space 90 through the second suction opening 91, but suction of air is prevented from the heat exchange space 80. The air sucked into the bypass space 90 is discharged through the second discharge opening 93 after flowing through the bypass space 90. In addition, the air discharged to the outside of the bypass space 90 through the second discharge opening 93 flows through the exhaust passage 60, and then is discharged to the outside through the exhaust port 61.

In other words, when air conditioning for the building B is not performed, that is, when no heat exchange of cooling water is required, the air flowing through the exhaust flow path 60 passes only through the bypass space 90. The heat exchange space 80 is not via. Therefore, it is possible to prevent the phenomenon in which the heat exchanger 100, in particular the filler 110, is unnecessarily contaminated by contaminants included in the air that substantially ventilates the underground space 40.

When the air conditioning for the building B and the ventilation for the underground space 40 are not performed, the first and second suction openings may be opened by the first and second dampers 85 and 95. 81 and 91 are respectively shielded. In addition, since the blower 300 is also stopped, the flow of air in the exhaust passage 60 is not generated.

Hereinafter, with reference to the accompanying drawings a third embodiment of the cooling tower according to the present invention will be described in more detail.

6 is a cross-sectional view showing a third embodiment of the cooling tower according to the present invention. For the same components as those of the first embodiment of the present invention described above among the components of the present embodiment, reference numerals of FIGS. 1 to 3 are used, and detailed description thereof will be omitted.

Referring to FIG. 6, in this embodiment, the auxiliary blower 400 is provided on the exhaust flow path 60. The auxiliary blower 400, like the blower 300, forms a flow of air for heat exchange of the coolant in the heat exchanger 100 and the filler 110. The auxiliary blowing device 400 may be installed on the exhaust flow path 60 corresponding to an upstream side of the heat exchange device 100 in a direction in which air flows through the exhaust flow path 60. . Of course, according to the position of the heat exchange device 100, the auxiliary blower 400 may be located downstream of the heat exchange device 100 in the direction in which air flows through the exhaust flow path (60) Of course.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents. .
