Description

{PLUME ABATEMENT COOLING TOWER}

The present invention relates to a cooling tower, and more particularly, to a white smoke reduction cooling tower.

The cooling tower serves to cool the cooling water, for example, the air conditioner or the refrigerator, that is, the cooling water used for condensing the refrigerant flowing in the refrigeration cycle by bringing it into contact with air. In order to heat-exchange the high-temperature cooling water, such a cooling tower causes the cooling water to be blown into the air or to make the flowing cooling water come into contact with the air to be blown.

In such a cooling tower, components constituting a cooling tower such as a water supply section, a blowing section, a wet heat exchange section, and a collecting section are provided inside a casing defining an outer appearance. The cooling water supplied from the water supply unit flows along the wet heat exchange unit and is heat-exchanged with air sucked into the casing by driving the air supply unit. In this way, the cooling water and the heat-exchanged air are discharged to the outside of the casing by the continuous driving of the blowing portion, and the cooling water heat-exchanged with the air is collected in the collecting portion.

Meanwhile, since the air discharged to the outside of the casing is heat-exchanged with the cooling water, the humidity is increased, so that the humid air having a relatively high temperature is discharged to the outside of the casing. Therefore, a white smoke (plume) phenomenon in which moisture in the air discharged to the outside of the casing condenses may occur.

The prior art Patent Document 1 (Korean Patent Laid-Open Publication No. 2010-0111655) discloses a cooling tower in which a heat exchanging unit 40 including an eliminator 41 and a heat line 47 is additionally provided, . In this prior art document 1, the air passing through the eliminator 41 is heated to remove moisture, thereby reducing the white smoke phenomenon.

In the prior art Patent Document 2 (Korean Patent Laid-Open Publication No. 2013-0018124), a cooling tower including an elliptical coil heating portion is disclosed. In this prior art document 2, the elliptical coil heating unit heats the cold singer water and heat exchanged air, thereby reducing the white smoke phenomenon.

However, in the case of such a conventional white smoke reduction cooling tower, the cooling water and the heat-exchanged air are heated by the heating wire 47, or the air exchanged with the cooling water flows into the space where the air heated by the elliptical coil heating unit is sucked And then discharged by the fan. Therefore, according to the related art, the moisture in the heat exchanged air and the cooling water is condensed on the surface of the hot wire 47, so that the heating performance is lowered or the hot wire 47 is damaged, or the heat exchanged air and the heated air are sufficient It is not possible to effectively reduce the occurrence of white smoke.
