Description

Hybrid Cooling Tower {HYBRID COOLING TOWER}

The present invention relates to a hybrid cooling tower.

Generally air conditioning and refrigeration. In refrigeration equipment, freezers and industrial heat exchangers carry waste heat to be removed, and waste heat must be released to the atmosphere using a cooling medium to remove this waste heat. Cooling tower's cooling method is divided into air-cooled cooling that uses convective cooling of atmospheric air which is lower than the fluid to be cooled, and evaporative cooling that uses cooling latent heat by contact of cooling water and air. It is widely used because it is more economical than other chillers and has a greater cooling effect.

Conventional cooling towers are divided into counterflow type cooling towers and cross flow type cooling towers according to the type of cooling water and air flow, and the cooling water flow is divided into open and closed cooling coils circulating through the filler. It is divided into a closed type for cooling the fluid to be cooled, and the cooling is divided into a water-cooled type that forms evaporative cooling using a cooling medium as water and an air-cooled type that cools only with air. In recent years, hybrid cooling towers combining counterflow fillers and crossflow fillers to increase the heat exchange area, and hybrid cooling towers having wet and dry heat exchangers composed of fillers and sealed cooling coils to prevent smoke, have been widely used as new technologies.

In general, a hybrid cooling tower combining a counterflow filler and a crossflow filler is provided with a counterflow filler as a first heat exchanger under the sprinkler, and a crossflow filler as a second heat exchanger is installed in a lower region of the counterflow filler. Ryu fillers are usually installed opposite each other and the central area essentially provides an airflow area for air flow and internal inspection.

Therefore, the cooling water and the air introduced through the air supply in the water spray unit is configured to heat exchange with each other through the filler.

However, in the conventional hybrid cooling tower, since the coolant heat exchanged in the counterflow filler falls directly into the air flow region in the center of the crossflow filler where the coolant exchanged with each other is disposed, there is a problem in that noise is generated by friction with the coolant stored in the sump. . In addition, in order to reduce such noise, a '∧' shaped drip plate is installed with the inner side of the cross flow filler and the bottom face of the counter flow filler as an isolation region so that the coolant does not fall on the surface of the sump tank, and the bottom of the counter flow filler Due to the direct contact between the upper surface of the crossflow filler and the upper surface of the crossflow filler without any airflow space, the flow of air from the air supply port to the counterflow filler through the crossflow filler is not only uniform but also inside the cooling tower. The resistance of the flowing air is increased, there is a problem that the operating cost is increased by the decrease in heat exchange efficiency of the cooling tower and the power of the blower fan.

In addition, the hybrid cooling tower in the form of a wet cross-flow cooling tower consisting of a cross-flow filler and an airtight cooling coil is configured to form a cross-flow filler for cooling of the cooling water sprayed on the upper layer, the middle layer, or the lower layer of the cooling coil through the water spray circulation pump. Cooling efficiency of the cooled fluid flowing through the cooling coil can be improved, but the composition and support of the crossflow filler and cooling coil are complicated in limited heat exchange area, and the fall noise is reduced unless a separate water noise reduction device is used. Difficult to do, there is a problem that can increase the cost and operating costs.

 In addition, the hybrid cooling tower of the wet and dry counterflow cooling tower type consisting of a counterflow filler used for the purpose of preventing smoke and a closed cooling coil forms an air inlet by opening one side of the upper casing of the sprinkler, and is in close contact with the air inlet. Cooling coil is installed, and the high temperature coolant circulated from the incoming air and the cooling heat exchanger makes heat exchange while flowing the cooling coil, and the hot dry air passing through the cooling coil forms heat exchange through the counterflow filler and blows the fan. Moisture is mixed with the humid air flowing toward to reduce moisture, and the cooling water passing through the cooling coil is subsequently sprayed into the counterflow filler through the cooling water inlet pipe and the spray nozzle. Therefore, although there is an effect of reducing white smoke from the air discharged during the operation of the cooling tower at a low temperature of the ambient air temperature, the air mixing device and the cooling that properly mixes the high temperature dry air flowing from the cooling coil and the high temperature wet air flowing from the counter-flow filler Due to the laying of the structure according to the exterior of the coil, the structure is complicated, the cost is also greatly increased, there is a problem that can not reduce the fall noise unless a separate drop noise reduction device.

Accordingly, an object of the present invention is to provide a hybrid cooling tower that can reduce noise caused by falling water of the cooling water, improve heat exchange efficiency of the cooling tower, and reduce operating costs.

Another object of the present invention is to form a heat transfer tube of a cooling fluid, such as a condenser for condensing a refrigerant that can be operated wet and dry in a cooling tower, and an absorber for cooling and absorbing an absorbing solution in the cooling tower, thereby improving cooling efficiency and reducing cost and operation.

The pair of crossflow fillers 23 are provided adjacent to the air supply ports 13 at predetermined intervals. Accordingly, the coolant passing through the counterflow filler 21 and the air introduced from the air supply port 13 are evaporated and heat exchanged while crossing each other in the crossflow filler 23, so that the coolant is cooled. Here, in order to reduce the fall noise of the coolant which goes to the sump tank 53 through the crossflow filler 23, it is preferable that the bottom area | region of the crossflow filler 23 is immersed in the sump tank 53.
