Dry cooling tower - cooling of liquids by coolers

Without technical water, it is impossible to work in a variety of spheres. Up-to-date information on how this liquid is cooled.

Cooling of liquids with coolers

Thermal and nuclear power plants, as well as industrial enterprises, use a lot of technical water every day, which is used to cool various mechanisms and units. The water becomes much warmer. And since in the cooling process it moves in a circle in a closed loop, it becomes necessary to cool it. At large facilities such as power plants, where large volumes of water have to be cooled, tower cooling towers are used.

In small industrial plants, the volume of cooled water is much lower. In this case, a dry cooling tower acts as a heat exchanger in refrigerating equipment , which is also called a dicculer.

The main function of this device is partial cooling of liquids. A dry cooler does not make the water icy, but only lowers its temperature. For example, if the water entering the cooling tower is 50 degrees Celsius, then it will be about 30 degrees at the outlet.

Dry cooler

The drayculor is a ribbed tube heat exchanger that is equipped with fans to cool the coolant circulating in a closed loop. Thus, the cooling of water in this device is effected by the action of the air flow, which is pumped by the "turntable".

Dry cooling tower is designed for outdoor installation, the coolant in it uses water with glycol, which protects the device from freezing. From the liquid cooler is supplied to the refrigeration system for cooling mechanisms and assemblies. Then it returns to the cooling tower, where heat is discharged into the atmosphere.

Typically, the dry cooler is equipped with axial fans, the power of which is quite sufficient to create the necessary force of the forced air flow. If it is necessary to increase the head, the driver is equipped with more powerful centrifugal fans.

The cooling tower is used not only in industry, it was used in large stores / supermarkets, where it (together with chillers) is used in air conditioning systems. In such cases, compressor installations are usually installed in special technical rooms with good sound insulation, and cooling towers are placed on the roof of the building or a site equipped for this purpose.

Advantages of dry cooler

Using a drive cooler has some advantages. The most important thing is that when it is used there is no evaporation of the coolant, as it circulates in a closed closed loop. Therefore, the device is called a dry cooling tower.

The coolant in such cooler is not contaminated and does not need additional cleaning after cooling. Addition of glycol in water protects the entire circuit from defrosting.

The use of a dry coolant can not lead to chemical contamination of the environment and does not increase the humidity of the air. This explains why the dry cooling tower is used in those places where the environmental situation is given increased attention.
