how does a cooling tower work youtube
The primary function of a cooling tower is to chill down water that has been heated up by manufacturing equipment and methods. This is known as evaporative cooling.

This video explains how cooling towers work and the working principle behind all wet type cooling towers.
. A cooling tower is a heat removal device that uses water to transfer process waste heat into the atmosphere. In this video we look at how a cooling tower works. Cooling towers work by using air to cool a working fluid water.
This is an ideal video for HVAC Power Plant Engine. The air flows in the opposite direction to the flow of condenser water. A cooling tower is a large heat exchanger unit which provides cooling water to remove heat from a coolant most often water that has been used to cool machinery process fluids or buildings.
Open cooling towers work by using evaporated water to remove process heat and cool the working fluid at or near the wet-bulb air temperature. Evaporative cooling towers or cooling towers are devices which make use of a natural principle which is as simple as it is effective. The fan pulls air through the filters at the bottom of the unit and move it up and out through the top of the cooling tower passing through the fill packaging and drift eliminators.
Cooling towers are a special type of heat exchanger that allows water and air to come in contact with each other to lower the temperature of the hot water. The main difference is that cooling fluids are kept in a closed circuit that does not directly come into. The system creates a unique kind of heat exchange that lowers the temperature of hot water when air and water come into contact with one another.
Learn about the workings of the Hope Creek cooling tower. For greater cooling capacity cooling towers use a fan to create more evaporation. A cooling tower is responsible for cooling down water after it becomes overheated by industrial equipment and processes.
This produces low entering and high exiting air velocities reducing the possibility of recirculation in which discharged air flows back into the air intakeThis fanfill arrangement is. All cooling towers including commercial industrial cooling towers operate on the principle of removing heat from water by evaporating a small portion of water that is recirculated through the unit. There are primarily three different methods in which a cooling tower can remove heat from water.
An Induced draft cooling tower is a mechanical draft tower with a fan at the discharge to pull air through it. The mass therefore cools down latent heat of evaporation. This material is what fills the inside of the cooling tower and is called Cooling Tower Fill.
Cooling towers are designed to increase the surface area of this heat transfer process and therefore increasing the efficiency of the rejection of heat from the system through evaporation. Large fans are placed towards the top of the cooling tower just below the pipes which bring the boiling hot water into the tower. During the cooling tower working process small volumes of water evaporate lowering the temperature of the water thats being circulated throughout the cooling tower.
The fan induces hot moist air out the discharge. The water is then sprayed through the hollow core of the cooling tower onto a grid in the center of the tower. During this process small volumes of water evaporate lowering the temperature of the water.
The cooling process that takes place within the towers is based on the principle of thermodynamics where heat will flow from hot to cold. The basic operation is. Evaporation removes heat from the water cooling it.
Cool air flows up from the hollow center and passes the warm falling water causing some of it to evaporate. During the process small amounts of water evaporate work to lower the. Cooling towers are essentially large boxes designed to maximize evaporation of water.
To do this they contain material typically PVC plastic sheets that create large surface areas for water evaporation to occur. Cooling towers are a special type of heat exchanger that allows water and air to come in contact with each other to lower the temperature of the hot water. Closed circuit dry cooling towers use air to cool working fluid to near dry-bulb air temperature.

This not only cools the water as it flows through the pipes prior to hitting the water distribution system but also helps to push steam up through the top of the tower. The forced evaporation of a minimum quantity of water compared to the main mass takes place by the dissipation of heat from the mass itself.
Water which enters inside the cooling tower will be hot because of the automated process and exit out of it as cold chilled water to add up again into the programmed process. We take an overview of each main component with real world examples colour illustrations and 3D models t. When the cooling water meets with air a small portion evaporates lowering its temperature.
Direct Cooling Open Loop This is done by bringing the water into direct contact with air.
