What is an industrial cooling tower?
Industrial cooling towers are larger than HVAC systems and are used to remove heat absorbed in the circulating cooling water systems used in power plants, petroleum refineries, petrochemical plants, natural gas processing plants, food processing plants, and other industrial facilities.
How do industrial cooling towers work?
Cooling tower systems work by using water to extract waste heat from a system and ejecting it into the atmosphere primarily through evaporation. The water is then distributed over the top of the cooling tower where air travels past the warm water causing a portion of the water to evaporate.
Is a cooling tower an evaporator?
It contains two primary cylinders: an evaporator and a condenser. There are many different types of chillers, including centrifugal, reciprocating, screw driven, and absorption chillers. A cooling tower acts as a giant heat exchanger.
What is the difference between an evaporative condenser and a cooling tower?
A cooling tower is used to cool water by direct contact between that water and a stream of air. An evaporative condenser is used to cool water by passing that fluid through a heat exchanger which is itself cooled by contact with water passing through a stream of air.
What is the function of evaporative condenser?
An evaporative condenser is a device that converts refrigerant contained within a closed circuit from a heated vapor to a cooled liquid form by the evaporation of water sprayed on the exterior surface of the refrigerant tubing.
What are the four types of evaporators?
These evaporators are available in four configurations: rising/falling-film, falling-film, forced-circulation with suppressed boiling, and agitated thin-film. For the last type, film thinning is achieved by a combination of fluid hydrodynamics and plate geometry, rather than by a mechanical device.
Which is the most common type of evaporator?
Finned Tube
What are the two functions of the evaporator?
The evaporator works the opposite of the condenser, here refrigerant liquid is converted to gas, absorbing heat from the air in the compartment. When the liquid refrigerant reaches the evaporator its pressure has been reduced, dissipating its heat content and making it much cooler than the fan air flowing around it.
What are the two types of evaporation?
The Differences Between Vaporization & Evaporation Vaporization is the process by which a liquid is turned into a gas. The two types of vaporization are evaporation and boiling.
