Cooling Tower

A hyperboloid cooling tower was patented by the Dutch engineers Frederik van Iterson and Gerard Kuypers in the Netherlands on August 16, 1916.[10] The first hyperboloid reinforced concrete cooling towers were built by the Dutch State Mine (DSM) Emma in 1918 in Heerlen.[11] The first ones in the United Kingdom were built in 1924 at […]

Cooling towers originated in the 19th century through the development of condensers for use with the steam engine.[5] Condensers use relatively cool water, via various means, to condense the steam coming out of the cylinders or turbines. This reduces the back pressure, which in turn reduces the steam consumption, and thus the fuel consumption,...

A cooling tower is a device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream, to a lower temperature.[1] Cooling towers may either use the evaporation of water to remove heat and cool the working fluid to near the wet-bulb air temperature or, in the case […]

Crossflow is a design in which the airflow is directed perpendicular to the water flow (see diagram at left). Airflow enters one or more vertical faces of the cooling tower to meet the fill material. Water flows (perpendicular to the air) through the fill by gravity. The air continues through the fill and thus past […]

On 16 August 1916,[22] Frederik van Iterson took out the UK patent (108,863) for Improved Construction of Cooling Towers of Reinforced Concrete.[23] The patent was filed on 9 August 1917, and published on 11 April 1918. In 1918, DSM built the first hyperboloid natural-draft cooling tower at the Staatsmijn Emma, to his design. Hyperboloid (sometimes...

In a wet cooling tower (or open circuit cooling tower), the warm water can be cooled to a temperature lower than the ambient air dry-bulb temperature, if the air is relatively dry (see dew point and psychrometrics). As ambient air is drawn past a flow of water, a small portion of the water evaporates, and […]

Wet cooling towers or open-circuit Cooling Tower or evaporative cooling towers operate on the principle of evaporative cooling. The working coolant (usually water) is the evaporated fluid, and is exposed to the elements. Closed circuit cooling towers (also called fluid coolers) pass the working coolant through a large heat exchanger, usually a...

Industrial cooling towers Industrial cooling towers for a power plant Industrial cooling towers for fruit processing Industrial cooling towers can be used to remove heat from various sources such as machinery or heated process material. The primary use of large, industrial cooling towers is to remove the heat absorbed in the circulating cooling...

An HVAC (heating, ventilating, and air conditioning) cooling tower is used to dispose of (“reject”) unwanted heat from a chiller. Liquid-cooled chillers are normally more energy efficient than air-cooled chillers due to heat rejection to tower water at or near wet-bulb temperatures. Air-cooled chillers must reject heat at the higher...

A heat exchanger, typically with fins or tubes, is used to transfer heat from the fluid being cooled to the circulating air.       Air is drawn across the heat exchanger by fans, absorbing the heat.       The heated air is then expelled into the environment. Advantages:...

Dry cooling systems do not involve water evaporation, leading to significant water savings. •             Closed-Loop System: The fluid being cooled is recirculated within a closed loop, eliminating the need for make-up water and reducing water treatment costs....

A dry cooler is a cooling device that uses air to regulate the process temperature. The cooling is based on the principles of sensible heat rejection

A dry cooler is a type of heat exchanger that uses ambient air to cool a fluid, typically water or glycol, without direct contact between the fluid and the air. It relies on convection and conduction to transfer heat from the fluid to the air, which is then expelled into the atmosphere. Dry coolers are commonly used in […]

An adiabatic cooling tower is a type of heat rejection system that combines dry cooling and evaporative cooling principles to efficiently cool water or other process fluids. It’s designed to reduce water consumption and energy usage compared to traditional cooling towers, especially in warmer climates.  Here’s a breakdown...

Adiabatic cooling systems function similarly to dry cooling systems, but with the incorporation of pre-cooling pads; running water over pre-cooling pads and drawing air through the pads depresses the ambient dry bulb of the incoming air. The depressed dry bulb allows for greater system heat rejection. The result of this is that adiabatic...

A dry cooling system, also known as a dry cooling tower or air-cooled heat exchanger, uses ambient air to cool a fluid, typically water or glycol, without direct contact between the fluid and the air, thus avoiding water consumption. This is in contrast to wet cooling towers, which rely on water evaporation to dissipate heat.

Here’s a more detailed explanation: Closed-circuit system: Dry cooling towers are closed-circuit systems, meaning the fluid being cooled (often water or a water-glycol mixture) is contained within a closed loop and does not come into direct contact with the ambient air. Heat transfer via heat exchanger: Heat is transferred from the working...

Adiabatic cooling of air is an indirect evaporative cooling process air flowing through a closed-loop is pre-cooled to the desired temperature. Water channeled through an adiabatic system is evaporated as required. The state change from liquid to gas results in an energy transfer in the form of heat.
