Air Conditioner Types Commercially available close coupled solutions can be divided into two categories: Open-Loop and Closed-Loop. Open-Loop Configuration Open-Loop configurations are not totally independent from the room they are installed, and air flows interact with the ambient room environment. In-Row Air Conditioners Row-Based Air...

Close Coupled Cooling is a last generation cooling system particularly used in data centers. The goal of close coupled cooling is to bring heat transfer closest to its source: the equipment rack. By moving the air conditioner closer to the equipment rack a more precise delivery of inlet air and a more immediate capture of […]

A closed-circuit cooling tower, or dry cooling tower, involves no contact between the air and the fluid being cooled. This tower has two separate fluid circuits, one in which the fluid is recirculated on the outside of the second circuit, which is a bundle of tubes through which the hot water is flowing.

Here’s a more detailed breakdown: Two Fluid Circuits: The defining feature is the presence of two distinct fluid circuits. Primary Circuit: This is the closed loop where the fluid that needs cooling (e.g., process fluid in an industrial application or water in a chiller system) circulates within a coil. Secondary Circuit: Water from the...

A closed-circuit cooling tower is a heat rejection device that cools a circulating fluid (like water or a water-glycol mixture) by spraying it over a coil through which the fluid to be cooled is flowing. It’s characterized by having two separate fluid circuits: one for the fluid being cooled, which remains isolated within a coil, […]

Combined Flow Configuration Combined flow is the use of both a heat exchange coil and fill for heat transfer in a closed circuit cooling tower. The addition of fill to the traditional closed circuit cooling tower design reduces evaporation in the coil section, reducing the potential for scaling and fouling. BAC’s combined flow closed circuit...

Principle of Operation Closed circuit cooling towers operate in a manner similar to open cooling towers, except that the heat load to be rejected is transferred from the process fluid (the fluid being cooled) to the ambient air through a heat exchange coil. The coil serves to isolate the process fluid from the outside air, […]

Closed circuit cooling towers, also known as evaporative fluid coolers, keep the system clean and contaminant-free in a closed loop. This creates two separate fluid circuits: (1) an external circuit, in which spray water circulates over the coil and mixes with the outside air, and (2) an internal circuit, in which the process fluid to […]

Overhead Heat Exchangers Generally, a heat exchanger of this type discharges air from the ceiling into the cold aisle whereas the exhaust air rises into the vents in the ceiling; in Close Coupled system cases, the units are positioned directly above the servers, making the cold air delivery and hot air return much more precise. […]

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...

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 […]
