A Simple and Complete Guide To Understanding What Adiabatic Dry Coolers Are

Adiabatic cooling units work the same as dry cooling systems or dry cooling units, however, the pre-cooling plates, the running of the water over the precool pads, and drawing air through the pre-cooling pads lowers the surroundings dry bulb of the incoming air. The depressed dry bulb provides for improved heat dispersion in the system. As a consequence, adiabatic dry systems perform well in dry settings and consume less water than classic or standard evaporator units. Adiabatic units allow the needed cooling volume while occupying a very small scale footprint along with lower fan motor power than a dry cooler.

Adiabatic cooling works according to the principles of thermodynamics, in which energy (heat) is transferred as "work" from one medium to another without an actual mass exchange taking place. The adiabatic cooling process occurs when the pressure drops in a system causing volume expansion, resulting in "work" on the environment. The adiabatic dry cooler units use the pressure-temperature relation to chill or cool a variety of industrial cooling processes.

Adiabatic Dry Coolers

Principle

The adiabatic dry cooler uses humidified pads to pre-cool the ambient air entering the tower. Pre-cooling helps to reach a temperature that is lower than the room temperature. This pre-cooled air is then used to cool the process water or other coolant that you use. Regulate the fan speed independently. From a performance standpoint, adiabatic coolers can sometimes achieve lower chilled water temperatures as compared to cooling towers while also using much less water.

Application

The eco air series of dry coolers and condensers represent the latest advancement in thermal heat transfer research and development; eco air series adiabatic dry cooler units maximize heat indulgence with little or no water consumption, functioning as a dry cooler until they are able to reach the required capacity during dry operation. 100% recycled coils, aluminium pre-cooling fins and pads, V-configuration adiabatic coolers, and condensers provide significant cooling capacity in a small, low-profile housing.

Water and energy-saving advantages 

The adiabatic dry cooler can result in a lot of water savings. There is no evaporative cooling in the adiabatic cooler and no intermittent flushing that reduces water loss significantly. Furthermore, the drift in the closed environment of the cooler is completely eliminated, thus eradicating any water loss. Compared to conventional air-cooled systems, the adiabatic cooler requires almost half the energy to function. In dry mode, the cooler works with a low fan speed. The cooler can also be programmed to use extensive pre-cooling and operate at much lower fan speeds if used in a water-rich environment.

Heat and energy efficiency 

The adiabatic dry cooler uses cellulose grooved paper sheets that act as adiabatic cushions on both sides of the heat exchanger tubes. With their high cooling capacity, adiabatic pad sheets have a high evaporation rate; they also have a minimal pressure drop. Therefore, these pads are minimally invasive for the cooling process. The adiabatic insoles are protected from decomposition, and they are completely self-cleaning. The tubes are designed to be exposed to maximum airflow, and their advanced undulating rib design creates sufficient air turbulence within the unit to improve heat transfer efficiency.

Conclusion

The adiabatic dry cooler has many benefits and drawbacks too, before you opt for this cooler unit it is best and smart to conduct your own research, talk to experts like suppliers or manufacturers to gain more knowledge and information about the adiabatic dry cooler. You can also check with brands that have this type of cooling unit and what are the reviews on the various models offered by them. Check the pricing of the adiabatic dry coolers and pick the one that fits in your budget and also gets the required work done for you.
