75 uses of air cooler

In extremely hot conditions regulating the temperature is extremely important if not lifesaving. Air coolers date back to ancient civilizations. In ancient Egypt, slaves used water jars with large palm fronds to fan and cool the rooms of their masters. This seems to have been a common practice of cooling houses in ancient civilizations.

A development of this form of cooling was the use of porous water pots that were built within the building’s walls, water from these pots would seep into the walls and keep the rooms cool during the heat of the day. This was the precursor to modern-day evaporative cooling systems.

Air coolers are heat exchange systems that soak up heat and release cool air. Modern air coolers are used to cool or dehumidify the air. Using brine water or many other coolants that run through copper or steel piping fitted on aluminum fins that dissipate heat.

Evaporative air coolers are the commonest cooling systems. Borrowing heavily from their ancient precursors, they absorb heat from their surroundings which heats and causes the water or coolant within to evaporate, releasing cooler humid vapor that causes a significant drop in the room’s temperature. In hot and dry conditions Evaporative coolers make buildings more comfortable.

There are two types of air cooling systems, dry air cooling systems which use vapor compression refrigeration cycles and evaporative cooling systems which use water or coolants are more passive, they consume less energy and are environmentally friendly. There are three types of Evaporative cooling systems:

1.    Direct evaporative air coolers.

2.    Indirect evaporative air coolers.

3.    Mechanical direct evaporative air coolers.

Direct evaporative air coolers use latent heat of evaporation in an open circuit to lower the temperature and increase humidity, the hot air heats up water in the air cooler, the warm dry air is changed to cool moist air cooling the house.

Indirect evaporative air coolers use a closed circuit, direct evaporative cooling with heat exchanging mechanism to transfer coolant to the air supply. The cool air is pumped into the room as a moist air stream is released to the outside with the use of a wet-bulb regulator.

Mechanical direct evaporative air coolers consist of a water pump, centrifugal fan, and a membrane. They use fans to draw air through a wet membrane pad.

The pump sprays water on the membrane pad which has a large evaporative surface, the water continuously drips down into the membrane the cooled air is released into the room, excess water is collected in a pan at the bottom of the membrane and recirculated back to the top.

Evaporative air coolers are best suited in hot areas with low humidity. Here are several jaw-dropping uses of air coolers:

1.    Industrial plants

Industrial units can operate at their optimum when in peak conditions, and performing under favorable conditions for the workers.
