Evaporative Air Coolers

Evaporative Air Coolers

Evaporative coolers offer a supply of cool, humid air that they circulate. They create a more comfortable environment in hot areas and on hot, arid days. Also known as bio coolers, swamp coolers, air coolers, and wet air coolers, these machines add moisture to hot air. The extra water in the atmosphere absorbs a lot of heat to evaporate. The phase transition from liquid water to vapour lowers the air temperature. The unit circulates the cooler air using an internal fan.

These machines use a simple concept, but they are effective. They are cheap to run, and you can use them in a wide range of well-ventilated indoor and outdoor spaces. Cooling a room using evaporation is a natural and ancient principle. Technology has allowed us to use the concept more effectively now. Although biocooling or adiabatic cooling is less well known than air conditioning, it is growing in popularity. There is more demand now because they are cheap to operate and easy to install. Evap coolers are also safe and healthy, portable, eco-friendly and do not use a refrigerant chemical.

Our range includes compact domestic and commercial, and industrial models. You can use them to keep customers and workers cool in hot conditions and during summer days. Some sectors have the opinion that air coolers are not designed for the UK weather, but, British weather actually offers the ideal climate conditions for evaporative cooling.

HOW DO THEY WORK?

Evaporative air coolers use the natural process of evaporation to cool air. Evaporative cooling is the conversion of liquid water into vapor using the thermal energy in the air, resulting in a lower air temperature. Internal fans circulate the new air around the local space. They feature an inner water tank, a water pump, cooling pads, and a fan. They pump the water from their water tank up to the top of the unit, where it flows back down and through the cooling pads. The internal fan draws warm air into the machine and passes it through the wet cooling pads. This process causes water droplets to evaporate into the air. The evaporation reduces the temperature of the air in a natural way, making it more comfortable. The internal fan then blows this cooler air out of the front of the machine for a cooling effect.

WHERE TO USE ONE

Evaporative air conditioners are best used in low-humidity well-ventilated areas. If the site is not well ventilated, condensation can often build up inside the space over time. So it is best to have windows open or doors open whilst using one of these machines.

You can use them in homes and hotels as long as there is a supply of fresh air. They are also great for commercial and public use, and shops, restaurants, bars, marquees, and gyms can benefit. As they are so versatile, you can also cool warehouses, factories, workshops, garages, etc, using adiabatic cooling. You can even use them in outdoor spaces like beer gardens and restaurant terraces.

WHERE NOT TO USE ONE

Do not use a wet air cooler in enclosed indoor spaces with no ventilation. The evaporated water will cause a rise in relative humidity and condensation. Never use one in an area containing sensitive equipment or materials. Museums and server rooms contain items that will react to increased humidity. Air conditioners offer the best option for cooling those areas.

EVAPORATIVE COOLERS V AIR CONDITIONING UNITS

The design of wet air coolers makes them perfect for well-ventilated indoor or semi-outdoor spaces. The design of air conditioners makes them great for enclosed indoor spaces with an open window to vent the warm air exhaust.

Evaporative air coolers only need electricity for their fan and water pump, so they use much less power than most air conditioning systems. As a result, air coolers are economical, energy-efficient, and far cheaper to run than air-con units. You do not need to install them or use outlet pipes or a water supply, so their placement is more flexible than monoblic AC.

When cooling indoor spaces with sensitive electrical equipment or items that will become damaged by a rise in humidity. They are not good for galleries, museums or server rooms. Air conditioners offer the best solution, they remove moisture from the air rather than add water. Read more here - Air conditioning Vs evaporative cooling.
