Evaporative Cooling

What is Evaporative Cooling?

As the name suggests, evaporative cooling is a type of cooling system. It employs the basic principle of evaporation to cool air.

An evaporative cooler has a unit mounted on a roof that takes in hot and dry fresh air from outside. As the air draws in, it passes through soaking-wet cooling pads that evaporate heat and reduce the air temperature.

The cooled air then circulates through the home via ductwork and vents. When in operation, it is important to leave a window or door open. This is so the hot air in a room can move out and cool air from the vents can move in.

Evaporative air conditioning suits a variety of homes and works well in most climates. However, it is not typically recommended for areas with high humidity.

How are Evaporative Coolers Different?

The evaporative air conditioner, popular in many Australian homes, differs considerably from traditional air conditioning systems. Though they both provide cooling, they operate on different principles.

Traditional systems work on refrigerated air conditioning; they use refrigerants to absorb and remove heat from the air. The process requires more energy and often results in dry indoor environments. On the other hand, the evaporative cooling process involves cooling the warm air by evaporating water.

This process both humidifies and lowers the air temperature. This makes them especially suitable for Australia's dry climates, but less effective in areas with high humidity.

For Australian homeowners, choosing between traditional air conditioning and direct evaporative cooling often comes down to the climate in the local area, energy consumption preferences, cooling capacity and desired indoor air quality.

The Benefits of Evaporative Cooling

Evaporative cooling offers a wealth of benefits for homes in the right climate conditions. They include:

• Energy efficiency: Evaporative coolers use significantly less electricity compared to conventional air conditioners, reducing energy bills for homeowners.
• Eco-friendly: The natural evaporative cooling process uses no refrigerant gases, ultimately keeping environmental impact to a bare minimum.
• Better quality of air: Evaporative systems continuously circulate fresh, filtered air, drawing out airborne particles from inside the home.
• Optimal in dry climates: Especially effective in dry air regions, common in Australia, providing cooling and adding necessary humidity to the air.
• Comfort: Delivers cool, moist air, preventing dry eyes and skin during hot seasons.
• Operational simplicity: User-friendly controls make it easy for homeowners to manage cooling efficiently.

Whether you have ducted evaporative cooling or use portable evaporative coolers in your home, you're sure to benefit from their general cooling power.

24/7 Evaporative Cooler Services

Metropolitan Heating recommends regular servicing of evaporative coolers to maintain their performance and energy efficiency. A ducted evaporative cooler, for example, attracts birds, mice and spiders in the cooler months.

So, a regular servicing schedule will ensure these are kept away. Consistent maintenance will also prolong the lifespan of your cooler and prevent minor problems from turning into major, costly issues.

At Metropolitan Heating and Cooling, we provide 24/7 evaporative cooling services to keep your home comfortable during hot spells. Whether you have residential evaporative coolers or single stage evaporative coolers, our team is ready to help any time, day or night.

If you live in a hot and dry climate, evaporative cooling works best by drawing in warm air, passing it over wet pads, and releasing cooler air inside your home.

The cooling efficiency depends on the dry bulb temperature (air temperature) and the wet bulb temperature (humidity’s cooling effect). These systems are less effective in humid climates, where temperature and humidity are both high.

Still, they’re a great energy-efficient option for many Australian homes. If your evaporative cooling devices need maintenance or repairs, give us a call – we’re here when you need us most.

Stay Cool Throughout Summer

When the heat hits hard, Metropolitan Heating and Cooling helps you stay cool with efficient evaporative cooling systems.

Evaporative coolers work by drawing in warm ambient air and passing it through water-saturated pads. As the water evaporates, it absorbs heat energy, lowering the air’s temperature and boosting air movement throughout your home.

This natural cooling process improves comfort and indoor air quality by pushing out stale air and replacing it with fresher, cooler air. Unlike traditional refrigerated systems, evaporative coolers perform best in dry climates and are energy-efficient while still delivering excellent cooling performance.

With the right setup, you’ll enjoy a noticeable drop in ambient temperature and a system that can provide sufficient cooling throughout your home all summer long.
