Australia’s climate is becoming increasingly unpredictable, with rising temperatures, prolonged heatwaves, and changing humidity levels. In this shifting environment, evaporative coolers remain a popular and energy-efficient cooling solution, especially in drier regions. However, as climate patterns evolve, homeowners and businesses must ensure their systems are running at peak efficiency to maximise cooling performance and energy savings. This month, we explore how to get the most out of your evaporative cooling system, from regular maintenance to cooler repair when needed.
How Does Evaporative Cooling Work?
Evaporative cooling relies on the natural process of water evaporation to cool air. Hot, dry outside air is drawn through water-saturated pads, where it absorbs moisture, lowering the temperature before being circulated throughout a home or business. This process is highly effective in regions with low humidity, such as Victoria, South Australia, and inland Australia. However, efficiency can be compromised in areas experiencing increasing humidity levels due to climate change.
Tips to Maximise the Efficiency of Your Evaporative Cooler
Choose the Right Time to Run Your Cooler
Evaporative coolers work best in dry conditions, so their efficiency can fluctuate throughout the day. Running your system early in the morning and in the evening, when the air is driest, will produce the best results. It is best to avoid using the system during the most humid parts of the day, especially after summer storms, unless your unit has a humidity control feature. Monitoring local weather conditions and adjusting usage accordingly can help maintain efficiency.
Ensure Proper Ventilation
Unlike refrigerated air conditioning, which works best in a sealed environment, evaporative cooling requires proper airflow. To prevent your home from feeling damp or overly humid, it is important to open windows or doors to create a cross-breeze. This allows stale air to be pushed out and fresh air to circulate. Using ceiling or exhaust fans in conjunction with the cooler can enhance air movement. If running the cooler overnight, opening windows slightly can help prevent condensation build-up.
Maintain Your Cooling Pads
The cooling pads in your evaporative cooler play a critical role in the cooling process. Dirty or clogged pads reduce efficiency, forcing the system to work harder and consume more energy. It is essential to clean the pads at least once per season or more frequently during peak summer use. Water-efficient pads can also improve performance and longevity.
Regularly Clean the Water Reservoir and Pump
Water quality significantly impacts the efficiency of your evaporative cooler. Over time, mineral deposits, dust, and algae can accumulate in the water tank, reducing performance and leading to unpleasant odours. Flushing the reservoir at the start of each summer helps keep the system running efficiently. Checking the pump for blockages and ensuring it is circulating water effectively is also necessary. Using clean, fresh water can prevent bacterial growth and improve system efficiency.
Upgrade to a Smart Evaporative Cooler
Modern evaporative coolers come with advanced technology that can significantly improve efficiency, even in changing climates. Systems with humidity control can adapt to varying moisture levels, ensuring optimal cooling. Using smart thermostats to regulate cooling based on real-time temperature and humidity data can improve energy savings. Investing in Wi-Fi-enabled systems allows remote control and automation for even greater efficiency.
Schedule Regular Professional Maintenance
While routine cleaning and upkeep can be done by homeowners, professional servicing ensures the system operates at peak performance. A licensed HVAC technician can inspect and clean internal components, including fans and motors. Checking for wear and tear on belts, seals, and moving parts is also important to maintain efficiency. Ensuring the system is operating correctly and making any necessary upgrades or cooler repairs can help prolong its lifespan and improve performance, so it is important to schedule regular servicing and maintenance for your cooling system.
