Shutdown your Evaporative Coolers for Winter
Now that Adelaide is experiencing colder and wetter weather, you need to give your evaporative airconditioner an end of season shut-down. Not only will this improve the heating efficiency of your home, it can increase the Life and long-run performance of your cooling system. Frequent use over Summer can wear the components of your evaporative system, affecting long-term reliability and efficiency, all this should be checked at Shutdown.
Dirt and grime
Entering your unit over the course of a year and scale build-up from Adelaide’s hard water, can also affect your cooler. Dirt and scale on your pads decreases water absorption and evaporation, reducing its ability to cool. Over time, materials stuck on your pads can cause them to lose their shape, drastically reducing performance, potentially leading to problems in the main unit and water damage inside your home. Electrical faults within evaporative air conditioners have been known to cause dangerous roof fires, with the added danger of your unit’s ducting will provide a conduit for the flames to spread throughout your home. Shutting Down for Winter is critical for Evaporative AC’s.
Although filter pads would appear to be of good condition, sometimes over a span of years, efficiency has been lost due to a breakdown of the actual construction of each fibre and a clogging of strands of fibre by mineral deposits leached from the water, and airborne dusts. Between 20 – 40% efficiency is lost over a 12 month period, so replacement of pads for maximum coolness during our hottest days, is most desirable. For maximum efficiency we recommend changing of Aspen Woodwool filter pads every 18 months – 2 years, and CELdek pads 2 – 4 yearly, providing pads have been cleaned on a regular basis to prevent build up of deposits. To prolong the life of your pads, you could turn off the cooling cycle (pump) 5-10 minutes prior to shutting down the fan. This helps to dry the pads out before the unit is shut down, therefore preventing a suitable environment for algae (which can cause an unpleasant smell) when there is no airflow. The most important way to prolong the life of your pads is to shutdown the evaporative airconditioner for Winter.
