WHAT COOLING SYSTEMS ARE VICTORIANS CHOOSING THIS SUMMER:
Victoria’s choice in cooling systems have become the ducted evaporative coolers as they can generally provide adequate cooling to the entire household. A popular choice for cooling smaller rooms and for providing spot cooling, Victorians seem to be going with window mounted and portable evaporative coolers.
HOW DOES AN EVAPORATIVE COOLER WORK?:
An Evaporative cooler works by drawing in the warm outside air via water filter pads. These pads are supplied with water found in a tank at the bottom on the unit. The water from these pads evaporates, drawing heat from the air and humidifies it. This air is now cooled and moist and is blown through out the home or space.
COST OF RUNNING AN EVAPORATIVE COOLING UNIT:
Both electricity and water are required to run an evaporative cooling unit. Approximate maximum hourly running costs for how much electricity it may use are provided below, however actual costs will depend on the cooling capacity of the unit and the fan speed that it is being run on.
- portable units cost 2 to 3 cents per hour
- window/wall-mounted units cost 6 to 7 cents per hour
- ducted units (medium size) cost 12 to 28 cents per hour.
WATER CONSUMPTION FOR YOUR EVAPORATIVE COOLING UNIT:
The amount of water used is dependable on the amount of humidity that day and the fan speed that you have set your unit to. A portable unit may use up to approximately 4 litres an hour in comparison to a central system which can use up to 25 litres an hour.
A ducted evaporative cooler has to refresh its supply of water in order to ensure it doesn’t become too salty, so there are a range of water management systems being uses depending on the model you have got. Therefore we suggest that prior to purchasing a unit you ask about the water management system used and what it typically uses in water consumption per hour.
A range of water management systems are used by different brands/models. If you are purchasing a ducted evaporative cooler, ask about the water management system used and what the typical hourly water consumption is likely to be in your area.
WHAT SIZE EVAPORATIVE COOLER IS BEST FOR YOUR HOME?:
Different sized evaporative coolers are suited to different areas depending on the amount of airflow and the volume of the area which you are wanting to be cooled. The best thing for you to do prior to purchasing a unit is to seek an accurate sizing quote from either an installer or from your local retailer. They are trained to best consider your local humidity levels along with the size of your home or space.
TIPS FOR OPERATING AN EVAPORTIVE COOLER
- Make sure all windows and doors are being kept open in rooms that are being cooled and ensure the opening is big enough to allow air to flow outside with ease. The effect of cooling will be reduced if there is insufficient openings and may put extra pressure on the fan.
- Reduce heat gain by opening windows and doors on the opposite side of the house to the hot prevailing winds where possible
- For units that have a timer, set it to switch off the system when cooling is not required for example in the early morning.
- On days of high humidity, turn off the water supply to the cooler and run the fan only – this can also be quite effective on still humid evenings if the outside air has cooled down
