Spring starts soon. You’re probably still running the heating and thinking all is fine, but have you looked to the future?
Records from the Bureau of Meteorology show that average temperatures are increasing over the years. This means hot weather is coming. It seems that nearly every other year there’s a record-breaking day, month, or season. It’s all fine if you’re in an office all day with air conditioning, but what are you going to do when you get home?
There are a number of options when it comes to staying cool. Let’s take a look at some of them.
Fans are a great way to move air around a room. However, aside from moving the air they don’t actually do anything. Being in front of or under a fan provides some relief but the air is still hot.
Split systems are a great solution for a room. These days, split systems are commonly “reverse cycle” and can provide cool or warm air, depending on which mode the system is placed in. Using a refrigerant, much like your kitchen’s refrigerator, the system pumps compressed gas through pipes, then blows air over the pipes to either cool down or warm up.
A standard split system can have either a wall-mounted unit, a bulkhead unit or even a cassette mounted in the ceiling, blowing air in four directions from the centre of the room. In general, however, it really only works for one room, though the air will filter out to other rooms.
Some people go for individual systems from the important rooms. Others opt for a “multi-head” system, where multiple indoor units operate from a single outdoor unit. This is generally more expensive but takes up less space.
An evaporative cooler takes the air from outside and passes it over water-soaked pads, then blows the air through a duct system directly to the rooms you want to cool. The pads cool the air down and allow it to pick up micro-drops of water. This makes for filtered, cool, fresh air. Evaporative systems are the most economical cooling system as it uses little water and only needs to power a fan to blow the air.
During extreme weather, these systems can struggle. Either the air is too humid to pick up more moisture or just too hot to properly cool down.
Ducted air conditioning operates like a split system, with indoor and outdoor units. However, the indoor system is connected to a duct network, delivering either warm or cool air directly into your rooms and providing a comfortable temperature all year-round.
