There are three types of air conditioning - evaporative cooling, gas
heating and reverse cycle heating and cooling.
What is evaporative cooling?
Evaporative cooling is not something new. In fact there is evidence to
suggest that the Ancient Egyptians used a primitive form of evaporative
cooling in their temples and palaces some 4,500 years ago.
Evaporative cooling works on the principle of water evaporation. To
demonstrate this for yourself, spray some water onto the back of your hand
and then slowly blow over it. You'll notice how the patch of skin where
the water was feels cooler. A further example is the effect of the sea on
the beach, where water held as moisture in the sea breeze cools down the
beach.
What is Refrigerated heating and
cooling?
Refrigerated heating or cooling or "Reverse cycle systems" as they are
commonly referred to, work through a very efficient heat pump to generate
either cooling or heating. Reverse cycle systems come in many forms and
range from single wall unit mounted splits to ducted systems with
independent control over each room.
When do you want evaporative cooling and when do
you want a refrigerated system?
Which System is best for you depends on what you want from air
conditioning, what you need and how much you have to spend. The best way
