Reverse cycle air conditioning has got a compressor outside; there’s a fan coil inside where cooling or heating refrigerant and passing that up through copper pipes up into a coil. That coil is either heated or cooled depending on what setting it’s on then we’re passing air that’s taken from inside your house across the across this heating or cooling fan and back into the home. So, it’s like it’s like a fridge… it is cold – you put your hand in there and it’s cold and like in your fridge the walls of the fridge cold everything is cold. In your home the chairs are cold the tables are called the curtains are cold, with evaporative cooling you’re taking air from outside the home increasing the humidity which has a cooling effect and delivering that through the home and out through the home – so you’re getting a cycle of fresh air in and out as opposed to recycling the same air through the house.
So that’s why the difference of living in reverse cycle air conditioning or living with evaporative cooling – if you’re living with reverse cycle air-conditioning it’s about locking that air in and allowing the air that you’ve already conditioned to pass back through the coil and continue to cool, so it it’s a cycle so it keeps taking the same air back across the coil and delivers it back to the home. So, when you’re cooling, you’re taking it down in step so each time it passes across the coil it gets a little bit cooler and keeps delivering that to your home.
With evaporative cooling you’ve got to get rid of the hot air so it’s about opening the house up and letting the air flow in and out. A very different feel in the home and a very different way that you live with both types to make them efficient and effective.
