What is the difference between a reverse cycle and an evaporative cooler?


These two cooling systems are often taken to be using the same technology, but in truth they are completely different. Before you decide which one is best for you, know their main difference and see which one fits your needs the most.

The reverse cycle air conditioning process uses a compressor outside and a fan coil inside where cooling or heating refrigerant passes through depending on the setting it’s on. Air taken from the inside of the house is then passed across the heating/cooling fans and back into the home. So it’s like a fridge, you put your hand in there and you can feel the cold, and like the fridge you can feel every object in your house going cold.

With evaporative cooling, you’re taking air from outside the home and increasing the humidity, which has a cooling effect, and delivering that through and out the home. This gives a cycle of fresh air in and out, as opposed to recycling the same air through the house. The advantage of this is that you are making the air inside your house at a steady temperature that is more bearable and fresh as well.

That’s the main difference between these two. With reverse cycle air conditioning you are locking conditioned air in, passing it through the coil again to continue cooling. It’s a cycle that keeps taking the same air back in across the fan coil and delivering it back to the house. Each time it passes through the fan coil it keeps getting cooler and keeps delivering that to your home.

With evaporative cooling you have to get rid of the hot air, so it’s about opening the house up and letting the air flow in and out. It’s a very different feel of the home and a very different way of using both types to make them more efficient and effective.
