So what does ‘reverse cycle’ actually mean?
Reverse Cycle Air Conditioning systems work on the heat pump principle. As the name suggests, they pump heat from one place to another. Allow us to get a little scientific here, as we explain how heat pumps work
- A fan draws hot air from your home over a cold liquid, called a refrigerant. Heat is absorbed from the air, cooling it. The air then flows back into your home.
- The refrigerant, warmed from the hot air, evaporates and flows into a compressor, which creates a high-pressure, high temperature gas.
- The gas is pumped through a heat exchanger outside your home, which allows heat to escape and the refrigerant to cool and liquefy again.
- The refrigerant flows through an expansion device that lowers its pressure, cooling it further, so it can absorb heat again.
- Reverse-cycle air conditioners, as the name suggests, can reverse this process and be used for both cooling and heating.
