Heating. In winter, the reverse-cycle system extracts heat from outside air and draws it inside. … This hot air is then pumped out by a fan, out into the room. Once this is completed the refrigerant flows through another evaporator to cool it down before being pumped back into the condenser to repeat the cycle.
What is the difference between reverse cycle and split system air conditioners?
A reverse-cycle air conditioner can heat as well as cool – in fact, it’s one of the cheapest ways to heat your home in winter.
