Why do I need an outdoor unit with my RCAC?
The outdoor unit of a reverse-cycle air conditioner usually extracts heat from the indoors and moves it outdoors via pipes containing refrigerant gas. This cools the house. (You could not do this if the outdoor unit was indoors).
In heating mode, the aircon simply reverses this process to heat the house. The outdoor unit pulls in heat from the outside air (heat is still there, even in winter!) The pipes transfer this heat to the indoor unit, which then warms the room.
