A type of fixed air conditioner in which the refrigeration cycle is divided into 2 units.
The outdoor unit houses the compressor, condenser coil and expansion valve and is designed to transfer heat to the outside by means of a centrifugal fan. The indoor unit contains the evaporator coil and, thanks to a tangential fan, blows cool air into the room.
Thanks to a special valve, the refrigeration cycle can be reversed to activate the heat pump mode. The outdoor motor acts as an evaporator to remove cold. The indoor unit condenses and blows hot air into the room.
Mono split systems can only condition 1 room.
