A split unit is a system that can both cool, heat and dehumidify air in a room, and is a good alternative to electrical heating.
Depending on the application, a split unit is a system that can both cool, heat and dehumidify air in a room. These systems also have a reversible cycle.
In order to cool the air within a building, it is the evaporator that delivers cold air, while the condenser releases warm air outside the building.
On the other hand, air within a building is heated by reversing the process, i.e. the evaporator functions as a condenser, releasing warm air inside the building, while the external condenser functions as the evaporator.
The cooling process can therefore be used to provide a fully air-conditioned indoor climate. A split unit is a good alternative to electrical heating.
