As the name suggests, this system is designed by splitting the window air conditioner in two parts along dotted line
So, it has a fan coil unit fitted inside the room and condensing unit installed outside
The two units are connected by suction line and liquid line.
In some cases capillary is inside condensing unit and low pressure liquid is supplied through an insulated line 10 the fan coil unit.
The noise generation in a window air conditioner is mainly due to the compressor unit so, the split air conditioner ensures low noise level in the room.
It prevents blockage of the window, as fan coil unit can be installed on the wall of the room.
The fan coil unit has greater air throw than window air conditioner It is suitable for a room which has no outside wall, which is necessary for window air conditioner. However, split unit consumes more energy due to two reasons:
(i) There are two motors one in condensing unit and another in fan coil unit.
(ii) Compressor power requirement increases due to long refrigerant lines
Split air conditioner has no ventilation provision
These units are also available in 1,1.5, 2 and 5 TR
