The split air conditioner as the name suggests is made of two different parts. It has an indoor unit and an outdoor unit. The use of split air conditioners is quite prevalent in homes and studio settings. Slowly, the popularity of this air conditioning system is gaining ground for use even in small commercial set ups.

The Overview of Split Air Conditioner
The outdoor unit resides outside the room and this unit includes the compressor and condenser. The outdoor unit weighs quite heavy because of presence of compressor and the condenser. The indoor unit is much lighter in weight than the outdoor unit and has the cooling fan and the evaporator coil. The evaporator coil from the indoor unit is connected to the condenser of the outdoor unit. The connection between the two is established using refrigerator piping. The indoor unit is suspended from the walls of the room while there are some indoor units that can be installed inside the ceiling cavity as well. The indoor unit has vents through which the cold air is pushed to cool the surroundings. The vents are directional and they can be adjusted for channelizing the flow of air.
Indoor Unit, Parts and Components
The split air conditioner indoor units are quite compact in size and absorb lesser space in the room. These units are much more sophisticated look much better in design then the traditional humongous window ACs. The indoor units of these air conditioners are aesthetically pleasing. The indoor unit comprises of:

- Air Filter – The air filter removes or filters the dust particles in the air keeping the indoor unit clean and circulating the room with dust free air. The air filters are placed just above the cooling coils where they block the dust particles when the blower sucks the hot room air and allows the clean air to pass through.
- Blower or Cooling Fan – The indoor unit has a blower that sucks the hot and humid air of the room and passes it over the cooling coils. While the blower sucks the hot air it is also responsible for supplying the cool air back in the room. The blower is connected to a motor with multiple speed regulator which helps maintain and alter the speed of the blower.
- Drain Pipe – The cooling coils operating below dew point collect a lot of moisture due to condensation. This moisture is removed from the room and collected in a pan within the indoor unit. This water collecting pan is further connected to a rubber drain pipe which takes this excess water and drains it outside the room in a safe place or on the ground.
- Louvers or Directional Vents – The cooled air by the blower is passed to the room through the louvers. Louvers are of two types: horizontal ones and the vertical ones. These louvers, are also called fins. They are used to channel the direction of the air that passes from the blower to the room.
The Working of Split Air Conditioners
The evaporator in the split air conditioner is responsible for removing the humidity from the room air. In principle, the evaporator runs and maintains a temperature which lies below the dew point as a result of which the moisture in the surrounding air gets condensed on the evaporator’s coil tubes. The evaporator tubes are connected to a pan where this excess of moisture is collected in the form of water. This water is drained out from the unit with the help of a connected rubber tube.
