The split systems are individual systems in which the two heat exchangers are separated (one outside, one inside). There are two main parts of the split air conditioner which are:
1. Outdoor unit.
2. Indoor unit.
1- Outdoor unit:
This unit is installed outside the room or office space which is to be cooled and houses important components of the air conditioner like:
The compressor,
Condenser Cooling Fan,
Expansion Valve.
2- Indoor unit:
The most common type of the indoor unit is the wall mounted type though other types like ceiling mounted and floor mounted are also used. The indoor unit produces the cooling effect inside the room or the office and houses the following components:
The evaporator coil or the cooling coil,
Cooling Fan or Blower,
The drain pipe,
Louvers or Fins,
Air filter,
Controls.
The split air conditioning units are fed from either:
Single phase power source (as in the video), so its branch circuit and its main power cord consisting of 3 wires (The ground wire, hot wire and neutral wire).
Or
Three phase power source (not included in this video, but same concept), so its branch circuit and its main power cord consisting of 5 wires (The ground wire, 3 hot wires and neutral wire).
