A split AC wall unit is a type of air conditioning system that is installed directly into the wall of a room or building. It is a two-part system, with the indoor unit mounted inside the wall and the outdoor unit mounted outside. The indoor unit contains the evaporator, condenser, and fan, while the outdoor unit contains the compressor and condenser. The two units are connected by copper pipes that run through the wall. The wall split AC unit is an efficient and effective way to cool a room or building, as it does not take up much space and can be installed quickly and easily. It is also more energy efficient than other types of air conditioning systems, as it does not require ductwork or a large amount of space. The wall split AC unit is a great choice for any home or business that needs a reliable and efficient cooling system.
