Some rooms do not have external windows or walls. Difficulties arouse in creating sufficient air flow in the rooms, which can lead to discomfort for residents in terms of temperature and humidity.
The split-type air conditioner can be used in these situations.
Introduction:
A split air conditioning simply means that the condensor (or sometimes referred to as the “outdoor unit”) is separated from the “indoor unit”, thus the term “split”.
The split air conditioning has at least one unit that sits inside your room. The compressor sits outside of the room, sometimes on the ground or on brackets hung to the wall. Some models come with multiple indoor units that will use one single compressor, this is known as the multi-split air conditioning system.
In a split air conditioning system, the amount of cold air entering the room can he controlled by a thermostat or it can be regulated by an infra-red remote control, like a TV remote. One room or one area of a building can maintain a different temperature from another room or area in the same building. Split air conditionings are the perfect solution for spot cooling - for example, in residential houses where only certain rooms are required to be cooled at certain times like a living room during the day and a bedroom at night but also in large structures like retail stores and supermarkets, where spot cooling is essential in areas which can be either too hot or too cold.

The Split type air conditioning units have become very popular and have dominated the market in recent years. They are available with the indoor unit mounted on the wall, into the ceiling space, under the ceiling or on the floor.(Alexander, 2008)
A Split system may be used when the home has a forced warm-air furnace with a blower and a duct work.
