Air conditioning split systems are a type of air conditioning system that is used to cool and heat a single room or area. They are composed of two main components: an outdoor unit and an indoor unit. The outdoor unit contains the compressor, condenser, and fan, while the indoor unit contains the evaporator and blower. The two units are connected by refrigerant lines, which allow the refrigerant to flow between the two components. The outdoor unit is responsible for compressing and condensing the refrigerant, while the indoor unit is responsible for evaporating and distributing the cooled air. Air conditioning split systems are highly efficient and provide a great deal of control over the temperature of the room or area being cooled. They are also relatively quiet and require minimal maintenance.
