Air Conditioning - Split

Split air conditioners - essentially two component elements, an inside bit that delivers the cool air and an external bit that discharges heat, that are connected by refrigerant pipes, so that the two elements when linked form a refrigerant circuit. The big benefit of split air conditioners is that the noisy bit, i.e. the compressor, is outside. Also the refrigerant pipes, or 'umbilical cord', is usually far easier to route through a door or window than a exhaust duct on a monoblock. Also there is usually very little penelty to having longer refrigerant pipes if say the outside is a distance from the cooled room.
