The basic branches of airconditioning are Central AC systems and Non-central AC products. Central AC Systems can then be divided into Ductable Packaged Airconditioners and Central Plants, while Non-central AC Products can be divided into Window ACs and Split ACs. Further subdivisions appear in subsequent pages.
As illustrated in Figure, Airconditioning falls into two broad segments:
Central AC Systems and Non-Central Ac products.
By Non-Central AC Products we mean those airconditioners that do not use any air ducting to cool the conditioned space.Window mounted ‘Room Airconditioners’ and the ‘Non-Ducted Split Airconditioners’ fall into this category. Thes products are suitable where air throw is limited to around 4 metres (13 feet) and small spaces are involved. Where large spaces are involved, multiple units are to distribute the air.
