Air Conditionning System
There are four basic system categories: 1 Central chilled water air conditioning systems - All Air Systems 1.1 Single zone 1.2 Reheat 1.3 Variable Air Volume 1.4 Dual Duct 1.5 Multizone 2 Central chilled water air conditioning systems - Air-and Water Systems 2.1 Induction 2.2 Fan Coil 2.3 Two-pipe 2.4 Three-pipe 3 Central chilled water air conditioning systems - All Water Systems, including cooling towers which can also be applied to systems 1, 2 above 3.1 Fan-coil units 3.2 Central chilled water air conditioning system with fan coils and other devices 3.3 Water cooling tower 4 Direct expansion Systems [i.e. direct expansion of refrigerant, without the chilled water cooling medium ] 4.1 Window air conditioners 4.2 Unitary and Rooftop Air Conditioners 4.3 Split type and package air conditioning systems 4.4 Heat pumps
