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 ]
