UNITARY AND CENTRAL AIR CONDITIONING SYSTEMS

A unitary or package air conditioning system uses equipment where most or all of the basic components have been assembled in the factory e.g., room air conditioner (Fig. 52.5).

A central or built-up air conditioning system uses equipment centrally located in mechanical equipment rooms. Each piece of equipment is installed separately and connected on the job, rather than manufactured as a package.
