CH-85-16-2 -- Simulation of a Multizone Air Handler PDF

A detailed simulation of a large HVAC system is described. This simulation is intended to demonstrate the capabilities of a new modular simulation program – MODSIM – which has been developed as part of a building system simulation package. The system chosen for this demonstration is a multizone air handler serving two zones. This system is a typical HVAC subsystem and is large enough to demonstrate the capability of MODSIM to carry out detailed simulation of complete building systems under complex operational conditions. Three simulations are presented which demonstrate the system performance during a simplified morning startup situation for different control methods.
