Clayton Miller, Chandra SekharNational University of Singapore, SingaporeAbstract: This paper outlines the conceptual development of a building energy simulation model for the Single
Coil, Twin Fan Air Conditioning (SCTF) system in the
whole building simulation program EnergyPlus. The
SCTF system is a unitary, multi-zone system which
conditions the outdoor ventilation and recirculated
return air in two separate streams through a single
compartmented cooling coil and supplies these
unmixed streams via two variable speed fans and a dual
duct arrangement to zonal mixing boxes. The main
challenges addressed in EnergyPlus include the existing
inability to concurrently simulate unmixed air streams
within a centralized VAV system, supply and control
outdoor air and recirculated air independently to a
space via dual duct network, and prediction of
performance of a compartmented cooling coil – all of
which have potential applications in other innovative
systems. Pages: 201 - 206 Paper:
