Abstract:
The first version of HVACSIM+, which stands for "HVAC
SIMulation PLUS other systems", as introduced by
National Institute of Standards and Technology (NIST) in
1985 as a computer simulation tool to simulate entire
building systems. Since then, the HVACSIM+ computer
program package and manuals have been distributed to
researchers, students, and consultants in more than 40
countries around the world. Since the first distribution
of the program to public, a number of modifications have
been made. Because some of statements in the Fortran 77
computer code of the HVACSIM+ used more than 20 years
have become obsolete in the context of today's Fortran
90/95 standards, an upgrade to Fortran 90/95 standards
was deemed necessary. This conversion task was recently
completed by NIST. During the conversion, the logic
flows were maintained as close to the original as
possible. This update manual is a condensed guide to
running the programs in the HVACSIM+ package. Much of
the substance of this manual is extracted directly from
the previous manuals. This manual is intended to update
and supplement the previous manuals, not to replace
them. To confirm correct operation of the new code and
illustrate its use, some of examples of system and
building shell simulations were chosen from the previous
documents. Simulation runs were made in the command line
interface of a popular operating system in step-by-step
manner. The input and output information of those runs
is listed in this manual.
