System Requirements

* PC system computer or compatible computer
* 256 megabytes of memory 
* 100 megabytes of hard disk space 
* Fortran 90/95 compiler for development of source code
* PDF file reader for reading manuals 

Installing HVACSIM+    

1. Create a folder/directory (e.g., HVACSIM20) on a hard drive.
2. Copy all files on the CD into the folder.
3. Make a working subfolder (e.g., WORK) in the folder.
4. Copy the files in the folders, BIN and DATA, into the working folder for an initial run.
5. The folder DOC contains manuals in PDF format, and the folder SAMPLE contains the inputs for sample runs.

Note

(1) Every component model as TYPEn should include at least one parameter variable, PAR.

(2) Whether used or not, the boundary data file (default file name: HVACSIM.BND) must be present during simulations.

(3) As a default, the simulation summary file (default file name: HVACSIM.SUM) contains simulation outputs up to 3600 seconds.  If desired, change the value of WRTMAX in the file MODSIM_HEAD.F90.
