Presentation of PRESIM - a user-friendly preprocesssor for TRNSYS

ABSTRACT PRESIM is an interactive graphical computer program for producing input data for modular HVAC system simulation programs. Version 1.0 runs on IBM compatible DOS computers and produces input data for the TRNSYS simulation program, version 12.2. The user works with a drawing of an HVAC system model on a graphical computer screen, much in the same way as with a CAD-system. PRESIM has been tested for half a year by experienced TRNSYS users and is now officially released and available through SERC and other distributors.
