A Graphical man Machine Interface for Modular HVAC System Simulation Programs.

The presentation of most HVAC simulation programs are out of date and batch processing type. Their use is complex and often requires a good data processing knowledge. Moreover, the data entry is usually long and the search for conceiving or typing mistakes is not easy. This present work shows how to update the simulation environment and how to satisfy the modem work station requirements by using a graphical manmachine interface. The proposal software CAMOSIM is developed through a modular system HVAC simulation program "TRNSYS ",using "a workstation under UNIX, with X-Windows and Athena widgets". This program is composed of two main modules : the first one enables to generate global model libraries and the other one specific applications.
