modelica library to model fluid dynamic of HVAC systems

Changes from version 2.0.1

• Increase of performance by: -> diminution of iteration variable via a better management of explicit and implicit variables -> use of functions rather than equation on non linear and high order equations

• Compatibility with the new front end of the Open Modelica software (Version > 1.14)

• Management of transport and diffusion equations via Partial Derivative Equations rather than connection between multiple components

Changes in version 3.1

1-Minor corrections: - polynomialFlow: correction required to work with the version 1.16 of openModelica - gasConstant_X of the air Air_H2 media: correction in its declaration

2-Major corrections: - Correction in the called fonction to computed the derivative function of the saturation density of the MoistAir media (f4dc8833) - Correction in the calcualtion of the derivative function of the saturation density of the MoistAir media - Correction in the "UpwindFirstOrder" model when the flow was in reverse direction

3-Enhancements - FanVentilation: works with multi-species media - The saturation pressure fonctions have been changed to work with a MoistAir bellow the triple point condition. It does not mean that the media can model a condensable moist air bellow the triple point conditions - "SimpleOpening" and "VerticalOpening" are replaced by a signle "Opening" component. The bouyancy effect is no longer handled by dicretising the opening other the height but by analytical integration of hydrostatitque pressure other the height of the opening. The opening (being an intrinsic vertical opening) - The horizontal opening can handle buoyancy effect when density at the bottom is lower than than at the top - All the openings can handle the altitude variation between opening and boundary nodes
