Thermal Fluid Library

The Thermal Fluid library is a tool for modeling and designing thermal systems. Thermal systems involve processes where heat and mass transfer plays a crucial role. So the focus lies on modeling processes with single and two-phase behavior of gases and fluids or gas mixtures. Applications include heat and power couplings, air conditioning, cooling systems, drying processes etc. The model elements of the library allow for fast model creation based on circuit diagrams. The Thermal Fluid library is a joint development of ESI ITI and SHERPA Engineering (France).

The following model elements are included in the Thermal Fluid library:

Thermal-Fluid Connection

Thermal-Fluid Port

Pressure Supply

Flow Source


State Sensor
