The CARNOT toolbox contains models for thermodynamics/energy engineering with focus on HVAC systems.

Updated 10 Dec 2019

Carnot Version 7.0, 2019 for Simulink R2018b under BSD 3-Clause License

CARNOT is a toolbox extension for MATLAB SIMULINK. It is a tool for the calculation and simulation of the thermal components of HVAC systems with regards to conventional and regenerative elements. The CARNOT Toolbox is a library of typical components of these systems. It is organized in Blocksets like the SIMULINK Library itself. The handling of the blocks is exactly the same as in SIMULINK, so that users familiar with SIMULINK can directly use the new Blocksets in the same way.
