The Thermosys Toolbox for Matlab® is a software package for simulating and analyzing the behavior of air conditioning and refrigeration systems. This software and the related research was sponsored by the Air-Conditioning and Refrigeration Center at the University of Illinois at Urbana-Champaign.

Key Benefits

• Simple models for simulating the complex multi-phase fluid dynamics associated with air-conditioning and refrigeration systems.

• GUIs for entering the necessary component parameters

• Built-in refrigerant properties for R22, R134a, R404a, and R744 (CO₂)

• Nonlinear models suitable for simulation and linear models suitable for control design

• Sample system models, including: subcritical, transcritical, and multi-evaporator systems

• Open architecture code suitable for customizing
