Introducing Thermosys 5.1

The THERMOSYS 5 Toolbox for MATLAB/Simulink® is a suite of simulation tools for analyzing the behavior of air-conditioning and refrigeration systems (both steady-state and time-dependent).  It was developed at the University of Illinois at Urbana-Champaign through sponsorship by the Air-Conditioning and Refrigeration Center (ACRC) and distributed by CU Aerospace.*

Key benefits include:

  • Nonlinear models suitable for simulation and control design of multiphase fluid dynamics associated with subcritical and transcritical air-conditioning and refrigeration systems
  • Capability to simulate transient dynamics, including startup and shutdown dynamics
  • Component models library with user-defined parameters for building customized systems models
  • Built-in fluid properties for air, ammonia (R717), carbon dioxide (R744), R21, R134a, R245fa, R404A, R407C, R410A, R507A, glycol-water mixtures, and water
  • Brazed plate heat exchanger models for condensers and evaporators
  • Humidity and condensation modeling for refrigerant-to-air heat exchangers
  • New for 5.1:  Electrical component models, data management tools, and simplified routing of flow parameters

Note: The toolbox requires MATLAB/Simulink®, and is compatible with MATLAB Version 2014a or later.  Earlier versions of MATLAB/Simulink® may be compatible, but are not supported.
