An air conditioning and heat exchange blockset for Simulink


  • Nonlinear model for simulation of multiphase fluids
  • Subcritical air-conditioning and refrigeration systems
  • Transient dynamics of fluid loops
  • Customizable working fluids
  • Multiple exchanger types and humid air modeling


The Thermosys Toolbox for MATLAB® and Simulink® is a suite of simulation tools for analyzing the behavior of air-conditioning and refrigeration systems (both steady-state and time-dependent). The suite consists of a number of Simulink blocks which are appropriate for either independent use or integration into larger Simulink simulations. Each block has user-tunable parameters to allow better simulation of practical systems.

Thermosys is a Simulink blockset, driven primarily through level 2 S-functions, and reads fluid information from supplied data files. Thermosys ships with fluid information for ammonia, carbon dioxide, air, glycol/water, R21, R134a, R245fa, R404A, R407C, R410A, R507A, and water. You can define your own fluids by supplying *.mat files with a specific data structure.
