Air Conditioning and Heating Simulation

GT-SUITE provides mature, robust refrigerant circuit modeling 

Air Conditioning and HeatingSTATE OF THE ART SOLUTION

Refrigerant systems play an increasingly important role in modern thermal management systems. GT-SUITE’s highly-developed solver is robust and stable for two-phase circuits in transient conditions, even with zero flow. A vast library of refrigerant properties are included with the built-in property calculations from NIST REFPROP.

GT-SUITE can model traditional A/C systems as well as heat pumps, supercritical CO2 systems, multiple branch systems and more. Refrigerant circuits can be easily integrated with coolant circuits, cabins, and vehicle and powertrain models for complete system thermal and energy management. 

Air Conditioning and HeatingAPPLICATION HIGHLIGHTS

  • Robust Navier-Stokes based solver handles arbitrary initial conditions and zero flow — always stable
  • Faster than real-time calculation speeds enable efficient controls development
  • NIST REFPROP fluid properties source code built in
  • Model all A/C system components individually or as a complete system
  • Spatially resolved condenser and evaporators to capture phase change
  • Automatic component calibration: heat exchangers, compressors, etc.
  • Investigate heat pump systems with any refrigerant (R1234yf, CO2, etc.)
  • Model effects of oil in the refrigerant
  • Wide range of detail for cabin models ranging from 0D to high fidelity models for passenger comfort with GT-TAITherm

Advanced Features

  • Model effects of oil in the refrigerant
  • Predict and analyze passenger comfort with GT-TAITherm
  • Predict heat exchanger performance when geometry changes (scaling)
  • Analyze battery thermal management of two-phase cooling loop
  • Use predictive correlations to estimate performance based on HX geometry or auto-calibrate to performance data
