Thermal Management Service on Test Benches

Component and system development refrigerants, heat pumps at the thermal management system test bench

Thermal Management Service on Test Benches

Thermal management is a key topic in vehicle development that is taken into account in the development process right from the start. Valuable development steps can be taken at an early stage on a TC5:E5hermomanagement system test bench. By integrating calculation models and simulators/emulators, qualitative statements on systems, components and control strategies for cooling, heating and refrigeration circuits could be made at an early stage of development (without a vehicle). In addition, early testing of operating strategies is possible. In further phases of development (including series production support), problems can be reproduced and causes investigated in a reproducible environment.

  • Dynamic load cases on the thermal management system test bench and sharpening of simulations
  • Function and control development on thermal management
  • HIL with vehicle control unit and real cooling and refrigerant circuits
  • Innovative heat pump refrigeration cycles and concepts - analysis and optimization
  • Characteristic diagrams for coolant circuit control - Curve diagrams for actuator control
  • Refrigerant circuit system optimization - basic investigations and system adjustment
  • Investigation of system instability/assessment of critical load cases
  • Investigation regarding refrigerant displacements in the system
  • Safeguarding investigations of component requirements within the overall system
  • Oil circulation ratio hedges/oil fill rate surveys and recommendations.
  • Standard measuring programs for safeguarding e.g. SAE matrix, LCCP etc.
  • Refrigerant charging quantity regulations
  • Investigation of unexpected problems in series circuits - finding causes and solutions
