In Vehicle Heating and AC Testing

In order to fully characterize and map the performance of a vehicle’s HVAC system, tests can be conducted throughout the system operating range and design conditions.  These include analyzing the performance of the system when faced with extreme conditions, analyzing the effects of cabin heating via solar load, mapping airflow, and optimizing the system refrigerant charge. The purpose is always to ensure maximum performance throughout the design conditions.


Tests may include but are not limited to:

  • Vehicle A/C Pull-Down Testing
  • Heating System Pull-Up Testing
  • Vehicle Level Refrigerant Charge optimization
  • Thermal Imaging
  • Windscreen Airflow Velocity Profile for Defroster
  • Solar Load Simulation for Cab A/C System Testing
  • Vehicle Defrosting Performance Test
  • Vehicle Defogging Performance Test
