Designing energy-efficient HVAC systems for improved passenger thermal comfort

Balance efficiency, comfort, and optimal performance in all driving conditions with an integrated workflow

Estimated Watching Time: 54 minutes

Designing HVAC systems for the passenger cabin used to be straightforward, as the heat generated by the internal combustion engine was redirected to the HVAC unit. For electric vehicles, this is an entirely different story. A battery-powered car does not have large amounts of wasted heat to work with. Today, the challenge for thermal engineers is quantifying trade-offs between energy efficiency, passenger comfort, and vehicle performance.

This webinar explains how to capture the local thermal comfort of passengers by combining detailed high-fidelity simulation of passenger comfort with close to real-time simulation to design efficient control systems. Additionally, we demonstrate how to link these models to a system model to understand the overall energy consumption of the HVAC system. Register now!

Register for the webinar and discover an integrated workflow to:

  • Design efficient cabin HVAC systems
  • Size components such as heat pumps, compressors, heat exchangers and meet cabin cooling requirements
  • Calculate passenger thermal comfort using detailed CFD modeling
  • Examine local thermal comfort caused by radiant heaters or heated/cooled seats
  • Assess energy savings of radiant heaters, heated/cooled seats
  • Feed complex 3D CFD simulation into a reduced-order-model (ROM)
