Recap simpulse day webinar: Optimizing Automotive HVAC Systems for Comfort and Efficiency

In the rapidly evolving world of mobility, the role of heating, ventilation, and air conditioning (HVAC) systems is becoming increasingly critical. These systems not only ensure passenger comfort but also significantly impact overall vehicle

performance. However, simulating HVAC systems in automotive applications presents unique challenges due to their complexity.

Our online simpulse day focused on HVAC simulation for road vehicles, aiming to uncover how advanced simulation techniques can enhance comfort, efficiency, and vehicle performance.

Key Topics Discussed:


Dynamic Environmental Conditions

Automotive HVAC systems must adapt to varying environmental conditions like temperature, humidity, and altitude. Simulating these dynamic responses requires robust modeling techniques and real-time control strategies to maintain optimal comfort and efficiency.


Thermal Management Challenges

HVAC systems are vital for thermal management, especially in electric and hybrid vehicles where battery temperature regulation is crucial for performance and longevity. This requires complex simulations to understand the interaction between HVAC systems and other components like batteries and powertrains.


Validation and Verification

Ensuring simulation accuracy through validation against real-world data is essential. However, obtaining such data can be difficult, particularly in early design stages. Developing robust validation methodologies is key to building confidence in

simulation results.


Energy Efficiency and Sustainability Goals

As energy efficiency and sustainability become critical concerns, manufacturers must design HVAC systems that minimize energy consumption. Simulating the trade-offs between comfort, efficiency, and system performance involves sophisticated optimization techniques and comprehensive analysis.
