Held on December 3, 2026! Next-generation vehicle interior climate control: Comparison of HVAC control based on air temperature and human thermal sensation.
The air conditioning system in the vehicle has the technical challenge of quickly ensuring passenger comfort while minimizing energy consumption. This is particularly important in electric vehicles (EVs), where energy consumption for air conditioning affects driving range and the design of thermal management systems, making it crucial to balance comfort and energy efficiency. Conventional HVAC control based on air temperature relies on the set temperature of the cabin, which can lead to a temporal mismatch with the physiological thermal response of the human body. As a result, excessive heating or cooling may consume unnecessary energy. In this webinar, we will present simulation cases comparing HVAC control based on human thermal sensation with conventional HVAC control based on air temperature. [Event Overview] ■ Date: December 3, 2026 (Thursday) 16:00 - 16:45 ■ Cost: Free ■ Format: Online ■ Organized by: ThermoAnalytics Japan *For more details, please refer to the related links or feel free to contact us.

basic information
**Main Lecture Content** 1. Comparison of HVAC Control Based on Air Temperature and Thermal Sensation - Introduction of a closed-loop control system that uses feedback from the human body's thermal sensation to more quickly predict and evaluate occupant comfort, thereby reducing energy consumption due to excessive temperature adjustments in the cabin air. 2. Evaluation of HVAC Control Using 1D/3D Coupled Simulation - Presentation of a simulation method that integrates GT-SUITE, TAITherm, and RapidFlow to evaluate transient thermal behavior and HVAC control. 3. Comparison of Energy Consumption by HVAC Control Methods - Quantitative evaluation of the differences in energy consumption and reduction effects between the conventional method that controls the overall air temperature in the cabin and the control method based on occupants' thermal sensation. 4. Effects of Combining with Local Comfort Devices - Introduction of the effects of local heating devices, such as seat heaters and steering wheel heaters, on reducing the load of the HVAC system and shortening the time it takes for occupants to reach a neutral thermal sensation. *For more details, please refer to the related links or feel free to contact us.*
