Thermal Management Systems Symposium

October 2-3, 2024 | Plymouth, Michigan

Stay Up to Speed on Thermal Systems Technologies and Management

The TMSS technical program – created for engineers, by engineers – provides attendees with a wholistic look at the vehicle heating and cooling topics for all automotive thermal aspects, including autonomous and connected vehicles, commercial and off-road vehicles, and hybrid and electric vehicles. The program will focus real-world challenges and solutions on a global scale.

Technical program highlights:

  • Latest and most pertinent topics in the field of ground vehicle thermal systems technology and thermal systems management
  • Ground vehicles: commercial, heavy-duty, off-road
  • Climate, air conditioning, refrigerant, thermal management: engine, cabin, battery
  • Environmental regulatory requirements
  • Emerging and supporting technologies



*Our technical program is under development by engineering professionals from around the world. Additional papers/presentations are still under consideration. Session topics, dates and times may shift. The final program schedule will be available after August 20, 2024.

Driving the Change Towards New Refrigerants

Per - and polyfluoroalkyl substances – known as PFAS are man-made chemicals are widely used, are long lasting chemicals (also known as forever chemicals), components of which break down very slowly over time. Scientific studies have shown that exposure to some PFAS in the environment may be linked to harmful health effects in humans and animals. Because of their widespread use and their persistence in the environment, many PFAS are found in human and animals’ blood all over the world and are present at low levels in a variety of food products and in the environment. Both refrigerants (HFC-134a & HFO-1234yf) that are currently used in mobile air conditioning systems (MACS) create PFAS. Various countries are looking into banning chemicals that create PFAS. Natural refrigerants are being proposed as alternative refrigerants as they do not create PFAS. Propane (R290) and Carbon-Dioxide (R744) are being considered as alternate refrigerants for mobile HVAC systems for internal combustion engine (ICE) vehicles and for electric vehicles (EVs). However, propane is highly flammable, and carbon-dioxide operates at extremely high pressures that needs to be addressed.
