ATMOsphere MAC Summit 2025 x TU Berlin
Berlin
Natural refrigerants for mobile air conditioning, heat pumps, and transport refrigeration
ATMOsphere MAC Summit is a joint event between ATMOsphere and Technische Universität Berlin‘s Chair of Heat Transfer and Heat Conversion.
The programme will feature presentations on state of the art in cooling and heat pumping with natural refrigerants for the mobile application and transport refrigeration, as well as optimal thermal management for EVs with natural refrigerants.
There will also be a parallel technology case study session on transport refrigeration applications with natural refrigerants.
