Carrier Transicold Donates NaturaLINE Units to Technische Universität Berlin to Advance CO2 Refrigeration Research

Carrier Transicold is contributing two NaturaLINE® refrigeration units to Technische Universität Berlin (TU Berlin) to aid research into transcritical carbon dioxide (CO2) refrigeration technology. This will help develop cooling systems to meet environmental and regulatory standards in the global cold chain. Carrier Transicold is a division of Carrier Global Corporation, a prominent provider of climate and energy solutions.

The NaturaLINE system employs natural refrigerant, CO₂, which has a global warming potential (GWP) of 1, making it a lower-GWP option compared to synthetic refrigerants used in commercial cooling. TU Berlin's Institute of Energy Engineering will utilize the NaturaLINE units as practical learning aids for graduate students, enabling them to measure temperature profiles, system pressures, and power consumption for better understanding of transcritical CO2 systems and contrasting them with conventional refrigeration cycles.

The units will also serve as part of the institute's research infrastructure, allowing researchers to integrate and evaluate prototype components for developing and testing future heating and cooling systems. Performance will be assessed through automated test sequences and long-term evaluations under diverse operating conditions.

Professor Stefan Elbel, Chair of Heat Transfer and Heat Conversion at TU Berlin, expressed excitement about accessing next-generation technology and hopes this fosters a long-term research collaboration with Carrier Transicold. Jean-Marie Carvalho, Vice President & General Manager, Global Container at Carrier Transicold, emphasized the importance of transcritical CO2 systems and the company's support for TU Berlin's Institute of Energy Engineering's work, aiming to accelerate understanding of system performance and contribute to more sustainable cold chain solutions.
