The Eiffel Tower has replaced its ageing cooling system with a new system using ultra-low-global-warming-potential (GWP) refrigerant.
The installation, which uses Honeywell’s Solstice ze (R-1234ze) refrigerant, provides the tower’s west pillar which houses the Eiffel Tower visitor information centre, a souvenir shop and a hydraulic life, with an energy efficient and cost-effective solution that reduces greenhouse gas emissions.
The Société d’Exploitation de la Tour Eiffel (SETE), which operates the tower, replaced its ageing system with a high-performing, sustainable alternative with increased reliability, energy efficiency and improved safety to help meet EU regulations and reduce the tower’s carbon footprint.
In combination with the variable speed of AF Energy’s compressors and condensers, Solstice ze delivers energy efficiency far surpassing the Eiffell Tower’s previous cooling system. In comparison to R-407C, which has a high GWP of 1774, Solstice ze has an ultra-low GWP of 1, which is 99.9 percent lower than the legacy refrigerant.
