Efficient and sustainable cooling with CO₂ as the refrigerant.
As awareness of climate change and environmental impacts continues to grow, choosing sustainable solutions in all aspects of our lives, including cooling technology, becomes increasingly important. Natural refrigerants like CO₂ are emerging as an eco-friendly and future-proof solution for cooling, particularly in ventilation systems. These refrigerants represent a greener alternative to traditional synthetic refrigerants, which are often associated with high greenhouse gas emissions and harmful environmental effects.
Ensuring Compliance and Strengthening Eco-Friendly Solutions
The EU’s F-Gas regulations play a critical role in phasing down HFC and HFO refrigerants, which have a high Global Warming Potential (GWP). These regulations impose strict limitations on the use of fluorinated gases, aiming to gradually phase them out in favor of more environmentally friendly alternatives.
Ban from January 1, 2027: Fluorinated greenhouse gases with a GWP above 150 will be prohibited in integrated cooling systems and heat pumps.
Ban from January 1, 2032: No fluorinated refrigerants will be allowed in integrated cooling systems and heat pumps for systems under 12 kW. For systems over 12 kW, the GWP must not exceed 150.
Shaping the Future of Cooling by Eliminating Harmful Substances
With the upcoming PFAS ban, the cooling and ventilation industry must adapt by phasing out harmful substances. PFAS, known as “forever chemicals,” pose significant environmental and health risks, prompting stricter EU regulations. To comply with these rules and future-proof cooling systems, the industry is working to replace PFAS-containing materials with more sustainable alternatives. This transition is crucial to protecting the environment and ensuring responsible and safe cooling technology moving forward.
CO₂ as a Refrigerant for a Better Future
CO₂ is a natural refrigerant with an extremely low Global Warming Potential (GWP) of 1, making it a far more environmentally friendly alternative to traditional synthetic refrigerants. As a naturally occurring substance, CO₂ emits significantly fewer greenhouse gases when used as a refrigerant, substantially reducing climate impact and causing no harm to the ozone layer.
By using CO₂ as a refrigerant in air handling units, systems remain unaffected by the revised F-gas regulations coming into effect in 2027 and 2032, thanks to CO₂’s low GWP of 1. CO₂ is a natural resource with stable and long-term availability, independent of geopolitical conditions or scarce resources, making it a reliable and environmentally friendly solution.
Air handling units using CO₂ as a refrigerant achieve high energy efficiency thanks to CO₂’s thermodynamic properties, which ensure effective heat exchange. This reduces energy consumption for both cooling and heating. CO₂ performs optimally in both low and high temperatures, making it an ideal choice for year-round operation.
CO₂ as a refrigerant offers high safety due to its classification in safety class A1. This means that CO₂ has low toxicity and is non-flammable, minimizing risks when used in air handling units. This combination makes CO₂ a secure and reliable choice for both industrial and commercial applications.
