Thermodynamic cycles, which are at the core of efficient and renewable heating and cooling technologies, rely on refrigerants for their operation. Many common refrigerants are greenhouse gases or have other potential impacts on the environment. Eurovent favours a balanced and holistic refrigerant policy that aims to reduce the environmental impact from refrigerants but also looks at the full lifecycle impact of the equipment, duly considers safety aspects related to the flammability and toxicity of certain refrigerants and is realistic about industrial and technological constraints sector by sector.
