\n\t\t\t\tA Safe and Sustainable Heat Pump Solution\t\t\t<\/h2>\n\t\t\t
\n\t\t\t\t

This project aims to develop a next-generation heat pump using natural, non-flammable, and non-toxic refrigerants<\/strong>: water and CO\u2082<\/strong>. By combining these two abundant and environmentally neutral fluids<\/strong>, the system offers high performance without the risks linked to conventional refrigerants.<\/p>\n

Laboratory testing<\/strong> and digital modeling<\/strong> will validate the concept and assess its energy efficiency<\/strong> and environmental impact<\/strong> through Life Cycle Assessment (LCA)<\/strong>. The project supports the European ecological transition<\/strong> by laying the foundation for a safe, efficient, and regulation-resilient heat pump technology<\/strong>.<\/p>\n\t\t\t<\/div>\n\t\t\t

Natural refrigerants are a promising alternative, but each comes with limitations: water-based heat pumps struggle in cold climates, CO\u2082 systems lack heating efficiency, and other options like propane or ammonia are flammable or toxic, restricting their use.<\/p>\n<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t
