The project in brief<\/h2>\n

Project Background and Objectives<\/h3>\n

In a regulatory context favorable to non-synthetic refrigerant fluids<\/strong>, the aim of the project is to achieve proof of concept<\/strong> for a heat pump (HP)<\/strong> using natural, non-flammable and non-toxic fluids: water and CO\u2082<\/strong>. The novel combination<\/strong> of these two abundant and inert fluids<\/strong> makes it possible to exploit the thermodynamic advantages of each while cancelling out their disadvantages<\/strong>. The use of water and CO\u2082<\/strong> stands out from the use of hydrocarbon and fluorinated refrigerants<\/strong>, which are respectively highly flammable<\/strong> and harmful to the environment<\/strong>.<\/p>\n

Methodology and Environmental Impact<\/h3>\n

Laboratory tests<\/strong> in a simulated environment<\/strong> (climatic chamber and hot water network<\/strong>) will be used to validate the concept<\/strong> and create a data-driven model<\/strong>. This model will be used to carry out an energetic and environmental assessment<\/strong> of the solution for real-life use cases<\/strong>, simulated by building thermal models<\/strong> and a Life Cycle Assessment (LCA)<\/strong>. The LCA<\/strong> can then highlight and help to improve<\/strong> this solution\u2019s comparative advantage<\/strong> over others in terms of environmental impact<\/strong>.<\/p>\n

The approach therefore involves several scales of analysis<\/strong> (from component to system<\/strong>) in order to correctly quantify the HP\u2019s performance<\/strong>, and is also cross-cutting<\/strong> as it focuses on technological innovation<\/strong> and environmental impacts<\/strong>, which we consider essential<\/strong> to guarantee the objectives of the European industry\u2019s ecological transition<\/strong>. The project will create the technical basis<\/strong> for a safe and efficient HP segment<\/strong> that will be robust against regulatory uncertainties<\/strong>.<\/p>\n
