by reducing the consumption of non-renewable primary energy to drive air-conditioning systems for building thermal comfort. The first objective is to develop and produce a solar-powered building cooling system based on climate-friendly refrigerants.The project involves the use of an institutional building that ensures the involvement of one of the main pollution-generating sectors. The COOLSPACES project will demonstrate the technical and economic feasibility of a novel pilot plant with an innovative refrigeration unit that will use refrigerants with minimal greenhouse effect and photovoltaic panels as the main energy source. The goal is to assess the feasibility of adopting the new eco-design in an institutional building located on the campus of Wroclaw University of Technology.

to address the mismatch between renewable energy supply and energy consumption as a strategy to combat climate warming. The goal is to model the behavior of a selected heat storage material in designed refrigeration applications based on solar cells and novel refrigerants.

ensuring a reduction in annual electricity consumption. Activities will involve testing the performance and efficiency of all system components, such as the refrigeration unit, storage tanks, photovoltaic power generation system, as well as smart metering and control solutions. The main focus will be on integrating all these subsystems into an energy autonomous smart system.

in a public facility in Almeria (southern Spain). Once satisfactory results are obtained from the prototype developed at the Wrocław University of Technology, we will study the possibility of applying the device in another geographic location such as the campus of the University of Almeria.
