General Role: Project acquisition, technical and administrative management of the overall project.
Specific technologies in charge of: Development of ice slurry technology with supercooling method. Dynamic system Simulations TRNSYS. First version of pytrnsys developed.
Main goal of the project: Developing systems based on electrically-driven natural refrigerant heat pumps coupled with photovoltaic to provide heating, cooling and electricity to multi-family buildings with an on-site renewable share of 80 % reducing the installation cost by 10 -15 %.
Extended Summary: The TRI-HP project developed and demonstrated flexible, energy-efficient, and affordable tri-generation systems (heating, cooling, and electricity) for multi-family buildings. These systems used natural refrigerant heat pumps powered by photovoltaics and integrated advanced controls for optimal performance and reliability. Flexibility was achieved through three heat sources: solar (with ice/water storage), ground, and ambient air. The innovations reduced system costs by 10 – 15 % compared to conventional heat pumps.
The systems, using low-GWP refrigerants (propane and CO2), reduced GHG emissions by 75 % compared to gas boilers and air chillers. TRI-HP systems are designed for both new and retrofitted buildings across Europe, addressing stakeholder needs, regulatory standards, and social barriers. Three complete systems (CO2-ice, propane-ice, propane-dual) were developed and tested.
