The renewable energy supply of buildings is indispensable for a successful energy transition from reliance on grid supply to locally produced energy. Hence, modern building technology concepts should be designed to generate most of the energy for heating, cooling and electricity locally from renewable energy sources. The main objective of the TRI-HP project is the development and demonstration of flexible, energy efficient and affordable tri-generation systems (tri stands for heating, cooling and electricity).
The systems will be based on electrically driven natural refrigerant heat pumps coupled with renewable electricity generators (photovoltaics/PV), using cold (ice slurry), heat and electricity storages to provide heating, cooling and electricity to multi-family residential buildings with an on-site renewable share of 80%. The project will develop two system concepts for two different combinations of heat sources.
DTI contributes as work package leaders, tasked with the development and testing of icephobic surfaces that lower the freezing point of water and reduce the adhesion of the ice formation. This increases efficiency and ensures a stable operation throughout the entire cooling system life.
