IceEx – Characterization of heat exchanger concepts for ice storages

Ice storages in combination with solar thermal collectors and a heat pump to provide domestic hot water and space heating demands (solar-ice systems) are a promising technology. The project IceEx aims at characterizing heat exchanger concepts for ice storages in solar heating applications. Several heat exchangers, available on the market or recently developed for solar-ice systems, are analyzed by means of experiments and simulations to find an optimum design. Transient yearly simulations are used to assess the system efficiency and energy demand.

This project is financed by the Swiss Federal Office of Energy (SFOE).
