Two new salthydrate-based phase change materials (PCM) suitable as storage material in chilled ceilings and centralised cold storage systems were developed within the framework of the project PC-Cools_V, The newly developed PCM store cooling energy with a high energy density and at the temperature level needed for air conditioning enabling the required cooling to be provided very efficiently. The PCM melting range is around 21°C (designed for a decentral, room integrated storage application, especially cooling ceilings) and around 15°C (intended for the implementation in central cold storages).
The PC-Cools_V project was funded by the German Federal Ministry for Economic Affairs and Energy as part of the German federal government's Energy Storage research initiative. The project started in December 2012 and completed in January 2017. The aim of this project was to close the gap of available salthydrate-based PCM in the temperature range suitable for building climate control.
