Expérience avec des plafonds refroidis LowEX à matériau à changement de phase dans les immeubles pilotes.

Experiences with LowEX PCM chilled ceilings in demonstration buildings.

Résumé

In several demonstration and commercial projects new chilled ceilings with integrated PCM as dispensed latent heat storage were installed for high efficient low exergy cooling in buildings. Different combinations of ceilings and cold sources were realized to show the main advantages of using PCMs for each combination. The aim of the research project was to develop new technologies to reduce the primary energy needs for cooling in buildings and to create the possibility to cover this energy demand with environmental heat or cold sources. Decoupling the cooling demand from the cold production and adding thermal mass to a construction material are the best approaches for this target. Both allows to shift the cold production from day to night, where most cold sources work more efficient due to lower night air temperatures. LowEx cooling concepts especially with low power or expensive cold sources, for example borehole heat exchangers, often need storage capacity to be able to cover the cold demand.
