Résumé

This article is the Spanish translation of an article presented at the IIR conference in Karlsruhe, Germany (see the Bulletin of the IIR, reference 2009-1689). 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.
