Facade integrated latent heat storage system for cooling applications
Latent heat storage systems are a state of the art and well known as ice storages. Typically they are used for compensation of fluctuating cooling loads. New developed paraffin-based latent materials, so called PCMs (phase change materials), can extend the operational area of latent heat storages. PCMs with a melting point near to the room air temperature allow the use of natural heat sinks for cooling applications. The aim of this investigation is to identify the thermal performance of an active latent heat storage system in combination with the ambient air as natural heat sink. The results from the measurements and the accompanying simulations show the thermal performance of an active latent heat storage system for cooling applications by applying the ambient air as natural heat sink. The reduction of the operating room air temperature varied depending on the mass of PCM and the ambient condition. The results show for the test room with a latent heat storage a reduction of indoor air temperature up to 4 K, with a storage mass of 1.7 kg/sqm. This shows the fundamental capabilities of latent heat storages, with a melting temperature near to the room air temperature, for cooling applications. The ongoing investigations should bring further knowledge about the use of latent heat storages in the building sector. For example it is conceivable, to use such type of storage for heating applications.
