12. Nov 2009 - PCM research conference in Karlsruhe

Abstract

More than 130 experts from research and practice met on 10-11 November to discuss the potential applications for phase change materials (PCM) in construction products and building services technology. Office environments can be improved through the use of PCM as temperature peaks can be successfully cut without the need for costly air-conditioning.

more details

This symposium in Karlsruhe demonstrated how there is constant interplay between research, development and application. The presentations and discussions focussed in particular on newly developed PCM systems for passive room cooling and for the reduction of temperature and cooling load peaks, and on experiences with their use in public buildings and offices. The presented projects are part of the EnOB research initiative, which supports the market launch of these systems through product developments, installation of equipment in demonstration buildings as well as evaluation and accompanying scientific research.

Salt hydrates and paraffins can make a very effective contribution to improving the indoor environment in lightweight structures by supporting active air-conditioning or even replacing it. Micro or macro-encapsulated PCM, e.g. in cooling ceilings, are therefore of great interest for use in lightweight steel buildings. If higher-capacity cooling ceilings are used, water-carrying systems such as capillary tube mats can replace simple overnight cooling or rear ventilation. The use of borehole heat exchangers suggests itself here. Systems for combined power, heat and cooling can be made smaller if they are combined with PCM cooling ceilings. During the day, the PCM supports the chiller. At night this regenerates the PCM material.

New BINE Themeninfo

The new BINE Themeninfo on latent heat storage in buildings was also published in time for the symposium. It documents the state-of-the-art in research and construction practice in a compact form.
