Summary

In the Energy Efficiency Center – the new R&D building of the ZAE Bayern - two different PCM cooling ceiling types are installed and monitored in two office rooms. The ceilings are connected to a water circuit and can be used for heating or cooling. The PCM ceilings are prototypes which differ in the positioning of the PCM layer: ceiling type 1 with the PCM on top of and ceiling type 2 with the PCM below the water pipes. It was found, that cooling ceiling type 2 had a better thermal connection between PCM and room, nevertheless, the passive cooling power of the two different system designs was quite similar when measured as a function of the room globe temperature. Passive cooling powers of 10 to 15 W per m² PCM cooling ceiling area were measured for an operative room temperature of 26 °C.
