Well known in the North of Europe, the water ceiling panel systems are mainly used to provide cooling. However, as well as for a radiant floor, this system can be used for heating in winter and cooling in summer. In order to get a better knowledge of the energy performances of such devices, the Gaz de France Research Centre funded a test campaign during two winters and one summer. This experimental study was carried out in our laboratory, located in Rennes, in western France. A water ceiling panel system and a monitory data acquisition system were installed in a test room. The studied ceiling panel system was made of copper pipes with rigid aluminum diffusion fins. The used materials presented a good heating conductivity and the ceiling radiant panel was fast-acting. Simulation models were developed with the simulation program TRNSYS, using the experimental study results for the code verification.
