Abstract

Ceiling water panel heating - cooling systems. Experimental and simulated study of the performances J.Miriel, L.Serres, S.Pretot Laboratoire de thermique des Bdtiments, Groupe de Recherche en Genie Civil, INSA de Rennes, France Abstract The ceiling water panel technique is mainly used to provide cooling. As for the floor water panel system, it can provide heating in winter and cooling in summer. Ceiling water panels which are incorporated into false ceilings are made of steel or copper pipes with rigid diffusion fins generally in aluminium. The materials used present a good thermal conductivity and a low thermal inertia. The water panels diffuse or absorb heat by natural convection and radiation at the same time through the front side towards the room and through the backside towards the plenum. The diffusion fins being separated, there is a re - circulating air flow between these two zones (room and plenum) which also participates in thermal exchanges. In order to get a bette
