Slab cooling and earth coupling.

Author(s) : MEIERHANS R. A.

Summary

The slab cooling system installed in a Swiss office building combines the advantages of radiant cooling with the thermal storage of massive concrete ceilings. The concrete core is cooled by cold water during the night. The water circuit includes a water-air heat exchanger, which cools down the ceiling to 20-22 deg C by means of heat exchange with the cool night air. During the day, the ceiling absorbs the room loads. The heat exchange in the building occurs at a relatively high temperature level (20 to 26 deg C), which allows the use of alternative cooling sources, e.g. earth coupling.
