Earth-air heat exchangers in the Belgian climate: analysis of the potential with a 3D modelling technique.

Résumé

In this paper a 3 D unstructured finite volume model was derived; it allows evaluation of the earth-air heat exchanger. The model solves conduction through the soil and the convection from air to the tube wall. The air ground-surface heat transfer is described by the heat flux through convection and solar radiation. The model was used to study the performance of the earth-air heat exchanger in the Belgian climate. It was shown that in summer the air can be cooled with about 9°C at sufficient depth (3 m) and tubes of about 50 m. In winter, heating of 7°C can be realised. It was also shown that a good control strategy is important.
