Abstract

The earth-to-air heat exchangers, known as Canadian wells, are considered to be a passive air conditioning technique for buildings. They are made of tubes buried underground and for which the coolant is air. The ground high thermal mass can act as a large heat and/or freshness stock and hence can contribute to meet the heating or cooling load of the building. The ground temperature, from some meters depth, varies very little as compared to the room temperature. In summer, the ground temperature is much lower than the air temperature, while in winter, it is much higher. To cool the building in summer, the ventilation flow stream rejects its excess heat in the ground through the buried ground heat exchangers walls before being introduced in the building. In winter, the fresh air flows through the Canadian well ducts and is preheated before being introduced in the building. Within the scope of this work, we have been called to elaborate a mathematical model describing thermal exchanges through the Canadian well. An explicit multi-time-step finite difference numerical model has been developed and coded in FORTRAN language then linked to the TRNSYS computation software. The model has been validated by a short sequence of beforehand established measurements.
