✦ Synopsis

Subsoil heat exchangers have the potential to improve ambient conditions in livestock buildings, especially in piggeries. However, the general characteristics of an optimal installation are not well known.

A three-dimensional non-steady-state heat #ow model was developed in order to simulate the heat transfer between the air circulating in the tubes and the surrounding ground. By combining the results of this heat #ow model with those of an experimental subsoil heat exchanger, it was possible to study the in#uence of various parameters, such as the type of ground and the air speed, as well as the characteristics of the pipes (diameter, length, depth and spacing), on the e$ciency of heat exchange.
