Analyse des échangeurs de chaleur enterrés pour les pompes à chaleur géothermiques dans les maisons individuelles anciennes.

Analysis of ground heat exchangers for geothermal heat pumps in old individual houses.

Auteurs : CAURET O., DALICIEUX P.

Résumé

In most European countries, ground source heat pumps (GSHP) are installed mainly in new houses. The main barriers for installation of GSHP on retrofit market are linked to the installation process and costs of ground heat exchangers. This study evaluates the impact and sizing of two types of ground collectors, potential best solutions for retrofit market, partly by using a specific GSHP modelling tool. This leads to the determination of a ground collectors system adapted to the retrofit market, consisting in 50 meters depth borehole heat exchangers. In a second part, the paper presents an analysis of solar ground reloading influence on GSHP sizing, global performances and costs, using the same modelling tool. In conclusion, this paper shows that 50 meters depth borehole heat exchangers associated with solar ground reloading system is an interesting technological solution, but doesn't always meet retrofit market requirements in term of compacity and costs.
