Foundation heat exchangers (FHX) are an alternative to more costly ground heat exchangers utilized in ground-source heat pump (GSHP) systems serving detached or semi-detached houses. FHX are placed within the excavation made for the basement and foundation along with other excavations used for utility trenching. This seminar describes a model and its validation against experimental measurements in two test houses in Tennessee. In addition, the effects of various US climates on the performance of FHX are reported.
