Abstract
A system for exchanging thermal energy between a fluid medium and the earth is provided employing a number of boreholes drilled vertically in the earth spaced apart by adjacent intervals. An upflow conduit and a downflow conduit are placed in parallel relationship within the boreholes and connected at their lower ends. At the top of each borehole there is a header providing means to conduct fluid through the conduits in each borehole in a parallel or series arrangement. In each of the headers there is a partition dividing the flow of fluid passing downwardly into the borehole from the flow of fluid passing upwardly out of the borehole with a vent in the partition so that air which might otherwise be trapped in the verical conduits can by vented to prevent airlock of the system.
