Jungwirth, C A

This patent describes a reverse cycle heating system for a building structure including a compressor acting on a ground heated vaporizable medium, a medium-to-air heat exchanger, means moving an air flow past the heat exchanger, and an expansion valve receiving the medium from the heat exchanger. The improvement described here consists of: a distributor having a multitude of outlets, a collector into which the medium subsequently flows, and a plurality of conduit loops for buried placement, each of the loops being in receiving and discharge communication respectively with the distributor and the collector, the conduit loops extending downwardly in an inclined manner from the distributor and the collector, each of the conduit loops being in a diverging relationship with adjacent conduit loops, each of the conduit loops comprising an inwardly and an outwardly directed parallel tube member adapted for endwise installation within a ground bore, each of the conduit loops being inclined downwardly from a horizontal ground surface at approximately twenty-five to thirty degrees.
