Secondly, a system for providing supplemental heat to the primary evaporator of a heat pump operating in the heating mode, by means of a direct geothermal heat exchange, coupled with heat reclaim of the liquid refrigerant, and if necessary with secondary (or more) fluid(s). This system would require some modification of a standard heat pump in addition to the installation of the direct geothermal liquid refrigerant reclaim, secondary (or more) fluid heat postheater. Next, a system that would provide liquid refrigerant subcooling by means of direct geothermal heat exchange and if required, secondary (or more) fluid(s) supplementary subcooling, coupled with a system that would provide direct geothermal, plus a possible secondary (or more) fluid, supplementary heat, to a postheater of a heat pump in the heating mode. That said postheater becoming a precooler of the hot gas refrigerant when the heat pump is in the cooling mode. Finally, a system that would provide liquid refrigerant subcooling by means of direct geothermal heat exchange and if required, a secondary (or more) fluid(s) supplementary subcooling coupled with a system that would provide direct geothermal heat exchange precooling of the hot gas refrigerant and if required, a secondary (or more) fluid(s) precooling of the hot gas refrigerant. This system could be utilized with standard air source or water source air conditioning or refrigeration condensers for producing more capacity and higher efficiency.

[ now that the invention has been described, what is claimed is:] [1.] A direct geothermal heat exchange refrigerant subcool system comprising in combination:a) a subcooler connected in fluid communication with an output of a condenser of an air conditioner, refrigeration unit, or heat pump enabling a refrigerant to flow through said subcooler;b) a secondary fluid refrigerant subcool system for subcooling the refrigerant that had previously passed through the condenser including at least one secondary tube thermally connected to a tube carrying the liquid refrigerant;c) said subcooler and secondary thermally connected tubes being buried in the ground for direct geothermal heat exchange between the refrigerant and the earth; andd) means for controlling the rate of flow of fluid through said secondary tube for purposes of additional auxiliary sub-cooling or for purposes of preventing geothermal saturation, to provide the maximum available subcooling of the liquid refrigerant.
