Abstract

First, a system for providing liquid refrigerant subcooling, subsequent to that subcooling accomplished by the primary condenser, by means of direct geothermal heat exchange and if required, secondary (or more) fluid(s) supplementary cooling of the liquid refrigerant contiguous with the direct geothermal subcooling. This system could be utilized with standard condensers for higher efficiency air conditioning, heat pump in the cooling mode, or refrigeration operation of any kind. No modifications to the actual condenser would be required, but a larger evaporator surface could be required. 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.
