Abstract: A heat pump system is configured to have a defrost cycle operable during a heating mode of operation. The system uses: larger than conventionally sized capillary tubes at the liquid refrigerant entry end of an exterior air-source heat exchanger; a special amount of additional refrigerant charge; a supplemental hot gas refrigerant transport line extending from the compressor; a special valve in the new supplemental hot gas refrigerant transport line; and another special valve controlling a restriction to the refrigerant flow in the common consolidated vapor refrigerant transport line exiting the exterior heat exchanger. A controller opens the valve in the new supplemental hot gas refrigerant transport line and to simultaneously engages, for a special period of time, the valve controlling the specially sized restriction to the refrigerant flow in the common consolidated vapor refrigerant transport line exiting the exterior heat exchanger at periodic intervals during potential frost conditions.

Abstract: A direct exchange heating/cooling system includes a specially designed supplemental air-source heat exchanger (also referred to herein as a High Level Heat Dissipater (“HLHD”). The HLHD is coupled to the primary vapor/hot gas line exiting the system's compressor at a point between the compressor unit and the sub-surface geothermal heat exchange tubing, and is operable only in the cooling mode of system operation. The HLHD includes heat exchange tubing that is sheltered from rain/moisture and has supply and discharge refrigerant transport tubing with relatively equally sized interior diameters, designed solely for mostly vapor (as opposed to liquid) refrigerant transport. The HLHD incorporates at least two check valves, or the like, so as to force hot compressor discharge gas through the HLHD in the cooling mode, and so as to prohibit geothermally warmed refrigerant gas flow through the HLHD in the heating mode. The HLHD has specially designed heat exchangers and may optionally include a fan.

Abstract: A direct exchange geothermal heating/cooling system has a self-adjusting expansion valve and a bypass flow path to improve efficiency when the system operates in a heating mode. The expansion valve may operate based solely on pressure from the vapor refrigerant transport line. The system may alternatively include an accumulator, a compressor, and an oil separator, wherein an oil return line returns oil from the oil separator to the accumulator. Additionally, a direct exchange geothermal heating/cooling system may include a hot-gas bypass valve for diverting heated vapor refrigerant to the liquid refrigerant line. Finally, a direct exchange geothermal heating/cooling system having a sub-surface heat exchanger extending to a depth of at least 300 feet may use a refrigerant particularly suited for such an application.
