ABSTRACT:
A geothermal subcircuit for use with a conventional air conditioning unit. The subcircuit includes a geothermal heat exchanger that is buried in the ground or submerged in a lake, river, well or geothermal heat sink. The geothermal subcircuit is connected with the geothermal heat exchanger in parallel with the outdoor air coil. The control mechanism operates to selectively move refrigerant through the outdoor air coil during the cooling mode or through the geothermal heat exchanger during the heating mode.
