Abstract
A heat exchange system with a glycol/water loop to exchange heat with ambient air, and a second glycol/water loop that is in a heat exchange relationship to the ground and a system of refrigerant based ground source heat pump (GSHP) systems. This provides an additional source of cooling or heating in lieu of the ground loop when ambient conditions dictate its use. An additional air/liquid heat exchanger is employed to exchange energy between the ambient air and the water/glycol mixture used in the conventional GSHP installation. Various sensors, one (or more) controller(s) and valves are employed to bypass the conventional ground source heat exchangers.
