GeoExchange
Geo exchange refers to heating and cooling systems that use the ground as a heat storage medium. Most geo-exchange systems use heat pumps to move heat between the ground and the building. In the summer, when a room within the building requires cooling, the heat pump takes heat from the room and stores it in the ground. In the winter, the heat pump reverses so that it can take the heat stored in the ground and deliver it to the building. Most geo exchange systems use a network of vertical boreholes with antifreeze circulating from the heat pumps to the boreholes.
