Abstract

A ground source heat pump device and system includes a supply line for removing groundwater from an underground water source, a return line for returning the groundwater to the underground water source, and a heat pump that is able to utilize the supplied groundwater as a medium for transferring thermal energy between the groundwater and a refrigerant. In one embodiment, the heat pump can further include a circulation pump for circulating the groundwater through the system, and a vacuum unit for removing air from the system and filling the supply line, return line, heat exchanger and circulation pump with the groundwater.
