Abstract
The present invention discloses groundwater heat transfer system comprising a primary pump suspended in a well and connected to at least one water supply pipe, a heat exchange system being connected to said primary pump via a secondary pump, a return pipe being connected to the heat exchange system and returning water from the heat exchange system to the well, wherein the primary pump provides motive pressure to a primary nozzle of a liquid jet ejector submerged in the well, which entrains filtered groundwater through a secondary nozzle of the liquid jet ejector, wherein the secondary pump, placed after the primary pump and before the heat exchange system, provides the remaining system head.
Claims5
An open-looped groundwater heat transfer system for standing column groundwater heat pump applications, said system comprises:
- a primary pump, said primary pump is connected to at least one water supply pipe, said at least one water supply pipe extending downhole to a bottom of a well,
- a heat exchange system, said heat exchange system being connected to said primary pump via a secondary pump,
- a return pipe, said return pipe being connected to said heat exchange system and returning water from said heat exchange system to said well,
- wherein the primary pump provides motive pressure to a primary nozzle of a liquid jet ejector submerged in the well, which entrains filtered groundwater through a secondary nozzle of the liquid jet ejector, and
- wherein the secondary pump, placed after the primary pump and before the heat exchange system, provides a remaining system head.
