A pitless adapter includes a casing having first, second and third ports, and a spool having a top plate, a bottom plate having first, second and third ports, a first middle plate between the top and bottom plates and a second middle plate between the first middle plate and the bottom plate. The casing, the top plate and the first middle plate define a first chamber that is open to the first port of the casing and the first port of the spool. The casing, the first middle plate and the second middle plate define a second chamber that is open to the second port of the casing and the second port of the spool. The casing, the second middle plate and the bottom plate define a third chamber that is open to the third port of the casing and the third port of the spool.
A groundwater heat exchanger includes a distributor, a collector, a plurality of heat exchange pipes, and a housing. The distributor includes a first interior chamber and a first port. The collector includes a second interior chamber and a second port. Each heat exchange pipe includes a first end attached to the distributor and a second end attached to the collector, and defines a fluid passageway between the first and second interior chambers. The housing surrounds the heat exchange pipes and defines a groundwater passageway along the heat exchange pipes that is configured to receive a groundwater flow. In one example, a loop fluid flow received at the first port flows into the first interior chamber, then flows from the first interior chamber to the second interior chamber through the plurality of heat exchange pipes, and flows from the second interior chamber out the second port.

A groundwater heat exchange system (100) for regulating a temperature of a loop fluid flow (112) pumped through a closed loop fluid pathway (104) for use by a heat pump (118) includes one or more groundwater heat exchange units (101) and a controller (150). Each groundwater heat exchange unit includes a heat exchanger (102) and at least one groundwater pump (136). The heat exchanger (102) is submersed in groundwater (110) within a borehole (106) and is configured to facilitate heat exchange between the groundwater and the loop fluid flow. Each groundwater pump has a plurality of non-zero flow rate settings corresponding to different non-zero flow rates at which the groundwater pump drives a flow of the groundwater (138) through the heat exchanger. The controller is configured to adjust the flow rate settings of the at least one groundwater pump based on a heat exchange demand input.

SPOOL-TYPE PITLESS ADAPTER FOR GROUNDWATER HEAT EXCHANGER
A pitless adapter (130) includes a casing (132) and a spool (134), which is removably received within an interior cavity (136) of the casing. The casing includes a first port (138A) and a second port (138B). The spool includes a top plate (160A), a bottom plate (160C) having first and second ports (140A and 140B), and a middle plate (160B) between the top and bottom plates. The casing, the top plate and the middle plate define a first chamber (150A) that is open to the first port of the casing and the first port of the spool. The casing, the middle plate and the bottom plate define a second chamber (150B) that is open to the second port of the casing and the second port of the spool. A first fluid pathway (164A) extends from the first port of the spool to the first chamber. A second fluid pathway (164B) extends from the second port of the spool to the second chamber.

A groundwater heat exchanger (102) includes a distributor (140), a collector (144), a plurality of heat exchange pipes (134), and a housing (180). The distributor includes a first interior chamber (142) and a first port (130). The collector includes a second interior chamber (146) and a second port (132). Each heat exchange pipe includes a first end (141) attached to the distributor and a second end (143) attached to the collector, and defines a fluid passageway between the first and second interior chambers. The housing surrounds the heat exchange pipes and defines a groundwater passageway along the heat exchange pipes that is configured to receive a groundwater flow (138). In one example, a loop fluid flow (112) received at the first port flows into the first interior chamber, then flows from the first interior chamber to the second interior chamber through the plurality of heat exchange pipes, and flows from the second interior chamber out the second port.
