A thermal system for a facility includes a facility fluid circuit, a ground-source heat pump, and an air-source heat pump. The ground-source heat pump and the air-source heat pump each include a fluid circuit connected to the facility fluid circuit in parallel via a common facility heat exchanger. The ground-source heat pump includes a ground-source heat exchanger for transferring heat between a ground-source working fluid and a downhole fluid of a downhole fluid circuit. The air-source heat pump includes an air-source heat exchanger for transferring heat between an air-source working fluid and an ambient air. Heat can be transferred, at the facility heat exchanger, between the facility fluid and one or more of the ground-source working fluid or the air-source working fluid in order to provide thermal heating, cooling, or both to the facility.

Dual source heat pump system

A thermal system includes a borehole heat exchanger, a facility, a data center including at least one heat generating electronic component, and a ground-source heat pump. A dynamic downhole fluid circuit connects the data center, the borehole heat exchanger, and the ground-source heat pump with a flow of a downhole fluid and is configured to connect the data center, the borehole heat exchanger, and the ground-source heat pump in a plurality of different configurations to reject heat from the data center. The thermal system further includes a facility fluid circuit for connecting the facility and the ground-source heat pump with a facility fluid, wherein the ground-source heat pump thermally connects the dynamic downhole fluid circuit and the facility fluid circuit.

Ground-source thermal system for rejecting data center waste heat to a facility

A thermal system for providing thermal conditioning to a facility includes a facility air circuit for circulating a facility air throughout the facility and a downhole fluid circuit for circulating a downhole fluid. The facility air circuit is thermally connected to a heat pump for exchanging heat with the facility air. The downhole fluid circuit includes the heat pump for exchanging heat with the downhole fluid, a main loop, including a borehole heat exchanger (BHE) for exchanging heat between the downhole fluid and a geological formation, and an exhaust loop including an exhaust heat exchanger coupled to an exhaust of the facility air circuit, wherein the exhaust loop is configured to circulate at least some of the downhole fluid through the exhaust heat exchanger to exchange heat between the downhole fluid and an exhaust flow of the facility air exhausted from the facility at the exhaust.
