Abstract
An example heat pump system includes a first circuit including a first refrigerant configured to cycle a non-mechanical liquid to high critical vapor fluid phase in a closed circuit from an evaporator to an outlet of a liquid pump and a second circuit comprising a second refrigerant. The second circuit is configured to extract thermal energy from the first circuit to produce a heated fluid and a cooled fluid. The first circuit and the second circuit are configured in a mechanical relationship for transferring energy from the first circuit to the second circuit via a phase change of the first refrigerant through a dual chambered heat pump, the first circuit including a non-mechanical phase liquid to high critical vapor fluid phase.
