    Abstract: A climate-control system includes a first working-fluid circuit, a second working-fluid circuit and a first heat exchanger. The first working-fluid circuit includes a first compressor, a second heat exchanger and a first pump. The second heat exchanger is in fluid communication with the first compressor. The first pump receives a first working fluid from the second heat exchanger and circulates the first working fluid through the first working-fluid circuit. The second working-fluid circuit is fluidly isolated from the first working-fluid circuit and includes a second pump and a fourth heat exchanger. The second pump is in fluid communication with the fourth heat exchanger. The first heat exchanger is thermally coupled with the first working-fluid circuit and the second working-fluid circuit.

    Abstract: A system includes a heat-pump circuit and a heating-fluid circuit. The heat-pump circuit includes a compressor and a first condenser conduit. The heating-fluid circuit includes first, second, and third flow-paths. The third flow-path selectively communicates with the first and second flow-paths. The first flow-path includes a first valve. The first valve moves between an open position allowing fluid flow through the first flow-path and a closed position restricting fluid flow through the first flow-path. The second flow-path includes a second condenser conduit and a second valve. When the second valve is open, fluid flows through the second flow-path. In the closed position, the second valve restricts fluid flow through the second flow-path. The third flow-path includes a heat exchanger receiving fluid from the first flow-path when the first valve is in the open position and receiving fluid from the second flow-path when the second valve is in the open position.

    Abstract: A climate-control system may include a working-fluid circuit and a cooling-fluid circuit. The working-fluid circuit may include a compressor, an outdoor heat exchanger, an expansion device, and an indoor heat exchanger. The compressor compresses a working fluid. The outdoor heat exchanger may receive compressed working fluid from the compressor. The expansion device may be disposed downstream of the outdoor heat exchanger. The indoor heat exchanger may be disposed downstream of the expansion device and upstream of the compressor. The cooling-fluid circuit may contain a cooling fluid in a heat transfer relationship with working fluid in the working-fluid circuit. The cooling-fluid circuit may include an underground heat exchanger conduit embedded in earth below an earth ground surface. The underground heat exchanger may selectively receive the cooling fluid such that heat from the cooling fluid is transferred to the earth.
