Patent ID: 7716943

Claim:
A heat pump system comprising: a compressible refrigerant circulating through a first heating/cooling exchange loop including a refrigerant to water heat exchanger to produce a first output; the refrigerant circulating through a second heating/cooling exchange loop including a refrigerant to forced air heat exchanger to produce a second output; the refrigerant flowing through at least one compressor fluidly coupled to the first heating/cooling exchange loop and the second heating/cooling exchange loop; a controller connecting to a plurality of inputs and controlling the speed of the compressor responsive to the plurality of inputs, receiving data from a zone controller, the zone controller including a plurality of zoned thermostat inputs from within a building structure, connected to control the first output and the second output and to transmit control signals to the at least one compressor, for balancing the first output and the second output responsive to a structural heating/cooling load, diverting a portion of the refrigerant from the air heat exchanger to increase the first output; both the refrigerant to water heat exchanger and the refrigerant to forced air heat exchanger are located within the structure; and wherein the temperature and pressure of the refrigerant exiting the water heat exchanger is substantially equal to the temperature and pressure of the refrigerant entering the forced air heat exchanger.
