Classification: CPC F | IPC F

Claim 12:
13. A heat pump system, comprising:
a refrigerant circuit comprising a compressor, a reversing valve, a first heat exchanger, a second heat exchanger, a reheat heat exchanger, a three-way valve, and a first flow path and a second flow path arranged in parallel with one another and extending between the second heat exchanger and the first heat exchanger,
wherein the reversing valve is configured to receive refrigerant from the compressor and adjust between a first configuration to direct the refrigerant toward the three-way valve and a second configuration to direct the refrigerant toward the first heat exchanger,
wherein the three-way valve is configured to adjust between a first position to direct the refrigerant between the reversing valve and the second heat exchanger and a second position to direct the refrigerant from the reversing valve to the reheat heat exchanger, and
wherein the first flow path comprises a check valve configured to enable flow of the refrigerant from the second heat exchanger toward the first heat exchanger, and the second flow path comprises a solenoid valve configured to adjust between a third position to direct the refrigerant between the first heat exchanger and the second heat exchanger and a fourth position to block flow of the refrigerant between the first heat exchanger and the second heat exchanger.
