Classification: CPC F  Y | IPC F

Claim 14:
15. The heat pump system of claim 9, wherein in a space heating with desuperheater water heating mode, the controller is configured to control:
the first variable speed pump to enable heat exchange in the desuperheater heat exchanger to heat the domestic water pumped through the desuperheater heat exchanger;
the second variable speed pump to enable heat exchange in the refrigerant-to-liquid source heat exchanger;
the expansion valve and the reversing valve to convey the refrigerant from the first port to the third port and from the fourth port to the second port to cause the refrigerant to:
flow from the desuperheater heat exchanger to the refrigerant-to-air load heat exchanger acting as a condenser; and
return from the refrigerant-to-liquid source heat exchanger acting as an evaporator to the compressor.
