Classification: CPC F | IPC F

Claim 0:
1. A method of operating a refrigeration cycle device, comprising:
receiving refrigerant in a first state at a compressor;
compressing the refrigerant in the first state to convert the refrigerant in the first state to refrigerant in a second state;
providing the refrigerant in the second state from the compressor to a water heat exchanger;
desuperheating the refrigerant in the second state in the water heat exchanger such that heat is exchanged between the refrigerant in the second state and water to heat the water and convert the refrigerant in the second state to refrigerant in a third state;
partially condensing the refrigerant in the third state in the water heat exchanger such that heat is exchanged between the refrigerant in the second state and water to heat the water and convert the refrigerant in the third state to refrigerant in a fourth state;
fully closing an expansion valve located between the water heat exchanger and both an indoor air heat exchanger and a first port on an outdoor heat exchanger;
opening a controllable valve between the water heat exchanger and a second port on the outdoor heat exchanger;
providing the refrigerant in the fourth state from the water heat exchanger to the second port of the outdoor air heat exchanger through the open controllable valve;
performing an evaporation operation on the refrigerant in the fourth state in the outdoor air heat exchanger such that heat is exchanged between the refrigerant in the fourth state and outside air located outside a target space to heat the outside air and convert the refrigerant in the fourth state to refrigerant in a fifth state;
expanding the refrigerant in the fifth state from the outdoor air heat exchanger to convert the refrigerant in the fifth state to refrigerant in a sixth state;
providing the refrigerant in the sixth state to the indoor air heat exchanger; and
evaporating the refrigerant in the sixth state in the indoor air heat exchanger such that heat is exchanged between the refrigerant in the sixth state and inside air located inside the target space to cool the inside air and convert the refrigerant in the sixth state to the refrigerant in the first state,
wherein
the first state, the second state, the third state, the fourth state, the fifth state, and the sixth state are all different states of the refrigerant.
