Heat pump system

A heat pump system, comprising:

• a compressor, wherein the compressor comprises a fluid suction port and a fluid discharge port;
• a first heat exchanger, wherein the first heat exchanger is arranged in a first circulation path;
• a second heat exchanger, wherein the second heat exchanger is arranged in a second circulation path;
• a third heat exchanger, wherein the third heat exchanger is arranged in a third circulation path;
• and
• a six-way valve, wherein:
• the first circulation path, the second circulation path, and the third circulation path are parallel paths, a first end of the first circulation path, a first end of the second circulation path, and a first end of the third circulation path are connected to the six-way valve, and are in controllable communication with the fluid suction port and the fluid discharge port of the compressor through the six-way valve,
• a second end of the first circulation path, a second end of the second circulation path, and a second end of the third circulation path are connected to a common path converging point, and
• the six-way valve comprises six ports, wherein one of the six ports is in communication with the fluid discharge port of the compressor, two of the six ports are in communication with the fluid suction port of the compressor, and a remaining three ports of the six ports are respectively in communication with the first end of the first circulation path, the first end of the second circulation path, and the first end of the third circulation path.
