摘要： A heat pump system is provided. The heat pump system comprises a compressor, a first heat exchanger, a second heat exchanger, a third heat exchanger and a six-way valve. The compressor comprises an air suction port and an air discharge port. The first heat exchanger is arranged in a first circulation path, the second heat exchanger is arranged in a second circulation path, and the third heat exchanger is arranged in a third circulation path, 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 air suction port and the air discharge port of the compressor by means of 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. The components of the heat pump system in the present application have simple pipelines, have a high degree of integration, are not difficult to mount, and have a small pressure drop during air suction and discharge, and the control logic therefor is simple.
