Abstract (en)

The present disclosure provides a heat pump system and a control method thereof. The heat pump system according to an embodiment includes: a compressor (4), a first flow path (100), a second flow path (200) and a third flow path (300); wherein the second end (14) of the first flow path (100), the second end (24) of the second flow path (200) and the second end (34) of the third flow path (300) are connected; two of the first end (11) of the first flow path (100), the first end (21) of the second flow path (200) and the first end (31) of the third flow path (300) are connected to the inlet (42) and outlet (41) of the compressor (4) in specific modes through a switching assembly (90), so that the heat pump system can operate in one or more of a cooling mode, a heating mode, a hot water preparing mode, and a cooling heat recovery mode.
