Water flow control structure and air source heat pump system thereof

The embodiment of the utility model relates to the technical field of thermodynamic systems, and discloses a water flow control structure and an air source heat pump system thereof. The water heater comprises a structure body, and a hot water pipeline penetrates through the structure body to form a first water inlet end and a first water outlet end; the water tank body has a second water inlet end and a second water outlet end; the bypass balance pipe communicates with the hot water pipeline and the water tank body and is used for balancing water flow between the hot water pipeline and the water tank body. And the self-adaptive water pump is arranged on the hot water pipeline. According to the structural design, the advantages of a primary system and a secondary system can be achieved at the same time, meanwhile, the defects of the primary system and the secondary system are avoided to a great extent, and higher energy utilization efficiency and higher system starting speed are achieved. 本实用新型实施例涉及热力系统技术领域，公开
