In the heat pump 100 provided in this embodiment, when assembling, the fan 121 side components are first mounted on the first assembling module 150 in sequence, the water module components are mounted on the second assembling module 160, then the first chassis 1141 of the first assembling module 150 is placed on the base 170 and is connected with the base 170, and the second chassis 1142 of the second assembling module 160 is placed on the base 170 and is connected with the base 170 and the first chassis 1141. Finally, the top cover is arranged on the first assembly module 150 and the second assembly module 160, and the assembly of the heat pump 100 can be completed.

In summary, the heat pump 100 provided in this embodiment has a simple and compact water module pipeline structure, and can accurately monitor water flow conditions.

In addition, the present embodiment further provides a water system, where the water system includes a water pipeline and the heat pump 100, and a water module pipeline of the heat pump 100 is connected to the water pipeline to form a circulation waterway. The water pipeline can be a floor heating pipeline, a shower pipeline and the like.

Therefore, the water system provided by the embodiment has a simple and compact structure, and can accurately monitor the water flow condition.

Although the present utility model is disclosed above, the present utility model is not limited thereto. Various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the utility model, and the scope of the utility model should be assessed accordingly to that of the appended claims.
