Description

Technical Field

[0001] The present application relates to the field of air energy heat pumps, and more specifically, to a graphene impeller structure and an air energy heat pump. Background Art

[0002] The air source heat pump is driven by an electric motor and uses the working principle of the vapor compression refrigeration cycle to produce cold (hot) air or (hot) water using ambient air as the cold (hot) source. The main components include hot side heat exchange equipment, heat source side heat exchange equipment and compressor, etc. The outdoor unit of the air source heat pump is prone to frost in winter, which affects the working performance of the outdoor unit of the air source heat pump.

[0003] At present, air energy heat pumps mainly drive the air flow by driving the fan impeller to rotate through a fan, and usually the blades and the hub are an integrated structure. If one blade is damaged, the entire blade must be replaced, which will undoubtedly increase the cost and be wasteful. At the same time, the hub is mounted on the output shaft of the fan and tightened and fixed by nuts. The D-shaped notch design limits the relative rotation of the shaft and the impeller, but it is easy to be twisted into a round hole after long-term use, resulting in loose installation of the impeller or even scrapping.
