    • The present application provides a heat pump system. The heat pump system comprises a main circulating refrigerant loop, an auxiliary circulating refrigerant loop, and a refrigerant management system; the main circulating refrigerant loop comprises a main compressor, a first main heat exchanger, a main throttling device, and a second main heat exchanger, the main compressor is configured to allow a refrigerant in the main circulating refrigerant loop to circulate in a main circulating refrigeration working condition flow direction or circulate in a main circulating heating working condition flow direction. The auxiliary circulating refrigerant loop comprises an auxiliary compressor, a first auxiliary heat exchanger, an auxiliary throttling device, and a second auxiliary heat exchanger; the auxiliary compressor is configured to allow a refrigerant in the auxiliary circulating refrigerant loop to circulate in an auxiliary circulating heating working condition flow direction. The refrigerant management system is controllably connected to or disconnected from the main circulating refrigerant loop and the auxiliary circulating refrigerant loop, separately; the refrigerant management system is configured to be capable of distributing a refrigerant used for the main circulating refrigerant loop to the auxiliary circulating refrigerant loop. Less refrigerant is used in the heat pump system provided by the present application.

    • The present application discloses an impeller for a centrifugal fan and a centrifugal fan. The impeller comprises a support member and several vanes. The support member has an inner wall that defines a hollow portion. The several vanes are arranged inside the hollow portion, each of the several vanes is connected with the inner wall and extends along the axial direction of the support member, and the several vanes are arranged along the circumferential direction of the support member. Each of the several vanes is bent and comprises a front edge, a tail edge, a convex suction surface, and a concave pressure surface, the suction surface and the pressure surface are arranged to oppose each other, and the front edge and the tail edge are arranged to oppose each other, wherein the tail edge is connected with the inner wall of the support member, and wherein several protrusions are provided on the suction surface, and the several protrusions are arranged to be close to the front edge. The protrusions can regulate the flow of a fluid immediately when the fluid contacts the vanes. During the flow regulation process, a large vortex in the fluid can be divided into several small vortices. Such small vortices have smaller friction resistance, and the kinetic energy dissipated from the motion of the small vortices themselves can be partially cancelled out, thereby reducing the noise of the impeller and improving the performance of the centrifugal fan.

    • A fan, comprising blades (102), an upper hub (111), and a lower hub (112). Each blade (102) comprises a connecting part (211). The connecting part (211) is clamped between a lower surface of the upper hub (111) and an upper surface of the lower hub (112). The lower surface of the upper hub (111) is provided with an upper hub connecting area, and the upper surface of the lower hub (112) is provided with a lower hub connecting area. An upper surface and a lower surface of the connecting part (211) are separately provided with a junction surface extending from the connecting part (211). The lower surface of the upper hub (111) and the upper surface of the lower hub (112) are separately provided with a matching surface matching the junction surface. The junction surface and the matching surface are arranged in the radial direction and/or circumferential direction of the upper hub (111) and the lower hub (112), and are configured to match with each other to impede the movement of at least two blades (102) in the circumferential direction and/or radial direction with respect to the upper hub (111) and the lower hub (112). The fan structure can prevent the movement of the blades (102) with respect to the upper hub (111) and the lower hub (112). The connecting part (211) and the fan body (201) are not easy to break and can be easily assembled, such that better stability can be ensured while the cost is low.
