摘要: An extraction impeller (200) for an axial compressor (102) includes first vanes (210) having an elongated S-shape arranged on the surface (204) of an impeller body (202). The first vanes (210) extend radially from an outer flow inlet edge (220) of the body (202) to a flow outlet hub (222) centered on the surface (204) at the rotation axis (A). A radially inner end (224) of each of the first vanes (210) connects at the flow outlet hub (222) in a direction perpendicular to a rotation axis (A). Second vane(s) (230) are arranged between adjacent first vanes (210), and third vanes (240) are arranged between second vanes (230) and between first vanes (210) and second vanes (230). Second vanes (230) are radially longer than third vanes (240). The impeller (200) extracts air from the axial compressor (102) and forms an axial flow with reduced vortex whistle. When used in an axial compressor (102) of a gas turbine system (100), the impeller (200) reduces flow unsteadiness.

摘要: Disclosed are an axial fan assembly and a motor home air-conditioner using same. The motor home air-conditioner comprises an air-conditioner body (1). A heat exchanging system, a central air-inlet channel (2) and a peripheral air-outlet channel (3) are arranged in the air-conditioner body (1). The heat exchanging system comprises an evaporator assembly (4) distributed in a ring and an axial fan assembly (5) located within the evaporator assembly (4). The axial fan assembly (5) comprises an axial fan (6) and a skeleton-type blast ring (7). The axial fan (6) is mounted within the skeleton-type blast ring (7). The skeleton-type blast ring (7) comprises a drainage pressurized region (71) and an airflow diffusion region (72) for air to flow out. The airflow diffusion region (72) comprises a circumferential air-outlet region (721) and an axial air-outlet region (722). The present axial fan assembly not only meets the requirement of strength in installation, but also changes the direction of airflow blown by the axial fan to achieve the blowing effect of mixed windflows

摘要: A centrifugal ceiling fan adapted to evenly ventilate and heat its surrounding area. The fan comprises a casing defining a top, a side, and a bottom. The air inlet is provided in the top and the air outlet comprises a first passage provided in the side and a second passage provided in the bottom, and a central dome for regulating the flow of air between the first passage and the second passage to a desired proportion. The fan comprises a centrifugal propeller having blades which are curved and have a variable width such that rotation of the centrifugal propeller causes air to be received from said air inlet and to be pushed from said air outlet in substantially all directions between the first direction and the second direction. The dome comprises a heat source for heating air pushed downward from the bottom. Whereby, unheated air is pushed sideways and heated air is pushed downward and for evenly ventilating and heating a room in which the centrifugal ceiling fan is installed.
