CENTRIPETAL DELIVERY COMPRESSOR FOR VENTILATION SYSTEM GENERATING HEAT AT HIGH TEMPERATURE AND HIGH PRESSURE Russian patent published in 2016 - IPC F04D17/02 

FIELD: ventilation.

SUBSTANCE: invention relates to a centripetal delivery compressor for the ventilation system, comprising: a casing, an air inlet in the casing, an air outlet in the casing, an impeller, and a blade drive, at that the layer of centrifugal blades and the layer of centripetal blades are arranged on the inner side of the impeller, the layer of the centrifugal blades and the layer of centripetal blades are staggered at intervals in the axial direction. The centrifugal blades form a centrifugal channel, and the centripetal blades form a centripetal channel. The guide walls for protection of the impeller edges from the air flow are arranged on the outer sides of the centrifugal channel and the centripetal channel, and the reverse channels of the impeller edge are arranged between the guide walls for protection of the impeller edge from the air flow and the centrifugal blades and between the guide walls for protection of the impeller edge from the air flow and the centripetal blades.

EFFECT: obtaining a compressor of simple design, high efficiency, and a wide range of applications, energy saving.
