Claims (1)

  1. Zentrifugalverdichter, umfassend:
    ein Laufrad (2), das über eine Nabe (3) mit einer Drehwelle verbunden ist; und
    einen Diffusor (5), der dem Laufrad (2) nachgelagert bereitgestellt ist, wobei der Diffusor (5) einen Strömungsdurchgang, der sich in eine Richtung weg von der Drehwelle erstreckt, und einen Auslass aufweist, der in eine radiale Richtung in einer meridianen Ebene gerichtet ist, wobei
    der Zentrifugalverdichter θ-α>0° erfüllt
    wo
    θ ein Winkel ist, der durch eine Diffusoreinlass-Nabenseitenlinie (5a) mit der radialen Richtung in der meridianen Ebene an einem Punkt gebildet wird, der einem Auslass (2b) des Laufrads (2) in der Diffusoreinlass-Nabenseitenlinie (5a) am nächsten ist, wobei die Diffusoreinlass-Nabenseitenlinie (5a) eine Linie auf der Seite der Nabe (3) in einem Einlass des Diffusors (5) ist, und
    α ein Winkel ist, der durch eine Berührungslinie (3b) einer Laufrad-Nabenseitenlinie (3a) mit der radialen Richtung in der meridianen Ebene an einem Punkt gebildet wird, der dem Einlass des Diffusors (5) in der Laufrad-Nabenseitenlinie (3a) am nächsten ist, wobei die Laufrad-Nabenseitenlinie (3a) eine Linie auf der Seite der Nabe (3) im Laufrad ist, und dadurch gekennzeichnet, dass
    der Winkel θ so ist, dass 20°<θ<30°, wenn die Diffusoreinlass-Nabenseitenlinie (5a) eine gerade Linie ist, β so ist, dass 0°≤β≤35°, wo β ein Winkel ist, der durch eine Hinterkante (2c) des Laufrads (2) mit einer axialen Richtung gebildet wird.
