摘要： A centrifugal compressor for a chiller includes a casing, an inlet guide vane, an impeller downstream of the inlet guide vane, a motor and a diffuser. The casing has inlet and outlet portions with the inlet guide vane disposed in the inlet portion. The impeller is rotatable about a rotation axis defining an axial direction. The motor rotates the impeller. The diffuser is disposed in the outlet portion downstream from the impeller with an outlet port of the outlet portion being disposed between the impeller and the diffuser. A hot gas injection passage is provided to inject hot gas refrigerant between the inlet guide vane and the impeller. A controller is programmed to control an amount of the hot gas refrigerant.

摘要： An engine assembly includes a compressor section configured to supply compressed air and a combustion section coupled to the compressor section. The compressor section includes a diffuser with diffuser vanes to condition the compressed air, and the diffuser vanes have a vane count of a first value. The combustion section includes a combustion chamber to receive the compressed air and fuel injection assemblies configured to introduce fuel into the combustion chamber. The fuel injection assemblies have a fuel injection assembly count of a second value, and the first value is a whole number multiple of the second value.

摘要： Die Erfindung betrifft eine Rückführstufe (RCH) einer Radialturbomaschine (RTM) mit mindestens einer Leitschaufelstufe (VST), wobei die Rückführstufe (RCH) sich ringförmig um eine Achse (X) erstreckt, wobei die Rückführstufe (RCH) nach radial innen von einer inneren Grenzkontur (IDC) und nach radial außen von einer äußeren Grenzkontur (ODC) definiert ist, wobei die Leitschaufelstufe (VST) Leitschaufeln (VNS) umfasst, dessen umströmten Oberflächen (SFC) sich von einer stromaufwärts befindlichen Eintrittskante (LDE) als eine Druckseite (PRS) und als eine Saugseite (PCS) entlang einer Skelettlinie (SCL) voneinander beabstandet um Profilquerschnitte (PRC) bis zu einer Austrittskante (TLE) erstrecken, wobei eine Tangente an der Skelettlinie (SCL) eines jeden Profilquerschnitts (PRC) zu einer radial-axialen Referenzebene (PRF) einen Schaufelkonstruktionswinkel (CVA) für jeden Punkt der Skelettlinie (SCL) einschließt, wobei eine Differenz zwischen einem Schaufelkonstruktionswinkel (VCA) an der Eintrittskante (LDE) und einem Schaufelkonstruktionswinkel (VCA) an einer stromabwärtigen Position einen Umlenkungswinkel (RDA) für jeden Punkt der Skelettlinie (SCL) eines jeden Profilquerschnitts (PRC) definiert, wobei die Leitschaufeln (VNS) sich zumindest entlang eines Teils des dritten Abschnitts (SG3) erstrecken, wobei die Austrittskanten (TLE) im dritten Abschnitt (SG3) angeordnet sind, dadurch gekennzeichnet, dass an den Austrittskanten (TLE) in der Mitte der Spannweite (SPW) der Umlenkungswinkel (RDA) jeweils größer ist als der mittlere Gesamtumlenkungswinkel (RAM), wobei an den beiden Enden der Spannweite (SPW) zu jeweils mindestens 10% der Spannweite jeweils der Umlenkungswinkel (RDA) kleiner ist als der mittlere Gesamtumlenkungswinkel (RAM).

摘要： A motor includes a rotor including a rotary shaft that extends in the vertical direction, a stator (1) that faces the rotor (2), a bearing (41, 42) for supporting the rotary shaft for rotation, a bearing holder (4) for holding the bearing, a bracket (5) for holding the bearing holder, and a circuit board (7) having electronic components mounted thereon. The electronic components include a converter, an inverter, and a detection unit. The detection unit detects the rotation angle of the rotor on the basis of an induced voltage generated in the stator due to rotation of the rotor. The bracket (5) includes a holding member that holds the lower end of the bearing holder (4). The circuit board (7) is disposed under the holding member in the axial direction. The electronic components are disposed on the lower surface of the circuit board (7).
