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. A liquid injection passage is provided to inject liquid refrigerant into an area between the impeller and the diffuser. The motor rotates the impeller. The diffuser is disposed in the outlet portion downstream from the impeller with an outlet port of the liquid injection passage being disposed between the impeller and the diffuser. A controller is programmed to control an amount of the liquid refrigerant injected into the area between the impeller and the diffuser.

摘要： A control device (101) that controls a fuel gas supply system (100) that comprises: a compressor (1) that supplies compressed fuel gas to a load apparatus (15); an inflow amount regulating means (5) that regulates the amount of fuel gas that flows into the compressor (1); and an anti-surge valve (7) that is for returning to an inlet side of the compressor (1) fuel gas that is discharged from the compressor (1). The control device (101) comprises: a main pressure-control unit (101a) that controls the inflow amount regulating means (5) and the anti-surge valve (7) on the basis of a feedforward control value that is generated on the basis of the load of the load apparatus (15) and of a prescribed conversion process, and on the basis of a feedback control value that is generated on the basis of the deviation between a set value and a measured value for the discharge pressure of the compressor (1); and an emergency pressure-control unit (101b) that calculates a bias-added control value that is found by adding a predetermined bias value to an anti-surge valve control value that is for controlling the anti-surge valve (7) and that is calculated on the basis of at least one of the feedforward control value and the feedback control value, and that, on the basis of the occurrence of load variations that are at or above a prescribed value, switches between the anti-surge control value and the bias-added control value and controls the anti-surge valve (7).

摘要： A method for regulating a turbocompressor to prevent surge, is described. The method comprises the following steps: providing at least one surge limit line (SLL) of turbocompressor (21); continuously determining an actual value of a corrected speed (Nc) of the turbocompressor (21); continuously determining at least a maximum admissible pressure ratio (PRmax) on the surge limit line, corresponding to the actual value of the corrected speed; continuously determining an actual pressure ratio (PR); acting upon an antisurge arrangement, if the actual pressure ratio is equal to or higher than the maximum admissible pressure ratio.

摘要： The invention relates to a casing for a turbine engine compressor, comprising: cavities (5) in the thickness of the casing, extending in parallel to one another from the inner face of the casing along a circumference thereof, said cavities not being in communication with one another. The cavities, which are elongate and extend along a main direction of orientation between two side walls, are closed upstream and downstream by upstream and downstream faces respectively, and an upstream border (7) and a downstream border (6) are formed at the intersections between same and the inner face of the casing (4). The casing is characterised in that the upstream border (7) of the cavities (5) takes the form of a wavy line comprising at least two alternate undulations over the length thereof between the aforementioned side walls.

摘要： A supercharger-equipped internal combustion engine in the present invention includes a turbo-supercharger (20) which includes, at some point in an intake passage (26), a centrifugal compressor (20b) having an impeller section (20b4) for housing a compressor impeller (20b3). In the supercharger-equipped internal combustion engine, EGR gas and blow-by gas are introduced into an intake system in such a way as to flow into the centrifugal compressor (20b) via an EGR gas introduction section (40a) and a blow-by gas introduction section (48a). The supercharger-equipped internal combustion engine further includes a partition wall (52) which guides the EGR gas and the blow-by gas toward the centrifugal compressor (20b) so that the EGR gas and the blow-by gas are not mixed with each other until the EGR gas and the blow-by gas enter into the impeller section (20b4).
