Abstract
Provided is a multi-stage compressor which includes: a first-stage compressing unit which includes a first compressing element with an impeller and a second compressing element with an impeller, the first and second compressing elements being connected to each other; and a rear-stage compressing unit which includes at least one rear compressing element with an impeller, wherein the rear-stage compressing unit receives a fluid compressed and output from the first-stage compressing unit.
Claims20
A multi-stage compressor comprising:
- a first-stage compressing unit comprising a first compressing element comprising an impeller to receive and compress a first portion of a fluid and a second compressing element comprising an impeller to receive and compress a second portion of the fluid;
- and a rear-stage compressing unit comprising at least one rear compressing element comprising an impeller;
- and a first intercooler disposed between the first-stage compressing unit and the rear-stage compressing unit in a flow direction of the fluid and configured to separately receive the first portion of the fluid from the first compressing element and the second portion of the fluid from the second compressing element and also merge the first and second portions of the fluid into a merged fluid, wherein the rear-stage compressing unit is configured to receive and compress the merged fluid compressed and output from the first-stage compressing unit, and wherein the first-stage compressing unit is configured such that each of the first and second portions of the fluid compressed by the first and second compressing elements, respectively, is not subsequently compressed by the other of the first and second compressing elements before the rear-stage compressing unit receives the merged fluid.
A multi-stage compressor comprising:
- a front-stage compressing unit comprising at least two compressing elements which are configured to receive and compress first and second portions of a fluid and generate pressure using the compressed first and second portions of the fluid, respectively, at a same time;
- at least one cooler configured to separately receive the compressed first and second portions of the fluid output from the at least two compressing elements and lower down temperature of the first and second portions of the fluid and also merge the first and second portions of the fluid into a merged fluid;
- and
- a rear-stage compressing unit comprising at least one compressing element which receives the temperature-lowered merged fluid to generate pressure, the at least one cooler provided between the front-stage compressing unit and the rear-stage compressing unit in a flow direction of the fluid,
- wherein the front-stage compressing unit is configured such that each of the first and second portions of the fluid compressed by the first and second compressing elements, respectively, is not subsequently compressed by the other of the first and second compressing elements before the rear-stage compressing unit receives the temperature-lowered merged fluid.
