What's inside?
The project involves the design of a 2-stage centrifugal compressor for an updated range of chillers which is expected to operate using the new medium pressure, low GWP refrigerant R1234ZE. The client asked ADT to perform a meanline analysis and the detailed design of 2 compressor stages, including impeller, vaneless diffuser and volute.
The performance of the volute was verified by CFD analysis together with the impeller and vaneless diffuser at various flow rate conditions. No reverse flow was observed at the lowest RPM and flow rate. Both the two stages’ performance showed good efficiency and operational range.
In this consultancy summary, you will:
- Discover how the full power of TURBOdesign Suite was utilized to meet challenging requirements on efficiency and a wide operating map.
- Understand how the design met targets of four rating conditions, a maximum lift condition and by keeping the maximum choking capacity within limits set by the customer.
- See how the volute was designed to match well with the vaneless diffuser exit velocities.
