What's inside?
The project involves the design of a two-stage centrifugal compressor for chiller application. The refrigerant adopted is R1224yd(Z), which is a non-flammable (ASHRAE A1), low pressure, low GWP (under 1) refrigerant newly developed for chiller and heat pump applications. The capacity requirements include three operating modes: frequent operation, over load and low load operation. The compressor design aims to cover these operating points with different pressure ratio and under different massflow rate.
The final design of the two stage compressor stage using the low GWP refrigerant met the targets on high COP at frequent operating points while meeting the high and low load requirements.
In this consultancy summary, you will:
- Discover the design techniques to achieve the design of two stage back-to-back compressor that meets the requirements.
- Understand why a back-to-back configuration has been selected in this project.
- Find out how the full TURBOdesign Suite package worked together to create the design.
