文摘
- •
A methodology is proposed to optimise the operating conditions of multilevel refrigeration cycles.
- •
Variables considered for the optimisation include the rotational speed of centrifugal compressors.
- •
Physical limitations of centrifugal compressors (surge and choke limits) are taken into consideration.
- •
The optimisation methodology uses a global optimisation algorithm to explore the solution space.
- •
Shaft work savings of 3% are found.
