文摘
- •
Correlations based on dimensionless parameters are proposed for compressor efficiencies.
- •
The Buckingham π-theorem was applied to compressor efficiencies.
- •
An energetic comparison between R134a, R1234yf, R450A and R1234ze(E) is developed.
- •
R1234yf, R450A and R1234ze(E) volumetric efficiencies are lower than R134a.
