Influence of the piston displacement profile on the performance of a refrigerating cycle equipped with an axial piston compressor

- An axial piston compressor working with R134a is studied numerically.
- The influence of the displacement profile on the performance is estimated.
- The absorbed power depends on the displacement profile at the discharge phase.
- A COP variation of 20% is estimated by changing the displacement profile.
- The mechanical stresses are strongly influenced by the in-cylinder pressure.
