Résumé

This paper deals with the roots compressor, which is a rotary machine used for compressing air or refrigerant. It proposes an original way of describing the geometry of the three-lobe compressor in which the symmetries are exploited in order to establish the analytical expressions of volumes and leakages as a function of the orbiting angle. This approach allows the volumes and leakages to be described analytically without any special assumption. Based on the geometrical model, a thermodynamic model is built to predict pressures, temperatures of the different compressor chambers and massflows through the leakages between the chambers and at the compressor outlet and inlet. The simulation and experimentation results show that the model is able to predict these state variables but also the mechanical power and torque on the compressor shaft.
