[en] The present paper introduces an experimental investigation
of a scroll compressor working with two-phase refrigerant flows, in the
frame of a novel thermodynamic cycle making use of two-phase compressions/
expansions called REGEN-BY-2.
The design of the test bench dedicated to two-phase compression will
first be explained. The objective of this test bench is to assess the performances
of the compressor working with a two-phase refrigerant-oil
mixture (R1233zd(E) – Emkarate RL32 MAF) under varying conditions
such as inlet pressures, inlet vapor qualities, oil circulation ratio, pressure
ratios and speeds. In order to investigate losses that could come from an
unperfect compression, the pressure ratio can be manipulated to reach
over and under compression. The vapor quality can go down to 35% in
mass fraction. Finally, the post-processing methodology is detailed and
the results of the test bench analyzed, showing the influence of the pressure
ratio, the speed, the vapor qualities and the oil circulation ratio on
the isentropic and volumetric efficiencies.
