Summary

The interest in two stage cycles has increased in the last years and some compressor manufacturers have commercialized
compressors adapted to work in these conditions. Nevertheless, the information supplied by them usually is limited to certain
design conditions defined by the application and extrapolation to other conditions is not straight-forward. In this article a test
campaign of an injection scroll compressor is presented. This test campaign was divided in two parts, on the first one a wide range
of evaporating and condensing pressures for the intermediate conditions recommended by the manufacturer were measured. and the compressor behavior was systematically compared with single stage compressor of the same volume. On the second part an experimental study of the influence of the intermediate conditions on the performance have been done. The study has included the evaluation of the separate influence of intermediate gas superheat, intermediate pressure and wet injection.
