Development of semi-hermetic CO2-compressors.

Author(s) : NEKSÅ P., DORIN F., REKSTAD H., et al.

Summary

A semi-hermetic CO2 compressor series in the range of 1.7-10.7 m3/h swept volume has been developed. The series comprises single- and two-stage compressors with two cylinders, running at nominal speeds of 1450 and 2900 rpm (50 Hz). This corresponds to cooling capacities in the range of 3-25 kW at -10 °C evaporating temperature. Measurements of compressor efficiencies are presented for a single- and a two-stage compressor in the lower capacity range of the compressor series. The loss distribution in the single-stage compressor at the present stage of development is analysed and discussed.
