ABSTRACT = {The performances of a refrigeration unit relying on compressors working in parallel have been investigated considering the influence of the compressor
volumetric efficiency and isentropic efficiency on the compression ratio. Moreover, the following influential factors have been taken into account: evaporation
temperature, condensation temperature and compressor suction-exhaust pressure
ratio for different opening conditions of the compressor. The following quantities
have been selected as the unit performance measurement indicators: refrigeration
capacity, energy efficiency ratio (COP), compressor power consumption, and
refrigerant flow rate. The experimental results indicate that the system refrigeration capacity and COP decrease with a decrease in evaporation temperature,
increase of condensation temperature, and increase in pressure ratio. The refrigerant flow rate increases with the increase in evaporation temperature, decrease in
condensing temperature and increase in pressure ratio. The compressor power
consumption increases with the increase in condensing temperature and increase
in pressure ratio, but is not significantly affected by the evaporation temperature.},
