The pump provides the necessary pressure and flow for the organic Rankine cycle (ORC) system. The traditional methods have obvious limitations...
The efficiency of a compression process (ηisen) is evaluated by comparing the work required for isentropic compression (wisen) to that required by the real compression process (wshaft). In addition to the irreversibility of the compression process, the electric motor that runs the compressor has...
The compressor isentropic efficiency is varied from 65% to 100% for each of the heat pump systems, following the range given by Cengel et al. [54] for low to high efficiency compressors. The results indicate that the heat pump COP increases almost linearly with compressor efficiency. The COP...

Simulations of the ideal transcritical heat pump cycles show maxima in the COP at optimalhigh pressures depending on evaporation temperature and gas cooler outlet temperature. The real compressorbehavior has been incorporated by the isentropic efficiency as a function of the pressure ratio. Then ...
