and it is seen in Fig. 5(a) that the decreasing rate is similar. Figures 5(b) and (c) show the evaporation temperature and evaporation pressure rise with increasing flowrate of working fluid..., with increasing the working fluid flowrate the evaporation temperature, the evaporation pressure and the outlet temperature of either heat source or cooling source keep stable. However, the decrease......
, and constant pressure heat rejection in a condenser. The working fluid is isentropically compressed in the pump (1-2) and flows into the heat exchangers to take the available energy from the heat source (2-5... temperature and pressure (Tc and Pc) calculated by the GC methods (GCM) and the NIST database for the selected working fluids. The comparison shows that the agreement of Tc is slightly better than Pc......
