Effect of thermodynamic parameters on the performance of refrigerator-ejector

Effect of thermodynamic parameters on the performance of refrigerator-ejector Abstract A 3D calculation model of a refrigerator-ejector was built and simulated in a compression/injection hybrid refrigeration cycle system by using the FLUENT software of CFD. The effect of thermodynamic parameters (the pressure of primary fluid and secondary fluid) on the performance of the refrigerator-ejector was studied. The boundary conditions were set according to the actual operating condition and the parameters of refrigerator experimental sample. The numerical calculation results show that there is one optimal pressure of primary fluid, i.e., p popt = 0.06612 MPa, corresponding to the maximum entrainment ratio, i.e., u = 0.568; and there is one optimal pressure of secondary fluid, i.e., p hopt = 0.04837 MPa, corresponding to the maximum entrainment ratio, i.e., u = 0.564. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png "Frontiers in Energy" Springer Journals

Abstract

Abstract A 3D calculation model of a refrigerator-ejector was built and simulated in a compression/injection hybrid refrigeration cycle system by using the FLUENT software of CFD. The effect of thermodynamic parameters (the pressure of primary fluid and secondary fluid) on the performance of the refrigerator-ejector was studied. The boundary conditions were set according to the actual operating condition and the parameters of refrigerator experimental sample. The numerical calculation results show that there is one optimal pressure of primary fluid, i.e., p popt = 0.06612 MPa, corresponding to the maximum entrainment ratio, i.e., u = 0.568; and there is one optimal pressure of secondary fluid, i.e., p hopt = 0.04837 MPa, corresponding to the maximum entrainment ratio, i.e., u = 0.564.
