NUMERICAL ESTIMATION OF MAIN PARAMETERS FoR REALISTIC TWO-STAGE AMMONIA REFRIGERATING SYSTEMS

V K Gupta, Manohar Prasad

Abstract


Two stage ammonia systems, one with a flash intercooler only while the other with a precooler and a flash intercooler, are analysed with the objective function as COP. Correlations of main design parameters, inter-stage pressure and refrigerating efficiency, have been developed and presented for optimum performance. The effect of precooling on system performance is described.

Keywords


Two-stage ammonia systems; refrigerating system; precooling.
