摘要：Thermodynamic analyses of transcritical N2O heat pump cycle are carried out based on the optimization of discharge pressure. A simulation code was developed to study the cycle performances for the given design and operating parameters. This code was integrated with the thermodynamic property subroutine ’N2OPROP’ to estimate thermodynamic properties of nitrous oxide in subcritical and supercritical region. Variation trends of optimal parameters for the N2O system are similar to that of a CO2 system. However, the N2O cycle exhibits higher cooling COP, lower compressor pressure ratio and lower discharge pressure.
