Abstract:
The CYCLE_D package simulates vapor compression
refrigeration cycles that use pure refrigerants or
mixtures of refrigerants. The model can simulate a basic
subcritical or transcritical refrigeration cycle, both
with or without a liquid-line/suction-line heat
exchanger. In addition, the model can simulate a
subcritical two-stage economizer cycle, a subcritical
three-stage economizer cycle, and a subcritical
two-stage compression cycle withintercooling. CYCLE_D
operates in a user-friendly Microsoft Windows
environment that facilitates evaluating the performance
of selected working fluids at different operating
conditions. Calculations are based on refrigerant
properties as represented in the NIST Reference Fluid
Thermodynamic and Transport Properties Program -
