NIST Vapor Compression Cycle Design Program : CYCLE_D - SRD 49

CYCLE_D simulates vapor compression refrigeration cycles that use single-compound refrigerants or refrigerant blends. 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 with intercooling. CYCLE_D includes 75 single-compound refrigerants and 113 predefined blends. Single-compound fluids can be combined to form blends of up to ten components. Computationally, the program is fully compatible with the NIST Reference Fluid Thermodynamic and Transport Properties - REFPROP, Version 10.0.
