NIST 49. CYCLE_D: NIST Vapor Compression Cycle Design Program

Published

Author(s)

Joan C. Sauerwein

Abstract

The CYCLE_D database package simulates the vapor compression refrigeration cycles using the 38 pure fluids and mixtures covered by the well-known and widely-used NIST Standard Reference Database 23 - NIST Thermodynamic Properties of Refrigerants and Refrigerant Mixtures (REFPROP).Using the Carnahan-Starling-DeSantis equation of state for all fluids except ammonia, the model can simulate both a reversed Rankine cycle and a cycle with a liquid-line/suction-line heat exchanger. The high-accuracy formulation developed by Haar and Gallagher is used for ammonia.CYCLE_D operates in a user-friendly WindowsTM environment to facilitate evaluating the performance of selected working fluids at different operating conditions.
