Semi-Theoretical Simulation Model for a Transcritical Carbon Dioxide Mobile A/C System * 2000-01-0985

This paper describes a semi-theoretical simulation model, CYCLE11_CO2, for a transcritical carbon dioxide vapor-compression refrigeration cycle. CYCLE11_CO2 is based on an earlier simulation model, CYCLE11-UA, developed at the National Institutes of Standards and Technology for evaluating alternative refrigerants and refrigerant mixtures. Here we describe CYCLE11_CO2, its inputs, its outputs, and present some typical simulation results. The simulation results are compared to experimental data.
