A Screening of Low-GWP Refrigerant for Ejector Refrigeration
Chemical Engineering Transactions, 2018 Ejector refrigeration is a promising technology to reduce primary energy consumption for building cooling. Unfortunately, a change in the design criteria (i.e., geometry, working fluid, operating conditions) influences the system performance owing to variations in the local fluid dynamic phenomena at the “local-scale”.
