System model derivation of the CO2 two-phase ejector based on the CFD-based reduced-order model
The developed reduced-order model (ROM) of the R744 two-phase ejector was presented in this paper. The proper orthogonal decomposition (POD) model was employed together with the radial basis function (RBF) to evaluate the ejector performance at the motive nozzle operating regime from 70 bar to 100 b...
Novel integrated CO2 vapour compression racks for supermarkets. Thermodynamic analysis of possible system configurations and influence of operational conditions
An increasing number of supermarket chains are opting for the utilisation of centralised carbon dioxide refrigeration systems. However, the need to improve their efficiency in order to make them economically and environmentally sustainable worldwide becomes ever more important. One of the most commo...
