Performance operation of liquid ejectors for a R744 integrated multi-ejector supermarket system using a hybrid ROM
Performance maps were generated for designed liquid ejectors installed in a multi-ejector module in an R744 integrated supermarket system using a hybrid of the reduced-order model (ROM). Hybrid ROMs of the investigated liquid ejectors were developed based on experimental data and CFD results. The CF...
Experimental and computational analysis of a R744 flashing ejector
Not-in-kind approach to remote monitoring in CO2 refrigeration systems
The complexity of CO2 layouts for commercial refrigeration installed in warm climates, integrating also air conditioning and heating, with different load ratios, poses challenges in evaluating and comparing energy performances. Both analysis based on first or second law of thermodynamics requires th...
Dynamic modelling of a refrigerated cabinet with integrated phase change material thermal storage
Thermal storage can help to maintain constant temperature in a refrigerated cabinet during defrost cycles or power outage. This contributes to reduced loss in product quality and hence less food being wasted. Dynamic modelling was applied to study the benefits of integrating phase change material (P...
CO2 ejector modelling using CFD: current status
This paper presents the current status of CFD modelling applied to CO2 two-phase ejectors for refrigeration applications. Previous reviews on CO2 ejector technology have provided detailed analysis and thorough discussion about the optimal design and performance parameters. However, there is still a ...
