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 ...
Experimental analysis of transcritical CO2 booster refrigeration system with heat recovery and ejector expansion
Experimental investigation of CO2 systems for Indian supermarkets with parallel configuration of multiejectors (INDEE)
Modelling and development of high-pressure-lift ejector for low temperature evaporators in R744 refrigeration systems for supermarkets
Experimental Evaluation of a Multi-Ejector Trans-critical CO2 System for Supermarkets
CO2 units for supermarkets and efficient integration
Experimental study of the heat transfer problem in expansion devices in CO2 refrigeration systems
Two expansion devices designed for CO2 refrigeration systems namely, capillary tube and fixed-geometry ejector were experimentally tested in the SINTEF/NTNU laboratory in Trondheim, Norway to determine the influence of ambient conditions on their performance. The novelty of this research was to exam...
