Techno-economical analysis of large refrigeration systems - operational and maintenance strategies
This proposed work includes practical analysis of field data of real refrigeration systems and especially the compressor performance.
Background
Large refrigeration systems such as marine HVAC solutions or industrial process refrigeration systems use vast amounts of energy. Even small improvements in system efficiency may have considerable impacts on the cost of operation and not the least on the environmental impact footprint. There are often monitoring systems available, but the practical analysis and interpretation of the actual performance and efficiency may lack.
This proposed work includes practical analysis of field data of real refrigeration systems and especially the compressor performance. One key task the evaluation and techno economic analysis of compressor renovations of large size compressors. Due to the large cooling capacities, the compressor efficiency will have a significant impact on the input power and associated energy.
The target is to find means and measures to evaluate the relevant efficiencies and to determine the techno economic optimum for renovations or other related measures to improve the efficiency and lower the cost of operation and environmental footprint.
The work will include analysing data from field measurements combined with literature studies, experimental work and calculation/modelling. EKA has access to field data where systems can be evaluated from a functional and performance point of view. The consortium behind this thesis task is a cooperation between EKA, Kompressorteknik and KTH.
