Optimization of energy/performance in the cooling chain using cold physical exergy of cryogens

This work of research is dedicated to optimization of energy in the cooling chain using cold physical exergy of cryogens. Considering the state-of-the-art TRUs and possibility of adopting more sustainable solutions, it was decided to perform a Well-to-Wheel analysis on most probable scenarios for transition in transport refrigeration industry.As far as the author is concerned, Well-to-Wheel analysis on transport refrigeration is not available in the literature so as a starting step for evaluation this technology it was decided to perform this study. Considering the low cost of ownership and relatively low emissions for cooling based on physical exergy of cryogens, system modeling and optimization of cryogenic based cooling was done. 2nd law analysis was performed for spotting components with largest entropy generation and finally measured proposed to enhance the performance of the system and minimize the losses. Use of Hydrogen(liquid or compressed form) for providing cooling using its physical exergy has not mentioned in literature. Second law analysis and well-to-wheel analysis were done for the first time on cooling system based on physical exergy of air, oxygen and hydrogen as cryogen. Techno-economic study for PV-based cooling in transport refrigeration is done as a possible solution decreasing the dependence on fossil fuel specially for warmer climates.
