Abstract The aim of this project is to design and optimise a heat exchanger that would be able to cool the hydrogen according to SEA TIR J2601. The initial design will be build upon static calculations for a 5kg A70 filling. A dynamic simulation model will be made for analysing the filling and a test bench will be made in order to validate the dynamic simulation. Further will the project also contain a economical feasibility study of a hydrogen filling station. The results from the test bench conrmed that the simulation was valid. Further the simulation showed that static calculations were imprecise and not suited for designing a heat exchanger. The simulation was also used to optimise the heat exchanger so that it could live up to the requirements given by the the standard. The simulation showed that 15 tubes with 3 bend each were needed in a tube and shell heat exchanger to meet the demand for the test facility. The cross section for the brine ow should be 0; 033 meters in width and 0; 504 meters in hight, with the tubes distributed equally. Dierent further optimisation can be made if the heat exchanger design is changed, more bends and smaller ducts will increase the local heat transfer number. Further, economical calculations on a hydrogen filling station shows, that the design of refrigeration facility has very little impact on the net present value.
