20.500.12556/RUL-149644 Zamrzovanje vode pri sobni temperaturi pod visokim tlakom Water freezing at room temperature under high pressure Na podlagi faznega diagrama vode je teoretično možno vodo zamrzniti pri sobni temperaturi in dovolj visokem tlaku. Razvijajoče se tehnologije na področju ekstremnih okolij nam omogočajo obratovanje pri dovolj visokem tlaku. V tej zaključni nalogi smo predstavili teoretično ozadje tega problema, naredili smo analizo tehnologij, postopkov in materialov, pri katerih bi to bilo možno izvesti. Analizirali smo tudi komponente, ki lahko pri dobljenih pogojih obratujejo: visokotlačne črpalke, ventile, hidravlične valje, režime mazanja in tesnjenje. Rezultati so pokazali, da imamo na voljo komponente, potrebne za obratovanje hidravličnega sistema, s katerimi je zamrzovanje vode pri sobni temperaturi in visokem tlaku možno izvesti. Based on the water phase diagram it is theoretically possible to freeze water at room temperature with sufficiently high pressure. The field of extreme environments and the technologies developing there allow us to work with a sufficiently high pressure. In this work, we have presented the theoretical background of this problem and analysed the technologies, processes and materials that would make this possible. We have also conducted an analysis of the components that can work under these conditions: ultra-high pressure pumps, valves, hydraulic cylinders, lubrication systems and seals. The results showed that the components necessary for the operation of the hydraulic system are present, with which it is possible to freeze water at room temperature and high pressure. voda stisljivost ekstremni pogoji zamrzovanje modul stisljivosti water compressibility extremely high pressure freezing bulk modulus true false false [A.
