<p>Summary Helium is transported and distributed in mobile bulk storage tanks (1) and filled at filling stations (3) into smaller consumer tanks (11). The contents of the tank takes up heat continuously from the surroundings, which leads to a continuous rise in temperature and pressure of the contents of the tank, so that the original liquid helium above a critical pressure turns into a singlephase supercritical fluid. The bulk storage tank (5) may at need be brought to a recooling station (2) which by a recooler group (4) which exhibits a closed cooling circuit cools a heat-exchanger (29) which cools the contents of the bulk storage tank (5). Through the extraction of heat the contents of the bulk storage tank (5) may be cooled as often as desired to a usually standardized temperature. (Figure 1)</p> |
