Flow impedance helium-3
The refrigeration process uses a mixture of two isotopes of helium: helium-3 and helium-4. When cooled below approximately 870 millikelvins, the mixture undergoes spontaneous phase separation to form a He-rich phase (the concentrated phase) and a He-poor phase (the dilute phase). As shown in the phase diagram, at very low temperatures the concentrated phase is essentially pure He, while the dilute phase contains about 6.6% He and 93.4% He. The working fluid is He, whic… WebClearing a Blocked Impedance The following instructions should be performed if a plug has been detected in your impedance valve. 1.
