Iimfuno ezikhethekileyo zokufunxa kwiikomityi zokufunxa zensimbi engenasici ziya kwahluka ngokoyilo lwemveliso, imigangatho yokuvelisa, kunye neemfuno zomenzi. Ngokuqhelekileyo, i-vacuum ilinganiswa kwiiPascals. Nalu uluhlu lwevacuum olunokubakho lwereferensi:
Uluhlu oluqhelekileyo oluqhelekileyo:
Iimfuno zevacuum eziqhelekileyo zokuvelisa iimagi ze-thermos zensimbi ezingenasici zinokusuka kwi-100 Pascal ukuya kwi-1 Pascal. Olu luhlu luqhelekileyo kwaye lunokuhlangabezana neemfuno zokugquma ukuze kusetyenziswe yonke imihla.
Iimfuno eziphezulu:
Ezinye iiflasks zevacuum eziphezulu zinokufuna amanqanaba aphezulu evacuum, anjengaphantsi kwe-1 Pascal. Oku kunokuphucula ngakumbi i-insulation effect, evumela i-thermos ukugcina ubushushu ixesha elide.
Nceda uqaphele ukuba abavelisi abohlukeneyo kunye neemveliso banokuba neemfuno ezahlukeneyo zevacuum, ke amaxabiso athile aya kwahluka ngokusekwe kuyilo lwemveliso, iinkcukacha zobugcisa, kunye nokuma kwemarike. Abavelisi bahlala bebonelela ngeemfuno ezikhethekileyo zokucoca kumaphepha achaza imveliso okanye iincwadana zemveliso. Ngexesha lenkqubo yokuvelisa, qinisekisa ukuba amanyathelo okucoca enziwa ngokungqongqo ngokuhambelana nemigaqo yomenzi ukuhlangabezana neemfuno zoyilo lwemveliso kunye nemigangatho yokusebenza.
