Nrog txoj kev loj hlob sai ntawm kev lag luam khoom noj khoom haus, kev khaws cia cov zaub mov tshiab yog qhov tseem ceeb, tsis hais seb nws yog kev lag luam ntim khoom noj ua ntej lossis kev lag luam ntim khoom noj ib txwm muaj. Txo qhov kub thiab txias yog ib txoj hauv kev tseem ceeb los khaws cov zaub mov, thiab TRIPU tau tsim ob hom kev ceev-khov tshuab rau zaub mov ceev-khov thiab khaws cia: fluorine refrigerant qhov ceev-freezing tshuab thiab kua nitrogen qhov ceev-freezing tshuab. Ob yam khoom muaj kev ua haujlwm siab thiab ruaj khov hauv kev ua kom txias sai thiab khaws cia cov zaub mov. Txawm li cas los xij, muaj ntau qhov sib txawv ntawm ob yam khoom, thiab peb yuav tsum xaiv cov khoom tsim nyog raws li cov txheej txheem ntau lawm.
Cov kua nitrogen tunnel ceev-freezing tshuab yog dav siv nyob rau hauv kev lag luam rau high-end khoom noj khoom haus. Nws muaj cov yam ntxwv ntawm lub sijhawm khov luv luv thiab cov khoom khov khov zoo vim yog cov yam ntxwv ntawm qhov kub thiab txias ntawm cov kua nitrogen. Thiab vim li no, cov cell membrane yuav tsis raug puas tsuaj, yog li khaws cov saj zoo tshaj plaws thiab kev ntxhib los mos. Tsis tas li ntawd, nws muaj qhov zoo ntawm cov suab nrov tsawg, cov qauv yooj yim, cov hneev taw me me, thiab cov khoom siv qis. Txawm li cas los xij, nws yuav tsum tau ntxiv cov kua nitrogen tas li, thiab tus nqi siab ntawm cov kua nitrogen yog nws qhov tsis zoo.
Piv nrog rau chav tsev ua kua nitrogen, cov fluorine refrigerant chav tsev feem ntau txawv nyob rau hauv uas nws tsis tas yuav ntxiv cov tub yees rau lub sijhawm ntev. Nws tsuas yog siv cov nqi siv hluav taws xob ntawm cov khoom siv nws tus kheej hauv cov nqi khiav lag luam. Los ntawm qhov kev xav ntawm kev siv mus sij hawm ntev, tus nqi siv tom ntej ntawm chav tsev fluorine refrigerant yog qis dua li ntawm cov kua nitrogen. Txawm li cas los xij, nws cov khoom siv raug nqi siab, thiab nws siv ntau qhov chaw. Tsis tas li ntawd, nws ua rau cov khoom noj cell membrane puas, ua rau lub saj tsis zoo li cov kua nitrogen. Tsis tas li ntawd, nws tseem muaj lub sijhawm khov ntev dua li cov kua nitrogen, thiab tom qab ua haujlwm tas li, nws yuav tsum tau nres rau qee lub sijhawm ntawm defrosting, uas kuj yog qhov tsis zoo.
