Txhawm rau kom tsis txhob muaj kev puas tsuaj rau cov khoom siv chiller los ntawm qhov kub thiab txias ib puag ncig, cov cuab yeej yuav tsum tau muab tso rau hauv lub sijhawm. Piv txwv li, chillers, kav dej, twj tso kua mis, txias yees thiab terminals, thaum lub ambient kub yog qis dua xoom, nco ntsoov tso dej ua ntej.
Cov hauv qab no muab cov kev ntsuas dej rau kev lag luam chillers hauv lub caij ntuj no.
1. Condenser: Qhib lub hau kawg ntawm lwm qhov kawg ntawm cov kav dej. Tom qab qhib, thov xyuam xim rau unscrew lub hau kawg thiab screws.
2. Evaporator: Qhib lub valve hauv qab ntawm qhov sib txuas ntawm evaporator kom ntws tag nrho cov dej. Nws raug nquahu kom ua kom lub qhov dej ntws ib txwm qhib rau lub caij ntuj no thiab tua cov dej ua ntej pib lub tshuab rau xyoo tom ntej.
3. Cov kav dej thiab cov twj tso kua mis: ntws cov dej hauv cov kav dej thiab cov twj tso kua mis mus rau qhov chaw qis.
4. Txias ntauwd: Qhib lub qhov dej ntws ntawm qhov qis tshaj plaws ntawm qhov txias ntauwd dej tais kom ntws cov chassis.
5. Xaus: Muaj lub qhov dej ntws hauv qab ntawm lub kauj, thiab lub qhov dej ntws tawm kuj qhib. Lub valve feem ntau qhib rau lub caij ntuj no.
Thaum nruab hnub lossis hmo ntuj, lub twj tso kua mis yuav tsum tau ua haujlwm. Yog tias tsis siv sijhawm ntev, cov dej yuav tsum tau ntws. Yog tias huab cua tsis zoo (qhov ntsuas kub qis dua -10 ° C), nws raug nquahu kom tso tseg cov kua dej thiab ntxiv cov tshuaj tiv thaiv rau cov dej.
Tus yuam sij rau kev tiv thaiv kom khov: ntxiv cov tshuaj tiv thaiv kab mob kom tsim nyog.
Lub npe tag nrho ntawm antifreeze coolant yog antifreeze coolant, uas yog, coolant nrog antifreeze muaj nuj nqi, uas muaj peev xwm tiv thaiv lub coolant los ntawm khov nyob rau hauv lub caij ntuj no txias, ncua lub neej kev pab cuam ntawm laser thiab lub internal pipeline ntawm lub cooler, thiab puas lub pipeline foob. .
Muaj ntau hom tshuaj tiv thaiv kab mob sib txawv ntawm kev ua lag luam, ntau tus neeg siv khoom tsis paub yuav xaiv, xa lossis xaiv qee cov tshuaj tiv thaiv kab mob uas tsis haum rau peb cov chillers.
Qhov tseeb, chillers muaj qee qhov kev xav tau rau kev tiv thaiv kab mob. Kev xaiv tsis raug lossis siv tsis raug yuav ua rau cov kav dej sab hauv ntawm cov khoom puas. Cov kev ua haujlwm tshwj xeeb ntawm cov chillers rau kev tiv thaiv kab mob yog raws li hauv qab no.
1. Tshuaj stability;
2. Kev ua haujlwm zoo antifreeze;
3. Tsawg kub viscosity;
4. Anti-corrosion thiab anti-xeb;
5. Cov roj hmab sealing raj tsis muaj kev nthuav dav thiab yaig.
Feem ntau cov tshuaj tiv thaiv kab mob yog ethylene glycol thiab propylene glycol. Cov tshuaj tiv thaiv kab mob no tuaj yeem siv ncaj qha rau hauv qhov tsim nyog piv raws li qhov xav tau ntawm qhov kub thiab txias.
Tab sis leej niam cawv (hom concentrated) tsis tuaj yeem siv ncaj qha, tab sis yuav tsum tau hloov kho rau qee qhov concentration nrog dej demineralized raws li qhov xav tau ntawm kev ua haujlwm kub. Cov hauv qab no qhia txog kev siv tshuaj tiv thaiv kab mob hauv lub khw.
Lub freezing point ntawm ethylene glycol antifreeze kua hloov nrog kev hloov ntawm ethylene glycol nyob rau hauv cov kua aqueous. Thaum lub ntim concentration qis dua 56%, qhov concentration ntawm ethylene glycol nyob rau hauv cov kua aqueous nce thiab qhov khov ntawm qhov qis qis. Nws yuav nce ntxiv mus txog thaum nws qhov chaw khov kho nce mus rau -13 ° C ntawm 100% concentration. Qhov no yog ib qho laj thawj tseem ceeb vim li cas cov tshuaj tiv thaiv kab mob tsis tuaj yeem ncaj qha ntxiv rau lub freezer rau kev tiv thaiv kab mob.
