Chav tsev yog ib qho chiller muaj peev xwm ua rau cov cua sov tsawg tsawg tshaj 0 ° C rau cov cua txias ua ke xws li kev ua qoob loo, kev ua khoom noj, tshuaj, tshuaj thiab lwm yam khoom lag luam.
Tus qauv ntawm cov uas tsis tshua muaj siab lub hauv siab chiller yog zoo ib yam li cov txheej txheem piston chiller, thiab lub voj voog tub yees kuj muaj ib theem zuj zus thiab hloov ob theem zuj zus. Tsis tas li ntawd, txhawm rau txhawm rau ua haujlwm zoo rau cov chiller, kuj tau siv cov khoom siv hluavtaws xob, kev sib tsoo, cov roj siab dhau lawm, dej, lub cev muaj zog thiab lwm yam kev tiv thaiv tsis zoo.
Tsis tshua muaj pes tsawg tus brine chillers uas siv hauv lub tub yees (tsis tshua muaj dej sov) yog cov tshuaj ethylene glycol kua, kua tshuaj sodium chloride aqueous kua thiab cov tshuaj calcium chloride aqueous kua, tshwj xeeb tshaj yog siv feem ntau siv ethylene glycol kua. Cov kev ntsuas kub ntau yog raws li nram no: ethylene glycol aqueous solution 4 ~ -20 ℃, sodium chloride kua-15 ~ 25 ℃, calcium chloride aqueous kua-20 ~ -45 ℃.
Raws li cov lag luam sib txawv, tsis tshua muaj qhov kub ntxhua dej kub tsis zoo li qub, yuav tsum yog raws li tus neeg siv cov kev xav tau, tab sis nws yuav tsum raug sau tseg tias cov dej ntsev thiab ntsev dej kom zoo, yog li yuav tsum ua kom cov brine concentration Cov chiller hauv cov evaporator Tsis khov. Qhov tiag tiag siv ntawm qhov kub thiab txias, yuav tsum siab tshaj lub qhov freezing point of 5 ~ 8 ℃.
