Lub Chiller ua haujlwm li cas?
Cov txheej txheem ua haujlwm nyob rau hauv ib lub voj, tab sis peb yuav pib qhov twg cov cua txias nruab nrab cuam tshuam nrog koj cov khoom siv txheej txheem.
Lub kaw lus lub coolant absorbs thermal zog los ntawm koj cov txheej txheem, feem ntau ua rau ib theem hloov mus rau hauv ib tug roj. Lub gaseous refrigerant ces circulated mus rau ib tug condenser uas expels lub tshav kub los ntawm evaporative condensation los yog ib tug txias ntauwd. Qhov kev sib pauv cua sov no condenses cov cua txias nruab nrab rov qab rau hauv cov kua txias uas xa rov qab mus rau cov txheej txheem cua sov kom pib lub voj voog dua.
Dab tsi yog hom Coolants siv hauv Chillers?
Hom coolant siv nyob rau hauv lub chiller yog raws li cov txheej txheem xav tau thiab cov nqi txiav txim siab. Cov dej txias tshaj plaws uas siv yog dej los yog cov dej sib tov thiab lwm yam khoom siv nrog cov khoom siv hluav taws xob tsim nyog - zoo li glycol compounds.
Dej
Kev siv dej ua cov kua chiller yog ib qho kev lag luam vim tias feem ntau cov dej tuaj yeem yooj yim los ntawm cov nqi tsawg. Xwb, purified (deionized dej, rov qab osmosis) dej yuav siv tau nyob rau hauv ib tug dej-raws li chiller kom ua tau ib tug ntau dua txias efficiency.
Glycol
Glycol raws li coolants yog tsim los ntawm ethylene glycol los yog propylene glycol. Txawm hais tias ob qhov sib txawv no muaj lub cev zoo sib xws, lawv yuav tsum tsis txhob sib xyaw. Qhov zoo tshaj plaws uas glycol coolants confer yog kev txhim kho kev tiv thaiv corrosion thiab antifreeze zog.
Vim li cas Glycol siv rau cua txias
Kev siv glycol-dej sib tov ua lub chiller coolant muaj ntau yam txiaj ntsig ntawm kev siv cov dej dawb ua cov kua chiller. Cov txiaj ntsig zoo no yog vim nws lub cev tshwj xeeb uas suav nrog qhov chaw qis qis dua li dej.
Dej vs. Glycol Kub Hloov
Rau cov dej tsis muaj impurities, qhov chaw khov yog 32 degree F uas yog ntau dua piv rau cov ntshiab ethylene glycol uas hloov mus rau nws cov khoom-lub xeev ntawm 8.9 degree F. Thaum lub glycol-dej sib tov hloov, lub freezing point ntawm lub coolant kuj. kev hloov. Piv txwv li, 10 feem pua ethylene glycol yuav khov ntawm 25.9 degree F thaum lub 60 feem pua glycol tov yuav khov ntawm -63 degree F.
Los ntawm cov kev soj ntsuam saum toj no, nws yog qhov tseeb tias glycol muaj cov khoom siv tub yees uas tsim nyog rau kev siv hauv chillers xav kom ua haujlwm hauv qhov chaw kub qis. Nyob rau hauv cov thermal tej yam kev mob, ib tug dej coolant yuav khov thiab cuam tshuam chiller ncig thaum lub sij hawm poob tag nrho efficiency.
Los ntawm qhov sib txawv, kev siv glycol-raws li chiller yuav ua kom zoo dua ntawm nws cov khoom ua kom tsis muaj zog kom ntseeg tau tias cov coolant tseem nyob hauv lub xeev cov dej uas xav tau.

Glycol Chiller vs. Dej Chiller
Glycol thiab dej chillers tuaj yeem siv los ua kom txaus siab rau cov cua sov uas tsim los ntawm koj cov txheej txheem tsim khoom. Qhov sib txawv tseem ceeb ntawm ob hom chiller nyob rau hauv kev hloov pauv hauv lawv cov ntsiab lus khov thiab lawv cov peev xwm ua kom sov.
Ntshiab glycol los yog kev sib xyaw ntawm glycol thiab dej muaj qhov qis qis qis dua li cov dej ntshiab. Los ntawm kev cuam tshuam, glycol-raws li chillers zoo dua rau qhov chaw qis qis. Hloov pauv, dej muaj peev xwm zoo dua khaws thiab ua kom sov los ntawm cov txheej txheem cuam tshuam tshaj li qhov sib xyaw glycol tuaj yeem. Yog li ntawd, qhov ua tau zoo ntawm kev hloov hluav taws xob rau cov dej chiller yuav siab dua li ntawm glycol chiller.
Zuag qhia tag nrho, cov neeg ua haujlwm yuav tsum xav txog qhov kub thiab txias rau qhov chaw zaum ua ntej xaiv hom chiller.
Glycol Chiller System Ua Haujlwm Li Cas?
Glycol chiller cog yog tsim los ntawm cov tub yees thiab tubing uas muaj glycol-dej sib tov ua kom txias. Chilled kua los ntawm chav tsev tub yees yog channeled los ntawm cov kav dej txuam nrog ib tug thermal exchanger nyob ib ncig ntawm ib tug rhuab txheej txheem. Tom qab nqus cua sov los ntawm cov txheej txheem cuam tshuam, cov cua sov ua kom sov yog rov qab mus rau chav tsev tub yees kom txias tom qab uas cov txheej txheem rov ua dua.
Feem pua Glycol hauv Chilled Water Systems
Rau ntau hom chiller, ethylene glycol yog tov nrog dej ntawm qhov sib piv ntawm 60/40. Qhov feem pua siab dua ntawm glycol boosts qhov sib xyaw ntawm cov khoom ua kom tsis muaj zog. Qhov no yog qhov tseem ceeb nyob rau hauv rooj plaub uas yuav tsum tau ua kom txias sai. Hauv cov xwm txheej no, cov txheej txheem tuaj yeem ua kom txias rau qhov kub qis heev yam tsis muaj qhov txias txias hauv nws cov kav dej.
Ntawm no cia peb pom ib qho piv txwv rau glycol dej chiller rau dej txias
12000L / hr haus dej txias los ntawm 25degrees mus rau 4degrees, cov neeg siv khoom xav tau dej txias chiller, uas yuav tsum tau txuas cov cua txias ntauwd.
Rau qhov glycol sab cua txias muaj peev xwm xam, peb xaiv qhov muaj peev xwm txias {{0}}m3/h*(25-4)/0.86*1.1=323kw, raws li 1C qhov hluav taws xob.
Lub phaj kub hloov pauv tsim: 12000L / hr haus 25degress inlet thiab 4degress qhov hluav taws xob, glycol sab 60m3 / hr 1degrees inlet thiab 5degrees qhov hluav taws xob.
Wb pom dej chiller txias ntauwd system ua haujlwm hauv paus ntsiab lus
Dej txias chiller siv dej los ntawm ib qho kev tso cua txias sab nraud kom tsis txhob muaj cua sov los ntawm cov roj cua txias hauv lub condenser ua ntej nws hloov mus rau theem ua kua..
