Dab tsi yog theem hloov cov ntaub ntawv
Theem hloov pauv (PCMS) yog cov tshuaj uas tuaj yeem khaws thiab tso tawm cov hluav taws xob ntau npaum li lawv hloov ntawm ib theem rau lwm tus, xws li los ntawm cov khoom ua kua lossis kua rau roj. Cov ntaub ntawv no tau siv rau cua sov cia thiab kev tswj hwm hauv ntau daim ntawv thov, xws li hauv kev ua haujlwm tsim tsev, tub yees, thiab thermal kev cai hauv cov khaub ncaws.
Thaum ib lub PCM nqus tshav kub, nws undergoes ib theem hloov, xws li melting, thiab khaws cia lub zog thermal raws li latent tshav kub. Thaum ib puag ncig kub tsawg dua, PCM solidifies thiab tso tawm cov cua sov khaws cia. Cov cuab yeej no tso cai rau pcms los ua kom muaj kev ywj pheej thiab siv hluav taws xob ua kom sov nyob hauv ntau qhov chaw ib puag ncig.
PCMS muaj nyob rau hauv ntau hom ntawv, suav nrog cov khoom siv organic, thiab cov ntaub ntawv eutsecic, txhua tus nrog melting thiab khov cov ntsiab lus kom haum cov kev siv tshwj xeeb. Lawv muaj nce zuj zus hauv kev siv nyob rau hauv kev ruaj khov thiab lub zog-txuag thev naus laus zis kom txo cov cua sov noj thiab txhim kho kev ua haujlwm thermal.
Qhia cov ntaub ntawv PCM
Theem Hloov Cov Ntaub Ntawv (PCMs) muab ob peb qhov zoo hauv ntau cov ntawv thov:
1. Thermal Zog Cia: Pcms tuaj yeem khaws thiab tso tawm cov hluav taws xob ntau thaum theem hloov, tso cai rau kev tswj hwm hluav taws xob ntau thiab kev cia siv.
2. Cov kev cai ntsuas kub tuaj yeem pab tswj qhov kub thiab txias hauv cov tuam tsev, tsheb, thiab khoom siv hluav taws xob zoo thiab ruaj khov.
3. Zog txuag hluav taws xob: los ntawm khaws cia thiab tso cov cua sov zog, cov PCMs tuaj yeem txo cov cua sov txuas ntxiv lossis cua txias, ua kom muaj zog txuag thiab txhim kho kev ua haujlwm.
4. Chaw-txuag: piv rau cov tsoos thermal cia lub tshuab, pcms tuaj yeem muab lub zog cia siab ceev, tso cai rau kev tsim qauv ntau thiab cov chaw-ua tau zoo.
5. Cov txiaj ntsig ib puag ncig: Kev siv PCMs tuaj yeem pab txhawb cov tsev cog khoom roj emissions, ua rau lawv xaiv kom ruaj khov rau qhov kev tswj hwm cua sov.
6. Yooj yim: pcms muaj nyob rau hauv ntau hom ntawv thiab tuaj yeem ua kom ntsuas qhov ntsuas kub thiab cov kev siv, muab kev hloov kho hauv kev tsim qauv thiab kev siv.
Zuag qhia tag nrho, PCMS muaj ntau cov txiaj ntsig uas ua rau lawv muaj kev daws teeb meem rau thermal zog cia thiab kev tswj hwm hauv kev lag luam sib txawv.
Dab tsi yog qhov sib txawv ntawmGel Cov Khoom Noj Kom QhuavThiabPCM lub Freezer Pob?
Gel pob thiab theem hloov pauv hloov (PCMS) yog ob qho tib si siv rau hluav taws xob cia thiab kev tswj hwm, tab sis lawv muaj qee qhov sib txawv:
1. Cov khoom sib xyaw: cov pob gel feem ntau muaj cov khoom siv gel zoo li, feem ntau dej, uas khov rau hauv lub xeev ruaj khov thaum txias. PCMS, ntawm qhov tod tes, yog cov khoom uas yauv hloov theem, xws li los ntawm cov khoom rau kua, khaws cia thiab tso tawm lub zog thermal.
2. Qhov ntsuas kub ntau: Cov pob gel feem ntau tau tsim los tswj qhov kub ntawm cov dej khov, feem ntau 0 ° F). Pcms, txawm li cas los xij, tuaj yeem ua rau muaj cov engineed kom muaj theem hloov chaw sov, tso cai rau qhov ntsuas kub thiab txias rau ntau dua li ntau dua.
3. Rov ua dua: Cov pob gel feem ntau siv lossis muaj cov rov qab tsawg dua, raws li lawv tuaj yeem txwv sijhawm lossis siv sijhawm dua. PCMS, nyob ntawm cov khoom siv tshwj xeeb, tuaj yeem tsim tau rau ntau theem hloov mus los mus los, ua rau lawv muaj ntau ruaj thiab ntev ntev.
4. Lub zog ntom ntom: PCMs feem ntau muaj lub zog zoo dua kev ceev piv rau cov hnab nyiaj gel, lub ntsiab lus lawv tuaj yeem khaws ntau lub zog rau ib lub ntim lossis qhov hnyav.
5. Daim ntawv thov: Cov pob gel feem ntau siv rau cov ntawv thov luv luv lossis ua kom khov, xws li hauv cov thawv txias lossis lub hom phiaj kho mob. Cov PCMs tau siv nyob rau hauv cov kev siv dav dav, suav nrog kev ua kom tsim tsev, thermal kev cai hauv cov khaub ncaws, thiab kub-tswj kev xa khoom thiab chaw khaws khoom.
Hauv cov ntsiab lus, thaum ob qho tib si gel pob thiab cov PCMs tau siv rau kev tswj thermal, pcms muaj ib qho dav dav, thiab cov ntawv thov ntau dua piv rau cov pob gel.
