Megacool txias tsho khuam muab kev tiv thaiv thermal rau cov neeg ua haujlwm nyob rau hauv siab - qhov kub thiab txias, ua kom muaj kev nplij siab hauv lub cev. Tam sim no, Tuam Tshoj muaj tshaj 60 qhov kub siab - mines, nrog 38 mines tshaj 30℃. Raws li cov peev txheej thee ntiav tsawg zuj zus, yav tom ntej mining yuav tsom mus rau qhov tob tob, qhov uas muaj kev phom sij thermal tau tshwm sim raws li qhov thib rau kev pheej hmoo loj tom qab roj, hluav taws kub, thee plua plav, av siab, thiab dej txaus ntshai, cuam tshuam loj heev rau kev sib sib zog nqus mining. Tsis tas li ntawd, kev lag luam xws li steel smelting nthuav tawm cov neeg ua haujlwm rau qhov kub thiab txias txog li 50 degree. Kev kub hnyiab ntev ua rau qaug zog, txo qis kev tsim khoom, thiab kev pheej hmoo ntawm lub cev xws li electrolyte tsis txaus thiab lub cev qhuav dej, ua rau cov neeg ua haujlwm muaj kev noj qab haus huv thiab kev nyab xeeb. Yog li ntawd, cov khaub ncaws txias txias rau siab - qhov kub thiab txias ib puag ncig muaj qhov tseem ceeb.
1. Kev faib tawm ntawm lub tsho txias txias
(1) Los ntawm Cov Qauv Khaub Ncaws
a. Localized Cooling Vest
Raws li kev hloov pauv hauv cheeb tsam hauv tib neeg cov cua sov tsim thiab dissipation, cov khaub ncaws no tsom rau thaj chaw uas muaj cov metabolism hauv siab, feem ntau ntawm lub taub hau thiab lub cev. Cov kev tshawb fawb qhia tau hais tias lub cev muaj qhov siab tshaj plaws ntawm cov metabolic tus nqi thiab lub peev xwm kub thaum ua haujlwm. Los ntawm leveraging kub gradients ntawm qhov chaw txias thiab conductive media, localized txias garments tshem tawm qhov xav tau rau lwm lub hwj chim. Lawv cov qauv yooj yim, hnav, ua haujlwm txias, thiab kev ua haujlwm ua rau lawv siv dav hauv kev lag luam thiab txhua hnub.
b. Puv -lub cev Txias Vest
Cov khaub ncaws no muab kev ua kom txias rau lub cev thiab cov ceg, ua kom muaj kev nplij siab tag nrho. Lawv feem ntau yog tshwj tseg rau qhov chaw kub heev (piv txwv li, cov chaw tsim khoom, thaj chaw tshuaj lom neeg) lossis cov xwm txheej uas yuav tsum muaj tag nrho - lub cev tiv thaiv cov pa phem.
(2) Los ntawm Cua Txias Nruab Nrab
a. Cua-Coled Vest
Siv cov cua txias, cov khaub ncaws no ntiav cov tub yees txias kom txias cua, uas yog huv si thiab xa mus los ntawm cov tubing lossis cov khaubncaws sab nraud povtseg kom txias cov neeg hnav. Lub tshuab cua txias cia siab rau kev txhim kho hws evaporation thiab convective tshav kub hloov.
Qhov zoo: Muaj huab cua ntau, ua kom txias txias, ua haujlwm siab.
Kev txwv: Huab cua- cov khaubncaws sab nraud povtseg txwv tsis pub txav mus los, ua rau kev ua haujlwm tsis zoo hauv qhov chaw kaw (xws li mines). Cov tshuab tub yees ua rau muaj kev phom sij tawg nyob rau hauv ib puag ncig uas yuav tsum tau ua kom nruj tiv thaiv kev tawg.
b. Theem Hloov Txias Vest
Ua haujlwm ntawm kev ua kom txias txias, cov khaub ncaws no sib xyaw cov ntaub ntawv hloov pauv theem (PCMs) uas nqus cua sov thaum lub sijhawm hloov pauv (xws li cov khoom ua kua). Piv txwv li:
Khoom rau kua PCMs: Thaum ambient kub tshaj lub PCM lub theem hloov point, cov khoom melts, absorbing tshav kub kom txias lub cev. Hloov pauv, thaum kub poob qis dua theem hloov pauv, PCM solidifies, tso cov cua sov kom tswj tau qhov sib npaug thermal. Feem ntau PCMs: Ice, dej khov qhuav, paraffin, hydrogels, thiab superabsorbent polymers, nrog rau cov dej khov, hydrogels, thiab paraffin feem ntau.
Qhov zoo:
- Tus nqi qis, tsim qauv yooj yim, kev siv yooj yim, thiab kev ua haujlwm dual (txias thiab rwb thaiv tsev).
- Ntau hom PCM kev xaiv, suav nrog cov khoom siv organic, inorganic, thiab hybrid, pab cov ntawv thov thoob plaws mining, metallurgy, thiab industrial sectors.
- Ua kom ruaj khov "microclimate" hauv cov ris tsho, ua kom muaj kev nplij siab.
- Kev Tshawb Fawb Txog Kev Tshawb Fawb: PCMs yog qhov hotspot hauv kev tshawb fawb txog kev tswj xyuas thermal vim lawv yoog tau thiab ua haujlwm tau zoo.
2. Kev Tshawb Fawb Kev Txhim Kho hauv Theem Hloov Txias Vest
Hauv kev kawm txog theem hloov cua txias tsho, kev nce qib tuaj yeem ua raws li cov hauv qab no:
