Raws li kev siv thev naus laus zis dehumidification, cov ntsiab lus tseem ceeb ntawm kev ua haujlwm ntawm cov dej noo- cov khoom pov thawj tuaj yeem faib dav rau hauv hluav taws xob (lub cev adsorption / molecular sieve), semiconductor condensation, nitrogen-purged (nitrogen txee), thiab compressed cua hom. Hluav taws xob ya raws-cov ntaub ntawv pov thawj siv cov khoom siv hygroscopic zoo heev (xws li 4A molecular sieves) los nqus dej noo hauv lub txee; ib zaug saturated, cov dej noo yog vaporized ntawm cua sov thiab tshem tawm ntawm lub txee, yog li regenerating lub desiccant. Cov txheej txheem no cuam tshuam nrog kev ua haujlwm tsis sib xws, kev ua haujlwm dehumidification tswj los ntawm cov duab-memory alloy valve uas tswj qhov qhib thiab kaw ntawm qhov chaw nres nkoj tso pa. Qhov zoo ntawm txoj kev no suav nrog kev siv hluav taws xob tshwj xeeb, kev siv yooj yim, thiab kev saib xyuas -dawb tsim. Tsis tas li ntawd, txij li thaum lub adsorption thiab desorption ntawm noo noo yog lub cev cov tshuaj tiv thaiv, cov desiccant tuaj yeem siv rov qab siv tsis tau tas li; Tsis tas li ntawd, cov molecular sieves tseem adsorb noo noo txawm tias thaum muaj hluav taws xob hluav taws xob. Qhov tsis zoo suav nrog qhov txo qis qis ntawm cov av noo, qhov nce hauv cov txee sab hauv qhov kub thiab txias thaum lub sij hawm tshem tawm cov dej noo, qhov sib piv ntawm cov dehumidification module, thiab qis dua hauv cov av noo tswj; Tsis tas li ntawd, lub sijhawm luv luv ntawm cov dej "rebound" (me ntsis ntawm cov av noo) tuaj yeem tshwm sim hauv lub txee tam sim ntawd tom qab cua sov thiab tshem tawm lub voj voog xaus thiab lub valve kaw.
Semiconductor condensation noo noo-cov khoom pov thawj siv cov khoom siv hluav taws xob semiconductor txias kom txo qhov kub ntawm cov huab cua ntub dej ntws hla lub phaj condensing kom qis dua nws cov dej lwg. Qhov no ua rau cov dej vapor condense rau hauv cov kua dej, uas tom qab ntawd sau thiab ntws tawm. Qhov zoo ntawm txoj kev no suav nrog cov nqi tsim khoom qis dua, tsawg kawg ntawm kev tsim hluav taws xob tsawg, kev sib khi hneev taw, cov av noo meej adjustability, thiab cov suab nrov qis ua haujlwm. Qhov tsis zoo suav nrog tus nqi dehumidification qeeb; susceptibility rau khov rau ntawm condensing phaj-uas impairs dehumidification efficiency-thaum lub ambient kub poob qis dua 16℃; thiab muaj kev pheej hmoo tseem ceeb ntawm "moisture rebound" (qhov twg cov dej condensed re-evaporates rov qab rau hauv lub txee) thaum muaj hluav taws xob tsis ua hauj lwm. Tsis tas li ntawd, lub neej kev pab cuam ntawm lub semiconductor module yog luv luv, thiab lub tsev yuav tsum muaj lub zog txuas ntxiv mus ua haujlwm.
Nitrogen-purged ya raws-cov khoom pov thawj (cov khoom siv nitrogen) ua haujlwm los ntawm kev txhaj tshuaj nitrogen los yog siab -siab, siab -concentration nitrogen gas-uas yog inherently muaj cov av qis heev- mus rau hauv lub txee kom tshem tawm cov huab cua uas twb muaj lawm, yog li tsim kom muaj huab cua tsis tshua muaj - [1-2]. Qhov zoo ntawm txoj kev no suav nrog kev dehumidification sai thiab kev tiv thaiv zoo ntawm oxidation hauv cov khoom khaws cia. Qhov tsis zoo suav nrog tus nqi siab ntawm cov pa roj nitrogen thiab qhov nyuaj ntawm kev ua tiav tsis tu ncua ultra- cov av noo qis- feem ntau qis dua 10% RH lossis 5% RH-siv cov khoom siv nitrogen; Tsis tas li ntawd, tau tsav los ntawm kev txhim kho thev naus laus zis, qee yam kev siv nrog cov kev xav tau nruj heev tau pib hloov mus rau lwm txoj kev dehumidification technologies.
Compressed cua noo-cov khoom pov thawj ua haujlwm los ntawm compressing, ziab, thiab lim cua sab nraud ua ntej txhaj rau hauv lub txee kom tshem tawm cov huab cua ntub tam sim no nyob hauv. Qhov zoo muaj xws li dehumidification sai, lub sijhawm rov qab sai rau cov av noo tom qab lub qhov rooj qhib, thiab lub peev xwm theoretical kom ua tiav cov av noo qis dua 1% RH. Qhov tsis zoo suav nrog kev siv hluav taws xob siab thiab ua haujlwm nrov nrov; lub peev xwm rau compressed cua los qhia impurities-xws li hlau shavings, xeb hais, thiab roj residue- uas paug ib puag ncig sab hauv; qhov yuav tsum tau rau kev pom tshwj xeeb, cov khoom siv ziab, thiab cov kav dej, uas ua rau lub tsev nyuaj rau kev txav chaw; tseem ceeb susceptibility rau fluctuations nyob rau hauv sab nraud ambient humidity; tsis muaj peev xwm tswj tau cov xwm txheej thaum muaj hluav taws xob tam sim ntawd; thiab qhov kev pheej hmoo ntawm cov khoom siv corrosion.
