Reach-in test chambers yog cov cuab yeej tseem ceeb hauv ntau qhov kev lag luam, muab kev tswj hwm ib puag ncig rau kev sim cov khoom thiab cov ntaub ntawv nyob rau hauv qhov tshwj xeeb kub thiab av noo. Cov chav muaj ntau yam no ua lub luag haujlwm tseem ceeb hauv kev ua kom cov khoom zoo, kev ntseeg siab, thiab ua raws li cov qauv kev lag luam. Hauv phau ntawv qhia dav dav no, peb yuav tshawb xyuas qhov ntsuas kub thiab av noo ntau rauncav-hauv chav kuaj, lawv cov kev siv, thiab cov yam ntxwv uas cuam tshuam rau cov kev txwv no.
Nkag siab txog Kev Tshawb Fawb Hauv Kev Xeem Chamber Capabilities
Kub Kub Specifications
Reach-in test chambers yog tsim los simulate ntau yam ntawm qhov kub thiab txias. Qhov ntsuas kub ib txwm rau cov chav no txawv nyob ntawm tus qauv tshwj xeeb thiab cov chaw tsim khoom. Txawm li cas los xij, feem ntau tus qauv ncav-hauv chav ntsuas kub muaj qhov kub ntawm -40 degree mus rau +180 degree (-40 degree F txog +356 degree F). Qee cov chav tshwj xeeb tuaj yeem ua tiav qhov kub thiab txias dua, nrog rau qhov ntev ntawm -70 degree mus rau +200 degree (-94 degree F mus rau +392 degree F) lossis dhau ntawd.
Nws yog ib qho tseem ceeb kom nco ntsoov tias qhov kub thiab txias stability thiab uniformity nyob rau hauv lub chamber yog ib qho tseem ceeb raws li tag nrho cov ntau yam. High-quality ncav-hauv chav kuaj ntsuas kub qhov tseeb nyob rau hauv ± 0.5 degree rau ± 1 degree, ua kom ntseeg tau zoo thiab txhim khu kev qha cov txiaj ntsig.
Humidity Control Muaj peev xwm
Kev tswj cov av noo yog lwm qhov tseem ceeb ntawm ntau qhov chaw kuaj mob. Tus txheeb ze humidity (RH) ntau rau cov chav no yog nyob nruab nrab ntawm 10% thiab 98%. Txawm li cas los xij, nws yog ib qho tseem ceeb kom nkag siab tias qhov ua tau zoo ntawm cov av noo feem ntau yog nyob ntawm lub chamber qhov kub thiab txias.
Ntawm qhov kub thiab txias, condensation tuaj yeem tshwm sim, txwv cov av noo siab tshaj plaws. Hloov pauv, ntawm qhov kub siab dua, nws yuav nyuaj dua los tswj cov av noo siab. Yog li ntawd, qhov ua tau zoo ntawm cov av noo yuav nqaim dua ntawm qhov kub thiab txias.
Kev sib xyaw ua ke ntawm Kev Kub Ntxhov thiab Humidity Control
Ntauncav-hauv chav kuajmuab kev sib xyaw ua ke kub thiab av noo tswj, tso cai rau kev hloov kho ib txhij ntawm ob qho tib si. Qhov no feature yog tshwj xeeb tshaj yog muaj nqis rau kev ntsuam xyuas cov khoom uas rhiab rau ob qho tib si kub thiab av noo variations. Daim duab psychrometric, uas qhia txog kev sib raug zoo ntawm qhov kub thiab av noo, feem ntau yog siv los txiav txim siab qhov ua tau zoo ntawm ob qhov kev ntsuas no hauv ib chav tshwj xeeb.
Nws yog ib qho tsim nyog sau cia tias qee qhov kev ntsuam xyuas qib siab tuaj yeem ua tiav cov ntsiab lus dew tsawg li -40 degree, ua rau kev sim hauv cov xwm txheej qhuav heev. Qhov peev xwm no tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau kev lag luam uas cuam tshuam nrog cov khoom siv los yog cov khoom siv ya raws.
Factors Influencing Temperature and Humidity Range
Chamber Loj thiab Tsim
Qhov loj thiab tsim ntawm chav ntsuas ncav cuag tuaj yeem cuam tshuam nws qhov ntsuas kub thiab av noo. Cov chav loj dua tuaj yeem xav tau cov cua sov thiab cua txias dua kom tswj tau cov xwm txheej zoo ib yam thoob plaws qhov chaw sim. Tsis tas li ntawd, lub chamber lub rwb thaiv tsev zoo thiab cov ntaub ntawv siv hauv nws cov kev tsim kho ua lub luag haujlwm tseem ceeb hauv kev ua tiav thiab tswj qhov kub thiab txias.
Qee qhov chaw kuaj mob tuaj yeem ua rau cov tub yees cascade, uas tso cai rau kev hloov pauv sai dua thiab muaj peev xwm ncav cuag qhov kub siab tshaj. Cov txheej txheem sophisticated no tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau kev lag luam uas yuav tsum tau ceev thermal cycling los yog kuaj ntawm qhov kub qis heev.
Ib puag ncig tej yam kev mob
Cov xwm txheej nyob ib puag ncig ntawm chav ntsuas qhov ncav cuag tuaj yeem cuam tshuam nws qhov kev ua tau zoo, tshwj xeeb ntawm kev tswj cov av noo. Chambers ua haujlwm nyob rau hauv high-humidity ib puag ncig yuav nyuaj kom ua tiav cov av noo tsawg heev yam tsis muaj cov tshuab dehumidification ntxiv. Piv txwv li, nyob rau hauv cov huab cua arid, tswj cov av noo siab yuav xav tau ntau zog humidification peev xwm.
Txhawm rau txo cov teebmeem no, ntau lub tuam txhab pom zoo kom txhim khoncav-hauv chav kuajhauv chav ntsuas kub. Txoj hauv kev no pab ua kom muaj kev ua tau zoo ib yam thiab txo qhov kev nyuaj siab ntawm lub chamber lub tshuab, uas tuaj yeem ua rau nws lub neej ua haujlwm ntev.
Test Specimen yam ntxwv
Qhov xwm txheej ntawm cov qauv kuaj lawv tus kheej tuaj yeem cuam tshuam qhov ua tiav qhov ntsuas kub thiab cov av noo nyob rau hauv qhov ncav cuag-hauv chav kuaj. Cov qauv loj lossis tuab tuaj yeem nqus lossis tso tawm cov cua sov ntau, cuam tshuam rau lub chamber lub peev xwm los tswj cov xwm txheej ruaj khov. Ib yam li ntawd, cov ntaub ntawv uas yooj yim nqus los yog tso tawm cov dej noo tuaj yeem cuam tshuam lub chamber cov av noo.
Txhawm rau suav rau cov xwm txheej no, nws yog ib qho tseem ceeb uas yuav tsum xav txog cov thermal huab hwm coj thiab cov khoom noo noo ntawm cov qauv kuaj thaum xaiv qhov ntsuas qhov ntsuas qhov ntsuas. Qee cov chav ua haujlwm siab heev muaj cov kev tswj hwm kev hloov pauv uas tuaj yeem hloov kho lawv txoj haujlwm raws li cov yam ntxwv ntawm cov khoom raug kuaj, kom ntseeg tau tias muaj tseeb thiab ruaj khov ib puag ncig.
