Cov yeeb nkab nqus tsev uas muaj rwb thaiv tsev yog siv rau kev xa cov khoom siv kub qis, thiab muaj cov nyhuv tshwj xeeb ntawm cov yeeb nkab rwb thaiv tsev txias. Kev rwb thaiv tsev ntawm cov yeeb nkab nqus tsev yog qhov sib piv. Piv nrog rau kev kho cua sov ib txwm muaj, kev rwb thaiv tsev hauv lub tshuab nqus tsev muaj txiaj ntsig zoo dua.

Yuav ua li cas thiaj paub seb lub yeeb nkab nqus tsev puas ua haujlwm tau zoo thaum siv ntev? Feem ntau los ntawm kev soj ntsuam seb phab ntsa sab nraud ntawm lub yeeb nkab VI puas pom qhov tshwm sim ntawm dej thiab te. (Yog tias lub raj nqus tsev rwb thaiv tsev muaj lub ntsuas cua sov, qhov degree nqus tsev tuaj yeem nyeem tau.) Feem ntau, peb hais tias qhov tshwm sim ntawm dej thiab te tsim ntawm phab ntsa sab nraud ntawm lub yeeb nkab VI yog tias qhov degree nqus tsev tsis txaus, thiab nws tsis tuaj yeem ua lub luag haujlwm rwb thaiv tsev tau zoo.

Cov laj thawj ntawm qhov tshwm sim ntawm dej condensation thiab frosting

Feem ntau muaj ob qho ua rau frosting,

● Lub qhov nqus tsev los yog cov vuam xau, ua rau lub tshuab nqus tsev tsawg dua.

● Qhov tso pa roj tawm ntawm cov khoom ua rau lub tshuab nqus tsev tsawg dua.

Lub qhov nqus tsev los yog qhov vuam xau, uas yog cov khoom tsis tsim nyog. Cov chaw tsim khoom tsis muaj cov khoom siv tshuaj xyuas zoo thiab lub kaw lus tshuaj xyuas hauv kev tshuaj xyuas. Cov khoom siv rwb thaiv tsev uas ua los ntawm cov chaw tsim khoom zoo feem ntau tsis muaj teeb meem hauv qhov no tom qab xa khoom.

Cov khoom siv tso pa roj tawm, uas yog qhov tsis zam tau. Thaum siv VI yeeb nkab mus sij hawm ntev, cov hlau tsis xeb thiab cov khoom siv rwb thaiv tsev yuav txuas ntxiv tso pa roj tawm hauv cov txheej nruab nrab ntawm lub tshuab nqus tsev, maj mam txo qhov nqus tsev ntawm cov txheej nruab nrab ntawm lub tshuab nqus tsev. Yog li ntawd, VI yeeb nkab muaj lub neej ua haujlwm ib txwm muaj. Thaum qhov nqus tsev poob qis mus rau qhov tsis tuaj yeem ua adiabatic, VI yeeb nkab tuaj yeem raug nqus tsev rau zaum ob los ntawm lub tshuab twj kom txhim kho qhov nqus tsev thiab rov qab ua kom nws cov txiaj ntsig rwb thaiv tsev zoo dua.

Kev ua kom khov tsis txaus lub tshuab nqus tsev, thiab dej puas txaus thiab?

Thaum qhov tshwm sim ntawm kev tsim dej tshwm sim hauv lub raj xa dej adiabatic, qhov degree nqus tsev tsis tas yuav tsis txaus.

Ua ntej tshaj plaws, qhov cuam tshuam ntawm cov yeeb nkab VI yog qhov sib piv. Thaum qhov kub ntawm phab ntsa sab nraud ntawm cov yeeb nkab VI qis dua qhov kub ib puag ncig hauv 3 Kelvin (sib npaug rau 3 ℃), qhov zoo ntawm cov yeeb nkab VI raug suav hais tias txais tau. Yog li ntawd, yog tias qhov av noo ib puag ncig siab heev thaum lub sijhawm ntawd, thaum qhov kub ntawm cov yeeb nkab VI tsawg dua 3 Kelvin los ntawm ib puag ncig, qhov xwm txheej dej condensation kuj yuav tshwm sim. Cov ntaub ntawv tshwj xeeb tau qhia hauv daim duab hauv qab no.

Piv txwv li, thaum qhov av noo ib puag ncig yog 90% thiab qhov kub ib puag ncig yog 27 ℃, qhov kub tseem ceeb ntawm kev tsim dej lub sijhawm no yog 25.67 ℃. Uas yog hais tias, thaum qhov sib txawv ntawm qhov kub ntawm VI yeeb nkab thiab ib puag ncig yog 1.33 ℃, qhov tshwm sim ntawm dej condensation yuav tshwm sim. Txawm li cas los xij, qhov sib txawv ntawm qhov kub ntawm 1.33 ℃ yog nyob rau hauv qhov ntau ntawm cov yeeb nkab VI, yog li nws tsis yooj yim sua kom txhim kho qhov xwm txheej ntawm dej condensation los ntawm kev txhim kho qhov zoo ntawm VI yeeb nkab.

Lub sijhawm no, peb xav kom ntxiv cov khoom siv dehumidification, qhib lub qhov rais rau qhov cua, thiab txo cov av noo ib puag ncig, kom zoo dua qhov xwm txheej dej condensation.
