Qhov sib txawv tseem ceeb ntawm cov dej lwg thiab qhov dej khov yog qhov dej lwg taw tes yog qhov kub ntawm cov huab cua los ua cov dej vapor, qhov chaw khov yog qhov kub ntawm cov kua ua kua.
Dew point thiab khov taw tes yog qhov tseem ceeb analytical tsis. Cov tsis muaj lossis cov ntsiab lus no sawv cev rau qhov kub thiab txias uas qee qhov kev hloov pauv rau theem teeb meem tshwm sim.
Dew Point yog dab tsi?
Dewpoint kub yog qhov kub uas cov huab cua nkag mus nrog dej vapor. Hauv lwm lo lus, nws yog qhov kub thiab txias uas peb yuav tsum txias huab cua kom saturate cov huab cua nrog dej vapor. Yog li ntawd, thaum txias ntxiv, dej vapor pib condense thiab tsim dew drops. Tab sis thaum qhov kub thiab txias qis dua qhov dej khov, ces peb hu lub dewpoint "tej dej khov" vim tias nyob rau qhov kub no, Frost, tsis yog dew, tsim.
Thaum lub dewpoint kub sib npaug ntawm huab cua kub, nws yog lub xeev ntawm saturation ntawm huab cua nrog dej vapor. Tab sis qhov kub no yeej tsis tshaj qhov cua kub. Yog li ntawd, yog tias huab cua zoo li txias dua, noo noo yuav raug tshem tawm ntawm huab cua los ntawm condensation.
Thaum xav txog kev sib raug zoo ntawm tus txheeb ze av noo thiab dewpoint;
- Yog qhov dew point ze rau qhov kub ntawm huab cua qhuav, qhov txheeb ze av noo siab.
- Yog tias qhov dewpoint zoo hauv qab qhov cua qhuav, qhov txheeb ze av noo qis.
Dab tsi yog qhov taw qhia khov?
Qhov chaw khov yog qhov kub ntawm cov kua ua kua. Ntawm qhov chaw khov, cov kua mus rau cov khoom hloov pauv ntawm cov theem ntawm cov teeb meem tshwm sim ntawm lub melting point, thiab cov khoom theem hloov mus rau hauv nws cov theem ua kua. Raws li txoj cai, lub freezing point yog sib npaug rau lub melting point. Tab sis kev xyaum, peb tuaj yeem ua kua dej txias tshaj qhov chaw khov.
Peb tuaj yeem siv cov ntsiab lus khov thiab khov kho sib hloov, tab sis qee qhov zoo li sib txawv ntawm ob nqe lus no vim tias khov khov tshwm sim vim qhov hloov pauv ntawm qhov kub thiab txias, thaum khov tuaj yeem tshwm sim vim kev hloov pauv hauv siab ib yam.
Paub qhov khov ntawm cov ntaub ntawv tseem ceeb heev hauv kev siv sib txawv. Piv txwv li, hauv kev khaws zaub mov, qhov twg peb tuaj yeem cuam tshuam cov khoom noj thiab kev loj hlob ntawm cov kab mob, nrog rau kev khov ntawm cov kab mob nyob lossis cov ntaub so ntswg thaum khaws cov ntaub so ntswg.
Dab tsi yog qhov txawv ntawm Dew Point thiab Freezing Point?
Dew point thiab khov taw tes yog qhov tseem ceeb analytical tsis. Qhov sib txawv tseem ceeb ntawm qhov dew point thiab qhov chaw khov yog qhov dej lwg taw tes yog qhov kub ntawm qhov cua uas cov huab cua nkag mus rau hauv cov dej vapor, qhov chaw khov yog qhov kub ntawm cov kua ua kua.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm cov dej lwg taw tes thiab qhov chaw khov rau hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Dew Point vs Freezing Point
Dew point thiab khov taw tes yog qhov tseem ceeb analytical tsis. Cov tsis muaj lossis cov ntsiab lus no sawv cev rau qhov kub thiab txias uas qee qhov kev hloov pauv rau theem teeb meem tshwm sim. Qhov sib txawv tseem ceeb ntawm qhov dew point thiab qhov chaw khov yog qhov dej lwg taw tes yog qhov kub ntawm cov huab cua los ua cov dej vapor, qhov chaw khov yog qhov kub ntawm cov kua ua kua. Piv txwv li, lub freezing point yog siab dua nyob rau hauv qhov kub thiab txias tshaj lub dew point. Nws yog qhov tseeb tseem ceeb hauv nag lossis daus loj hlob hauv huab.
