Kodi mphamvu ya kukana kwa mpweya wa madzi ndi chiyani pakugwira ntchito kwa zida zotchinjiriza?

Kugwira ntchito kwa zida zotenthetsera kutentha ndizofunikira kwambiri pakupanga mapangidwe ndi mphamvu zamagetsi. Zina mwazinthu zambiri zomwe zimakhudza magwiridwe antchito a kutchinjiriza, kuchuluka kwa mpweya wotulutsa madzi (μ) kumagwira ntchito yofunika kwambiri. Kumvetsetsa momwe coefficient iyi imakhudzira zida zotsekera kumathandizira kupanga zosankha zabwino zazinthu, potero kumapangitsa ntchito yomanga.

Mphamvu yolimbana ndi mpweya wamadzi (yomwe nthawi zambiri imatanthauzidwa ndi μ) ndi chizindikiro cha kuthekera kwa chinthu kukana kupita kwa nthunzi wamadzi. Amatanthauzidwa ngati chiŵerengero cha kukana kwa mpweya wa madzi kwa zinthu zomwe zimagwiritsidwa ntchito (nthawi zambiri mpweya). Mtengo wapamwamba wa μ umasonyeza kukana kwakukulu kwa kufalikira kwa chinyezi; mtengo wotsika μ umasonyeza kuti zinthuzo zimalola kuti chinyezi chochuluka chidutse.

Chimodzi mwazinthu zazikulu zomwe zimakhudzidwa ndi kukana kwa mpweya wamadzi pazida zotchinjiriza ndi mphamvu yake pakuwongolera chinyezi mkati mwazomangamanga. Zipangizo zothirira zokhala ndi mpweya wochuluka wa madzi (μ mtengo) zimalepheretsa chinyezi kulowa muzitsulo zotsekera, zomwe ndizofunikira kuti zisungidwe bwino. Zida zosungunulira zikakhala zonyowa, kukana kwawo kwamafuta kumachepa kwambiri, zomwe zimapangitsa kuti pakhale mphamvu zowonjezera pakuwotcha kapena kuziziritsa. Chifukwa chake, kusankha zida zotchinjiriza zokhala ndi mphamvu yolimbana ndi nthunzi yamadzi yoyenera (μ mtengo) ndikofunikira kuti zitsimikizire kuti zimagwira ntchito bwino pakanthawi yayitali.

Kuphatikiza apo, mphamvu yolimbana ndi nthunzi yamadzi imakhudzanso chiwopsezo cha condensation mkati mwazomangamanga. M'madera omwe ali ndi chinyezi chambiri kapena madera omwe ali ndi kusiyana kwakukulu kwa kutentha, chinyezi chimakhazikika pamalo ozizira. Zipangizo zotsekemera zokhala ndi madzi otsika (μ mtengo) zitha kulola kuti chinyezi chilowe m'chigawocho ndikulowa mkati, zomwe zimapangitsa kuti pakhale zovuta monga kukula kwa nkhungu, kuwonongeka kwamapangidwe, komanso kuchepa kwa mpweya wamkati. Mosiyana ndi zimenezi, zipangizo zokhala ndi madzi apamwamba zimatha kuchepetsa zoopsazi poletsa kutuluka kwa chinyezi, potero kumapangitsa kuti mavulopu apangidwe azikhala olimba komanso akugwira ntchito.

Posankha zida zotchinjiriza, mawonekedwe ogwiritsira ntchito ndi momwe chilengedwe chikuyenera kuganiziridwa. Mwachitsanzo, m'madera ozizira kumene chiopsezo cha condensation ndi chachikulu, tikulimbikitsidwa kugwiritsa ntchito zipangizo zotetezera ndi mpweya wochuluka wa madzi otsekemera. Izi zimathandiza kuti insulation ikhale yowuma komanso kuti insulation ikhale yogwira ntchito. Kumbali ina, m'madera otentha ndi amvula, kusinthanitsa kuyenera kuchitidwa. Ngakhale kukana chinyezi kumafunika, kuchuluka kwa madzi ochulukirapo (μ mtengo) kumatha kupangitsa kuti chinyezi chikhalebe mkati mwa khoma, zomwe zimayambitsa mavuto ena. Chifukwa chake, kumvetsetsa nyengo yakumaloko komanso zosowa zenizeni za nyumbayo ndikofunikira posankha zida zotsekera.

Kupatula kuwongolera chinyezi, mphamvu yolimbana ndi mpweya wamadzi imakhudzanso mphamvu zonse zanyumba. Kusankha zida zoyenera zotchinjiriza ndikuwongolera bwino chinyezi kumatha kuchepetsa mtengo wamagetsi, kuwongolera chitonthozo, ndikuwongolera mpweya wabwino wamkati. Izi ndizofunikira makamaka pamamangidwe okhazikika, pomwe mphamvu zogwiritsira ntchito mphamvu ndi chilengedwe ndizofunikira kwambiri.

Mwachidule, kukana kufalikira kwa nthunzi wamadzi ndi chinthu chofunikira kwambiri pakuwunika momwe zida zotetezera kutentha zimagwirira ntchito. Kukhudza kwake pakuwongolera chinyezi, kuwopsa kwa condensation, komanso kuwongolera mphamvu zonse kumatsimikizira kufunikira kosankha mosamala zinthu pomanga nyumba. Pomvetsetsa ndi kugwiritsa ntchito mfundo za kukana kufalikira kwa mpweya wa madzi, omanga mapulani, makontrakitala, ndi eni ake amatha kupanga zisankho zanzeru zomanga nyumba zolimba, zogwira mtima komanso zabwino. Pamene ntchito yomanga ikupitabe patsogolo, kuphatikiza njira zowongolera chinyezi kudzakhalabe gawo lofunikira kwambiri pakukwaniritsa njira zotsekera zogwira ntchito kwambiri.
