Momwe mungasankhire galasi yoyenera yopulumutsa mphamvu m'madera osiyanasiyana a nyengo?

Pali mitundu yambiri ya galasi pamsika, kuwonjezera pa kumvetsera kwambirichitetezo ntchito galasi, maso a anthu ambiri amayang'ananso pakupulumutsa mphamvu ya galasi, tiyeni timvetsetse momwe tingasankhire galasi loyenera kuyika ndikugwiritsa ntchito m'madera osiyanasiyana a nyengo?

Magawo opulumutsa mphamvu a galasi ali ndi ziwonetsero ziwiri, mtengo wa mthunzi wa SC ndi mtengo wotengera kutentha kwa K, zomwe mwazizindikiro ziwirizi zomwe zimaperekedwa pakupulumutsa mphamvu zomanga zimadalira nyengo yanyumbayo, komanso zimadalira nyengo yanyumbayo. pakugwiritsa ntchito ntchito yomanga.

SC: Shading Coefficient, yomwe imatanthawuza chiyerekezo cha kuchuluka kwa magalasi agalasi mpaka 3mm.muyezo mandala galasi. (Theoretical value of GB/T2680 is 0.889, and international standard is 0.87) powerengera, SC=SHGC÷0.87 (kapena 0.889). Monga momwe dzinalo likusonyezera, ndikutha kwa galasi kutsekereza kapena kukana mphamvu ya dzuwa, ndipo mthunzi wa SC mtengo wa galasi umasonyeza kutentha kwa ma radiation a dzuwa kudzera mu galasi, kuphatikizapo kutentha kupyolera mu kuwala kwa dzuwa ndi kutentha. amawotchera kuchipinda galasi litatenga kutentha. Kutsika kwa SC kumatanthauza kuti mphamvu zochepa za dzuwa zimawululidwa kudzera mugalasi.

K mtengo: ndi gawo lotengera kutentha kwa gawo lagalasi, chifukwa cha kutentha kwa galasi komanso kusiyana kwa kutentha kwamkati ndi kunja, mpweya wopangidwa ndi kutentha kwa mpweya. Magawo ake aku Britain ndi awa: ma unit otentha aku Britain pa phazi lalikulu pa ola pa Fahrenheit. Pansi pa zinthu muyezo, pansi wina kutentha kusiyana pakati pa mbali ziwiri za vakuyumu galasi, kutentha anasamutsa mbali ina pa unit nthawi kudzera unit dera. Ma metric mayunitsi a K mtengo ndi W /㎡·K. Coefficient yotengera kutentha sikungokhudzana ndi zinthu, komanso ndondomeko yeniyeni. Kuyesa kwa mtengo wa K waku China kumatengera muyeso waku China wa GB10294. Kuyesa kwa mtengo wa European K kumachokera ku European EN673 standard, ndipo kuyesa kwa American U value kumachokera ku American ASHRAE standard, ndipo American ASHRAE standard imagawaniza miyeso ya U value mu nyengo yachisanu ndi chilimwe.

Zomangamanga zosungira mphamvu zopangira mphamvu zimapereka chilolezo chochepetsera zitseko ndi Windows kapenagalasi chophimbamakoma malinga ndi nyengo zosiyanasiyana. Pansi pamalingaliro oti akwaniritse index iyi, galasi lokhala ndi shading coefficient SC yotsika liyenera kusankhidwa m'malo omwe kugwiritsa ntchito mphamvu zowongolera mpweya kumakhala kokulirapo. Mwachitsanzo, m'madera omwe ali ndi chilimwe chotentha komanso nyengo yozizira, kafukufuku amasonyeza kuti mphamvu zomwe zimagwiritsidwa ntchito chifukwa cha kuwala kwa dzuwa zimakhala pafupifupi 85% ya mphamvu zomwe zimagwiritsidwa ntchito pachaka m'derali. Kugwiritsa ntchito mphamvu kwa kusiyana kwa kutentha kwa kutentha kumakhudza 15% yokha, kotero n'zoonekeratu kuti derali liyenera kukulitsa mthunzi kuti lipeze mphamvu yopulumutsa mphamvu.

Madera omwe ali ndi gawo lalikulu la kutentha kwamagetsi ayenera kusankha magalasi okhala ndi kutentha kochepa, monga madera ozizira okhala ndi nthawi yochepa yachilimwe, nthawi yayitali yozizira komanso kutentha kwakunja kwakunja, kutsekemera kwakhala kutsutsana kwakukulu, ndipo mtengo wotsika wa K ndiwothandiza kwambiri. kupulumutsa mphamvu. Ndipotu, ziribe kanthu dera la nyengo, kutsika kwa mtengo wa K ndikosakayikitsa bwino, koma kuchepetsa mtengo wa K ndi mtengo, ngati kuwerengera gawo laling'ono la zopereka zopulumutsa mphamvu siziyenera kutsata, ndithudi, kuchita. osapereka ndalama kwaulere.

Titha kunena kuti kutsika kwa mtengo wa K, kumapangitsanso kuti ntchito yotsekera bwino, komanso kuthandizira kwake pakusunga mphamvu kumachepa pang'onopang'ono kuchokera kumpoto kupita kumwera, ndipo ngati ikufunika kutsika imatha kuganiziridwa molingana ndi zomwe mtengo wake umatengera. kukwaniritsa zofunikira za miyezo yosunga mphamvu. M'munsi mwa shading coefficient SC ndi, ndizopindulitsa kupulumutsa mphamvu m'chilimwe, koma zovulaza kupulumutsa mphamvu m'nyengo yozizira. Pali zotsutsa zambiri ngati nyumba zogona m'madera otentha ndi ozizira komanso nyumba za anthu m'madera ozizira ziyenera kukhala zowonjezera dzuwa, zomwe zingathe kufufuzidwa molingana ndi ntchito ya nyumbayo, ndipo ubwino wake ukuposa kuipa kwake.

Ngakhale kutsika kwa mtengo wa SC, kulimba kwa mphamvu ya dzuwa, kumapangitsanso ntchito yabwino yotsekereza kutentha kwa dzuwa kuchipinda. Komabe, ngati mutsatira mwachimbulimbuli kutsika kwa mtengo wa SC, kuwala kocheperako, kuyatsa kochepa m'nyumba, galasi lakuda kwambiri. Choncho, tiyenera kuganizira ophatikizana zotsatira zakuyatsa, kukula,phokosondi zina kuti apeze galasi lawo lopulumutsa mphamvu.
