Imowudi nganye yodluliselo ichaphazela ukusebenza kwamandla ngokupheleleyo. Ubuchwephesha bobunjineli obuphezulu bujolise kuzo zontathu iindlela zokunciphisa ukuhanjiswa kwe-thermal ngokupheleleyo.
Ixabiso lika-U vs. Ixabiso le-R
Abaninimzi abaninzi baqaphela amaxabiso e-R asuka kwiimveliso eziqhelekileyo zokugquma ekhaya. Ixabiso le-R lilinganisa ukuxhathisa kwe-thermal, ebonisa ukukwazi kwezinto eziphathekayo ukuthintela ukuhamba kobushushu. Ngokuchaseneyo, ixabiso le-U lilinganisa ukuhanjiswa kwe-thermal, ebonisa ukuhamba lula kobushushu kwindibano.
I-Key takeaway: Ixabiso le-R kunye nomsebenzi wexabiso le-U njengeenguqu zemathematika ezichazwe kuchazo $U = rac{1}{R}$.
Metric / Ubudlelwane | Ifomula | Umzekelo wokubala |
|---|---|---|
Ubudlelwane beMathematika | IiReciprocals zeMathematika / Ukuchasana | $U = rac{1}{R}$ okanye $R = rac{1}{U}$ |
Guqula i-U-Xabiso ukuya kwi-R-Value | $R = rac{1}{U}$ | Ixabiso le-U ye-$0.10 \utolo olusekunene R = \frac{1}{0.10} = 10$ |
Guqula i-R-Value ukuya kwi-U-Value | $U = rac{1}{R}$ | Ixabiso le-R ye-$3.45 \utolo lwasekunene U = \frac{1}{3.45} \malunga ne-0.29$ |
Ukuqonda olu lwalamano luphambeneyo kunceda abakhi bakhethe okulungileyo Ifestile ye-Energy Effective yobuninzi benduduzo yangaphakathi kunye nolawulo lwemozulu.
Kutheni i-U-Values ibalulekile kwi-Energy Effective Window Performance
Iindibano zefestile zibonisa amaxabiso e-U aqhelekile phakathi kwe-0.20 kunye ne-1.20. Amanqaku asezantsi adlala indima ebalulekileyo kwiindawo ezibandayo zemozulu kuba anqanda ubushushu obuxabisekileyo bangaphakathi ukuba bubaleke. Ukuqonda la manani kunceda abathengi bakhethe iifestile ezilawula ukuhanjiswa kwe-thermal ngokufanelekileyo unyaka wonke.
Ukuthoba Iindleko zokufudumeza kunye nokuPholisa
Ukuhanjiswa kwe-thermal esezantsi kunciphisa ngokuthe ngqo umthwalo womsebenzi we-HVAC. Xa iifestile zivala ukuhamba kwe-thermal engafunwayo, iinkqubo zokufudumeza kunye nokupholisa zihamba ngaphantsi rhoqo. Oku kusebenza kakuhle kuguqulela ukonga amandla enyanga kwaye kuthoba icarbon footprint yesakhiwo. Ukukhetha i Ifestile yokuSebenza kwamandla igcina ubushushu bomoya wangaphakathi buzinzile ngaphandle kokubeka uxinzelelo olongezelelweyo kwisixhobo.
Nangona kunjalo, ixabiso le-U lixelela kuphela isiqingatha sebali le-thermal. Iingcali zokwakha zivavanya ixabiso le-U ecaleni kwe-Solar Heat Gain Coefficient (SHGC) ukubala i-thermal dynamics epheleleyo.
