Yintoni i-thermal conductivity ye-insulation?

I-Thermal conductivity, eyaziwa ngokuba yi-thermal conductivity, yinto ephambili eyenza i-insulation effect yezakhiwo. Ilinganisa amandla okwenza ubushushu kwaye ibaluleke kakhulu xa ukhetha izinto zokwakha. Ukuqonda i-thermal conductivity ye-insulation kunokunceda abanini bezindlu kunye nabakhi benze izigqibo ezinolwazi malunga nolona hlobo lungcono lokugquma olunokusetyenziswa kumakhaya abo.

I-Thermal conductivity ngumlinganiselo wezinto eziphathekayo zokuqhuba ubushushu. Ibonakaliswa ngee-watts ngemitha ngeqondo leCelsius (W/mK) kwaye ibonakalisa isantya sokuhanjiswa kobushushu ngesixhobo. Izinto eziphathekayo ezine-conductivity ephantsi ye-thermal zi-insulators ezingcono kuba ziqhuba ukushisa ngaphantsi ngokufanelekileyo.

Xa kuziwa kwi-thermal insulation, i-thermal conductivity idlala indima ebalulekileyo ekunqumeni ukukwazi kwezinto eziphathekayo ukugcina isakhiwo sifudumele ebusika kwaye sipholile ehlotyeni. I-Insulation isebenza ngokubambisa iipokethi zomoya ngaphakathi kwesakhiwo sayo, ukudala umqobo obambezela ukuhanjiswa kobushushu. Izinto eziphathekayo ezine-conductivity ephantsi ye-thermal zithintela ngokufanelekileyo ukushisa ekuphumeni okanye ukungena kwisakhiwo, ukunciphisa iindleko zamandla kunye nokuphucula induduzo yabahlali.

I-Thermal conductivity ye-insulation materials ingahluka ngokuxhomekeke kuhlobo lwezinto ezisetyenzisiweyo. Ngokomzekelo, i-fiberglass kunye ne-cellulose insulation ine-thermal conductivities malunga ne-0.04-0.05 W / mK, ngelixa i-spray foam insulation ingaba ne-thermal conductivities ephantsi kwe-0.02 W / mK. Ngenxa ye-conductivity ephantsi ye-thermal, ezi zixhobo zibhekwa njenge-insulators ezisebenzayo.

Xa ukhetha uhlobo olufanelekileyo lokufakelwa kwesakhiwo, kubalulekile ukuqonda i-insulation conductivity ye-thermal conductivity. Izinto ezinje ngemozulu, uyilo lwesakhiwo kunye nokhetho lomntu zonke zidlala indima ekumiseleni eyona mathiriyeli igqwesileyo yokugquma. Xa ukhetha ukhetho olufanelekileyo kwisakhiwo esithile, kubalulekile ukuqwalasela i-R-value ye-insulation material kunye ne-thermal conductivity.

Kwiindawo ezibandayo, apho iindleko zokufudumeza zingumcimbi, kubalulekile ukukhetha izinto zokugquma nge-conductivity ephantsi ye-thermal ukunciphisa ukulahleka kobushushu. Kwiimozulu ezifudumeleyo, kugxininiswa ekuthinteleni ukufudumala kobushushu, ngoko ke ukugquma nge-conductivity ephantsi ye-thermal kubaluleke ngokulinganayo. Ngokuqonda i-thermal conductivity ye-insulation, abanini bezindlu kunye nabakhi banokukhetha i-insulation eyona nto isebenzayo ngokusekelwe kwiimfuno zabo ezithile.

Isishwankathelo, i-thermal conductivity ye-insulating material iyona nto ibalulekileyo ekunqumeni ukukwazi ukuchasana nokuhanjiswa kobushushu. Izinto eziphathekayo ezine-conductivity ephantsi ye-thermal zi-insulators ezingcono, ezinceda ukuphucula amandla okusebenza kunye nokuthuthuzela kwesakhiwo. Ngokuqonda i-thermal conductivity ye-insulation kunye nokubaluleka kwayo, abanini bezindlu kunye nabakhi banokwenza izigqibo ezinolwazi malunga nolona hlobo lungcono lokufakela ukusetyenziswa kumakhaya abo.
