Iyini i-thermal conductivity ye-insulation?

I-Thermal conductivity, eyaziwa nangokuthi i-thermal conductivity, iyisici esibalulekile esinquma umphumela wokushisa wezakhiwo.Ikala ikhono lempahla lokuqhuba ukushisa futhi iwukucatshangelwa okubalulekile lapho kukhethwa izinto zokwakha ukufakwa kwe-insulation.Ukuqonda ukuthi i-thermal conductivity ye-insulation ingasiza abanikazi bezindlu nabakhi ukuthi benze izinqumo ezinolwazi mayelana nohlobo olungcono kakhulu lwe-insulation okufanele lusetshenziswe ezindlini zabo.

I-Thermal conductivity isilinganiso sekhono lempahla lokuqhuba ukushisa.Ivezwa ngama-watt imitha ngedigri Celsius (W/mK) futhi ibonisa izinga lokushisa okudluliselwa ngalo ngento ethile.Izinto ezine-conductivity ephansi ye-thermal zingama-insulators angcono ngoba zihambisa ukushisa kancane kahle.

Uma kukhulunywa ngokufakwa kwe-thermal, i-thermal conductivity idlala indima ebalulekile ekunqumeni ikhono lempahla lokugcina isakhiwo sifudumele ebusika futhi sipholile ehlobo.I-insulation isebenza ngokubamba amaphakethe omoya ngaphakathi kwesakhiwo sayo, okwenza umgoqo obambezela ukudluliswa kokushisa.Izinto ezine-conductivity ephansi ye-thermal zivimbela ngempumelelo ukushisa ekuphumeni noma ukungena esakhiweni, ukunciphisa izindleko zamandla nokuthuthukisa ukunethezeka kwabahlali.

I-thermal conductivity yezinto zokufakelwa ingahluka kuye ngohlobo lwezinto ezisetshenzisiwe.Isibonelo, i-fiberglass ne-cellulose insulation ine-thermal conductivities engaba ngu-0.04-0.05 W/mK, kuyilapho ukufakwa kwegwebu lesifutho kungase kube ne-thermal conductivities ephansi njengo-0.02 W/mK.Ngenxa ye-conductivity ephansi yokushisa, lezi zinto zibhekwa njengama-insulators asebenzayo.

Lapho ukhetha uhlobo olufanele lokufakelwa kwesakhiwo, kubalulekile ukuqonda ukuqhutshwa kokushisa kwe-insulation.Izici ezifana nesimo sezulu, umklamo wesakhiwo kanye nezinto ezithandwa umuntu ngamunye zidlala indima ekunqumeni ukuthi iyiphi into engcono kakhulu yokwahlukanisa.Lapho ukhetha inketho efanelekile kakhulu yesakhiwo esithile, kubalulekile ukucabangela inani le-R le-insulation material kanye ne-thermal conductivity.

Ezimweni ezibandayo, lapho izindleko zokushisisa ziyinkinga, kubalulekile ukukhetha izinto zokufakelwa ezine-conductivity ephansi yokushisa ukuze unciphise ukulahlekelwa ukushisa.Ezimweni ezifudumele, ukugxila kungase kube ekuvimbeleni ukuzuza ukushisa, ngakho-ke ukwahlukanisa okune-conductivity ephansi ye-thermal kubaluleke ngokufanayo.Ngokuqonda i-thermal conductivity of insulation, abanikazi bezindlu nabakhi bangakhetha ukufakwa okuphumelelayo kakhulu ngokusekelwe ezidingweni zabo ezithile.

Kafushane, i-thermal conductivity ye-insulating material iyisici esibalulekile ekunqumeni ikhono lezinto zokumelana nokudluliselwa kokushisa.Izinto ezine-thermal conductivity ephansi zingama-insulators angcono, asiza ukuthuthukisa ukusebenza kahle kwamandla nokunethezeka kwesakhiwo.Ngokuqonda ukuguquguquka okushisayo kwe-insulation kanye nokubaluleka kwakho, abanikazi bezindlu nabakhi bangenza izinqumo ezinolwazi mayelana nohlobo olungcono kakhulu lokugqumisa okufanele balusebenzise ezindlini zabo.
