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 ezinokusebenza okuphansi kwe-thermal zivimbela ngempumelelo ukushisa ukuthi kungaphumi noma kungene esakhiweni, kunciphisa izindleko zamandla futhi kuthuthukise 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 impahla yokushisa engcono kakhulu. 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.
