Iyini inani lika-U lemikhiqizo yokufakwa kwe-thermal?

I-U-value, eyaziwa nangokuthi i-U-factor, iyisilinganiso esibalulekile emkhakheni wemikhiqizo ye-thermal insulation. Imele izinga lokushisa okudluliselwa ngalo ngento ethile. Lapho i-U-valu iphansi, kuba ngcono ukusebenza kokufakwa komkhiqizo. Ukuqonda inani le-U lomkhiqizo wokufakwa ngaphakathi kubalulekile ekwenzeni izinqumo ezinolwazi mayelana nokusebenza kahle kwamandla nokunethezeka kwesakhiwo.

Uma ucubungula umkhiqizo wokufakwa ngaphakathi, kubalulekile ukuqonda inani le-U ukuze uhlole ukusebenza kahle kwawo ekuvimbeleni ukulahlekelwa ukushisa noma ukuzuza. Lokhu kubaluleke kakhulu embonini yezokwakha, lapho ukonga kwamandla kanye nokusimama kuyizinto ezicatshangelwayo ezibalulekile. Ngokukhetha imikhiqizo enamanani aphansi e-U, abakhi nabanikazi bezindlu banganciphisa ukusetshenziswa kwamandla futhi banciphise izindleko zokushisisa nokupholisa.

I-U-value yemikhiqizo yokufakelwa ithintwa izici ezifana nohlobo lwempahla, ukujiya, kanye nokuminyana. Isibonelo, izinto ezifana ne-fiberglass, i-cellulose, kanye nokufakwa kwegwebu kunamanani e-U ahlukene ngenxa ye-thermal conductivity ehlukene. Ukwengeza, ukwakhiwa nokufakwa kwe-insulation kuzothinta inani layo le-U lilonke.

Ukuze unqume inani le-U lomkhiqizo othile wokufakelwa, umuntu kufanele abhekisele kumininingwane yobuchwepheshe enikezwe umenzi. Lezi zicaciso ngokuvamile zihlanganisa inani le-U, elivezwa ngamayunithi we-W/m²K (Ama-Watts ngemitha yesikwele nge-Kelvin ngayinye). Ngokuqhathanisa amanani e-U emikhiqizo ehlukene, abathengi bangenza ukukhetha okunolwazi mayelana nokuthi iyiphi impahla yokufaka evumelana kangcono nezidingo zabo.

Kafushane, inani le-U lomkhiqizo wokufakwa ngaphakathi lidlala indima ebalulekile ekuhloleni ukusebenza kwawo okushisayo. Ngokuqonda futhi ucabangele amanani e-U lapho kukhethwa izinto zokufakelwa, abantu ngabanye namabhizinisi bangaba neqhaza ekongeni amandla futhi badale indawo yokuhlala enethezekile nesimeme kanye neyokusebenzela. Kubalulekile ukubeka phambili imikhiqizo enamanani aphansi we-U ukuze uthole ukusebenza kahle kwamandla nokunethezeka kokushisa.
