Ingakanani inani lemikhiqizo yokushisa e-U?

Inani le-U, elaziwa nangokuthi i-U-factor, liyisilinganiso esibalulekile emkhakheni wemikhiqizo yokushisa. Limelela izinga lokushisa elidluliselwa ngalo ngezinto. Uma inani le-U liphansi, kulapho ukusebenza kokushisa komkhiqizo kuba ngcono khona. Ukuqonda inani le-U lomkhiqizo wokushisa kubalulekile ekwenzeni izinqumo ezinolwazi mayelana nokusebenza kahle kwamandla kwesakhiwo kanye nenduduzo.

Uma ucabangela umkhiqizo wokuvikela ukushisa, kubalulekile ukuqonda inani lawo le-U ukuze uhlole ukusebenza kwawo ekuvimbeleni ukulahleka noma ukukhuphuka kokushisa. Lokhu kubaluleke kakhulu embonini yokwakha, lapho ukusebenza kahle kwamandla kanye nokusimama kuyizinto ezibalulekile okufanele uzicabangele. Ngokukhetha imikhiqizo enamanani aphansi e-U, abakhi kanye nabanini bezindlu banganciphisa ukusetshenziswa kwamandla futhi banciphise izindleko zokushisa nokupholisa.

Inani le-U lemikhiqizo yokuvikela ukushisa lithinteka yizici ezifana nohlobo lwezinto ezibonakalayo, ukujiya, kanye nobuningi. Isibonelo, izinto ezifana ne-fiberglass, i-cellulose, kanye nokuvikela ukushisa kwe-foam zinamanani e-U ahlukene ngenxa yokuguquguquka kokushisa okuhlukile. Ngaphezu kwalokho, ukwakhiwa nokufakwa kokuvikela ukushisa kuzothinta inani layo le-U lilonke.

Ukuze kunqunywe inani le-U lomkhiqizo othize wokufaka izinto zokushisa, umuntu kufanele abheke imininingwane yobuchwepheshe enikezwe umenzi. Lezi zincazelo zivame ukufaka inani le-U, elivezwa ngamayunithi e-W/m²K (ama-Watts ngemitha yesikwele ngayinye ye-Kelvin). Ngokuqhathanisa amanani e-U emikhiqizo ehlukene, abathengi bangenza ukukhetha okunolwazi mayelana nokuthi iyiphi into yokufaka izinto zokushisa efanelana nezidingo zabo.

Ngamafuphi, inani le-U lomkhiqizo wokufaka izinto zokushisa lidlala indima ebalulekile ekuhloleni ukusebenza kwawo kokushisa. Ngokuqonda nokucabangela amanani e-U lapho ukhetha izinto zokufaka izinto zokushisa, abantu ngabanye kanye namabhizinisi bangafaka isandla ekongeni amandla futhi bakhe izindawo zokuhlala nezokusebenza ezikhululekile nezisimeme. Kubalulekile ukubeka phambili imikhiqizo enamanani e-U aphansi ukuze kusetshenziswe kahle amandla kanye nenduduzo yokushisa.
