Lithini ixabiso le-U kwiimveliso zokugquma ubushushu?

Ixabiso le-U, elikwabizwa ngokuba yi-U-factor, liyimilinganiselo ebalulekileyo kwintsimi yeemveliso zokufakelwa kwe-thermal.Imele isantya apho ubushushu bugqithiselwa khona ngezinto eziphathekayo.Ixabiso eliphantsi le-U, ngcono ukusebenza kwe-insulation yemveliso.Ukuqonda ixabiso le-U lemveliso yokugquma kubalulekile ekwenzeni izigqibo ezizizo malunga nokusebenza kwamandla kunye nokukhululeka kwesakhiwo.

Xa kuqwalaselwa imveliso yokugquma, kubalulekile ukuqonda ixabiso layo le-U ukuvavanya ukusebenza kwayo ekuthinteleni ukulahleka kobushushu okanye ukufumana.Oku kubaluleke ngakumbi kwishishini lokwakha, apho ukusebenza kombane kunye nokuzinza kuyingqwalasela ephambili.Ngokukhetha iimveliso ezinexabiso eliphantsi le-U, abakhi kunye nabanikazi bezindlu banokunciphisa ukusetyenziswa kwamandla kunye nokunciphisa iindleko zokufudumeza kunye nokupholisa.

Ixabiso le-U leemveliso zokugquma lichatshazelwa zizinto ezifana nohlobo lwemathiriyeli, ubukhulu, kunye nobuninzi.Umzekelo, izixhobo ezinje nge-fiberglass, i-cellulose, kunye nokufakwa kwe-foam zinexabiso elahlukileyo le-U ngenxa ye-thermal conductivity eyahlukeneyo.Ukongezelela, ukwakhiwa kunye nokufakwa kwe-insulation kuya kuchaphazela ixabiso layo lonke le-U.

Ukumisela ixabiso le-U yemveliso ethile yokugquma, umntu kufuneka abhekisele kwiinkcukacha zobugcisa ezinikezelwe ngumenzi.Ezi nkcukacha ziquka ixabiso le-U, elichazwe kwiiyunithi ze-W/m²K (i-Watts nge-square meter nganye nge-Kelvin).Ngokuthelekisa ixabiso le-U yeemveliso ezahlukeneyo, abathengi banokwenza ukhetho olunolwazi malunga nokuba yeyiphi imathiriyeli yokugquma ezilungele iimfuno zabo.

Isishwankathelo, ixabiso le-U lemveliso yokugquma lidlala indima ebalulekileyo ekuvavanyeni ukusebenza kwayo kwe-thermal.Ngokuqonda kunye nokuqwalasela amaxabiso e-U xa ukhetha izinto zokugquma, abantu kunye namashishini banokufaka isandla ekongeni amandla kunye nokudala ubomi obutofotofo ngakumbi kunye nozinzo kunye neendawo zokusebenza.Kubalulekile ukubeka phambili iimveliso ezinamaxabiso aphantsi e-U ukuze usebenze ngokufanelekileyo kwamandla kunye nokukhululeka kwe-thermal.
