Gusobanukirwa isano ya K-Agaciro, U-Agaciro na R-Agaciro mubicuruzwa byigenga bya FEF

Ku bijyanye no gukumira, ni ngombwa kububaka ndetse na banyiri amazu kimwe no gusobanukirwa ibipimo bitandukanye bikoreshwa mugusuzuma imikorere yabyo. Muri ibi bipimo, K-agaciro, U-agaciro, na R-agaciro nibyo bikoreshwa cyane. Indangagaciro zose zigaragaza imikorere yubushyuhe bwibicuruzwa, harimo na FEF (ifuro rya polystirene). Iyi ngingo izasesengura isano iri hagati yizo ndangagaciro nuburyo zifitanye isano nibicuruzwa bya FEF.

K agaciro: coefficente yubushyuhe bwumuriro

K-agaciro, cyangwa ubushyuhe bwumuriro, ni igipimo cyubushobozi bwibikoresho byo gutwara ubushyuhe. Igice cyacyo ni Watts kuri metero-Kelvin (W / m · K). Hasi ya K-agaciro, nibyiza cyane, ariko ibi bivuze ko ibikoresho bitwara ubushyuhe neza. Kubikoresho bya FEF, K-agaciro ni ngombwa kuko bigira ingaruka ku bushobozi bwibikoresho byo kurwanya ubushyuhe. Mubisanzwe, ibicuruzwa byigenga bya FEF bifite K-agaciro gake, bigatuma bikora neza mubikorwa bitandukanye, kuva aho gutura kugeza ku nyubako zubucuruzi.

U-agaciro: Muri rusange coefficient de transfert

U-gaciro yerekana muri rusange coefficient de coiffure yibintu byubaka, nkurukuta, igisenge cyangwa hasi. Igaragarira muri Watts kuri metero kare-Kelvin (W / m² · K) kandi ntireba gusa ibikoresho byo kubika, ahubwo inita ku ngaruka ziterwa n’ikirere, ubushuhe n’ibindi bintu. Hasi U-gaciro, nibyiza gukingirwa, kuko bivuze ko ubushyuhe buke butakara cyangwa bwungutse binyuze mubintu byubaka. Mugihe cyo gusuzuma ibicuruzwa bya FEF, U-agaciro ningirakamaro kugirango wumve uko izakora mubikorwa nyabyo, cyane cyane iyo ihujwe nibindi bikoresho byubaka.

R agaciro: kurwanya ubushyuhe butemba

R-agaciro ipima ubushyuhe bwumuriro wibintu, byerekana uburyo irwanya ubushyuhe. Ibice byayo ni metero kare-Kelvin kuri watt (m² · K / W). Hejuru ya R-agaciro, nibyiza gukingirwa, bivuze ko uburyo bwiza bwo guhagarika ubushyuhe. Ibicuruzwa bya FEF mubisanzwe bifite R-indangagaciro zisumba izindi, bigatuma biba byiza mubwubatsi bukoresha ingufu. R-agaciro ni ngombwa cyane cyane kubafite amazu bashaka kugabanya ibiciro byingufu no kongera ubworoherane bwaho batuye.

Isano riri hagati ya K agaciro, U agaciro na R agaciro muri FEF

Gusobanukirwa isano iri hagati ya K-agaciro, U-agaciro na R-agaciro ningirakamaro mugusuzuma imikorere yibicuruzwa bya FEF. K-agaciro yibanda kubintu ubwabyo, R-agaciro gipima ukurwanya kwayo, na U-agaciro itanga ishusho yagutse yimikorere rusange yibintu byubaka.

Kugirango uhuze imibare, indangagaciro zikurikira zirashobora gukoreshwa:

- ** R-agaciro = 1 / K-agaciro **: Iri gereranya rivuga ko uko K-agaciro kagabanutse (byerekana ubushyuhe bwiza bwumuriro), R-agaciro kiyongera, bivuze kunoza imikorere yimikorere.

- ** U.

Kubicuruzwa bya FEF, K-agaciro gake bigira uruhare runini R-indangagaciro, nazo zifasha kugera kuri U-gaciro gake iyo zinjijwe mu nteko zubaka. Izi ngaruka zo guhuza imbaraga zituma FEF ikomeza guhitamo gukundwa kububatsi n'abubatsi bashaka ibishushanyo mbonera bikoresha ingufu.

Muncamake, K-agaciro, U-agaciro na R-agaciro ni ibipimo bifitanye isano bitanga ubushishozi bwimikorere yubushyuhe bwibicuruzwa bya FEF. Mugusobanukirwa iyi mibanire, abubatsi naba nyiri amazu barashobora gufata ibyemezo byuzuye kubijyanye nibikoresho byokwirinda, amaherezo bagashiraho ingufu nyinshi kandi nziza. Nkuko ingufu zikomeje kuba ikintu cyambere mubikorwa byubwubatsi, akamaro k’agaciro kaziyongera gusa, bityo rero bigomba gusuzumwa muguhitamo ibisubizo byokwirinda.
