Gusobanukirwa Gukwirakwiza R-Indangagaciro: Igice hamwe nuyobora
Iyo bigeze kumikorere ya insulation, kimwe mubipimo byingenzi tugomba gusuzuma ni R-agaciro. Agaciro gapima ubukana bwokwirinda ubushyuhe; hejuru R-indangagaciro yerekana imikorere myiza yo gukumira. Nyamara, R-indangagaciro zishobora kugaragarira mubice bitandukanye, cyane cyane muri Reta zunzubumwe za Amerika (USC) hamwe na Imperial Sisitemu (Sisitemu Imperial). Iyi ngingo izasesengura R-agaciro gakoreshwa mugukingirana nuburyo bwo guhindura sisitemu zombi.
R-agaciro ni iki?
R-agaciro ni igipimo cyo kurwanya ubushyuhe bukoreshwa munganda zubaka. Igereranya ubushobozi bwibikoresho byo kurwanya ihererekanyabubasha. R-agaciro ningirakamaro muguhitamo neza insulation mugukomeza gushyuha mugihe cy'itumba no gukonja mugihe cyizuba. Hejuru ya R-agaciro, nibyiza gukingirwa.
R-agaciro ibarwa hashingiwe ku bunini bwibikoresho, ubushyuhe bwumuriro, hamwe nubuso ubushyuhe bwimurirwamo. Inzira yo kubara R-agaciro niyi ikurikira:
\ [R = \ frac {d} {k} \]
Aho:
- \ (R \) = R agaciro
- \ (d \) = uburebure bwibintu (muri metero cyangwa santimetero)
- K = ubushyuhe bwumuriro wibikoresho (muri Watts kuri metero-Kelvin cyangwa amashanyarazi yu Bwongereza ku isaha-metero-Fahrenheit)
Ibice R-agaciro
Muri Amerika, R-indangagaciro zikunze kugaragara muri sisitemu ya Imperial, ukoresheje ibice nka BTU (British Thermal Units) hamwe na metero kare. Ibice bisanzwe kuri R-indangagaciro muri Amerika ni:
** R-agaciro (Imperial) **: BTU · h / ft² · ° F.
Ibinyuranye, sisitemu ya metero ikoresha ibice bitandukanye, bishobora kuba urujijo mugereranya ibikoresho byo kubika uturere dutandukanye. Ibipimo bya R-agaciro ni:
- ** R-agaciro (metric) **: m² · K / W.
Guhindura ibice
Kugereranya neza ibikoresho byo kubika ahantu cyangwa sisitemu zitandukanye, ni ngombwa kumva uburyo bwo guhindura R-indangagaciro hagati ya sisitemu ya Imperial na Metric. Guhindura hagati yibi bice byombi bishingiye ku isano iri hagati ya BTU (British Thermal Units) hamwe na watts, hamwe nubuso nubushuhe butandukanye.
1. ** Kuva Imperial kugeza Metric **:
Guhindura R agaciro kuva Imperial kugera kuri Metric, urashobora gukoresha formula ikurikira:
R_ {metric} = R_ {ingoma times \ inshuro 0.1761 \
Ibi bivuze ko kuri buri R-agaciro kagaragajwe mucyongereza, kugwiza 0.1761 kugirango ubone R-agaciro kangana muri metric.
2. ** Kuva kuri Metric kugeza Imperial **:
Ibinyuranye, kugirango uhindure R agaciro kuva metric ukajya mubwami, formula ni:
\ [R_ {Imperial} = R_ {Ibipimo} \ inshuro 5.678 \]
Ibi bivuze ko kuri buri R-agaciro kagaragajwe muri metric, kugwiza 5.678 kugirango ubone R-agaciro kangana mubwami.
Ubusobanuro bufatika
Gusobanukirwa ihinduka hagati yingoma nuburinganire bwa R-agaciro ningirakamaro kububatsi, abubatsi, na banyiri amazu. Mugihe uhitamo insulasiyo, uzahura na R-indangagaciro zigaragara mubice bitandukanye, cyane cyane kumasoko yisi yose aho ibicuruzwa biva mubihugu byinshi bitandukanye.
Kurugero, niba nyirurugo muri Reta zunzubumwe zamerika atekereza kugura insulasiyo ifite R-agaciro ka 3.0 m² · K / W, bakeneye guhindura ibi mubice byubwami kugirango babigereranye nibicuruzwa byaho. Ukoresheje uburyo bwo guhindura, R-agaciro mubice byubwami ni:
\ [R_ {ingoma} = 3.0 \ inshuro 5.678 = 17.034 \]
Ibi bivuze ko insulasiyo ifite R-agaciro kangana na 17.0 BTU · h / ft² · ° F, ishobora kugereranwa nibindi bikoresho byo kwisoko ku isoko.
R-agaciro rero nikimenyetso cyingenzi cyo gusuzuma imikorere yubushyuhe bwibikoresho. Gusobanukirwa R-agaciro hamwe no guhinduranya hagati yimigenzo gakondo yo muri Amerika hamwe nubwami ningirakamaro mugufata ibyemezo byokwirinda neza. Waba uri umwubatsi, umwubatsi, cyangwa nyir'urugo, ubu bumenyi buzagufasha guhitamo uburyo bwiza bwo gukenera ibyo ukeneye, kwemeza ko aho utuye hakoreshwa ingufu kandi neza. Mugihe inganda zubwubatsi zikomeje gutera imbere, gusobanukirwa ibi bipimo ningirakamaro mubikorwa byubaka no kubungabunga ingufu.
Niba ufite ikibazo, nyamuneka wumve neza ikipe ya Kingflex.
