Ku bijyanye no gukingira insinga, ni ngombwa ko abubatsi n'abafite amazu basobanukirwa ibipimo bitandukanye bikoreshwa mu gusuzuma imikorere yabyo. Muri ibi bipimo, agaciro ka K, agaciro ka U, n'agaciro ka R nibyo bikunze gukoreshwa cyane. Ibi bipimo byose bigaragaza imikorere y'ubushyuhe bw'ibicuruzwa bikingira insinga, harimo na FEF (foam extruded polystyrene). Iyi nkuru izasuzuma isano iri hagati y'ibi bipimo n'uburyo bifitanye isano n'ibicuruzwa bikingira insinga bya FEF.
Agaciro ka K: igipimo cy'ubushyuhe
Agaciro ka K, cyangwa uburyo bwo gutwara ubushyuhe, ni igipimo cy'ubushobozi bw'igikoresho mu gutwara ubushyuhe. Igice cyacyo ni Watts kuri metero - Kelvin (W/m·K). Uko agaciro ka K kaba kari hasi, ni ko insulation iba nziza, ariko ibi bivuze ko ibikoresho bidatwara ubushyuhe neza. Ku bikoresho bikingira FEF, agaciro ka K ni ingenzi kuko bigira ingaruka ku bushobozi bw'igikoresho mu guhangana n'ubushyuhe. Ubusanzwe, ibikoresho bikingira FEF bifite agaciro ka K kari hasi, bigatuma bikora neza mu bikorwa bitandukanye, kuva ku mazu yo guturamo kugeza ku mazu y'ubucuruzi.
Agaciro ka U: Igipimo rusange cyo kohereza ubushyuhe
Agaciro ka U kerekana igipimo rusange cy’ubushyuhe bw’ikintu cy’inyubako, nk’urukuta, igisenge cyangwa hasi. Kigaragazwa muri Watts kuri metero kare - Kelvin (W/m²·K) kandi ntikibanda gusa ku bikoresho byo gukingira, ahubwo kinareba ingaruka z’imyobo y’umwuka, ubushuhe n’ibindi bintu. Uko agaciro ka U kaba kari hasi, ni ko gukingira birushaho kuba byiza, kuko bivuze ko ubushyuhe buke butakaza cyangwa buboneka binyuze mu kintu cy’inyubako. Mu gusuzuma ibikoresho byo gukingira bya FEF, agaciro ka U ni ingenzi kugira ngo usobanukirwe uko kazakora mu bikorwa nyabyo, cyane cyane iyo gahujwe n’ibindi bikoresho by’ubwubatsi.
Agaciro ka R: kurwanya ubushyuhe butemba
Agaciro ka R gapima ubushyuhe bw'ikintu, kakerekana uburyo kirwanya ubushyuhe. Ibice byacyo ni metero kare - Kelvin kuri watt (m²·K/W). Uko agaciro ka R kaba kari hejuru, niko ubushyuhe burushaho kuba bwiza, bivuze ko ibikoresho bigabanya ubushyuhe. Ibikoresho bya FEF bikunze kugira agaciro ka R gakomeye, bigatuma biba byiza mu bwubatsi bukoresha ingufu nke. Agaciro ka R ni ingenzi cyane ku ba nyir'amazu bashaka kugabanya ikiguzi cy'ingufu no kongera ihumure ry'aho batuye.
Isano iri hagati y'agaciro ka K, agaciro ka U n'agaciro ka R mu gukingira FEF
Gusobanukirwa isano iri hagati y’agaciro ka K, agaciro ka U n’agaciro ka R ni ingenzi cyane mu gusuzuma imikorere y’ibikoresho bya FEF byo gukingira. Agaciro ka K kibanda ku bikoresho ubwabyo, agaciro ka R gapima ubukana bwabyo, naho agaciro ka U gatanga ishusho yagutse y’imikorere rusange y’ikintu cy’inyubako.
Kugira ngo iyi mibare ihuzwe, hashobora gukoreshwa formula ikurikira:
- **Agaciro ka R = 1 / Agaciro ka K**: Iki kigereranyo kivuga ko uko agaciro ka K kagabanuka (bigaragaza ko ubushyuhe bugenda neza), agaciro ka R karazamuka, bivuze ko ubushobozi bwo gukingira burushaho kwiyongera.
- **Agaciro ka U = 1 / (Agaciro ka R + izindi resistor)**: Iyi formula igaragaza ko agaciro ka U kadaterwa gusa n'agaciro ka R k'urwego rw'ubushyuhe, ahubwo kanaterwa n'ibindi bintu nk'icyuho cy'umwuka n'ibiraro by'ubushyuhe.
Ku bikoresho byo gukingira inyubako bya FEF, agaciro ka K gake gatuma agaciro ka R kaba gake, ibyo bigatuma agaciro ka U gake gake gashyirwa mu nyubako. Iyi ngaruka y’ubufatanye ituma gukingira inyubako bya FEF biba amahitamo akunzwe n’abubatsi n’abubatsi bashaka ibishushanyo mbonera bikoresha ingufu nke.
Muri make, agaciro ka K, agaciro ka U n'agaciro ka R ni ibipimo bifitanye isano bitanga ubumenyi bw'ingenzi ku mikorere y'ubushyuhe bw'ibicuruzwa bya FEF bikingira ubushyuhe. Mu gusobanukirwa iyi mibanire, abubatsi n'abafite amazu bashobora gufata ibyemezo bisobanutse ku bikoresho bikingira ubushyuhe, amaherezo bagahanga ahantu ho gutura hakoresha ingufu nke kandi heza. Uko ingufu zikomeza kuba ingenzi mu nganda z'ubwubatsi, akamaro k'izi ndangagaciro kazakomeza kwiyongera, bityo bigomba kwitabwaho mu guhitamo ibisubizo bikingira ubushyuhe.
