Ihame
Imashini ya SUP-LDGR ya metero ya BTU (metero yubushyuhe) ikorana ubudasobanutse budasanzwe, ikoresha ihame ryambere ryo gupima ingufu zumuriro neza. Amazi ashyushye cyangwa akonje, atangwa nisoko yubushyuhe, yinjira muri sisitemu ihanitse yo guhanahana ubushyuhe, nka radiator, guhinduranya ubushyuhe, cyangwa umuyoboro uhuriweho - winjira mubushyuhe bwinshi cyangwa buke hanyuma ugasohoka mubushyuhe bwagabanutse cyangwa hejuru. Ubu buryo bworoshya kurekura ubushyuhe butagira akagero cyangwa kwinjiza kubakoresha binyuze mu guhanahana ingufu, guhuza ubushyuhe no gukonjesha hamwe nukuri neza. Mugihe amazi azenguruka muri sisitemu, sensor ya flux ikurikirana neza umuvuduko wikigereranyo, mugihe ibyuma bifata ubushyuhe byombi bikurikirana ubushyuhe bwamazi yagarutse mugihe. Indangagaciro zitunganywa na calculatrice ikora cyane, yerekana ubushyuhe bwuzuye bwasohotse cyangwa bwakiriwe neza.
Kubara ingufu bisobanurwa na formula:
Q = ∫ (τ0 → τ1) qm × Δh × dτ = ∫ (τ0 → τ1) ρ × qv × Δh × dτ
Aho:
- Q: Ubushyuhe bwuzuye bwarekuwe cyangwa bwakiriwe na sisitemu, bupimirwa muri joules (J) cyangwa kilowatt-amasaha (kWt).
- qm: Umuvuduko mwinshi wamazi ukoresheje metero yubushyuhe, mubiro kumasaha (kg / h).
- qv: Umuvuduko wamazi wamazi ukoresheje metero yubushyuhe, muri metero kibe kumasaha (m³ / h).
- ρ: Ubucucike bwamazi atembera muri metero yubushyuhe, mubiro kuri metero kibe (kg / m³).
- Δh: Itandukaniro ryinshi hagati yubushyuhe bwinjira nubuso bwa sisitemu yo guhanahana ubushyuhe, muri joules kuri kilo (J / kg).
- τ: Igihe, mu masaha (h).
Iyi metero igezweho ya BTU nigikoresho cyingirakamaro mugutezimbere imicungire yingufu zumuriro muri sisitemu yo guturamo, iy'ubucuruzi, ninganda HVAC hamwe nubushyuhe, itanga imikorere yizewe kandi ikora neza.
Icyitonderwa: ibicuruzwa birabujijwe gukoreshwa mugihe kitarimo guturika.
