Igipimo cya BTU ni iki?

Igipimo cya BTU ni igikoresho gikoreshwa mu gupima ikoreshwa ry'ubushyuhe (ingufu), cyane cyane mu kugenzura ubushyuhe buva mu mazi (nk'amazi, ethylene glycol, nibindi) mu gihe cy'amazi atemba. Gikunze gukoreshwa mu bihe nka HVAC (Ubushyuhe, Ubuhumekero, n'Ubukonje), imicungire y'ingufu mu nganda, na sisitemu zo gukonjesha.

Imikorere y'ingenzi:

Mu gupima umuvuduko w'amazi n'itandukaniro ry'ubushyuhe hagati y'aho yinjira n'aho asohokera, ibarura agaciro k'ubushyuhe ikoresheje formula za thermodynamic. Iyi yunithi ubusanzwe ni British Thermal Unit (BTU) cyangwa ibikomoka kuri yo (nka MBTU, miliyoni za BTU).
Ifishi yo kubara ni iyi:
Q=Igipimo cy'amazi×Ubushobozi bwihariye bw'ubushyuhe bw'amazi×(Ubushyuhe bw'aho yinjira−Ubushyuhe bwo gusohoka)
(aho ubushyuhe, Q iri muri BTU).

Ishyirwa mu byiciro n'amahame ngenderwaho:

Dukurikije Ihame ryo Gupima:
Ubwoko bwa Mekanike: Itera amazi gutembera mu bice bya mekanike nka impellers kandi ikabara ubushyuhe ikoresheje ibyuma bipima ubushyuhe (bisa n'ibipimo by'amazi bisanzwe).
Ubwoko bwa Ultrasonic: Ibipimo by'amazi bikoreshwa hakoreshejwe uburyo bwa Ultrasonic bwo gukora igihe cyo kuguruka, bitanga ubuziranenge bwo hejuru kandi nta kwangirika kwa mekanike (urugero, Inline ultrasonic heat meters).
Ubwoko bwa Electromagnetic: Ipima urujya n'uruza rw'amazi hashingiwe ku ikoreshwa rya electromagnetic, rikwiriye gukoreshwa mu guteka amazi.

Uburyo bwo gushyiraho:
Ubwoko bwo gushyiramo (Imbere): Ishyizwe mu miyoboro mu buryo butaziguye, ikwiriye imiterere y'inganda zisanzwe.
Ubwoko bwa Clamp-On: Ifatanye n'uruhande rw'inyuma rw'imiyoboro idakubiswe, yoroshye kuyishyiraho ariko ifite imiterere y'imiyoboro.

Ingero z'Ikoreshwa:
Gucunga Ingufu mu Nyubako: Gukurikirana ikoreshwa ry'ubushyuhe mu buryo bwo gukonjesha umwuka, ibyuma bitanga ubushyuhe, cyangwa sisitemu z'ubushyuhe kugira ngo habeho isesengura ry'uburyo bwo kwishyura cyangwa gukoresha neza ingufu.
Uburyo bwo gukora mu nganda: Gupima ubushyuhe mu buryo bwo gukonjesha/gushyushya mu nganda nka tekiniki y'ibinyabutabire no gutunganya ibiribwa.
Uburyo bwo Gukonjesha: Gukurikirana uburyo ingufu zikoreshwa mu kubika ibintu bikonjesha n'ibikonjesha.

Ibyiza:
Ingano y'Ingufu Ikoreshwa: Ifasha abakoresha gusobanukirwa neza ikoreshwa ry'ubushyuhe no kunoza uburyo ingufu zikoreshwa.
Ubuhanga bwo hejuru: Ubwoko bwa Ultrasonic bushobora gukora amakosa ari hasi cyane nka ± 0.5%, bugahura n'ibisabwa mu kwishyurana.
Ubwenge: Ishyigikira kohereza amakuru ari kure, kubika inyandiko z'amateka, no guhuza na sisitemu zo gucunga ingufu (EMS).
