I. Kugereranya Ubushobozi bwo Guhindura Ubushuhe: Ivyuma Bihindura Ubushuhe Bitanga Ivyiza Bihambaye
1. Igikoresho co guhindura ubushuhe: Ubushobozi bwo guhindura ubushuhe burengeye cane
Igikoresho co guhindura ubushuhe bw’amasahani gikoresha ubuhinga bw’amasahani y’amabuye, kigatuma amazi ari mu mirongo mikeyi ashobora gutuma haba umuvurungano w’uburemere bwinshi-mbere no ku mibare mike ya Reynolds, gutyo kigakuraho burundu ibibazo bijanye n’uguca mu mazi no guhagarara. )-incuro zitatu canke zitanu z’ibikoresho bisanzwe vy’uguhindura ubushuhe vy’ibikoko-n’ivyo mu bikoresho -vy’amazi. Ikindi kandi, ibinyamakuru bikanye n’ibishushe bigenda mu buryo buteye ubwoba -ubu mu gihe cose, bikaba bituma hakoreshwa cane cane ubudasa bw’ubushuhe; itandukaniro ry’ubushuhe bw’iherezo rishobora kuba rito cane nk’iry’ibara ry’umuhondo 1 , bikaba bituma haba uguhinduranya ubushuhe gutomoye cane. Mu bihe vy’ibikorwa bingana, ivyo bisobanura kugabanya ugukoresha inguvu n’ugutakaza ubushuhe buke.
2. Igikoresho co guhindura ubushuhe c’igikoko-na-Igikoresho co guhindura ubushuhe: Ubushobozi bwo guhindura ubushuhe buraringaniye canke buri hasi.
Mu bikoresho bihindura ubushuhe vy’igikoko-na-vy’amazi, amazi atemba atandukanye aciye ku ruhande rw’amazi n’uruhande rw’igikoko; ku bw’ivyo, ukuvanga kw’imivurungano kuragoyagoya, bikaba bituma habaho uturere tw’amazi yapfuye be n’imihora y’uguca mu nzira. Ivyo bituma ubushuhe buva ku 300 gushika ku 1000 W/(m2·℃) gusa. Ikoreshwa ryiza ry'itandukaniro ry'ubushuhe hagati y'ibimenyeshamakuru bishushe n'ibikonje ni rito, n'itandukaniro ry'ubushuhe busanzwe rirenga degre 5 . Kugira ngo umuntu ashobore gushitsa ibisabwa vyo gutanga ubushuhe bingana, birakenewe ko haba ahantu hanini ho gutanga ubushuhe, ivyo bikaba bituma hakoreshwa inguvu nyinshi muri rusangi ugereranyije n’ibikoresho bihindura ubushuhe vy’amasahani.
II. Igereranyo ry’imiterere n’ibirenge: Ivyuma bihindura ubushuhe ku masahani birakomeye cane kandi biraremereye cane
1. Igikoresho co guhindura ubushuhe bw’isahani: Ingano nini, iremereye, kandi nta kirenge gifise.
Ivyuma bihindura ubushuhe vy’amasahani bifise ubuhinga bukomeye cane, bifise uburebure bw’ubushuhe ku buringanire buva kuri 200 gushika kuri 1000 m2/m3-burengeye kure ubw’ibikoresho vy’ibikoko -n’ibikoresho vy’amazi. Kubera ko amasahani afise uburebure bwa 0,4 gushika kuri 0,8 mm gusa, uburemere bwayo bwose ni nk’ica gatanu c’igikoresho co guhindura ubushuhe c’igikoko-n’igikoresho co guhindura ubushuhe c’imiyoboro y’ibipimo bingana. Kubera ko ata kibanza kinini bisaba co gushiramwo, birabereye cane amahinguriro, inyubakwa, n’imigambi y’inganda mitomito-aho ikibanza ari gito; ikindi kandi, zituma umuntu atanga amahera make yo kubitwara no kubishiramwo, ivyo bikaba bitanga inyungu zidasanzwe ku bijanye no gutwara ibintu mu mahanga.
2. Igikoresho co guhindura ubushuhe c’igikoko-na-Igikoresho co guhindura ubushuhe: Ni kinini, gikomeye, kandi gifata ikibanza kinini.
Ivyuma bihindura ubushuhe vy’igikoko-na-vy’imiyoboro birimwo ibihimba bikomeye-bikora cane-nk’igikoko, umugwi w’imiyoboro, urupapuro rw’imiyoboro, n’ibipfukisho -bituma haba igihimba kinini kandi kinini cane gifise uburebure bw’ubushuhe bwo guhindura ubushuhe bwa m33/55 gusa. Mu bipimo bisa n’ivyo guhindura ubushuhe, ubunini bwavyo n’ibirenge vyavyo biraruta incuro nyinshi ivy’ibikoresho bihindura ubushuhe vy’ubwoko bw’amasahani-; ikindi kandi, bisaba ko hashirwaho imishinge minini kandi idahinduka, ivyo bikaba bituma umuntu atanga amahera menshi yo kubitwara, kubiduza no kubishiraho. Ku bw’ivyo, ntizibereye ku bikorwa vy’imigambi bifise ikibanza gito canke gikomeye.
III. Igereranyo ry'Imibereho y'Ibikorwa: Ivyuma bihindura Ubushuhe vy'Igikoko-na-Birabereye Imibereho y'Ibikorwa Bikomeye
1. Igikoresho co guhindura ubushuhe bw’isahani: Kibereye ku rugero, uburyo bwo gukora busanzwe.
Kubera ingorane ziterwa n’ibipfukisho vyavyo n’imiterere y’amasahani, ibikoresho bihindura ubushuhe bw’amasahani birafise ubushobozi buke bwo guhangana n’ubushuhe n’imikazo myinshi. Ivyo bikoresho vyabo bikoreshwa bishingiye ku bushuhe buri munsi canke bungana na degre 180 n’inguvu ziri munsi canke zingana na 2,5 MPa. Ku bw’ivyo, zibereye gusa amazi asukuye-nk’amazi meza, amavuta, n’ibikoresho vy’imiti bitagira uburozi-kandi zibereye cane mu bikorwa vy’ubuhinga busanzwe biboneka mu bikoresho vy’ubuhinga bwa HVAC, ibikorwa vyo gushusha amazi, inganda zisanzwe n’inganda rusangi, gutunganya ibifungurwa. Ntizibereye ahantu hari ubushuhe bwinshi cane, umukazo mwinshi canke ibintu bishobora gusenyura cane. Vyongeye, imigende yabo y’amazi mikeyi irakunda gufunga; rero, gukoresha ibinyamakuru birimwo ibintu vyinshi canke ibintu vyinshi bihumanye birabujijwe cane.
2. Shell-na-Tube Heat Exchanger: Ibereye ku bihe bikomeye vy’ibikorwa birimwo ubushuhe bwinshi n’imikazo myinshi.
Igikoresho co guhindura ubushuhe c’igikoko-n’-tube gifise ubuhinga bukomeye kandi bushikamye bwose -ivyuma, vyirata ubushobozi budasanzwe bwo guhangana n’umuvuduko munini n’ubushuhe bwinshi; irashoboye kwihanganira ibihe vy’ibikorwa birenze degre 400 na 10 MPa. Ku bw’ivyo, ihagaze nk’ihitamwo ryiza ry’inganda zikomeye nk’ivy’amavuta ya peteroli, ivy’ubuhinga bw’imiti, ivy’amashanyarazi, ivy’ivyuma, n’ivy’imishwarara. Ico gikoresho kirangwa n’imihora myinshi y’amazi atemba be n’ukwihanganira cane ibimenyeshamakuru bitandukanye, bikaba bituma gishobora gukorana n’amazi arimwo ibisigazwa, ibihimba, uburemere bwinshi canke ubuhumane buhambaye. Ubushobozi bwayo bwo guhangana n’uguhumana n’ugufunga buraruta kure n’iyo ubw’ibikoresho bihindura ubushuhe bw’amasahani, ivyo bikaba vyerekana ko bishobora guhinduka bidasanzwe mu bihe bitandukanye bikoreshwa.
Niba ushaka kumenya vyinshi ku bikoresho bihindura ubushuhe canke ushaka kubigura, wohereze ubutumwa kuri9988shiyaoshuai@gmail.com, tuzokwishura mu gihe tumaze kubona ubutumwa!
