Hien yabonye izina rikomeye bitewe n'umushinga wa 60203 ㎡ wa sitasiyo ya Qinghai Expressway. Kubera iyo mpamvu, sitasiyo nyinshi za Qinghai Communications and Construction Group zahisemo Hien uko bikwiye.
Qinghai, imwe mu ntara zikomeye ziri ku kibaya cya Qinghai-Tibet, ni ikimenyetso cy'ubukonje bukabije, imisozi miremire n'umuvuduko muke. Hien yakoreye neza sitasiyo 22 za lisansi za Sinopec mu Ntara ya Qinghai mu 2018, kandi kuva mu 2019 kugeza 2020, Hien yakoreye sitasiyo zisaga 40 za lisansi muri Qinghai imwe nyuma y'indi, zikora neza kandi neza, ibi bikaba bizwi cyane mu nganda.
Mu 2021, ibikoresho byo gushyushya imashini zishyushya ikoresha umwuka wa Hien byatoranijwe mu mushinga wo kuvugurura ubushyuhe bw'ishami rya Haidong n'ishami rya Huangyuan ry'ikigo gishinzwe gucunga no gukora imihanda ya Qinghai. Ubuso bwose bw'ubushyuhe ni metero kare 60.203. Mu mpera z'igihembwe cy'ubushyuhe, ibikoresho by'umushinga byari bihamye kandi bikora neza. Muri uyu mwaka, Ubuyobozi bw'Umuhanda wa Haidong, Ubuyobozi bw'Umuhanda wa Huangyuan n'Akarere ka Huangyuan, na ko kari mu itsinda ry'itumanaho n'ubwubatsi rya Qinghai, byahisemo ibikoresho byo gushyushya imashini zishyushya imashini zikoresha umwuka wa Hien nyuma yo kumenya ingaruka z'imikorere y'imashini zishyushya ikoresha umwuka wa Hien kuri sitasiyo ya Qinghai Expressway.
Noneho, reka twige byinshi ku mushinga wa sitasiyo yihuta ya Hien mu kigo gishinzwe gucunga no gukora imihanda ya Qinghai.
Incamake y'umushinga
Birumvikana ko izi sitasiyo zikoresha umuvuduko mwinshi zabanje gushyushywa na boilers za LNG. Nyuma y'iperereza ryakorewe aho hantu, inzobere za Hien muri Qinghai zasanze hari ibibazo n'amakosa mu buryo bwo gushyushya izi sitasiyo zikoresha umuvuduko mwinshi. Icya mbere, imiyoboro y'amashanyarazi y'umwimerere yose yari DN15, itashoboraga guhaza icyifuzo cy'ubushyuhe na gato; icya kabiri, umuyoboro w'amashanyarazi y'umwimerere w'aho hantu warangiritse kandi warangiritse cyane, ntiwashoboraga gukoreshwa mu buryo busanzwe; icya gatatu, ubushobozi bwa transformateur y'aho hantu ntibuhagije. Hashingiwe kuri ibi bihe no ku bidukikije nk'ubukonje bukabije n'uburebure bwinshi, itsinda rya Hien ryahinduye umuyoboro waryo w'amashanyarazi w'umwimerere muri DN20; ryasimbuye umuyoboro wose w'amashanyarazi y'umwimerere; ryongereye ubushobozi bwa transformateur aho hantu; kandi ryashyize ibikoresho byo gushyushya byatanzwe aho hantu ibigega by'amazi, ipompo, ikwirakwizwa ry'amashanyarazi n'izindi sisitemu.
Igishushanyo mbonera cy'umushinga
Iyi sisitemu ikoresha uburyo bwo gushyushya bwa "circulating heating system", ari byo "moteri nkuru + terminal". Inyungu yayo iri mu kugenzura no kugenzura uburyo bwo gukora, aho sisitemu yo gushyushya ikoreshwa mu gihe cy'itumba ifite ibyiza nko kudahungabana neza mu bushyuhe no kubika ubushyuhe; Gukoresha byoroshye, gukoresha neza, kandi byizewe; Ihendutse kandi ikora neza, ikiguzi gito cyo kuyibungabunga, igihe kirekire cyo kuyikoresha, nibindi. Amazi yo hanze n'amazi yo mu ipompe z'ubushyuhe bifite sisitemu zo kwirinda gukonjesha, naho ibikoresho bya pompe z'ubushyuhe bifite igikoresho cyizewe cyo kubigenzura. Buri gikoresho kigomba gushyirwaho udupira tudahungabana twakozwe mu bikoresho bya kabutike kugira ngo tugabanye urusaku. Ibi bishobora kandi kugabanya ikiguzi cyo kuyikoresha.
Kubara umutwaro w'ubushyuhe: hakurikijwe ubukonje bukabije n'imiterere y'ikirere cyo hejuru, ndetse n'imiterere y'ikirere cyo mu gace, umutwaro w'ubushyuhe mu gihe cy'itumba ubarwa nka 80W/㎡.
Kugeza ubu, ibikoresho byo gushyushya bya Hien air source byatangiye gukora neza nta kibazo na kimwe cyabayeho kuva byashyirwaho.
Ingaruka ku ikoreshwa
Imashini zishyushya ipompe y'umwuka ya Hien muri uyu mushinga zikoreshwa mu gice gifite uburebure bwa metero kare 3660 kuri sitasiyo ya Qinghai Expressway. Ubushyuhe busanzwe mu gihe cyo gushyushya ni - 18 °, naho ubushyuhe bukonje cyane ni - 28 °. Igihe cy'umwaka umwe cyo gushyushya ni amezi 8. Ubushyuhe bw'icyumba ni hafi 21 °, naho ikiguzi cy'igihe cyo gushyushya ni 2.8 yuan / m2 ku kwezi, bingana na 80% byo kuzigama ingufu ugereranyije na boiler ya LNG ya mbere. Bigaragara ku mibare yabanje kubarwa ko umukoresha ashobora kwishyuza ikiguzi nyuma y'ibihe bitatu gusa byo gushyushya.
