Molo, Habr! Kwiiveki ezimbalwa ezidlulileyo yayiyimini eshushu, esasixubusha ngayo "kwigumbi lokutshaya" lengxoxo yomsebenzi. Emva kwemizuzu embalwa, incoko malunga nemozulu yajika yaba yingxoxo malunga neenkqubo zokupholisa kumaziko edatha. Kwi-techies, ngakumbi abasebenzi be-Selectel, oku akumangalisi; sihlala sithetha ngezihloko ezifanayo.
Ngexesha lengxoxo, sagqiba ekubeni sipapashe inqaku malunga neenkqubo zokupholisa kumaziko edatha ye-Selectel. Inqaku lanamhlanje limalunga nokupholisa kwamahhala, iteknoloji esetyenziswa kumaziko ethu edatha amabini. Ngezantsi kokusikwa kukho ibali elineenkcukacha malunga nezisombululo zethu kunye neempawu zazo. Iinkcukacha zobuchwephesha zabelwana yintloko yesebe lenkonzo ye-air conditioning kunye ne-ventilation systems, uLeonid Lupandin, kunye nomlobi ophezulu wezobugcisa uNikolay Rubanov.
Iinkqubo zokupholisa eSelectel
Nantsi inkcazelo emfutshane yokuba zeziphi iinkqubo zokupholisa esizisebenzisa kuzo zonke iindawo zethu. Siza kuqhubela phambili ekupholiseni simahla kwicandelo elilandelayo. Si eMoscow, eSt. Petersburg nakummandla waseLeningrad. Iimeko zemozulu kule mimandla zahlukile, ngoko sisebenzisa iindlela zokupholisa ezahlukeneyo. Ngendlela, kwiziko ledatha laseMoscow lalidla ngokuba ngumthombo wamahlaya ukuba abo bajongene nokupholisa babe ziingcali ezinamagama eKholodilin kunye neMoroz. Yenzeka ngengozi, kodwa nangoku...
Nalu uluhlu lwee-DCs ezinenkqubo yokupholisa esetyenziswayo:
- Berzarina - free-ukupholisa.
- Intyatyambo 1 - i-freon, ii-air conditioners zakudala zamaziko edatha.
- Intyatyambo 2 - chillers.
- Dubrovka 1 - chillers.
- Dubrovka 2 - i-freon, ii-air conditioners zakudala zamaziko edatha.
- Dubrovka 3 - free-ukupholisa.
Kumaziko ethu edatha, sizama ukugcina ubushushu bomoya kumda ophantsi wokucetyiswa uluhlu. Yi-23°C.
Malunga nokupholisa simahla
Kumaziko amabini edatha, Dubrovka 3 и Berzarina, sifake iinkqubo zokupholisa simahla, kunye nezinye ezahlukeneyo.
Inkqubo yokupholisa yasimahla kwi-DC Berzarina
Umgaqo osisiseko weenkqubo zokupholisa ngokukhululekileyo kukupheliswa kokutshintsha kobushushu, ukwenzela ukuba ukupholisa izixhobo zekhompyutha kwenzeke ngenxa yokuvuthuza ngomoya wesitrato. Icocwa ngokusebenzisa izihluzi, emva koko ingena kwigumbi lomatshini. Ekwindla nasebusika, umoya obandayo kufuneka “uhlanjululwe” ngomoya ofudumeleyo ukuze ubushushu bomoya ovuthuza phezu kwezixhobo bungatshintshi. Ehlotyeni eMoscow naseSt. Petersburg, kufuneka ukupholisa okongezelelekileyo.
Iiflephu zomoya ezihlengahlengiswayo
Kutheni ukupholisa kwamahhala? Ewe, kuba sisixhobo esisebenzayo setekhnoloji yokupholisa. Izixokelelwano zokupholisa zasimahla zikholisa ukuba zitshiphu ukusebenza kuneendlela zakudala zokupholisa umoya ezipholileyo. Enye inzuzo yokupholisa simahla kukuba iinkqubo zokupholisa azinayo impembelelo embi kangako kwindawo engqongileyo njengezipholileyo zomoya ezinefreon.
Iskimu sokupholisa sasimahla esine-aftercooling ngaphandle komgangatho ophakanyisiweyo
Inqaku elibalulekileyo: ukupholisa kwamahhala kusetyenziswa kumaziko ethu edatha kunye neenkqubo zokupholisa emva kokupholisa. Ebusika, akukho ngxaki ngokungena komoya obandayo wangaphandle - kupholile ngaphandle, ngamanye amaxesha nokuba kupholile kakhulu, ngoko ke iinkqubo ezongezelelweyo zokupholisa azidingeki. Kodwa ehlotyeni iqondo lobushushu lomoya liyenyuka. Ukuba sisebenzise ukupholisa okumsulwa kwasimahla, iqondo lobushushu ngaphakathi beliya kuba malunga ne-27 °C. Masikukhumbuze ukuba umgangatho wobushushu kaSelectel ngu-23°C.
Kwingingqi yaseLeningrad, ubushushu bemihla ngemihla bexesha elide, nangoJulayi, bumalunga nama-20°C. Kwaye yonke into iya kulunga, kodwa ngezinye iintsuku kushushu kakhulu. Kwi-2010, irekhodi lokushisa + 37.8 ° C lirekhodwe kummandla. Ukuqwalasela le meko, awukwazi ukubala ngokupheleleyo ukupholisa simahla - usuku olunye olushushu ngonyaka lungaphezu kokwaneleyo ukuba ubushushu buhambe ngaphaya komgangatho.
Ekubeni iSt. Petersburg kunye neMoscow ziyi-megacities ezinomoya ongcolileyo, sisebenzisa ukuhlanjululwa komoya kathathu xa siyithatha kwisitrato - izihlungi zeG4, G5 kunye neG7. Nganye ilandelayo ihluza uthuli olusuka kumaqhezu amancinci kunye namancinci, ukuze imveliso ibe ngumoya ococekileyo we-atmospheric.
Iifilitha zomoya
I-Dubrovka 3 kunye neBerzarina - ukupholisa kwamahhala, kodwa kuhluke
Ngenxa yezizathu ezininzi, sisebenzisa iindlela ezahlukeneyo zokupholisa simahla kula maziko edatha.
Dubrovka 3
I-DC yokuqala enokupholisa kwamahhala yayiyi-Dubrovka 3. Isebenzisa ukupholisa ngokuthe ngqo kwamahhala, incediswa yi-ABHM, umatshini wefriji wokufunxa osebenza kwigesi yendalo. Umatshini usetyenziswa njengokupholisa okongeziweyo kwimeko yobushushu behlobo.
Ukupholisa iziko ledatha usebenzisa iskimu sokupholisa samahhala kunye nomgangatho ophakamileyo
Esi sisombululo se-hybrid senze ukuba sikwazi ukufezekisa i-PUE ~ 1.25.
Kutheni i-ABM? Le yinkqubo esebenzayo esebenzisa amanzi endaweni ye-freon. I-ABM inempembelelo encinci kwindalo.
Umatshini we-ABM usebenzisa igesi yendalo, enikezelwa kuyo ngombhobho, njengomthombo wamandla. Ebusika, xa imoto ingafuneki, igesi inokutshiswa ukutshisa umoya opholileyo ngaphandle. Ixabiso eliphantsi kakhulu kunokusebenzisa umbane.
Umbono we-ABM
Ingcamango yokusebenzisa i-ABHM njengenkqubo yokupholisa emva kokupholisa ingomnye wabasebenzi bethu, injineli, owabona isisombululo esifanayo waza wacebisa ukuba ayisebenzise kwi-Selectel. Senze imodeli, sayivavanya, safumana iziphumo ezibalaseleyo kwaye sagqiba kwelokuba siyinyuse.
Umatshini wathatha malunga nonyaka kunye nesiqingatha ukwakha, kunye nenkqubo yokungenisa umoya kunye neziko ledatha ngokwayo. Yaqaliswa ukusebenza ngo-2013. Akukho ngxaki kuyo, kodwa ukusebenza kufuneka ufumane uqeqesho olongezelelweyo. Enye yeempawu ze-ABHM kukuba umatshini ugcina ukuhluka koxinzelelo ngaphakathi nangaphandle kwegumbi le-DC. Oku kuyimfuneko ukuqinisekisa ukuba umoya oshushu uyaphuma kwisixokelelwano sevalvu.
Ngenxa yomohluko woxinzelelo, akukho luthuli emoyeni, kuba lubhabha ngaphandle, nokuba luvela. Uxinzelelo olugqithisileyo lutyhala amasuntswana ngaphandle.
Iindleko zokugcinwa kwenkqubo zinokuba phezulu kancinci kunezokupholisa okuqhelekileyo. Kodwa i-ABHM ikuvumela ukuba ugcine ngokunciphisa ukusetyenziswa kombane ukufudumeza umoya kunye nokuwupholisa.
Berzarina
Umzobo wokuhamba komoya ngaphakathi kwegumbi leseva
Ukupholisa kwamahhala nge-adiabatic emva kokupholisa inkqubo isetyenziswe apha. Isetyenziswa ehlotyeni xa umoya ushushu kakhulu, namaqondo obushushu angaphezu kwama-23°C. Oku kwenzeka rhoqo eMoscow. Umgaqo wokusebenza we-adiabatic system kukupholisa umoya njengoko udlula kwiifilitha eziqulethe ulwelo. Yiba nomfanekiso we-rag emanzi apho amanzi aphuma khona, epholisa ilaphu kunye nomaleko osondeleyo womoya. Oku kuphantse ukuba indlela yokupholisa i-adiabatic isebenza njani kwiziko ledatha. Amathontsi amancinane amanzi atshizwa ecaleni kwendlela yokuhamba komoya, nto leyo enciphisa ubushushu bomoya.
Umgaqo wokusebenza wokupholisa i-adiabatic
Bagqiba ekubeni basebenzise ukupholisa kwamahhala apha kuba iziko ledatha libekwe kumgangatho ophezulu wesakhiwo. Oku kuthetha ukuba umoya ovuthayo ophuma ngaphandle ngokukhawuleza uyenyuka, kwaye awucinezeli ezinye iinkqubo, njengoko kunokwenzeka ukuba i-DC ibekwe kwimigangatho ephantsi. Ndiyabulela kule nto, isalathisi se-PUE yi ~ 1.20
Wathi akufumaneka lo mgangatho, savuya kuba safumana ithuba lokuyila nantoni na esiyifunayo. Umsebenzi ophambili yayikukudala i-DC enenkqubo yokupholisa esebenzayo nengabizi.
Inzuzo yokupholisa i-adiabatic kukulula kwenkqubo ngokwayo. Kulula kuneenkqubo ezine-air conditioners kwaye zilula ngakumbi kune-ABHM, kwaye ikuvumela ukuba ugcine amandla, iindleko zazo zincinci. Nangona kunjalo, kufuneka ilawulwe ngononophelo ukuqinisekisa ukuba ayipheli njengoko uFacebook wenza ngo-2012. Emva koko, ngenxa yeengxaki zokumisela iiparamitha zokusebenza, ilifu langempela lenziwe kwiziko ledatha kwaye laqala ukuna. .
Iiphaneli zokulawula
Le nkqubo isebenze iminyaka emibini kuphela, ngelo xesha siye sachonga inani leengxaki ezincinci esizilungisa kunye nabayili. Kodwa oku akukoyikisi, kuba kwixesha lethu kubalulekile ukuba sihlale sikhangela into entsha, ungalibali ukujonga izisombululo ezikhoyo.
Sihlala sikhangela amathuba okusebenzisa itekhnoloji entsha. Enye yazo sisixhobo esisebenza ngokuqhelekileyo kumaqondo obushushu angaphezu kwama-23°. Mhlawumbi siza kuthetha ngale nto kwelinye lamanqaku azayo, xa iprojekthi ifikelela kwinqanaba lokugqibela.
Ukuba ufuna ukwazi iinkcukacha malunga nezinye iinkqubo zokupholisa kwii-DCs zethu, ngoko nalo lonke ulwazi.
Buza imibuzo kumazwana, siya kuzama ukuphendula abaninzi kangangoko sinako.
