Ngokungafaniyo nezinye iimveliso, umlandeli uhlala ephila ubomi benkonzo iminyaka eliqela okanye ngaphezulu kweshumi leminyaka, kwaye ixabiso layo liyahluka. Ngoko ke, xa sikhetha umqhubi, kufuneka sikhethe enye efanelekileyo kwaye inomlinganiselo ophezulu weendleko zokusebenza. Namhlanje, makhe sifunde malunga neengongoma eziphambili zokukhetha umlandeli. Okokuqala, ngokusekelwe kwiiparitha ezimbini ezisisiseko zomqhubi ofunekayo - umthamo womoya kunye noxinzelelo lomoya, misela imodeli kunye nenani lomqhubi, kunye namandla afunekayo ngetafile yokusebenza (zonke iincwadana zeemveliso zefeni zinedatha efanelekileyo). Kweli nqanaba, kunokubakho ngaphezu kwemveliso enye ehlangabezana neemfuno; emva koko sidibanisa injongo yomqhubi, iimfuno zenkqubo, kunye neemeko zokusebenza (imeko yokusetyenziswa) ukukhetha uhlobo, imodeli, isakhiwo, kunye nezinto eziphathekayo zefeni ukuhlangabezana neemeko zokusebenza ezifunekayo. Sizama ukwenza ukuhamba okulinganiselweyo kunye noxinzelelo olulinganisiweyo lomqhubi ngokusondeleyo kunokwenzeka ukuhamba kunye noxinzelelo olufunwa yinkqubo, ukwenzela ukuba indawo yokusebenza yomqhubi isondele kwindawo esebenzayo yeempawu zefeni. Imigaqo ethile yile ilandelayo:
Ngaphambi kokukhetha ifeni, umntu kufuneka aziqhelanise nemveliso kunye nomgangatho wezixhobo zokungenisa umoya eTshayina, kubandakanya neentlobo, iinkcukacha zabalandeli abaveliswayo, kunye nokusetyenziswa okuthe ngqo kweemveliso ezahlukeneyo. Bamele baqonde imeko yangoku yemarike yabalandeli baseTshayina.
② Kuxhomekeka kwiimpawu ezibonakalayo kunye neekhemikhali zerhasi ehanjiswa yi-ventilator, khetha i-ventilator efanele injongo ethile. Umzekelo, ukuba kuthuthwa iigesi ezinokugqabhuka okanye ezinokutsha, kufuneka kukhethwe isixhobo sokungenisa umoya esithintela uthuli, kwaye umgangatho ofunekayo wokumelana nokudubula kwefeni kufuneka umiselwe; ukuba yeyokususwa kothuli okanye ukuhambisa umgubo wamalahle, ukususwa kothuli okanye umgubo wamalahle wokungenisa umoya kufuneka kukhethwe; ukuba yeyokuhambisa iigesi ezityiwayo, kufuneka kukhethwe i-ventilator ekwaziyo uku- rhorho, kunye nezinto zokumelana nokutyiwa (ezifana ne-fiberglass eyomeleziweyo yeplastiki okanye i-PP) kufuneka imiselwe; ukuba isebenza kwindawo yobushushu obuphezulu okanye ukuhambisa iigesi eziphezulu zobushushu, kufuneka kukhethwe i-ventilator ephezulu, kunye nobushushu bendalo kunye nobushushu begesi ehanjiswayo kufuneka iqondwe.
③ Ukuba kukho ngaphezu kweentlobo ezimbini zezixhobo zokungenisa umoya ezifumanekayo kwitshati yokusebenza, leyo inobuchule obuphezulu, ubungakanani obuncinci kunye noluhlu olubanzi lohlengahlengiso kufuneka lubekwe phambili. Ngokuqinisekileyo, unokuthelekisa ngokubhekiselele kwindleko-esebenzayo kwaye wenze isigqibo ngokulinganisa i-pros and cons.
④ Ukuba i-diameter ye-fan i-impeller ekhethiweyo inkulu kakhulu kuneyokuqala i-fan impeller, ukuze usebenzise i-motor shaft yasekuqaleni, iibheringi kunye nezixhaso, kuyafuneka ukubala ixesha lokuqalisa imoto, amandla eenxalenye zabalandeli bokuqala, kunye nesantya esibalulekileyo sokujikeleza kweshafti.
⑤ Xa ukhetha ifeni ye-centrifugal, ukuba umbane wenjini oxhotyiswe ngawo ungaphantsi okanye ulingana nama-75KW, ivalve ngeenjongo zokuqalisa kuphela ayinakufakwa. Xa ukhetha ibhoyili ye-centrifugal yokukhupha i-fan yokukhupha igesi eshushu ye-flue okanye umoya, ivalve yokuqalisa kufuneka ibonelelwe ukukhusela ukulayisha ngaphezulu ngexesha lokusebenza okubandayo.
⑥ Kwiinkqubo zokungenisa umoya ezineemfuno zengxolo, ukhetho kufuneka luqale ngee-ventilators ezinobunkunkqele obuphezulu kunye nesantya esisezantsi sokujikeleza se-impeller, kwaye zisebenze kwindawo yazo ephezulu yokusebenza. Ukunciphisa ingxolo okuhambelanayo kunye namanyathelo okunciphisa i-vibration kufuneka kwakhona athathwe ngokusekelwe kwindlela ingxolo kunye nokungcangcazela okubangelwa yinkqubo yokungenisa umoya. Amanyathelo okunciphisa i-vibration kwii-ventilators kunye neemotor ngokubanzi zinokufezekiswa ngeziseko zokunciphisa ukungcangcazela, kunye nezixhobo ezahlukeneyo zokunciphisa ukungcangcazela kunokukhethwa ngokuxhomekeke kwindlela yofakelo lwee-ventilators.
⑦ Xa ukhetha i-ventilator, kuyacetyiswa ukuba ugweme ukusebenzisa i-ventilator ngokuhambelana okanye uchungechunge lokusebenza. Ukuba umsebenzi onjalo awunakuphepheka, kucetyiswa ukuba ukhethe ii-ventilators zemodeli efanayo kunye nokusebenza okufanayo ukuze usebenze ngokudibeneyo. Xa usebenzisa uxhulumaniso lwechungechunge, kufuneka kubekho uxhulumaniso oluthile lwepayipi phakathi kwesigaba sokuqala kunye nesesibini se-ventilators.
