1. Ukumiselwa kobubanzi bombhobho wokungenisa umoya womgodi wezoqoqosho
1.1 Iindleko zokuthenga umbhobho wokungenisa umoya kwimigodi
Njengoko ububanzi bombhobho wokungenisa umoya wemigodi bunyuka, izinto ezifunekayo nazo zinyuka, ngoko ke ixabiso lokuthenga lombhobho wemigodi yemigodi nalo liyenyuka.Ngokohlalutyo lweenkcukacha-manani lwexabiso elinikwe ngumenzi webhobho lokungenisa umoya emigodini, ixabiso lombhobho wokungenisa umoya wasemigodini kunye nobubanzi bombhobho wokuphefumla wemigodi ngokwesiseko lumgca ngolu hlobo lulandelayo:
C1 = ( a + bd) L(1)
Apho,C1- iindleko zokuthenga umbhobho wokungenisa umoya wam, CNY; a– ukonyuka kweendleko zombhobho wokungenisa umoya womgodi ngobude beyunithi nganye, CNY/m;b- i-coefficient yeendleko ezisisiseko zobude beyunithi kunye nobubanzi obuthile bombhobho wokungenisa umoya womgodi;d- ububanzi bombhobho we-ventilation yemigodi, m;L– Ubude bombhobho wokungenisa umoya wemigodi othengiweyo, m.
1.2 Iindleko zemingxuma yokungena komoya kwimigodi
1.2.1 Uhlalutyo lweeparamitha zokungenisa umoya wendawo
Ukuxhathisa komoya kumbhobho wokungenisa umoya wemigodi kubandakanya ukuxhathisa umoya wokukhuhlanaRfvUmbhobho wokungenisa umoya wasemgodini kunye nokumelana nomoya wasekhayaRev, apho ukuxhathisa umoya wendawoRevibandakanya ukumelana nomoya odibeneyoRjo, ukuxhathisa umoya kwengqinibaRbekunye noxhathiso lwemibhobho yokungenisa umoya emigodiniRou(uhlobo lokucinezela) okanye ukuxhathisa umoya wokungenaRin(uhlobo lokukhupha).
Iyonke ukuxhathisa komoya kumbhobho wokungenisa umoya ocinezelayo womgodi kukuba:

Iyonke ukuxhathisa komoya kumbhobho wokuphuma komoya womgodi wokuphuma kuku:
(3)
Apho:
Apho:
L– ubude bombhobho wokungenisa umoya womgodi, m.
d– ububanzi bombhobho wokungenisa umoya wemigodi, m.
s- indawo enqamlezileyo yombhobho wokungenisa umoya wemigodi, m2.
α– I-Coefficient of friction resistance of the duct ventilation duct yasemgodini, N · s2/m4.Uburhabaxa bodonga lwangaphakathi lombhobho wokungenisa umoya wesinyithi bufana ngokulinganayo, ngoko keαixabiso linxulumene kuphela nobubanzi.I-coefficients yokumelana ne-friction yazo zombini i-flexible ventilation ducts kunye ne-flexible ventilation ducts kunye nezangqa eziqinileyo zihambelana noxinzelelo lomoya.
ξjo- i-coefficient yokuchasana yendawo yendawo yokudibanisa i-vent ventilation joint, i-dimensionless.Xa kukhonamalungu kubude bonke bombhobho wokungena umoya womgodi, i-coefficient yokumelana neendawo ezidibeneyo ibalwa ngokwenξjo.
n– inani lamalungu ombhobho wokungenisa umoya wemigodi.
ξbs- i-coefficient yokuchasana kwendawo ekujikeni kombhobho wokungenisa umoya wemigodi.
ξou- i-coefficient yokuchasana yendawo kwindawo yokuphuma kwi-duct ye-ventilation duct, thathaξou= 1.
ξin-I-coefficient yokumelana nendawo kwindawo yokungena kumbhobho wokungena umoya womgodi,ξin= 0.1 xa i-inlet ijikelezwe ngokupheleleyo, kwayeξin= 0.5 - 0.6 xa i-inlet ingajikelezwanga kwi-angle echanekileyo.
ρ– ukuxinana komoya.
Ekungeneni komoya kwasekhaya, ukuxhathisa komoya kukonke komjelo wokungena komoya womgodi kunokuqikelelwa ngokusekwe kuxhathiso lulonke lokukhuhlana komoya.Ngokuqhelekileyo kukholeleka ukuba isixa soxhaso lomoya wengingqi wejoyini lombhobho wokungenisa umoya wasemgodini, ukuxhathisa komoya wasekhaya wokujika, kunye nokuxhathisa komoya kwindawo yokuphuma (uxinzelelo-uhlobo) okanye ukuxhathisa umoya wokungena (uhlobo lokutsalwa) Umjelo wokungena komoya wasemgodini umalunga nama-20% oxhathiso lulonke lokukhuhlana komoya kumbhobho wokuphefumla wasemgodini.Ukuxhathisa okupheleleyo komoya kwindawo yokungena komoya yasemgodini yile:

Ngokutsho kweencwadi, ixabiso le-coefficient yokumelana ne-friction α ye-fan duct inokuthathwa njengento eqhubekayo.Iαixabiso lombhobho wokungenisa umoya wensimbi unokukhethwa ngokweThebhile 1;Iαixabiso le-JZK series FRP ventilation duct ingakhethwa ngokweThebhile 2;I-coefficient yokumelana nokukhuhlana kombhobho wokuphefumla oguquguqukayo kunye nombhobho wokuphefumla oguquguqukayo kunye nohlaka oluqinileyo lwamathambo lunxulumene noxinzelelo lomoya eludongeni, i-coefficient yokumelana nefriction.αixabiso lombhobho wokungenisa umoya oguquguqukayo unokukhethwa ngokweThebhile 3.
