Ukubalwa Kwevolumu Yomoya Wokungenisa umoya kanye Nokukhethwa Kwezisetshenziswa Ekwakhiweni Komhubhe(2)

2. Ukubalwa komthamo womoya odingekayo ekwakheni umhubhe

Izici ezinquma umthamo womoya odingekayo ohlelweni lokwakhiwa komhubhe zihlanganisa: inani eliphezulu labantu abasebenza emhubheni ngesikhathi esisodwa;inani eliphezulu leziqhumane ezisetshenziswe ekuqhumeni okukodwa: isivinini esincane somoya esicaciswe emhubheni: ukuphuma kwamagesi anobuthi nayingozi njengegesi ne-carbon monoxide, kanye nenani lezinjini ezivuthayo zangaphakathi ezisetshenziswa emhubheni Linda.

2.1 Bala umthamo womoya ngokomoya ohlanzekile odingwa inani eliphakeme labantu abasebenza emhubheni ngesikhathi esisodwa.
Q=4N (1)
kuphi:
Q - umthamo womoya odingekayo emhubheni;m³/min;
4 — Umthamo womoya omncane okufanele unikezwe umuntu ngamunye ngomzuzu;m³/min•umuntu
N - Isibalo esiphezulu sabantu emhubheni ngesikhathi esifanayo (kuhlanganise nokuqondisa ukwakhiwa);abantu.

2.2 Kubalwa ngokwenani leziqhumane
Q=25A (2)
kuphi:
25 — Isilinganiso somoya esincane esidingekayo ngomzuzu ukuze kuncishiswe igesi eyingozi ekhiqizwa ukuqhuma kwekhilogremu ngayinye yeziqhumane ibe ngaphansi kwezinga elivumelekile phakathi nesikhathi esishiwo;m³/min•kg.

A - Inani eliphezulu lesiqhumane elidingekayo ekuqhumeni okukodwa, kg.

2.3 Ibalwa ngokwejubane elincane lomoya elishiwo emhubheni

Q≥V_iminithi•S (3)

kuphi:
V_imiz- ubuncane besivinini somoya esishiwo emhubheni;m/min.
S - indawo encane enqamula ingxenye yomhubhe wokwakha;m².

2.4 Kubalwa ngokuya ngokuphuma kwamagesi anobuthi nayingozi (igesi, i-carbon dioxide, njll.)

Q=100•q·k (4)

kuphi:

I-100 - I-coefficient etholwe ngokuvumelana nemithethonqubo (igesi, i-carbon dioxide ephuma ebusweni bomhubhe, ukuhlushwa kwe-carbon dioxide kungabi ngaphezu kwe-1%).

q — ukuphuma ngokuphelele kwamagesi anobuthi nayingozi emhubheni, m³/min.Ngokwevelu emaphakathi yamanani ezibalo akaliwe.

k — i-coefficient engalingani yegesi enobuthi neyingozi ephuma emhubheni.Isilinganiso sevolumu yokugeleza ephezulu ukuya kuvolumu yokugeleza emaphakathi, etholakala kuzibalo zangempela zokulinganisa.Ngokuvamile phakathi kuka-1.5 no-2.0.

Ngemva kokubala ngokwezindlela ezine ezingenhla, khetha leyo enenani elikhulu kakhulu le-Q njengenani levolumu yomoya edingekayo ukuze kungene umoya wokwakha emhubheni, bese ukhetha imishini yokukhipha umoya ngokwaleli nani.Ngaphezu kwalokho, inani lemishini evuthayo yangaphakathi nemishini esetshenziswa emhubheni kufanele kucatshangelwe, futhi umthamo wokungenisa umoya kufanele unyuswe ngendlela efanele.
