Hiter Kalkulator pretoka zraka za podzemno prezračevanje
Quickly ocena required pretok zraka od delavec število, dizelski oprema število, moč, and condition factors.
This is a preliminary ocena for early planning, training, and comparison. It is not a substitute for final prezračevanje zasnova or regulatory compliance.
Safety opomba
Vsi izračuni ostanejo v tem brskalniku in se ne pošljejo na noben strežnik.
- For preliminary estimates, training, and comparison only. Not a substitute for final prezračevanje zasnova or legal compliance.
- Preglej gas, dust, heat naloži, oxygen deficiency, and post-blast dilution separately.
- Adjust dizelski condition factors to match lokacija standards and oprema maker guidance.
Kako uporabljati
Opombe
- Enter the delavec število for the area you want to ventilate.
- Dodaj one vrstica per dizelski oprema type and enter število, moč, condition faktor, and sočasnost.
- Odpri nastavitve if you need to change pretok zraka coefficients, minimalni pretok zraka, or decimal places.
- Preveri the prevladujoči merilo and the final priporočena pretok zraka in the rezultat pane.
Primeri
Vnos / Izhod
Case 2: 4 delavci / 1 service tovornjak / 30 kW / lokalno minimalni 120 m³/min
Vnos
Delavci=4, oprema=service tovornjak ×1, moč=30 kW, condition=controlled, sočasnost=100%, lokalno minimalni=120 m³/min, rezerva=10%
Izhod
About 2.2 m³/s / 132 m³/min / 4,700 cfm. Prevladujoči merilo: lokalno minimalni pretok zraka.
Slovar
Podzemni prezračevanje pretok zraka izračun
- Required pretok zraka
- The estimated amount of air that should be supplied to the podzemni working area.
- Prevladujoči merilo
- The largest requirement among personnel, dizelski oprema, and lokalno minimalni pretok zraka.
- Sočasnost
- The deli of oprema that is expected to deluj at the same čas.
- Condition factor
- A referenca faktor that reflects differences in oprema condition or aftertreatment.
- Rezerva rezerva
- An added percentage above the prevladujoči merilo to keep the ocena conservative.
Formulas
Internal izračuni uporabi m³/s as the base enota.
- Q_people = N_people × R_people
- Q_row = N_i × P_i × F_condition_i × F_simultaneity_i × R_diesel
- Q_governing = max(Q_people, ΣQ_row, Q_local_min)
- Q_design = Q_governing × (1 + reserve / 100)
- 1 m³/s = 60 m³/min = 2118.88 cfm
Pogosta vprašanja
Opombe
Can I uporabi this for final prezračevanje zasnova?
Ne. Namenjeno je predhodnim ocenam, usposabljanju in primerjavi. Končna zasnova mora slediti predpisom, standardom lokacije in strokovni presoji.
Does it podpora both m³/s and cfm?
Da. The prikaz can switch, and the internal izračun uses SI enote.
What does the condition faktor mean?
It is a referenca faktor for lokacija standards, aftertreatment, maintenance state, and similar differences.
What if there are multiple dizelski oprema types?
Dodaj vrstice and enter the število, moč, and factors for each oprema type separately.
Can I uporabi it offline?
Da. Deluje povsem v brskalniku in ne uporablja zunanjih API-jev.
Opombe
Internal izračuni uporabi m³/s as the base enota.
- To orodje zagotavlja referenčne izračune. Končna zasnova mora dati prednost lokalnim predpisom, internim standardom in pogojem proizvajalca.
- Adjust the condition and delavec coefficients to your lokacija assumptions.
- Enter only the oprema that actually runs at the same čas if you want easier comparisons.
