Lüftungsmengen-Rechner (Personen / Fläche / Schadstoff)
Berechnet den Außenluft-Volumenstrom nach dem ASHRAE-62.1-Verfahren: Personenanteil Vpz=Rp·P, Flächenanteil Vaz=Ra·A, Atembereich Vbz=Vpz+Vaz, Zuluft Voz=Vbz/Ez. Drei Modi: ASHRAE 62.1 (Personen + Fläche), pro Person (P×Rp) oder Schadstoffverdünnung (Q=G/(C_acc−C_sup), G in mg/s/mg/h/L/s, Konz. mg/m³ oder ppm). Ausgabe in L/s, m³/h und CFM.
Floor area A, in the selected Area Unit. Used in 'ashrae' mode.

ez
number
Nein
Zone air distribution effectiveness Ez (0.1–2). Default 1.0. Typical: ceiling supply cool air = 1.0, warm air = 0.8, floor supply = 1.0. Used in 'ashrae' mode.
gGeneration
number
Nein
Pollutant generation rate G, in the selected Pollutant Unit. Used in 'contaminant' mode. For CO₂: ~0.005 L/s per person at rest.

molarMass
number
Nein
Pollutant molar mass M (g/mol), used to convert ppm ↔ mg/m³. Default 44.01 (CO₂). Only used when Concentration Unit = ppm in contaminant mode.
