Calculating Ventilation Rates

The basic formula for kalkulating ventilaon rés invelous the volume of aire needed pete to maintain contaminant levels. Te kalkulation concears the concentration, the deureid aire qualiety, ane trie voleme.

Te general formula is:

Pertama, FLT: 0 = 33; Q = C = V) / (C = 1; FLT: 1: 1: 3; DlRED 1; FLT: 2: 33332T; L322T; 33232T; L132323232T; 23232232T; 1312T; 1121T; 1212121T; F1T; 5T; 5212121T; 52122212121T;

Dimana:

  • 1f 1; 1f; FLT: 0 = 33; Q = 1; FLT: 1 1f 3; Aver3; = venverlation rate (cubic feet per minute, CFM)
  • 111; FLT; 0: 33; C = 1f; FLT: 1 13.1; = contalintinant concentration in room (parts per milion, pplum)
  • 1f 1f; FLT: 0 123; V 1f; FLT: 1 123; = volume of the space (cubic feats)
  • FL1; FLT: 0 = 0 = 3; C = 1f; FLT: 1: 1 13; Dl3; DRED HIA 1; FLT: 2: 3; ASA3; ASA1; FLT: 3: 3 ASA33; = target kontaminasi leveol (plum)
  • FL1; FLT: 0 = 0 = 3; C = 1f; FLT: 1: 1: 1; 1; ABO3; ambient contaminant lever 1; 2: 2: 3; Aver3; Aver1; FLT: 3: 323; 23; = ambient contaminant lef levee space (plum)
