- Air Changes Per Hour(ACH) = (CFM x 60) / Room Volume ft3
- CFM = Room Volume ft3 x (Air Changes Per Hour / 60)
- %OA = (RAT - MAT) / (RAT - OAT) x 100
- OAT = (MAT x 100) – (%RA x RAT) / %OA
- MAT = (%OA x OAT) + (%RA x RAT) / 100
- RAT = (MAT x 100) – (%OA x OAT) / %RA
- QTOTAL(Btu/Hr) = 4.5 x cfm x Δh(Btu/lb)
- Cooling Load(tons) = 4.5 x cfm x Δh(Btu/lb) / 12,000
- QLATENT(Btu/Hr) = .68 x cfm x ΔW(grains/lb)
- Humidification Load(lb/Hr) = 4.5 x cfm x ΔW(grains/lb) / 7,000
- QSENSIBLE(Btu/Hr) = 1.08 x cfm x ΔT(oF)
- Electric Heat Capacity(KW) = 1.08 x cfm x ΔT(oF) / 3,414
- Gas Heating(MBH) = 1.08 x cfm x ΔT(oF) / 1,000
