Useful Formulas

– 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
