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
– 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
