Step 6 Step 7 Step 4 Step 5 Calculate the inlet air flow rate Q1, and check the compressed air supply capacity. Step 2 Correction of the outlet air flow rate influenced by the inlet air temperature (When the inlet air temperature is 25°C, proceed to S t e p 4 ) Check the purge air flow rate. Model selection based on corrected outlet air flow rate When the inlet air temperature is not the same temperature (25°C) on the performance charts, calculate the correction factor for the outlet air flow rate from the table below to compensate the outlet air flow rate. Read out from the purge air flow-rate characteristics on page 9. Based on the corrected outlet air flow rate calculated by , select a model from the performance charts on pages 5 and 6. Example: From the table below (Inlet Air Temperature . Correction Factor for Outlet Air Flow Rate), Inlet air temperature 35°C correction factors for outlet air flow rate are as follows. Series IDG�ｮA: 0.86 Series IDG: 0.40 Therefore, corrected outlet air flow rate can be determined. Outlet air flow rate 150 L/min [ANR] [Series IDG�ｮA] 150 ÷ 0.86 = 175 L/min [ANR] [Series IDG] 150 ÷ 0.4 = 375 L/min [ANR] Example: Inlet air pressure 0.5 MPa Selected model IDG30A For the IDG30A 45 L/min [ANR] IDG50HA For the IDG50HA 38 L/min [ANR] IDG60 For the IDG60 94 L/min [ANR] Inlet air temperature (°C) Inlet Air Temperature . Correction Factor for Outlet Air Flow Rate Note) Correction factors between Series IDG�ｮA and Series IDG are different from each other, because the membrane module characteristics are different. With the conditions of the corrected outlet air flow rate and the inlet air pressure mentioned to the left, when selecting a model which satisfies the specifications that the outlet air atmospheric pressure dew point .15°C or less, [Series IDG�ｮA] IDG30A, IDG50HA [Series IDG] IDG60 Example: Corrected outlet air flow rate 175 L/min [ANR] [Series IDG�ｮA] Corrected outlet air flow rate 375 L/min [ANR] [Series IDG] Inlet air pressure 0.5 MPa Outlet air atmospheric pressure dew point .15°C Series IDG�ｮA Series IDG 10 15 20 25 30 35 40 45 50 3.00 2.17 1.52 1.00 0.65 0.40 0.25 0.19 0.14 1.35 1.22 1.10 1.00 0.92 0.86 0.80 0.75 0.70 Step 3 Inlet air flow rate Q1 (L/min [ANR]) = Outlet air flow rate (L/min [ANR]) + Purge air flow rate (L/min [ANR]) Example: Assuming that the IDG30A is chosen Inlet air flow rate Q1 = 150 + 45 = 195 L/min [ANR] by Outlet air flow rate 150 L/min [ANR] Purge air flow rate 45 L/min [ANR] Compressed air supply capacity Q 300 L/min [ANR] Step 4 Step 6 Step 1 NO Review the operating conditions.
