How to use 1 – Calculation Result Page –

When press “GET STARTED!” button, screen will shift to Calculation Result Display as above.

This display indicate the calculation results based on initial parameter when App has just started.

And just press “INPUT” button for calculatingsingle air condition. Switch on “Mixture Calculation” switch and input air flow amount of first air if you need to calculate mixture condition of two different type air.

How to use 2 – Single air calculation –

In case of single air calculation, press “INPUT” button. And this Input dialog will appear.

Please put Dry Bulb Temperature and either Wet Bulb Temperature,Due Point Temperature or Relative Humidity. And just switch on if you want to calculate this air under Cryohydrate condition.

Press “CALCULATION” button after input all parameter and calculation result will appear on “Calculation Result” page.

How to use 3 – Mixture air calculation –

Once you calculate single air condition, you can calculate mixture calculation of calculated air and other air which have different properties.

After switch-on the “Mixture Calculation” switch and input Air flow of calculated air, you can press “MIXTURE” button.

Then “MIX AIR PARAMETER” dialog will appear and you can input second air parameter including air flow.
