I have some question

I am analysisng about ventilation system

Dress room has dryer and dryer just can operate about internal air cleaning

We wanted to ventilate (external air cleaning) So, we thoght that it is able to ventilate by using ventilation system where is toilet

But this method has a problem.

Actually, The ventilation system where is toilet can operate "120[cmh]" in 'strong mode'

If we use toilet's ventilation system to ventilate dress room, ventilation performance is likely to be reduced.

So I interpreted it as the following steps:


1. I interpreted just "ventialtion system in toilet" for comparison with experimental values. And I got 119 [cmh].

2. I interpreted "ventilation + dryer". I used "inlet condition is inlet total pressure" and "outlet condition is outlet mass" to use initial condition.
[dryer not work, just ventilaton work]

3. I again interpreted to get mass's result of outlet.
I used "inlet conditon is Opening press. and Dirn" and "outlet condition is Average static pressure". I monitored outlet surface to see mass
[I used "Opening press. and Dirn" about Inlet condition instead of "Inlet total pressure" because of warning massage that Inlet is blocked]

4. final result was "26[cmh]

When I analyzed, I thought that the result is not realistic because Del P just is "30 [Pa]".
I think that The flow rate has been reduced by 10 times, but the pressure difference is too small

So, I have doubts about flow condtion.

The dress room is closed, but the opening pressure condition makes it an open condition.

So, I thought It could generate difference of results

Do you agree?

After analyzing once, when the analysis results are used as initial values, can the results be different in inlet total pressure and opening pressure?

I am so confused. So I want to get advice
