Lixing Gu, I am simulating the natural ventilation. I am using the value of 0.08 for air mass flow coefficient when opening is closed. I got this value on AIVC book - Lidament. But I noticed that on examplefiles that this value is 0.001. I simulated with both values and the final results are very different. The air changed is higher in the case that I used 0.08. Am I wrong to use 0.08 value? I did not find where in the Input/Output or Engineering that is saying I have to use the Zone/Sys Air Temperatute to activate natural ventilation. Can you help me?? Thanks for all, Ana Paula. |
