<br>
I'm currently learning the use of TRNFLOW. To make it simple, I designed a 1m3 box with SketchUp.<br>
In TRNSYS:<br>
- Firstly I just observed the air temperature inside the box without any incoming thermal perturbation<br>
- Secondly I set up a large opening (window) with an opening schedule.<br>
<br>
The result is:<br>
In the second case, I do observe a dramatic decrease of the temperature inside the box when the window is opened. However, right after it is closed, the temperature "jumps" to the temperature in the first case. To say it briefly, when I put the two graphs together, the only difference is when the window is opened. For the rest, it matches almost perfectly.<br>
<br>
It shouldn't be like that since the outside air temperature is far below the inside temperature. I expected the same temperature in both cases before the windows is opened. Then a dramatic decrease of the temperature when the window is opened. And after closing the window, I expected the temperature to slowly decrease according to the outside air temperature, keeping a temperature difference between the two cases.<br>
<br>
Do you have any idea of the problem?<br>
(there is not heating in my model)<br>
