integral of fluxes ( status of last calculation)

[jorne]

Hi, I have other question, that is:

in the status of last calculation, I do not understand why there are 2 flux, a left side and one right side, and because it has different values?, I thought that heat flux has only one direction, in each case?

2- In the case of units in MJ/m2,M is Mega ?, ie: MJ = 1x10 ^ 6 J

3-in a case where I chose to indoor climate the EN13788 option with inside temperature = 20 ° C, what is the total amount of energy flow that crossing the wall ( and the outdoor climate is Lisbon climate file))??, where I can find it in Wufi?




thanks for your attention

1) The energy difference between inside and outside is due to two effects. First, the wall can safe some energy, second is energy needed for drying out the construction, so it goes into it, but does not leave again.

By the way: The positive direction is headed to the right. Take the interior surface. Positive means going into the room. Negative into the construction.

2) Right, M is mega

3) I´m not sure if I understand you right, but the interesting value is the right one, the energy what is going from the room into the construction.
The hourly values you can find in the ASCII-Export options (fluxes).
