I am a master student in Brazil. In my work I am simulating a model with 2 rooms and 1 hall that have the mixed-mode system (natural ventilation when is possible - Tsetpoint = 18ºC<T<25ºC, and when the conditions are not favorable the conditioning air is turned on - Tsetpoint >= 25ºC.
I have doubts, and I need some help in the following itens:
1) The modulation of the window is not good for this type of system (mixed-mode), and I want know if it is possible to cancel this modulation. So when the window opens, the window total area will be destined to ventilation, with no windows modulation.
2) Another problem, it seems like there are no infiltration in the room, so the inside temperature is very high. I want to know how can I input a value of the infiltration with the Airflow Network group, our create a extra leak in doors or windows for permiting this.
