| Hi, I'm trying to simulate a model with a chimney to increase the natural ventilation, but this chimney have two sections, the first with a solar collector and the second as a convencional chimney, I'd like to know how criate this model and how to group these sections. In the Examplefiles, there is a idf with thermal chimney, but the solar collector occupies all the area of the chimney and the chimney is only thermal. thanks |
