Among many queries, I have the answer about how to model and account for various degrees of opening of a operable window? The operable window can be model in the AirflowNetwork:Multizone:Component:DetailedOpening objective, under the Airflow Network group. In this objective upto maximum four sets of opening factor data for each window can be given to control the opening state of a window. However, It should be remember that the opening factor-1 and opening factor-4 should be 0 and 1 respectively. Opening factor 0 and 1 respectively mean that the window is completely closed and open. In the opening factor 2 and 3 any value greater than 0 and less than 1 can be inserted depending upon the user requirement. For example if the value of opening factor-2 is 0.5 then the model will assume that the window is half open. Best Sankar |

| 2016-05-23 10:46:40 -0500 | asked a question | What minimum size of thermal zone can be simulated in E+? I am using E+ for the thermal simulation of a room having double skin facade (DSF) in south direction. In order to determine the temperature of each surfaces of the DSF and more, I have considered it as a separate thermal zone. However, the size (HxLxW) of this thermal zone is only 250x180x1.3 cm. Here 1.3 cm is air cavity thickness between two facades. In the literature thermal zone of size (HxLxW), 20x170x20 cm can found where E+ has been used (example). The question is up to what minimum zone size the E+ can simulate accurately? Is there any reference document in this regards? The considered thermal zone has natural air flow facility. |
