Dear Lukasz, for stratifications you can use coupling. In Trnsys 17 you can only connect two airnodes within a zone. In Trnsys18 up to 6 airnodes can be coupled. The airflow between airnodes is a
user input. Please have a look into manual 05-MultizoneBuilding: 5.2.4.10. Coupling between airnodes of same zone (T17) or 5.2.7.10. Coupling between airnodes (T18) In Radiation Modes of Thermal Zone you can set a Solar to air factor. Please have a look into manual 05-MultizoneBuilding: 5.2.4.12. Radiation Modes (T17) or 5.2.7.12. Zone Radiation
Modes (T18) The solid gets the heat from the source of heat by longwave radiation (Depends on the model you are using. Please have a look int o05-MultizoneBuilding: 5.2.4.12. Radiation Modes (T17)
or 5.2.7.12. Zone Radiation Modes (T18)) and indirectly also by convection/heat conduction. Regards, Christoph Von: TRNSYS-users <trnsys-users-bounces@lists.onebuilding.org>
Im Auftrag von Lukasz Watly via TRNSYS-users Dear All, I am writing to you with some questions that appeared while working on the model in TRNSYS. I am preparing a model of 3-storey building with low-temperature floor and ceiling heating installed. I am interested in doing the vertical stratification on each and every floor of this building, meaning that I would like to have at least 4 different nodes on the given floor. Is it possible
to do the stratification in this way with TRNSYS? If so, how could I approach it? Next problem regards the aspect of radiation. As each air node represents each zone, the air normally does not receive any radiation heat, but the solid does. However, in the tutorial it is
mentioned that air node receives heat radiation. My question is how does it happen in more details? I would be grateful if somebody could share his/her knowledge. Thank you in advance for your help. I look forward to hearing from you. Kind regards, Lukasz Watly |
