| Dear TRNSYS users, I have a question regarding the modelisation of radiant ceiling (in this case to cool a room). I have found in the TRNSYS manual that we can use a specific layer (called cooled ceiling). I have some troubles though to figure out what some parameters are about. For pipe spacing and inside diameters that's quite obvious, same for specific norm power. - But when you sau "specific norm massflow" is it different from the massflow we can indicate in the "specification" of the roof (ie : the inlet massflow). - What about the norm area ? Is this supposed to be the area of one radiant panel ? how do you know the number of panels then ? how does it relate to the area of the roof ? - What about the number of loops ? how is it different from the number of fluid loops that we indicate in the specification (new button that appear in the wall definition window) - what about the Urwx coefficient ? I've read the help document (also availaible when clicking on info) but I really don't get it ... according to the button we tick, the result is different. Is it a specificity of the radiant ceiling (assuming we have a tipical roof above ? - what is the influence of the airgap ? Then, when the modelisation is done, and running, is it possible to know the temperature of the outlet (every hour) as well as the cooling power that it represents ? thank you for your answer Best regards Julie Julie LESTRADE |
