I have modeled a building in TRNSYS. I am cooling the building using the radiant panel on the roof integrated with simple cooling coil and other heat recovery devices (like enthalpy wheel, round around coil), for representing the radiant room.
I wanted to see the change in cooling load with change in building aspect ratio the aspect ratio of the building from 1:1 to 4:1.
The building with 1:1 aspect ratio is 20m * 20 m * 3m and the building with 4:1 aspect ratio is 40m *10m * 3m.
On doing so the cooling load of the building increased by around 4%.
In my opinion, the cooling load of the building with aspect ratio of 4:1 from 1:1 should increase more. Why is it just 4%?
I have attached the model with 4:1 as ew4isto1.zip and 1:1 as EW 1isto1.zip.
It would be great to get a comment about the way i have used the radiant chilled ceiling.
