Dear all,
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 a change in building aspect ratio the aspect ratio of the building from 1:1 to 4:1. The building with a 1:1 aspect ratio is 20m * 20 m * 3m and the building with a 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 an aspect ratio of 4:1 from 1:1 should increase more. Why is it just 4%?
This work could help you to optimize the roof cooling:
