Re: [TRNSYS-users] Chilled Ceiling QCOMI

[David BRADLEY <d.bradley@tess-inc.com>]

My understanding is that QCOMI is the total energy crossing one or more inside surfaces in your zone. I am not sure whether you are taking into account QCOMI from all the surfaces in your zone or whether you are just looking at the ceiling. There are also internal gains, solar gains, etc. coming into the zone as well.

Hi,

 

Something wrong is happening when I run my simulation with a chilled ceiling. Until now I though the output QCOMI was the energy from the room to the wall and it should be similar to the demand of cooling of my room. Why are so different QCOMI and the theorical calculation:

 

Energy = flow_ceiling*cp_water*(Texit_water-Tentry_water)?

 

THanks
