Attic Zone Setting

Post by Alina0826 » Thu May 24, 2018 4:29 am -1100

Hello WUFI Team:

I am working on my master thesis for attic ventilation.

I have a question about zone setting.
For attic zone, I set it in the "simulated zone", and there are no internal load and HVAC set in this zone.
It's means no machine to control the area in some conditions.
In that case, how about "design conditions", how to set this one, the day profile is follow which schedule? Thank you!

if you regard a zone to be simulated, without an hvac device, the climate in that zone is not kept in the design conditions. The climate is free floating. For example if your min. design temperature is 20°C, and you have an heating device coupled to the zone, the temperature is kept at 20°C and the heating demand is calculated, which is necessary to keep the 20°C. However if you don't have a heating device the Temperture is calculated, also below that min. design condition temperature. If there are no internal loads, you dont' have to add some.
