Re: [TRNSYS-users] help for cooling load in type 56
Dear Meltem,
The sensible cooling load calculated by Type56 is the amount of energy
that must be extracted from the space in order to keep it at the
temperature that you have specified (25 C in your case). If you want Type56
to report 0 cooling load when the building is not occupied, you have a
number of options. You could write an equation in your input file that
multiplies the Type56 reported cooling load by 0 whenever the building is
not occupied. Alternatively, you can define a SCHEDULE in Prebid (or
TRNBuild for those of you using TRNSYS 16) that sets the available cooling
capacity of the building to zero whenever the building is not occupied. A
third alternative is that you can set an unrealistically high cooling set
point temperature (100 C for example). That will insure that your building
would not naturally reach the cooling set point temperature and would
therefore not require any cooling energy.
Kind regards,
david

Dear Trnsys users,
I am a masters student and just started using Trnsys. I want to calculate
cooling load for my 5-zone building with Trnsys 15 using IIsibat3. I ve
defined my building in Prebid and set up the model in IIsibat using Type
56. I defined set temperatures for my cooling system 25 C in Prebid as
COOLING. I want my model to calculate cooling energy only for occupied
hours like 8.0-18.00. When i run the simulation it calculates it for the
whole season.
How can i achieve to get right results
Any help would be appriciated
Thank you in advance
Meltem
