Sambhav:

You cannot change straight shot system types or Package to CHW with parametrics per se. You need to create another separate file to use these new SYSTEMS/PLANT. Then in the parametrics run, you can call out the different file and run THAT files, with the results appearing in the Original run.

Others have probably done this more often than me..

Hi All
              I had one queary pertaning to equest  . I have a
packaged multizone system in my base case and for the proposed case i
want to go with a VAV system so when i went to parametric run and
clicked created parametric component there i went to HVAC system and
changed the system type to VAV in the list of options available but i
want to given number of chillers and 1 air and 1 water cooled along
with 1 cooling tower but all these options are not comming the the
list of parametric run then i should i proceed.

Second doubt in the wizard there comes one options as interior end use
contributing to cooling load.
and no of options are

interior ambient lighting

interior task lighting

office end use equipments

miscellaneos equipments

self cont referigerations

motors

process load

air compressors

Which among these all should i take as cooling load for the space(only
ambient light and off equipment or motors also) or what you suggest.
how will the cooling load in space  contributes due to pumps and fans
of HVAC system come in account.

I look for your response

Thanks
Sambhav
