Chiller cooling capacity

Good morning,
Where do I have to insert the cooling capacity of a chiller? in the equipment
capacity (in the chiller properties) or in the process load (in the circulation
loop properties)?

thanx,
Lilach.

It's under "Capacity", see below (note you input MBtu/h or 100 ton=1.2
MBtu/h). If you leave it empty, eQUEST will autosize the chiller:

From the help file:

Volume 2: Dictionary
> HVAC
Components
> CHILLER
> Chiller Design and
Operating Capacity

CAPACITY

The cooling capacity of the chiller. The SPECIFIED-AT keyword indicates
whether the specified capacity is at the RATED-CONDITIONS or the
DESIGN-CONDITIONS.

If you do not specify CAPACITY, it defaults to the chilled water loop
capacity times CAPACITY-RATIO. If no CAPACITY-RATIO is input, the
capacity will default to the loop capacity divided by the number of
chillers attached to the loop.

Does anyone know how to report on the performance of the indirect app
of an evaporative cooler in eQUEST (and not just the DX coil)? Also,
does anyone have some evaporative cooling effectiveness curves
they've developed which they would be willing to share with me?

Thank you!
