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.
