I am trying to simulate a solar thermal system which is coupled with absorption chiller in EnergyPlus!. Absorption chiller will supply chilled water into a collector to meet the cooling demand. Which object should I use to get the absorption chiller's cooling load?

I decide to use Coil:Cooling:Water but this object requires an air flow. However in my system, chilled water will be used directly as water in process cooling but I do not add the process cooling loop, as you can see the loops below I would like to get only chillers output energy under the identified conditions in software.

Thanks in advance!
