[Equest-users] how to model steam absorption chiller in eQUEST

[John Aulbach]

Aaron:
 
Size the pump for the btus the chiller will require in hot water load, then set the pump kW to Zero. Pump will still work ,just not use any energy. You will need a steam boiler connected to the chiller, with probably a 100% efficiency. In that way, you are essentially firing the chiller with steam.

Subject: [Equest-users] how to model steam absorption chiller in eQUEST



Hi guys
     I'm modelling a steam absorption chiller, but seems not easy. I've set the chiller as below.  I set heating source as Hot water loop, because seems steam is not available for absorption chiller.
    

I set steam meter for steam source, 

but error appears after running the model saying absorption chiller must have a pump for absorption steam loop as below.
please, could anyone give some guide on this problem for me?

thanks

                             Aaron
