[EnergyPlus_Support] Absorption chillers: condenser water problem

["iriematt@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

Hi all,

 

Is anyone familiar with the Chiller:Absorption object? I'm having trouble with the condensing side of the absorption chillers. The condenser water system inlet/outlet temps are constant at 70F (21C) year round. The condenser water system annual cooling rate is zero. The chiller condenser annual heat transfer is zero. The chilled water inlet/outlet temps look fine, although I don't see how that's possible without a properly operating condenser water system. Any ideas what's the problem here?

 

The original model used two electric chillers and it ran fine with a functional condenser water system. I replaced the electric chillers with two absorption chillers and used the same nodes, etc. I added district heating for the chiller generator loop. Almost everything else is the same between the two models.

 

Thanks,
matt.
