CHP + Absorption Chiller

asked 8 years ago

41 ●4

updated 8 years ago

I completed a model using the following element (and all the related objects):

One AirTerminal:SingleDuct:VAV:HeatandCool:Reheat
Boiler:HotWater
Chiller:Electric:EIR
CoolingTower:TwoSpeed
WaterHeater:Mixed

The model run correctly and this is the basic case, now I want to implement a model that use a Internal Combustion Engine and an Absorption Chiller to cover the basic load. I will resize the Boiler and the Chiller to cover the peak load.

I completed the model with CHP and Absorption Chiller but I have a problem: the CHP always work at 100% and if I size it in a way that it cannot work at 100% for all the time the simulation fail (error on maximum temperature over the limit in the hot water loop).

Any idea on what I can do to fix this problem?

Thank you!

Andrea

I correctly modeled the system, but the Absorption Chiller don't work to cover the basic load as I indicate in the PlantEquipmentList (first listed). There is a way to impose that the Absorption Chiller must work to cover the basic load?
