modelAbsorptionIndirectSteamVaryingLoad
Absorption chiller with varying cooling load
Information
This model validates Buildings.Fluid.Chillers.AbsorptionIndirectSteam. for the case with varying cooling load.
The model is constructed in a way that the temperatures which determine the performance of the absorption chiller are kept constant in order to monitor the effects of the part load behavior on the ratio of the provided cooling to the required steam.
