Re: [EnergyPlus_Support] Aquifer, thermal storage / heat exchange



Dear E+ support group,

For one of the LEED project, we are asked to model Aquifer Thermal Energy Storage (ATES) system. The ATES system consists of two doublets connected to hot and cold wells. During summer time, cold well provides cooling to the building and all drained heat is stored in hot well. During winter, water from hot well is cooled by cooling towers and cold well gets regenerated.

So far I have implemented Brent's suggestions above of using PlantComponent:TemperatureSource in combination with HeatExchanger:FluidToFluid. If any one has experience of modeling such system for LEED, would appreciate if they can share their experience here,

Thanks,
Chandan

Version 8.0 has added a couple new features that should help for this.

 

PlantComponent:TemperatureSource provides an open, once thru, generic source for plant fluid where the temperature can be scheduled. See example file PlantComponentTemperatureSource.idf

 

HeatExchanger:FluidToFluid  can handle either hot or cold water loops with a variety of control options, see example files PlantLoopChain*.idf

Subject: [EnergyPlus_Support] Aquifer, thermal storage / heat exchange

 

 

Hello,

My intention is to simulate a aquifer thermal storage / heat exchange system. With both a cold and a warm-source. I was hoping anybody could point me into the right direction? Or perhaps share an example idf?

I've been looking into the GroundHeatExchangers.
At first I thought the GroundHeatExchanger would be good approach. However since it uses a closed loop and a constant ground temperature, I'm not to sure about using this system...
The pond heat exchanger looks more promising to me. It would be great if I could switch off the above surface calculation part (e.g. evaporation and solar radiation) and use two ponds (one warm and one cold). However? it seems this isnn't possible?

Any help / hint / advice is highly appreciated.

Thanks in advance!

Dolf Bakker
