Re: [EnergyPlus_Support] Heat Pump Modelling

The spreadsheets are available in the Yahoo Groups files.

The input files are included with the EnergyPlus installation.

I will let you know when they are available.

Thanks,

Edwin,
 
Can you send both fow water to water and air to water HPs? Are there seperate excel sheets for reciprocating and scroll compressors, as I believe the required parameters for these two compressor types are different. If yes then I am interested in both compressor types.
 
Thanks and Best Regards,
 
Saqib

Saqib:

The parameter estimation procedure involves a simulation of the heat pump.  A spreadsheet (Excel) tool was available from the Oklahoma State University website, but has been removed (I believe it was left behind during a website update).  A new tool is currently under development which is not spreadsheet based, but a standalone program.  I will look into getting a copy of the spreadsheet tool put back online until this new tool is available.  For reference, will you be using Water to Air or Water to Water heat pumps?

Jay:

There are a few example files which use these parameter estimation heat pump models.

Water to Air:
5ZoneWaterLoopHeatP ump.idf
5ZoneWLHPPlantLoopT ower.idf
HeatPumpWaterToAir. idf
HeatPumpWaterToAirW ithAntifreezeAnd LatentModel. idf
HeatPumpWaterToAirW ithAntifreezeAnd LatentModel. idf

Water to Water:
GSHP-GLHE.idf
PlateHeatExchanger. idf

Dear Sankar,
 
Actually I have conatcted Jin regarding the parameter estimation procedure. Please do explain how to estimate the parameters from the catalog dat. Please send the idf as I donät have it.

Hi Saqib,
The model is called HEATPUMP:WatertoWat er(or
watertoair): ParameterEstimat ion. Since you mentioned you are familiar
with the model, I assume you know how to derive the parameters for the
model.

Thanks
Sankar
