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
