Re: [EnergyPlus_Support] Re: cop and iplv values of a chiller, also i have the part load performance

Francesco,

Are you talking about the CurvefitTool?

Located here: "C:\EnergyPlusV8-1-0\PreProcess\HVACCurveFitTool\CurveFitTool.xlsm"

(obviously replace the C:\EnergyPlusV8-1-0 to where you have installed it)

Hello, I am not able to find theÂ spreadsheet that "leads you to obtain the three curves after providing the performance chiller data values". Could you help me, please?Â
I know the EER and the ESEER of a chiller (ESEER is the "European version" of the IPLV) but I have troubles calculating the coefficients of theÂ EIRFPLR curve. I read at the following link that is more complicated than I thought:Â http://energyplus.helpserve.com/Knowledgebase/Comments/Submit/61/

Hi,
You can read the documentation,the engineering reference pdf file.It has the chiller models very well explained.
I have also uploaded an spreadsheet to the yahoo group which leads you to obtain the three curves after providing the performance chiller data values.
I hope this can help you.

dear,
Good day,
I have the cop and iplv values of a chiller, also i have the part load performance values of
EEFTÂ Evaporator entering fluid temperature
ELFTÂ Evaporator leaving fluid temperature
CEFTÂ entering condenser water temperature
CLFTÂ leaving condenser water temperature
CAP (ton)
PCT Power
kw/TR
for each part load(15,20,30...100%)

I dont know how to set it or how to transform it to can set this values in energy+, i think that the program could generate a curve with only COP and IPLv but i havent cant find that. Also i have tried to use Chiller:EIR and the EIRPLR curve is:

Â EIRFPLRÂ Â y = 1.9927x2 - 1.9632x + 1.0078
RÂ² = 0.9499

i dont know if it is correct, also i dont know set up the other 2 curves because both are for full load, well, i think that because there ae onl function of temperatures.

thank you in advance.
