[Equest-users] Heat Pump Efficiencies

[Daniel Deese]

Michael,

 

            Typically equest stores the efficiency of a given piece of equipment as either the Heat Input Ratio (HIR) or as the Electric Input Ratio (EIR).  This is under the "Equipment Efficiency" heading on the "Basic Specifications" tab if you open the equipment properties within the detailed interface.  The Electric Input Ratio should be the inverse of the COP.  I hope this helps.  Thanks.

Hi All,

 

I am still fairly new to equest and I am having a bit of trouble with setting up my HVAC.  I created a building model using the equest wizard and now I have made a number of changes within the detailed DOE2 interface.  The building uses air source heat pumps for the HVAC and I would like to change the EER/COP values without going back to the wizard, but I cannot figure where these values are stored.  Is there an easy way to make changes like that within DOE2?

 

Thanks,

Michael Shields
