Re: [EnergyPlus_Support] "Rating Conditions" for Water to Water Heat Pumps



Chandra,

Thanks a million!  I missed that the rated conditions are also included in the excel spreadsheet.

Jim - I just got a response from the manufacturer that there is currently no official "rating condition" for these units!!  No wonder I couldn't find anything on such a rating.

Also, these "Rated" conditions are same which user specifies in the E+ object. (absolute page 107/196 of the attached document or link below)

Dear Karen,

 

?Rating? conditions are normally the AHRI test conditions. For typical DX coils, these are 95F outdoor, 80F dry bulb / 67F wet bulb coil entering temps.  I am not sure about the conditions for heat pumps.
