HeatPumps



Hi all,

 

I am modeling a water source heat pump system and can't seem to find out
where this excess miscellaneous/auxillary energy is coming from.  I have
determined that it is definitely coming from the heat pump system in
question.  When I look at the PS-C report and compare the energy of the
two pumps assigned to the system with the total energy listed on the
electric meter that I have the system assigned to, the total on the
meter is almost twice as large as the combined pump energy.

 

I can't for the life of me figure out what else in the SYSTEM = HP type
system could be contributing to the pumps/aux category.  Has anyone else
noticed this?  Am I missing something?
