The Type 504 model is a water-to-air heat pump model; transferring energy 
between the working fluid (typically water) and an air stream.  In cooling 
mode, the water stream acts as the heat sink (condenser); rejecting energy 
from the air stream cooling process and the compressor heat.  In heating 
mode, the water stream acts as the heat source; adding energy from the 
fluid stream and compressor energy to the air stream.

We also sell an air-to-air heat pump model and a water-to-water heat pump 
model in the HVAC component library addition for TRNSYS.  I can provide 
details if you are interested.

I hope this helps,

Jeff
