Gaston and Rodrigo:

Some information below from Mitsubishi.  Joseph is trying to get the proper 
information for your models and I will forward it as soon as I get it.  He 
attached generic curve data.

Paul,
 
This product is international and potentially a Mitsubishi Heavy Industries 
product (not to be confused with Mitsubishi Electric, they are actually 
competitors in certain parts of the world).  From the model nomenclature, it 
appears to be a 125 ton system, but I have not yet been able to locate any 
documentation to confirm this.  Would you happen to know what country this 
product is being sold in?  This would help me in locating literature.
 
With regards to custom curves, I assume you are putting together an energy 
model.  Below are generic heating/cooling capacity/power input curves that can 
be applied across the board to Mitsubishi’s inverter driven heat pumps (the 
factors are a fraction of nominal, “PLR” is capacity, “Power” is power input).
 
 
Cooling Part-load Performance:
 
 
PLR Power 
0.25 0.3026 
0.5 0.4487 
0.6 0.5385 
0.7 0.6154 
0.8 0.7179 
0.9 0.8462 
1 1 
1.1 0.9872 
1.2 0.9744 
 
 
 
 
Heating Part-load Performance:
 
 
PLR PWR 
0.25 0.3211 
0.5 0.5263 
0.6 0.625 
0.7 0.7105 
0.75 0.75 
0.8 0.8026 
0.9 0.8947 
1.0 1 
1.1 0.9737 
1.2 0.9474

Joe:
 
I wonder if you can help me out.  I am looking for the performance data for a 
PUHY-P1500-YSHM-A.  I want to write the custom curves for this unit.  I guess it 
is not sold in the USA?  This is a project in another country.
 
Thank you,
