[TRNSYS-users] Strange part-load data for Type655

Hello.

I find that the sample part-load data for Type655 (air-cooled chiller) as shown
below seems very strange.

0.0  0.25  0.50  0.75  1.00	           ! Part Load Ratio
0.0000			           ! Fraction of Full Load Power at PLR=0.00
0.0902			           ! Fraction of Full Load Power at PLR=0.25
0.3241			           ! Fraction of Full Load Power at PLR=0.50
0.6262			           ! Fraction of Full Load Power at PLR=0.75
1.0000			           ! Fraction of Full Load Power at PLR=1.00

The fraction of full load power appears to be unreasonably small, especially
when the PLR is less than 0.5.  By applying the above part-load data, the
calculated COP becomes very large at low PLR.  Does anyone have another set of
data that can be shared?  Thank you!
