HI,

In a 80T scroll chiller water plant (only one chiller), 3 Variable speed AHU in Barranquilla Colombia, the chiller has a reference COP= 3.5 an condenser temperature ref=95°F, optimum COP =0.25

The size of AHU are good, the chiller size is good, but in the simulation the chiller COP is lower at low capacities, can someone tell me why if the optimum COP is at 0.25, at lower capacities must be lower COP, i would expect Higer COP than 3.5 at 50% because lower outdoor temperatures and less capacity.

How can i attach an osm file?
