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 some one tell me why if the optimun COP is at 0.25
