FaultModel:Fouling:Chiller reduces the nominal capacity of the chiller. Referring to the Engineering Reference, the fouling factor is applied to the chiller capacity and the chiller COP. If the chiller has adequate capacity for the current load, the "Chiller Evaporator Cooling Rate" will be identical with or without the fouling factor. If the chiller is delivering the same load, but at a reduced COP, then the electric power consumption will be higher and the heat rejection to the condenser will be higher.
