Chiller Waterside Fouling Calculator

Calculate evaporator and condenser waterside tube fouling thermal resistance ($0.0001 ext{ to }0.00025 ext{ hr-ft}^2 ext{-}^circ ext{F/BTU}$) and approach temperature degradation ($Delta T > 3.0^circ ext{F}$): quantify the electrical energy penalty (each $1.0^circ ext{F}$ increase in condenser approach increases chiller energy consumption by $1.5% ext{ to }2.0%$), and automated tube cleaning system margins.
