IB FluidCoolerTwoSpeed

The two-speed fluid cooler is modeled in a similar fashion to the single-speed fluid cooler. The fluid cooler is modeled as a cross flow heat exchanger (both stream unmixed) with two-speed fans (induced draft configuration). The user must define fluid cooler performance via one of two methods: heat transfer coefficient-area product (UA) and design water flow rate, or nominal fluid cooler capacity at a specific rating point. Regardless of which method is chosen, the airflow rate and corresponding fan power at both high and low fan speed must be specified. The Fluid Cooler seeks to maintain the temperature of the water exiting the Fluid Cooler at (or below) a set point. The set point schedule is defined by the field Condenser Loop Temperature Setpoint Node Name or Reference'' for the CondenserLoop object. The model first runs at low speed and calculates the fluid cooler exiting water temperature. If the exiting water temperature based on low speed'' is at or below the set point, then....
