Abstract
A chiller system includes at least two refrigerant circuits. In a low ambient temperature condition, only one refrigerant circuit is activated, but its condenser fan is de-energized. To provide some airflow across the condenser of the activated circuit, a condenser fan of the inactive circuit is energized. A small air duct allows the condenser fan of the inactive circuit to draw a low volume of air across the condenser of the active circuit.
