A computer-room air handler: a deep chilled-water coil and a draw-through plug fan, no outside air, no heater — a data hall is cooled all year. In the example data centre it breathes two halls' return air and takes 14 °C water from the chiller block; the design point here is at 14 °C too. Published as an example; the figures below are solved from this model, not copied from a datasheet.
