<font size="+1">Sorry about that, my reasoning was flawed, the
answer was not. Happens when you have a foot in the imperial and
metric camps and you don't pay attention.<br>
The performance of a cooling tower would be defined by the fluid
flow, the delta T of the water, the water side pressure drop and
the energy required to produce this effect. The efficiency of the
fan, the air flow of the fan, any other air side inefficiencies
and the motor efficiency is quantified by the energy consumption
of the motor. <br>

From 6.8.1G: For axial fan cooling towers, the performance
required is >= 3.23 L/s.kW. Below this table, it says
this: ''Cooling tower performance is defined as the
maximum flow rating of the tower divided by the fan
nameplate rated motor power''. Just to confirm, the
maximum flow rating refers to the water flow rate or to
the air flow rate of the fan? <o:p></o:p></span></p>

I've often worked with central systems that use chillers.
But for some project I see, there are condensing units and
evaporative units. My question is what table do these
equipment fit better: 6.8.1A, 6.8.1B or 6.8.1D? Please see
attached to look at the diagrams.<o:p></o:p></span></p>
