Specification Value

■Where a fluid cooler is installed in a building well or there are high surrounding walls, it is possible that a proportion of the hot and humid discharge air will be drawn back into the fans thus increasing the inlet wet bulb temperature with detriment to the fluid cooler per- formance.

The tapered discharge duct is intended to increase the exit velocity by up to 70% in order to reduce the effects of recirculation in some installations. Experience and sound judgement should be exercised to determine when and if a duct is required.

If the surrounding walls are much higher than the fluid cooler dis- charge height, then extensions to the tapered duct may be installed.
