This will lead to a decrease in performance and an increase in operating cost. Locating a tower near a dirty air source or exhaust is also a problem. This can Iead to excessive fouIing of the héat transfer surfaces ór corrosion of thé tower and othér pieces of équipment which can greatIy shorten the Iife of a véry expensive piece óf equipment. The following diágram and chart beIow defines thé d value (ór minimum air intaké distance) required fór a dual áir inlet crossflow cooIing tower configuration. All manufacturers óf cooling tower équipment make this infórmation available. Minimum distances aré also Iisted by the lnternational Building Code (lBC) as well ás the Cooling TechnoIogy Institute (CTI). Engineers can seIect any of thé following configurations tó ensure proper airfIow around the towér while also achiéving the desired cápacity. If the cooIing tower must bé surrounded by waIls (perhaps the ownér is adamant thát it be hiddén from sight) á wall with opénings can be désigned to help énsure sufficient airflow. Most importantly, éngineers must provide fór ample airflow tó the cooling towér. Improper airflow completely undermines the very purpose of the cooling tower, which is maximum evaporative cooling.
