Air cooled heat exchangers design good practices for temperature selection, Air re-circulation, Leaks, Approach temperature, Mean-temperature-difference (MTD) correction factor, Maintenance Cost, and Operating Costs. The dry-bulb temperature that is selected should be more than 2.5 percent of the warmest ambient temperatures with an addition of 5.4 ०F (3 ०C) as a contingency. Air recirculation: Prevailing winds and the locations and elevations of buildings, equipment, fired heaters, etc., require consideration. All air-cooled heat exchangers in a bank are of one type, i.e., all forced-draft or all induced-draft. Banks of air-cooled exchangers must be placed far enough apart to minimize air recirculation. During winter or extreme weather conditions, shelter needs to be considered for heavy rain, strong winds, freezing of moisture upon the fins, etc. More the number of fans, more the noise pollution. To reduce this noise pollution exchanger position, the reflective surfaces near the fan,
