Sizing Instructions Follow these steps to properly size the Industrial MasterCool. The performance or Sensible Heat Capacity of any cooler is a function of both the CFM and saturation effi ciency (which determines the delivered air discharge temperature). Sizing by only considering CFM may result in an improperly sized application. 1. Determine design conditions: Outdoor Dry-Bulb DB1 Outdoor Wet-Bulb WB1 Indoor Dry-Bulb T1 2. Determine design sensible heat load (Btuh) 3. Determine leaving air temperature (LAT): LAT = DB1 - [(DB1 - WB ) * EFF] where EFF ‘ 0.80 for 8” media or 0.90 for 12” media 4. Determine CFM required: CFM = 0....
