氣冷式熱交換系統優點簡介

 Air Cooled Heat Exchangers are normally used where a process system generates heat which must be removed, for which there is no local use.

They are a “green” solution as compared to cooling towers and shell and tube heat exchangers because they do not require an auxiliary water supply (water lost due to drift and evaporation, plus no water treatment chemicals are required). Where there is a no utility such as water available as a cooling medium

They are usually used when the outlet temperature is more than about 20 deg. F above the maximum expected ambient air temperature. They can be used with closer approach temperatures, but often become expensive compared to a combination of a cooling tower and a water-cooled exchanger. Fig. 1 shows the operating principle of a typical Air Cooled Heat exchanger.
