Air Cooler Heat Exchanger Design

Components of an air cooled heat exchanger.

Air cooler heat exchanger design.

Gr 0 63 with less than 2 co2 at an inlet temp. Process design of air cooled heat exchangers air coolers project standards and specifications page 4 of 19 rev. An ache is a device for rejecting heat from a fluid directly to ambient air this is in contrast to rejecting heat to water and then rejecting it to air as with a shell and tube heat exchanger and a wet cooling tower system. Of 180f to less than 10 f above ambient of 105f 650 to 1 000 psig operating pressure.

The obvious advantage of an ache is that it does not require water which means that plants requiring large. The heat capacity of gases is essential for some process engineering design e g for air cooled heat exchanger and for gas phase chemical reactions. A fan or blower which moves the air. An air cooled exchanger is used to cool fluids with ambient air.

15 mm scfd of wet natural gas sp. Air cooled heat exchanger. An air cooled heat exchanger consists of the following primary components refer to fig. Here in the latter case the heat capacities c p 0 for gases are required to determine the heat necessary to bring the chemical compound increase to the reaction temperature.

Air heat exchanger manufacturer stefani combines typical italian creativity with a strong spirit of innovation which leads the company to propose ever more performing air cooler units blast chillers condensers and dry coolers for industrial and commercial refrigeration. The design of an ache is more complex than for a shell and tube heat exchanger as there are many more components and variables. Where expensive or insufficient water supplies are encountered or where cooling water pumping or treating costs are excessive it is often found that air cooled units are desirable for several services. The software will design horizontal induced draft or forced draft units for liquid and gas services and will produce a three page summary of all results and a basic drawing representation.

1 inch od tube 5 8 inch fin height 10 fins per inch and 2 5 inch triangular pitch. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. One or more bundles of the heat transfer surface. Aches for process plants are normally just called aircoolers but should not be confused with devices for cooling air best described as air chillers.

01 april 2011 3. Tube configuration used in this guideline. A mechanical driver and power transmission for running the fan or blower. 2nd bundle 1 200 bpsd of condensate sp.

Air cooled heat exchanger design achex software is made to demonstrates the thermal design and sizing calculations of air cooled heat exchangers.
