Air Cooler Heat Exchanger Design

One or more bundles of the heat transfer surface.

Air cooler heat exchanger design.

They are widely used in space heating refrigeration air conditioning power stations chemical plants petrochemical plants petroleum refineries natural. Aches for process plants are normally just called aircoolers but should not be confused with devices for cooling air best described as air chillers. 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. An air cooled heat exchanger consists of the following primary components refer to fig.

A fan or blower which moves the air. 1 inch od tube is the most popular diameter and the most common fins are 1 2 inch or 5 8 inch high. 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 mechanical driver and power transmission for running the fan or blower.

Of 180f to less than 10 f above ambient of 105f 650 to 1 000 psig operating pressure. 1 inch od tube 5 8 inch fin height 10 fins per inch and 2 5 inch triangular pitch. Components of an air cooled heat exchanger. The design of an ache is more complex than for a shell and tube heat exchanger as there are many more components and variables.

The obvious advantage of an ache is that it does not require water which means that plants requiring large. 01 april 2011 3. 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. Air cooled heat exchanger design achex software is made to demonstrates the thermal design and sizing calculations of air cooled heat exchangers.

2nd bundle 1 200 bpsd of condensate sp. Gr 0 63 with less than 2 co2 at an inlet temp. 15 mm scfd of wet natural gas sp. Air cooled heat exchanger.

The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. Process design of air cooled heat exchangers air coolers project standards and specifications page 4 of 19 rev. An air cooled exchanger is used to cool fluids with ambient air. 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.
