Air cooler heat exchanger design.
Air cooled heat exchanger.
One or more bundles of the heat transfer surface.
An air cooled exchanger is used to cool fluids with ambient air.
They are widely used in space heating refrigeration air conditioning power stations chemical plants petrochemical plants petroleum refineries natural.
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 heat capacity of gases is essential for some process engineering design e g for air cooled heat exchanger and for gas phase chemical reactions.
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.
Process design of air cooled heat exchangers air coolers project standards and specifications page 4 of 19 rev.
1 inch od tube 5 8 inch fin height 10 fins per inch and 2 5 inch triangular pitch.
Of 180f to less than 10 f above ambient of 105f 650 to 1 000 psig operating pressure.
Aches for process plants are normally just called aircoolers but should not be confused with devices for cooling air best described as air chillers.
The design of an ache is more complex than for a shell and tube heat exchanger as there are many more components and variables.
Tube configuration used in this guideline.
15 mm scfd of wet natural gas sp.
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.
The obvious advantage of an ache is that it does not require water which means that plants requiring large.
2nd bundle 1 200 bpsd of condensate sp.
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.
A mechanical driver and power transmission for running the fan or blower.
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.
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.
