Air cooler heat exchanger design.

A heat exchanger is a system used to transfer heat between two or more fluids heat exchangers are used in both cooling and heating processes. Tube configuration used in this guideline. 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. 01 april 2011 3.

An air cooled heat exchanger consists of the following primary components refer to fig. Of 180f to less than 10 f above ambient of 105f 650 to 1 000 psig operating pressure. A mechanical driver and power transmission for running the fan or blower. One or more bundles of the heat transfer surface.

The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. The obvious advantage of an ache is that it does not require water which means that plants requiring large. 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 fan or blower which moves the air.

They are widely used in space heating refrigeration air conditioning power stations chemical plants petrochemical plants petroleum refineries natural. An air cooled exchanger is used to cool fluids with ambient air. 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. Aches for process plants are normally just called aircoolers but should not be confused with devices for cooling air best described as air chillers.

Process design of air cooled heat exchangers air coolers project standards and specifications page 4 of 19 rev. The design of an ache is more complex than for a shell and tube heat exchanger as there are many more components and variables. 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. Components of an air cooled heat exchanger.

Air cooled heat exchanger. 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. 1 inch od tube is the most popular diameter and the most common fins are 1 2 inch or 5 8 inch high. Gr 0 63 with less than 2 co2 at an inlet temp.
