Air Cooler Heat Exchanger Design

Furnaces should be considered when choosing the location of the air cooled heat exchanger and selecting the design temperature.

Air cooler heat exchanger design.

The proximity of potential sources of warm air e g. The annual power requirement for an exchanger is a function of the means of air flow control the exchanger service the air temperature rise and the approach temperature. Where for reasons of control an air cooled heat exchanger has to be provided with automatic variable pitch fans as in the case of overhead condensers it shall not share its fans with air cooled heat exchangers on other duties for example product run down coolers. When using a combination of air and water cooling it is usually best to design the air cooled heat exchanger for a somewhat lower ambient temperature than what would be used if there were no trim cooling and then to design the trim cooler for the process fluid temperature which would be discharged by the air cooled heat exchanger at the higher ambient temperature.

An air cooled heat exchanger consists of the following primary components refer to fig. Components of an air cooled heat exchanger. A fan or blower which moves the air. Download air cooled heat exchanger design for windows to perform thermal design calculations and sizing of air cooled heat exchangers.

Air cooled heat exchanger design has had 1 update within the. Kays london s compact heat exchangers 1 contains measured heat transfer and pressure drop data on a variety of circular and rectangular passages including circular tubes tube banks straight fins louvered fins strip or lanced offset fins wavy fins and pin fins. It is concerned with such matters as choice of exchanger specification of duty. Power requirements for air cooled heat exchangers can be lower than at the summer design condition provided that an adequate means of air flow control is used.

A mechanical driver and power transmission for running the fan or blower. One or more bundles of the heat transfer surface. As a guide the in plant temperature may be 2 3 c over the local ambient temperature.
