Purpose Of Intercooler And Aftercooler in An Air Compressor

An intercooler is a device that cools the air that has been compressed by the turbocharger before it enters the engine combustion chamber. The compressed air is warmed up by the compression process, which reduces its density and oxygen content. The intercooler cools the compressed air before it enters the engine intake manifold, thereby increasing its density and oxygen content, resulting in a more efficient combustion process and increased power output.

On the other hand, the aftercooler is used to cool the compressed air exiting the engine's combustion chamber. The hot exhaust gases pass through the turbine of the turbocharger, which drives the compressor to compress the air. Once compressed, the hot compressed air passes through the intercooler to remove the heat generated during the compression process, thickening the air and increasing its oxygen content before it enters the engine intake manifold.

In short, the intercooler cools the compressed air before it enters the engine combustion chamber, while the aftercooler cools the compressed air after it exits the engine combustion chamber. Both devices increase the efficiency of the engine by increasing the density and oxygen content of the air, thus improving combustion and increasing power output.
