Figure 10.1 Condensation in charge air coolers
Example, according to the diagram:
At an ambient air temperature of 35°C and a relative humidity
of 80%, the content of water in the air is 0.029 kg water/ kg dry
air. If the air manifold pressure (receiver pressure) under these
conditions is 2.5 bar (= 3.5 bar absolute), the dew point will be
55°C. If the air temperature in the air manifold is only 45°C, the
air can only contain 0.018 kg/kg. The difference, 0.011 kg/kg
(0.029 - 0.018) will appear as condensed water.
