Atmospheric air, which is a mixture of dry air and water vapour, is supplied into ducting with a cooling coil. Initially it has a relative humidity of 0.57, volumetric flow rate of 0.72 mis and temperature of 17°C. The atmospheric air is then passed over a cooling coil such that the temperature drops to 6°C. As this is below the dew point, the water vapour condensates after cooling coll and the air leaves in a saturated state.
