Fresh air containing 4.00 mole% water vapor is to be cooled and dehumidified to a water content of 1.70 mole% H2O. A stream of fresh air is combined with a recycle stream of previously dehumidified air and passed through the cooler. The blended stream entering the cooler contains 2.30 mole% H2O. In the air conditioner, some of the water in the stream is condensed and removed as liquid. A fraction of the dehumidified air is recycle and the remainder is delivered to the room. Taking 100 mol of dehumidified air delivered to the room as a basis of calculation, calculate the moles of fresh feed, moles of water condensed, and moles of dehumidified air recycled.
