Consider an air conditioner operating in a recycle system mode where fresh air taken trom the amblent atmosphere is to pe cooied and Cehumicified and then detvered to a room. Fresh air taken from the ambient atmosphere contains 5 mons water This fresh air steam is then mixed with the recyci stream and the resulting stream contains 2.5 mols water, This stream coming out of the moer is led into the air conditioner unt. Where a fraction of water present in the air is conoensed and removed as iquid, the other streaim containing 1.7 molts water is taken cut ane 15 ted into a spinter where one stream is taken as the recycle stream and other stream is deivered into the room. The air which is dellverad fo the room contains 1.7 mols water. Present the following assuming 500 molesminute of ai (containing 1.7 mons water) is detivered to the room [3+4+6=13maks) Wrawr a lasesed nownneet W.
