thanks Alec…now i understand…
Air Handling Units are basically referred to as a generic term for anything or any device which is involved in the transportation, heating or cooling of air. After the heating or cooling of the air the air stream is moved forward or directed to the required placed through air ducts which includes rooftop units and furnaces.

The fan coil units are smaller and self contained than the AHU’s. And the major difference between AHU and FCU lies in the fact that in FCU’s there is no ducting involved for the movement of air. In the FCU’s the fan in the internal section of the FCU carries out the function of moving the air over a heated or cooled coil and then directly moving out the air into the surrounding air without the use of any ducts.
The FCU’s can also be used in the case of water also where as AHU’s deal with air only.
The working of an FCU is as follows. An FCU consists of a coil and a fan. It receives air from a central plant which is cooled or heated up by the
