supplying fresh air at required temperature space that is tfa
air handling units reserculate the treated air at required temperature at any serving area but fresh air unit did not reserculate fresh air , exhaust used air.
The difference between an air handling unit and a package unit have to do with the way air is circulated or cooled. An air handling unit recycles the air from the structure back into the system. A package unit cools the air as it enters a structure through the use of intake fans.
Fresh air units, or air handling units, are designed to condition and circulate fresh outdoor air into indoor spaces. They typically consist of components such as fans, filters, heating/cooling coils, and dampers. The unit draws in outside air, filters it to remove contaminants, and then heats or cools it to the desired temperature before distributing it throughout the building. This process enhances indoor air quality and maintains comfortable environmental conditions.

FAHU = Fresh Air Handling Unit. It sucks fresh air from surroundings and filters the air in two stages to remove dust pollen etc and supplies the fresh air inside the sealed building. this air will be have a temperature between 22-25oC.
The operating principle of air handling unit is by circulating and then conditioning air flow. This is achieved by cooling, heating and ventilating the units.
Yes. The blower motor of an air handling unit can be considered as an ignition source.

to prevent the unit from freezing. Glycol is a an antifreeze agent
SA stands for supply air. Air is delivered to your space from a sort of air handling unit(fan). This is the conditioned air whether heat or cooling. This air would be returned to the air handling unit to be reconditoned through the return air(RA) duct .
