Differences between air handling unit and fan coil unit
In a sense, air handling units are installed for the purpose of cooling/heating the entire building, but fan coils are used for cooling/heating individual rooms. Fan coil units also require a heat source medium.
Generally, heated/chilled water serves as a heat medium for fan coil units (FCU). Water heated or chilled from another location is sent to the fan coil unit for use in providing warm/cool air to the rooms.
Fan coil unit also come with accessories as option based on the design. Some fan coil units are provided with heater banks before or after the cooling coil based on the purpose of sensible heating or de humidification purpose.
Some designs demands for UV in front of the coil at discharge side to eliminate pathogens especially where the air is been served to sensitive areas like laboratory, hospitals rooms etc.
Differences between air handling unit and Fresh air handling unit
A Fresh Air Handling Unit (FAHU) is a type of AHU that is specifically designed to bring in and condition fresh outside air. It is typically used in buildings where there is a high demand for fresh air, such as hospitals, laboratories, or other commercial / residential buildings where indoor air quality is of utmost importance.
Unlike a regular AHU, a FAHU does not recirculate air within the building. Instead, it pulls in fresh outside air, filters it, and then conditions it before distributing it to various parts of the building. There are several options of energy saving with heat recovery wheel and de humidification and RH factor maintenance by heat pipe.
In summary, the main difference between an AHU and a FAHU is the source of the air they handle. While an AHU can handle both fresh outside air and recirculated air from within the building, a FAHU is specifically designed to handle only fresh outside air.
