Course details

FAHU (Fresh Air Handling Unit) design involves the planning and sizing of HVAC systems that supply 100% fresh, conditioned air to buildings. It is commonly used in commercial buildings, hospitals, clean rooms, and industrial facilities where ventilation and indoor air quality are critical.

An FAHU is a type of Air Handling Unit that conditions outside air (cooling, heating, filtering, dehumidifying) before supplying it into indoor spaces, without recirculating return air.

FAHU design is a critical part of HVAC engineering, ensuring proper ventilation, thermal comfort, and air quality. A well-designed FAHU system enhances occupant health, meets regulatory standards, and improves overall building performance.

Questions and Answers

A: The 35C ambient is the breakpoint. At that condition, latent capacity margin is thin, so increasing coil control authority is the move that actually restores sensible capacity without pushing the coil into a wetter operating line that spikes RH.

A: The upstream location is the trigger. That geometry lets return air bypass the mixing section, so economiser logic can't maintain a stable mixed air condition no matter how good the controls are.

A: The 95 kW over 8.5 m3/s sets the answer. Using 1.2 kg/m3 and 1.02 kJ/kg·K lands you just under a 10.5 K drop, which puts leaving air near 19.5C.

A: The RH rise shows you're at the coil knee. A small SAT trim increases latent pickup without a big energy hit, whereas the other moves either add moisture or remove your only humidity control lever.
