While there are advantages to the OHAD system, the obtained CFD findings demonstrated that the UFAD system may outperform it.
The computational fluid dynamics (CFD) findings validated that, in comparison to the OHAD system's 1.2 m height, the UFAD system could keep the room temperature at 26°C while being located below 2.0 m.
