Appendix H: Modeling UFAD and DV in ApacheHVAC
Web1 Aug 2010 · In terms of room air stratification, UFAD systems represent an intermediate condition between a well-mixed zone and DV. Since, air is supplied through an underfloor plenum at low pressure through diffusers in a raised floor. These produce less mixing in the zone which will allow for stratification.
