Abstract
For energy efficient operation, uniform air temperature within the guidelines specified by the American Society of Heating Refrigeration and Air-Conditioning (ASHRAE TC 9.9 2011) at the rack inlet is desired. However, due to mixing with the hot room air, higher temperatures as compared to the supplied air temperature from the floor tiles can be present at the rack inlet, thus lowering the cooling effectiveness (Arghode et al. 2015b). In a raised floor data center, cooling air is supplied from an underfloor pressurized plenum through perforated tiles. Perforated floor tiles can have different geometrical features such as size, porosity, pore size and shape, blocked region at edges where perforations are absent, and anterior structures such as flow guiding fins or dampers for air flow control that can affect the air flow delivery to the adjacent rack, and hence the thermal field uniformity.
