Data Center Perforated Tiles for Cooling ServersThere is a lot to consider with perforated tiles in data centers and depending on who you talk to you will get different answers. The server floor in a data center is typically built on a raised floor with cold air being pumped under the floor by large CRAH(Computer Room Air Handlers) or CRAC units (Computer Room Air Conditioners). This cold air is flows through the perf tiles and into the data center to cool the load of the heat the servers and other ancillary data center electrical equipment produce. The data center load is a sensible load as data centers do not have a lot of humidity in them from outside sources so the cooling equipment need only be capable of cooling the sensible load with little worry about any latent loads.
