Title:
FLOW RATE MEASURING SYSTEM FOR COOL AIR FROM POROUS OPENING TYPE DOUBLE FLOOR PANELS
Document Type and Number:
Japanese Patent JP2016042233
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To make it possible to measure relative flow rate levels, which differ with the positional relation to an air conditioner, of the cool air blown up from porous opening type double floor panels by measuring the flow rate level of each panel only once.SOLUTION: A system for measuring the flow rates of cool air for ICT equipment in an ICT equipment operating room is equipped with a double floor under which cool air from an air conditioner flows and on whose top face the ICT equipment is arranged, opening panels that are installed beside where the ICT equipment is arranged on the double floor and constitute part of the double floor and into which multiple small holes for supplying cool air flowing underneath the double floor to the ICT equipment in the ICT equipment operating room flows are bored, a fluid sucking nozzle that is arranged over the opening panels and rectifies cool air from the holes in the opening panels and whose inflow port is in a trumpet shape having a diameter expanding toward the opening panels, the inflow port being provided with a fluid sucking nozzle covering all the multiple holes in the opening panels from above, and an anemometer that is arranged over an outflow port of the fluid sucking nozzle and measures the flow rate of cool air from the fluid sucking nozzle.SELECTED DRAWING: Figure 6
