Perforated Air Floor Raised Floor Panels For Data Centers

With the Air Flow Raised Floor Panels, Huiya offers a versatile solution that, with its dimensions of 600 mm x 600 mm, fits into the grid of commercially available raised floors. The degree of opening of the flaps can be regulated as required via the building management system (BMS) or directly from the airflow system own controller via the temperature or pressure differences. If the power supply is interrupted, the flaps are automatically opened by a return spring. The entire unit ends with a flow-optimized grating and is therefore also protected from mechanical loads, for example from lifting vehicles.
In most cases, the raised floor manufacturer also supplies the perforated panels for the air outlet. The customer can usually choose between various degrees of perforation. Some manufacturers also offer throttle plates that are mounted on the underside of the plate and thus enable manual control of the air volume.
The amount of air actually required depends on the load on the server. In the age of server virtualization and cloud technologies in particular, load fluctuations occur because entire racks are switched on and off. In line with the fluctuating load behavior of the server, flexible solutions are also required for recirculating air conditioning. The challenge is to provide the servers with sufficient and specifically cooled air. Sufficient should mean that the exact amount of air that is currently required by the servers leaves the raised floor. Targeted means that the air exits the raised floor as directly as possible in front of the server rack's air intake. The latter applies in particular where cold and warm corridors are not separated from each other by structural measures. The need-based supply of cold air directly in front of the server intake reduces the mixing of cold and warm air. One can therefore also speak of a virtual containment.
