Increased efficiency is achieved through the use of raised floor panels with variable openings from Sandra Brown's blog

Low operating costs, high flexibility, and redundancy are all requirements that can be met with a proven system for data center air conditioning that utilizes convection cooling via raised floors.
However, in the vast majority of cases, the air escaping from the raised floor is still uncontrollable. Raised floor panels controlled by sensors and capable of opening to a variable degree are an important component in this design in order to reduce the energy consumption of the air conditioning system.

A raised floor manufacturer will typically also provide the perforated panels for the air outlet, which is a convenient option. In most cases, the customer has the option of selecting from a variety of perforation levels. Some manufacturers also offer throttle plates that are mounted on the underside of the plate, allowing the user to manually control the amount of air that is drawn through the plate.
The amount of air that is actually required is determined by the amount of load placed on the server. Load fluctuations are common in the modern era of server virtualization and cloud computing, in particular, because entire racks are turned on and off at the same time. Flexible solutions for recirculating air conditioning are also required in order to accommodate the fluctuating load behavior of the server. The challenge is to provide enough and specifically cooled air to the servers to keep them running smoothly. It should be sufficient when the exact amount of air required by the servers is allowed to exit the raised floor. Targeted air exiting the raised floor means that the air exits the raised floor as directly as possible in front of the server rack's air inlet. Last but not least, this applies in situations where cold and warm corridors are not physically separated from one another by structural measures. It is less likely that cold and warm air will mix when cold air is delivered on demand directly in front of the server intake. As a result, it is possible to speak of a virtual containment system.
When it comes to the access floor panels, Huiya provides a versatile solution that, with its dimensions of 600 x 600 mm, can be integrated into the grid of commercially available raised floor panels. The degree to which the flaps open can be controlled by the building management system (BMS) or directly by the airflow system's own controller, which can be controlled by temperature or pressure differences, depending on the situation. The flaps are automatically opened by a return spring in the event that the power supply is interrupted. Due to the fact that the entire unit is terminated with a flow-optimized grating, it is also protected from mechanical loads such as those caused by lifting vehicles.
AccessFloorStore. Com is a China-based company that specializes in the manufacturing of raised floors and vinyl floors. Established in 2005, the company has grown and now is the only one in China capable of providing all of the raised access floor types currently in demand on the market: panels of wood chipboard or steel raised access floor tiles are introduced both in the traditional version with a bordering side and in the new generation of steel encapsulated panels.
Productivity improvements through innovative production lines and international design, as well as meticulous pre and post sales service, ensure high quality and total dependability of the product. All of these characteristics allow the Huiya raised floor to meet the stringent quality requirements stipulated by the ISO 9001:2008 certification.
Huiya raised access floor tiles are high-quality products that are made from environmentally friendly wood chipboard or calcium sulphate cores, respectively. In addition to the traditional version with bordering sides, the Huiya raised floor is also available in a new generation of steel encapsulated versions.
The raised floor structure of the Huiya building is entirely constructed of steel with a zinc surface coating. The pedestals are made up of two distinct elements known as the base and the head, which are eventually joined together by stringers, depending on the height of the finished floors and the performance load that is required of them.
The top side of the Huiya access floor can be finished with a variety of different raised access floor coverings; every technical and aesthetic requirement can be met in any environment, and there are no restrictions on the types of finishes that can be applied to the panels.
It is equipped with all of the accessories required to solve any installation or plant engineering problem, such as air distribution accessories, electrical and data outlet boxes, access steps, ramps, vertical closing sector (for vertical closing), acoustic pads, and so on. Huiya raised floor systems are available in a variety of sizes to suit any application.
