Cooling is a significant cost of any data center with Servers, PCs and other electronic equipment that need cooling. Heat is known to be responsible for 55% to 60% of the hardware failures in a data center. Other causes are humidity, dust and vibration. Cooling and managing air flow can therefore improve the lifespan of the hardware in the data center, but this can also create a new expense that the organization will have to deal with. Managing Cooling Costs It is therefore important to come up with a solution that can manage the initial costs, as well as the recurring energy costs. Access computer floors can help to reduce these costs if they are used correctly to provide an efficient cooling system for the server rooms and other parts of the data center. This type of raised flooring utilizes the under floor air to cool servers and other areas in the office space. The cool air underneath is directed with minimal use of fans and the computer room air conditioner. Cool air is directed upwards from the space underneath and it naturally pushes the lighter warm air away. Elaborate Cooling System For a data center with a high cooling load, the system is a little bit more complicated. The air flow underneath the raised flooring is directed upwards by cables strategically placed near holes on the panels. The holes may be simply made to allow cables to find their way back to the server room and play another role of regulating the amount of cool air that moves upwards. There are several advantages of this system of cooling. The first is the Air conditioning of the room requires little energy from the fans and coolers since cool air moves naturally upwards displacing the existing warm air. This also has another desirable effect of pushing out dust which would otherwise be pushed into the room by ceiling fans. Dust which also causes hardware failures gets less chance of getting into the room. Saving Energy Costs The concrete slab cools the air trapped between the slab and the panel. Concrete is always cooler than the rest of the room, this coolness can be utilized instead of using coolers. The advantage if this is that the cool air is directed to precisely where it is needed. The raised floor reduces both the initial costs and the recurring energy costs. The initial costs are minimized because the design of the building requires less space between the bottom and upper slabs. The energy costs are reduced by a very efficient cooling system.
