| | DECEMBER 20209With the advancement and adoption of technology in almost everything in today's world, there is no area left in our daily lives that aren't influenced by it, and it's no wrong to say that we are spending almost more than half of our day in the online world. Today, internet is considered as everyday necessity. From workplaces to general uses, internet has become the fuel for engines, and with almost everybody owning smartphones, most of our waking moments are spent connected online. And this is all possible because of the existence of data centers.Naturally, the demand for real-time data transmission is an all-time high. This need for computers and other networking equipment which handles these requests is the catalyst for the immersion of the data centers. Data centers are where computing facilities and networking equipment are located and centralized. They are tasked to collect, store, process, and distribute large amounts of data. Data centers have also been around since the dawn of the modern computing age. An average data center demands a huge amount of electricity, and that is obvious considering the amount of computing power they manage to fit onto a single data floor. Not to mention an imperative factor - the cooling infrastructure that data centers demand to maintain the ideal operating environment for all that equipment. Taken together, data centers consume about three percent of the world's electricity.The sole purpose of data center cooling technology is to maintain environmental conditions suitable for information technology equipment (ITE) operation. Achieving this goal requires removing the heat produced by the ITE and transferring that heat to some heat sink. In most data centers, the operators expect the cooling system to operate continuously and reliably. These factors have led the data center cooling industry to surge and become a prominent in the IT space. The global data center cooling market size was valued at $8.6 billion in 2018 and is expected to grow at a compound annual growth rate (CAGR) of 13.5 percent from 2019 to 2025.The increasing need for energy-efficient data center facilities, growing investments by managed service and colocation service providers, and increasing construction of hyper scale data centers are some factors, that are expected to drive the market in the coming future. Having proper temperature management in data center is absolutely vital to maintain the functionality of the equipment. Having an excess of warm air and humidity within a data center can create a financial burden for a business that can be avoided.Process of Cooling Data CentersTraditional data center cooling techniques used a combination of raised floors and computer room air conditioner (CRAC) or computer room air handler (CRAH) infrastructure. The CRAC/CRAH units would pressurize the space below the raised floor and push cold air through the perforated tiles and into the server intakes. Once the cold air passed over the server's components and vented out as hot exhaust, that air would be returned to the CRAC/CRAH for cooling. Most data centers would set the CRAC/CRAH unit's return temperature as the main control point for the entire data floor environment.Some Other Techniques Used For Data Center Cooling Are As Follows:Free Cooling - Cooling costs can account for more than half of a data center's total annualized operat-ing cost as energy costs and IT power consumption continue to rise. Free cooling being the most cost-ef-fective way of data center cooling, ensures perfect-FREE COOLING BEING THE MOST COST-EFFECTIVE WAY OF DATA CENTER COOLING, ENSURES PERFECTLY THAT A DATA CENTER'S TEMPERATURE FLOW IS PROPERLY FUNCTIONING
