The Best Of Adiabatic Data Center Cooling Solutions

- Feb 05, 2018-

Today, the volume of electronic data that businesses need to compute and store grows exponentially. The new physical data center space available increased, it has been difficult to meet the growth of market demand. Therefore, the challenge for people is to provide more computing capacity and power capacity in the same space. Requiring a higher level of computational processing power in the same physical space increases heat density, so data center owners need more efficient cooling systems solutions to meet market needs while meeting business growth.

One of the cooling technologies that is of concern to the industry today is adiabatic cooling, which consumes 90% less water than other refrigeration systems.


Balance the environment and bottom line

With the rapid development of the Internet, the demand for higher computing power of enterprises has increased year by year. However, the more powerful the IT system is, the more heat is generated. As data centers evolve, the demand for cooling equipment is also growing. Deploying thousands of kilowatts of computer resources in a smaller space is the key to reducing equipment costs and size. In doing so, the data center will increase the power density of the IT system, while increasing the power, the heat per unit area will be increased accordingly.

In addition to increasing power costs, data center owners and operators are also more concerned about the environmental impacts, including carbon emissions and their impact on local power plants and water usage. Although electricity costs and water supply may vary by region, data center owners around the world are concerned with reducing operational expenditures and by finding ways to transfer and process data more efficiently and with less than 10 years of electricity and water consumption s level.

To ensure that these powerful IT systems are in their best condition and will not interfere with normal operation due to overheating, their cooling systems must also adapt and grow. In order to maintain business profitability, data centers must balance advanced performance, strong technical advantages, and the cost of running such a computing system. Industry players have come to understand that the data center industry can no longer last as long as decades and that as the demand grows, larger data centers will continue to be established. The heat of the equipment room must be effectively removed without significantly increasing the cost of operating the data center.

Highly efficient adiabatic cooling

All cooling equipment must exclude heat from the air and most designers use evaporation or air cooling. Evaporative coolers (cooling towers) are more energy efficient than air-cooled systems, but they use large volumes of water and require costly manual maintenance and chemical treatment. Data centers can easily consume millions of gallons of water each year.

Air-cooled equipment works well when the ambient temperature is low, but consumes more energy during the hot season. This higher energy demand requires a larger and more expensive infrastructure to back it up. For example, the size of the backup generator must be as large as possible, so the size of the backup generator is much larger than the evaporation system.

Recently, new technologies emerged that provide the data center with a third cooling solution, adiabatic cooling, that combines evaporation and air cooling into a single system. The adiabatic cooling system uses the water evaporation effect to pre-cool the wet air around the ambient air, making the cooler more efficient and operationally more efficient.

Unlike conventional cooling towers, which use cooling water continually, adiabatic cooling systems use evaporative cooling only in the hottest part of the day. Air cooling will only reduce efficiency at unusually high ambient temperatures, so this is the only time that really needs evaporative cooling. For the rest of the year, the adiabatic cooling system meets the cooling load requirements of the plant without using any water, just as a simple air cooling system.

In most climates, adiabatic cooling systems use 90% less water per year than other systems. When the ambient air is high, you need evaporative cooling, the adiabatic cooling system to switch to effectively handle the annual cooling needs. When ambient air is reduced, evaporative cooling is no longer required and the adiabatic system can be switched to dry air without water for cooling. An adiabatic cooling system set up in this manner allows the data center to efficiently cool IT equipment using much less water than conventional cooling systems.

Because the evaporation process is confined within the insulation, the heat transfer coil can be kept completely dry, preventing unnecessary fouling and reducing reliance on costly chemical treatment systems.

Best of both worlds

Adiabatic systems consume far less electricity than air-cooled systems. These less powerful systems reduce the size of backup generators that support the cooling system. This reduces the cost of infrastructure and reduces the cost of building facilities while also reducing electricity and water bills. In addition, it saves data center space and can be used to deploy IT equipment in the data center when it is needed.

Adiabatic technology has been used for air treatment on the air side of the data center industry for many years but can only be used in machinery and equipment and the packaging units manufactured at the factory are ready for immediate use. The technology can be applied to fluid cooler, condenser, condensing unit, chiller.

In order to reduce the workload, the data center is seeking innovative ways to reduce operating costs as much as possible, and the updating and upgrading of computer technology are rapidly changing. To meet the needs of users who deploy more dense and powerful IT equipment, data center technologies also urgently need cooling technology that can keep up with the times. New products for machinery and equipment, including packaged adiabatic cooling technology, help data center owners and operators address the growing challenges of power costs and environmental issues.
