The proliferation of data brings the energy efficiency of data centers to the forefront in an effort to lower investment and operating costs, as well as their impact on the environment. Deerns Consulting Engineers has developed a three step approach to reducing the energy used to cool data centers by 80 percent while maintaining the reliability of the cooling system. The reduced system infrastructure and modularity also results in lower investment costs and increases the phasing of investment.
Step one focuses on total cost of ownership. The company uses free cooling which has resulted in up to 25 percent less cooling energy consumption in certain data centers. In Deerns model, outdoor air is drawn through a plate heat exchanger, where it absorbs heat from the IT room’s hot return air. Next it’s cooled and re-circulated through the data center. By separating the air streams, the outside air can be cooled evaporatively without influencing the humidity in the CONTINUE READING ARTICLE ON WIREDRE GROUP BLOG
