Overall cooling and energy performance in a data center is crucial. Without the proper temperature, systems can overheat and fail, causing major disruptions and the possibility of losing data.
Energy Efficient Technologies installed hundreds of sensors in numerous data centers since 2008 to identify how this industry uses electricity over several years.
Based on this work, our engineering team identified a known issue in every oil lubricated HVAC, computer room air conditioner, chiller and refrigeration system.
This issue causes all of these machines to lose capacity and work harder due to the fouling of heat exchange surfaces – as much as 30% over time.
Energy conservation measures (ECM) were the focus of this project because their function restores the capacity of cooling systems and reduces energy use and carbon footprint.
Restoring the systems to full operating standards would:
CryoGenX4, the latest multi-patented nanotechnology offered by Energy Efficient Technologies, was introduced into the system and required no downtime for installation. The technology is composed of highly conductive, polarized electro-magnetic molecules that act quickly to forever displace the insulating layer of non-conductive material inside any HVAC/R system (commonly referred to as oil fouling). This does not change the characteristics of the oil or refrigerant in any system, it’s simply a surface science.
These polarized nano-technology molecules prevent refrigerant oil buildup from ever reoccurring. The result is a metal surface free of efficiency and capacity-robbing stagnant oil. That same oil-free surface is then enhanced with improved heat transfer properties. In addition, CryoGenX4 delivers better lubricity, allowing compressors to run at cooler temperatures by re- circulating refrigerant at a colder rate.
By reducing the negative effects of extreme heat, the HVAC and refrigeration system life is also extended.
When initially tested, the three pilot CRAC units were producing 24.26 tons of cooling. Seventeen days after implementing the ECM, the cooling capacity jumped by 3.94 tons or 16.2% to 28.2 tons.
After completion of this successful pilot, Cogent Communications is deploying CryoGenX4 in additional data centers with similar results- on average 20% reductions in energy use and carbon footprint.
“Energy Efficient Technologies deployed CryoGenX4 in five Cogent Data Centers. There was no downtime required in our critical cooling systems, we saw the savings in the electric bills and did not require any additional maintenance afterwards. I highly recommend CryoGenX4!”
