by Marissa Donatone on 10/6/15 9:27 AM

Designed to save millions of gallons of water and increase energy efficiency by up to 50 percent

liebert-dse-mediumColumbus, Ohio [September 16, 2015] – Emerson Network Power, a business of Emerson, (NYSE: EMR) and the world’s leading provider of critical infrastructure for information and communications technology systems, today announced that the California Energy Commission (CEC) has approved the use in California data centers of the Liebert® DSE thermal management system with the Liebert EconoPhase Pumped Refrigerant Economizer. The Liebert DSE system represents a break-through technology that uses no water and saves up to 50 percent of thermal energy, through its patented design and advancedLiebert iCOM™ controls.  

“The Liebert DSE system is a great environmental steward. When used in a typical mid-sized data center of one megawatt load, the Liebert DSE is significantly more efficient than current cooling systems, and eliminate the use of around four million gallons of water each year. If deployed broadly in California data centers, the Liebert DSE with EconoPhase could save hundreds of million gallons of water every year,” said John Peter Valiulis, vice president North America marketing, thermal management, Emerson Network Power.
 
The CEC has approved the Liebert DSE system with Liebert EconoPhase as a prescriptive economization option, as part of Title 24 of the the CEC’s 2103 Building Energy Efficiency Standards For Residential and Non Residential Buildings, meeting the code’s requirements for energy efficiency and its prescriptive requirements for economizers.
 
The Liebert DSE system eliminates the need for any water in the heat rejection process and associated chemical water treatment, and it eliminates the risk of exposure to harmful waterbound bacteria. In addition, the Emerson modeling for the CEC compliance program demonstrated an 8 to 10 percent reduction in the data center Time Dependent Valuation measure, compared to the water economizer prescriptive option. The Liebert DSE system design also reduces or eliminates several of the power components associated with water economizers. In actual usage, the entire Liebert DSE system has demonstrated thermal system energy savings of up to 50 percent over older legacy systems.

ECO-Friendly Choice in Single Phase UPS

by Miguel Rascon on 3/26/15 2:46 PM

ECOblog

“Environmental protection”, “high efficiency” and “energy savings” are topics of very high concern for both large corporations, as well as for individuals since these aspects are part of everyday life and may generate significant cost savings in both cases.

This is also valid for UPS ranging from large ones protecting substantially vast datacenters, to small ones with just a few kilowatts that safeguard a network or single cabinet in more modest settings.

The ECO mode – also known as energy saving mode or high efficiency mode depending on the UPS manufacturer – is currently highly discussed within the industry. The debate primarily focuses on on-line UPS and on large UPS. Nevertheless, energy savings and efficiency are extremely important aspects also in small and micro power UPS (typically from 500 VA to 10 kVA). The reasons are the same as for large power systems: savings on energy costs and lower environmental footprint.

Choosing a UPS in the most proper way, means considering the criticality of the application that needs to be protected, as well as evaluating the energy used by the UPS to protect the load against disturbances and interruptions.

Here I would like to highlight the “inherent ECO mode” that can be found in line interactive UPS products (VI or Voltage Independent according to EN 62040-3).

In this type of line interactive UPS (VI), the power stream flows from the input through several protection devices (overcurrent, overvoltage, etc.) and mainly through an Automatic Voltage Regulation (AVR) transformer.

The AVR is in charge of providing output voltage regulation, in order to minimize voltage variations in AC supply and ensure a regulated voltage according to the load tolerances.

Because of the high efficiency of the AVR (typically around 98% or 99%) and of the protection devices through which energy flows, as well as the lower quantity of electronic components used in this type of UPS topology, a high performance line interactive UPS can provide an efficiency level higher than 96% at full load. A perfect example of this is Liebert PSI UPS, which makes use of line interactive technology and therefore of AVR, and which can reach the efficiency levels mentioned above. As said, this operation mode is inherent to line interactive UPS topology, and its high efficiency is also ensured in wide load operating conditions and AC mains variation. While ECO mode in on-line UPS is operating in a smaller input voltage range, line interactive topology is able to operate in high efficiency mode during most input voltage changes while still being capable to provide some output regulation.

When comparing a line interactive UPS with a double conversion online UPS there are many aspects to be taken into consideration such as stepwise or pure sine wave inverter, transfer time, size, etc. However one of the main differences is exactly that line interactive UPS feature “inherent high efficiency” because of the VI technology and the use of AVR as mentioned earlier.

The energy savings associated to it are highly appreciated even if we are talking about single phase UPS meaning UPS which range from 0 to 10 kVA, because:

1. Daily saving  just  a  few  watts  in  continuous UPS operation 365 days a year amounts to a significant total yearly saving

2. In applications such as campuses or big corporations where many of these small UPS devices are used contemporarily, the few watts saved daily per each device increase even more the daily and yearly total saving and reduce the total campus or corporation expenditure.

To provide an example, assume a load of 2.5 kW being protected by a UPS. Such load may correspond to a cabinet with several servers for enterprise applications or to a wiring closet distribution panel. Such UPS can work in line interactive mode (assuming 97% efficiency) or operate in double conversion mode with 90% efficiency, using a rough estimation. The difference in power losses and thus energy savings, will be around 200 W. Assuming an electricity cost of 0.138 €/KWh and doing a quick calculation on yearly savings, you can get a value of around 272 € saved per year. This amount can be multiplied for five years and the total saving will reach nearly 1,500 €.

So it will be clear by now that additional to traditional ECO mode (typically used in double conversion online UPS in general and large UPS in particular) there is an inherent ECO mode used in single phase UPS, specifically line interactive ones.

This grants significant savings to customers as the line interactive technology is inherently highly efficient and as the UPS making use of it are typically used daily all year long so in the long term even little daily saving amounts to a considerable total figure.

And what about ECO modes in on-line UPS in this small UPS range? Is there any difference or advantage? There is an interesting story too.

How infrastructure monitoring can help increase data center efficiency and availability

During the first decade of the 21st century, the data center emerged as a significant corporate asset, playing a vital role in business management and customer service. Throughout this period, the data center underwent an evolution as computing and data storage capacities increased significantly.

Data centers have traditionally been designed with extra headroom to accommodate growth, but during the last decade, demand escalated so quickly that added IT capacity consumed available headroom and outpaced supply in terms of floor space and power and cooling capacity. This created conflicts as facility personnel struggled to supply IT’s demand for server capacity.

 

These problems were further worsened by two trends that emerged in the second half of the decade.

1. The first trend is the increased focus on data center energy consumption. With both the density and quantity of servers rising, data center energy consumption became a significant factor in terms of IT cost management and, in some companies, response to concerns about global warming. Early efforts to reduce data center energy consumption focused on lowering costs around data center cooling, which accounts for approximately 35 percent of data center energy consumption.

2. The second trend was the adoption of virtualization technologies. In a recent survey of data center managers, virtualization adoption rates stood at 81 percent. This has created a dynamically changing application environment layered on an essentially static physical environment, increasing data center complexity and introducing new challenges to physical infrastructure management.

In most organizations, data center managers lacked the tools to effectively address these challenges. The network management systems essential to IT personnel in monitoring and managing IT equipment did not address the critical issues of energy consumption, available rack capacity, or ambient air temperatures that are essential to proactive data center management. Further, the building management systems used by facility personnel to monitor power and cooling in the data center failed to provide the alarm management capabilities required for critical systems and to account for the interdependencies between systems. Evolving from a reactive to a proactive approach to infrastructure monitoring requires a new type of management system that provides visibility into the data center’s physical infrastructure within both the IT and facility domains and across these two domains.
