CPD Presentation Evaporative cooling in data centresColt UK
Data centres that use evaporative cooling can cut their energy bills by up to 80% compared to conventional cooling methods!
The specifications for the environmental operating conditions of IT equipment used in data centres have recently been revised, opening the way to evaporative cooling in such buildings. Evaporative cooling can provide a highly effective solution, with low installation and running costs, minimal maintenance requirements and quiet operation.
This seminar covers:
• Revisions to the specifications for the environmental operating conditions of IT equipment in data centres
• Options for cooling in a data centre
• Implementing evaporative cooling in a data centre.
Industrial refrigeration systems are a significant consumer of electrical energy in food processing, cold storage, and chemical processing industries throughout the Midwestern United States.
This webinar, presented by Bryan Hackett, P.E., of kW Engineering, will covered the following topics:
• The basics of industrial refrigeration systems,
• A review of proven energy efficiency measures (EEMs) and how to identify potential applications for each, and
• The respective energy and cost savings for each.

The segmentation of data centers into alternating hot and cold aisles is an established best practice. A number of manufacturers are taking this premise of airflow separation a step further by marketing "containment" solutions. By containing the hot or cold aisle, the air paths have little chance to mix, presenting data center operators with both reliability and efficiency gains.

Air can be effectively cooled by exploiting the evaporation of water atomised into very fine droplets: the change in state, from liquid to vapour, absorbs energy from the air, which is consequently cooled. Evaporation of 100 kg/h of water absorbs 69 kW of heat from the air, for power consumption of less than 1 kW!. In an air handling unit, the supply air can be evaporatively cooled and humidified (direct evaporative cooling, DEC). Alternatively, if the outside air humidity is already high, the exhaust air can be cooled by several degrees without limits in terms of humidity, as it is discharged by the AHU; this cooling capacity, using a heat exchanger, can be used to cool the incoming fresh air with an efficiency that depends on the heat recovery unit used, yet easily exceeds 50%! (indirect evaporative cooling, IEC). All this means lower unit energy consumption and smaller dimensions and capacity of the cooling coil and chiller.

Data Center Cooling Efficiency, Optimization and Trade-offs
Learn how to lower Cooling costs 30-80% while increasing sustainability.
Gain insight on advantages and the trade-offs of the many technologies, where combinations of technologies may be best, and learn how cooling solutions play into the upcoming Title 24 Code changes.
From Best Practices, Containment (Hot vs. Cold, Passive vs. Managed, Chimney’s and IT Rows), Demand Based Cooling (Managed Distribution), new High Efficiency In Row Cooling (close coupled) technologies (CMS designs = 40% - 60% more efficient), new High Efficiency CRAC/H’s (CMS designs = 40-50% more efficient).
When developing data center energy-use estimations, engineers must account for all sources of energy use in the facility. Most energy consumption is obvious: computers, cooling plant and related equipment, lighting, and other miscellaneous electrical loads. Designing efficient and effective data centers is a top priority for consulting engineers. Cooling is a large portion of data center energy use, second only to the IT load. Although there are several options to help maximize HVAC efficiency and minimize energy consumption, data centers come in many shapes, sizes, and configurations. By developing a deep understanding of their client’s data center HVAC requirements, consulting engineers can help maintain the necessary availability level of mission critical applications while reducing energy consumption.

2. The Facts Energy costs are rising The cost to power and cool server room equipment now exceeds the purchase cost on a 3-year life-cycle, based on a traditional server room / data centre configuration.
4. • Reduce energy usage • Create more efficient rack space Cooling Solutions The Aim The government will be introducing a carbon tax in 2009 All companies will have to report power usage by law
5. Recent studies reveal that data centre power densities have increased ten-fold in the last 10 years and that cooling represents upwards of 60-70% of the total data centre power spend for the majority of customers. These costs are driven by the data centre power requirements and the volume of cooling airflow required Source HP Industry Studies

7. 38-42 o C 32 o C It is not only direction of airflow that must be taken into consideration, but also temperature rise across the server and the air volume required by the server fans. Blade servers are the most electrically efficient form of server. Available blade types for a given blade server system can vary dramatically in performance and power consumption Cooling Solutions 49.6 l/s/kW (223.2 l/s @ 4.5kW) Typical 7U Blade Server 22 o C Typical 1U Server 75.5 l/s/kW 22 o C
8. The predominant architecture for cooling data centres since the inception of the mainframe has been raised floor air delivery from perimeter computer room air conditioners (CRAC). At lower densities (1 – 5 kW / rack), adequate cooling is provided to IT equipment, despite the mixing of air throughout the room. Existing Configurations Room Based Cooling

Fact 1: Power and cooling costs increasingly limit scalability of your data center, and consume an ever-larger share of budget resources. The 3-year energy cost of highly dense servers is roughly equivalent to their acquisition cost. 1 Fact 2: Advances in compute density, such as blade servers, have resulted in highly dense servers that require significantly more power and cooling than traditional server configurations. Industry analyst Gartner wrote, “The leading server vendors recognize the problems associated with highly dense hardware and, in particular, with the rapid uptake of high-density blades. As such, they are attempting to develop solutions to deal with those problems.” 2 Fact 3: The power and associated costs to cool the datacenter can be as much or more than the cost of powering the IT equipment (servers, storage, and networking). [3] A study by HP and The Uptime Institute suggests that in a majority of the world's data centers 63% of a datacenter’s power is associated with the power of cooling the IT equipment. 4 While the rest of the industry is narrowly focused on only one aspect of the problem -- reducing the power of chips and other components, HP is also addressing the need to reduce the power requirements and costs associated with cooling the datacenters themselves. Fact 4: Reducing the energy required to cool a datacenter can result in significant cost savings (and reduction in CO2 emissions) or the ability to deploy more IT equipment in the same space -- or a mixture of the two.
Why The onset of high density computing including blades
Blade servers both offer increased computing density and a significant performance per watt benefit. These inherent advantages of blades when matched with advanced power and cooling infrastructure, can assist to drive out waste in the physical environment and drive up efficiencies.
Major obstacle is the length scale of air delivery - distance between cooling units and heat load make it difficult to properly remove the heat generated from IT equipment without mixing with supply air - results in hot spots and a complicated design approach to air distribution
