The ECHO system monitors and controls temperature, airflow and pressure; ensuring the right air temperature, in the correct quantity and at the correct pressure is presented to the server inlet, enabling the utmost of efficiency. By varying airflow, ECHO operates not only with air volumes 50% less than traditional cooling systems but also much more efficiently and with elevated water temperatures that allow up to 95% free cooling (London, UK). In the following presentation which took place at Airedale International Air Conditioning's Head Office, Leeds, UK; Paul Oliver (Airedale Sales Director) and Tom Absalom (JCA Managing Director) will provide you with a detailed insight into the ECHO IT cooling system and how it can provide up to 95% free-cooling and a PUE of 1.2, providing outstanding energy efficiency, reduced operational costs and carbon impact. Full explanations of the products and controls involved are presented and an Illumina case study will profile real-life energy savings and benefits.

- Buying &quot;Green&quot; Vendors in many industries claim to sell 'green' products The problem is that without clear measurement and assessment, these claims can be meaningless Examples - are these items &quot;Green&quot;? Lexus 4*4 Hybrid Motorola 'Red' mobile phone Heavily packaged luxury organic food (e.g. Duchy Originals) Organic cigarettes Poland Spring 'ecoshape' plastic bottle, labelled 'a little natural does a lot of good' In data centre heat management, some vendors are claiming to be offering desirable green features Without understanding how to compare performance, it is impossible to adequately assess claims e.g. comparing the mileage that cars get, without a shared definition, every car can claim to get great mileage: Urban Inter-Urban Mixed
- Design for a purpose A ‘super car’ (MacLaren MP4-12C for example) is designed to perform very well at high speeds and is very much ‘at home’ on the race track. Whilst it can drive at 30mph, the designers wouldn’t have had this as their primary consideration. (a bit like the school run for the Chelsea tractors) . A smaller town car (eg Ford Focus) would be capable of driving at high speeds but its primary design considerations wouldn’t have been to chase a MacLaren supercar around a racing circuit.
- It doesn't make sense to pick a car based just on how good it is when travelling at 120mph - as that isn't how most people normally use their cars To help us choose a car, manufacturers make lots of figures available to us, not least of all those on fuel efficiency - Urban, Extra-Urban, and Combined figures. These figures indicate how efficient the car is likely to be - but only when driven in a particular way. If the car is to used differently to those styles given in the sales brochure, we wouldn’t expect the fuel economy figures given by the manufacturer to be met. So how else might we like to drive the car For example, always being driven up and down steep hills For example, with sumo wrestlers inside For example, driven at 5mph for the first year For example car driven in N Europe – Low ambient as opposed to Desert None of these driving situations are likely to be illustrated by the car manufacturers. Operational costs increase significantly because vehicle not operating at design conditions!
- Data centres don't all just need to go 'flat out' (to extend the parallel, it isn't like driving at 180mph all the time) When a data centre is opened, it is likely to run at a fraction of the maximum design and may take several years to approach the installed capabilities of the DC. Many data centres never even reach their maximum design parameters
- The PUE value of a DC gets worse as the load gets further away from the design maximum. Why? When the load is less, we’re still pumping power into the CRAC fans, pumps, UPS, lights etc and as the load approaches zero, the PUE will go to infinity. What we want (desire) is for the PUE to be as low as possible at all loads, not just when the load is high. Part load PUE is often much higher than expected when the data centre is partially loaded.
- Efficient components used efficiently Dynamic performance Free Cooling Bespoke Solutions
- Taking Advantage of Ambient Temperatures [See image at DCD 09 ppt v3.ppt slide 1] [See 'freecool_sim_v1' movie, from e.g. 1' 45'' to 1' 55''} Image shows data centre from above; servers are in the middle of the aisles; cooled by rear door heat exchangers (heat is removed to left of servers as viewed in image) At the top of the image, six computer room air conditioning units can be seen Outside the data centre, air conditioning units designed to take advantage of free cooling Free cooling works by taking advantage of the ambient temperature being cooler than the temperature in the data centre. By sending glycol into the outside units, this liquid gives up its heat to the colder outside air, enters back into the DC cooled, and this is used to take heat energy (load) from the data centre
- All Free Cool Systems are Not Equal See 'Lo Energy Solution 01.ppt' slide 7 This graph is for a different example (need 800kW of cooling, not 600kW) Need to draw similar graph onto slide 21, to show the contributions needed from free cooling and chiller cooling to deliver required capacity in our example With Non-concurrent free cooling, if free cooling can't deliver 100% of the required capacity, 100% of capacity is delivered by mechanical cooling There is no ability to 'mix' free and non-free cooling So, as soon as the ambient temperature hits 9C, all cooling is mechanical, none is free
