Editor's Notes
- Welcome & thank you. Time is a commodity in short supply so a big thank you for investing yours with usObjectives to discuss current trends and best practices in DC coolingProvide an opportunity to network with other people from the industry - have access to engineers from the manufacturer (no where else in UK for that)House keeping - Toilets - Fire AlarmsItems on chairs - Promotional bag – some literature and our new rebranding pack- Feedback form – please complete, leave on chairsAGENDA Best Practise - Introduction to AIAC / Aisle Containment (GRH) / Product Section (PIO)- Explore some scenarios / Meet the experts (The designers) - Please make you way round the products & test centre, 1 hoursLunch will be set out & served at 1:30pm then we’ll conduct factory tours in 2 groupsRed Tour (1)- Tony Cole, Blue Tour (2) – Mark Dowell
- Brand refreshed - Our brand is more than just our logo, it is how our customers perceive us, it’s our reputation, the way we work, and our company ethos.We want to continue to evolve with our customers and ensure that we remain well positioned to help you address the challenges of a rapidly changing market. This means taking the positives from what we currently do and what we’ve learnt during our forty years of experience and using them to build on our successes.
- Almost a 40 year history – never stayed still – continually improving and evolving to meet the ever increasing challenges and opportunities this industry throws at us.(describe the slide)PAC is at the heart of what we do – it’s our pedigree. There’s always new challenges with higher density cooling requirements.The future? Who really knowsThe future is hard to predict, = we have to be on our toes, flexible and quick to respond.
- 1997 – the worlds fastest super computer at SANDIA National Laboratories @ASCI RED’ - 1.8 teraflops - 150m² raised floor - 800kW cooling needed2006 – Sony playStation3 - 1.8 teraflops - 0.08m² - <0.2kW
- British with a Global presence – properly resourced. Providing back up & supportNo1 in PAC
- An impressive following
- No1 Chiller manufacturer in the UK - std cooling & free cool - 3 compressor platforms - leading the way with Turbocor & TCF
- Service plans – to suit all needs, from basic to fully comprehensive with SLA from 24 to 4 hoursOnsite ass’y – make a unit fit where it shouldn’t ! Or couldn’tLeading service levels – highly trained/skilled team of engineers (50 around the uk) – not tire kickers. Maintenance sheets are as comprehensive as the initial commissioning sheets.1st class spares service - good income stream, but its only good if the spares are in stock
- Efficient CRAC’s / Chillers/ InRak products? YesEfficient system? Maybe not. Easy to use effient components in a system – even easier to make them work inefficiently.System cover – CRAC’s – controlling airflow, const pressure, temp/hum. - Chiller s setpoints based on room demand not a fixed setpoint - Look at PDU’s, the Servers & Rack4 Yrs ago – 4 people in controlsToday, there’s 20. A reflection of the increasing level of expectation from within the DC industry. Also an opportunity for you.Live DEMO
- Use EC Fans where you can.Load vary, installed cooling system needs to be variable and designed to meet the demand = efficiency across the whole cooling capacity, not just a spot point.
- Use EC Fans where you can.Load vary, installed cooling system needs to be variable and designed to meet the demand = efficiency across the whole cooling capacity, not just a spot point.Efficient Fan UseFans us power in relation to the cube of their speedSo fans running at 80% speed use just 51% of the same fan running at 100%AC FANS are still being used, but in terms of development they’re being left behind. All new fan developments are going the EC route.
- Challenged ourselves – raised the bar very high.Efficiency is driving our industry – ours/your businessSet Large cooling coils for max heat transfer.Filters across the full area of the coil – lower pressure dropLower PD means less demand on power hungry fansTHE ONLY CRAC UNIT ON THE MARKET WHICH APPEARS ON THE ETL LIST (ECA)Use TANDEM SCROLL compressors = Hi part load EER’sEC Fans stdEasy maintenanceFan bearings
- FACELIFT due to ErP (Energy related Product directive)New MicroNew ColourNew FansVery cost effective
- DX Capacity = 52kWCh W is 60kW
- Microchannel Condenser coils EC Fans std optionRemember: not all FC chillers are equal
- 1, 2, 3 circuit cooling (9 comps) - great part load EER’sEEV’s across the range
- TurboCor Compressor – TT300 & TT350 – Oil Free, centrif compressorsNo oil contamination, no reduction in performanceHi part load EER’sCompressor enclosures – necessary for EMC compliance
- Depends on the infrastructure. NEW BUILD lends itself to all fresh air type cooling.Need to guarantee the quality of the outside air- contaminants / corrosive atmosphere- fire suppression considerations- filtration changes are costlyFacebook / Google / Amazon – may use FA systemsIndirect FA cooling is probably more interesting.
- AdiabaticFor Chillers – often used on older equipment selected at lower ambient temps. Adiabatic sprays often introduced to prevent HP trips.Generally the water used is UNTREATED but this seriously reduces the max operating hours to something <100hrs. Often associated with excess mineral deposits on the coil and nozzles.>100 hrs requires RO water (reverse osmosis )blended with tap water to achieve impurities to approx 75micoS = BIG PLANT.Wetted media- life span of media is limited- increased delta P on the coil- Geoclima method – tested by AIAC, reduction in condenser performance and EER values.
- As high as possible1decC increase in operating temp equates to approx 4% reduction in energy
- Use EC Fans where you can.Load vary, installed cooling system needs to be variable and designed to meet the demand = efficiency across the whole cooling capacity, not just a spot point.
- EER ?ESEER ?SEER ?
- Simple answer is proper S&M.Common problemsGas shortage. 10% reduction in gas = 20% increase in running costsDrifting superheat – too high, loss of performance too low – loss of compressorNot tyre kickers. Maint sheets almost the same as commissioning sheets
