Cooling Systems

  1. Don't believe everything you see or read

    I was reading some literature that was touting the use of an overhead power distribution system. It made its case for overhead cabling mostly by pointing out the potential risks related to restriction and obstruction of airflow as the result of leaving abandoned cables under floor and not having an organized cabling system. And then to drive their point home...
  2. Renewable Energy - Data Centers Doing Their Part

    A recent article in Clean Technica Renewables Could Generate 48% of ICT (Information and Communication Technology) Industry's Power Supply by 2020, shares some interesting statistics compiled by the EPA's Green Power Partners program. Based on the reports small sample size, the percentage of renewable energy used to power tech and telecom (data centers) is over 30%. That's a pretty big...
  3. Selecting a Hosting Data Center

    More and more businesses, large and small, are beginning to reach a point where their data needs have outstripped their in-house computing capabilities. Instead of spending the capital or devoting resources to upgrade their infrastructure, they are seriously considering contracting with a retail data center to host their data. Your concerns when outsourcing data hosting are the same as when...
  4. Taking Advantage of Free Cooling

    First off free cooling isn't free it would better described as reduced cooling. My data centers were located in Minnesota so we were able to take advantage of the outside temperatures for a good part of the year. Two of our sites utilized CRAC units with compressors to cool raised floor space. We set our wet cooling towers to make...
  5. Data Center Environmental Monitoring

    Selecting a Monitoring System Monitoring can range from electrical power equipment supporting critical load such as UPS systems, diesel generators, PDU/RPP’s down to individual branch circuits within power panels. When evaluating a monitoring system consider what type of graphics are desired and available.  Pictorial diagrams displaying individual monitored components are helpful, especially ones that change color or light up in...
  6. Cooling Equipment Maintenance Checklist

    Proper maintenance of cooling equipment will not only extend their life but also cut operating costs in the data center.  Remember cooling cost typically account for 40% of a data centers electrical expenses. Dirty or poorly maintained cooling equipment will not only decrease your cooling efficiency, contributing to lost capacity, but it also runs the risk of failure leading to...
  7. Cooling Tower Spring Time Start-Up

    Cooling Tower Spring Time Start-Up Typically in the northern climates cold winters reduce the need for cooling capacity permitting many data centers to take cooling towers off-line.  If you performed an off season lay-up of a cooling tower to help prevent corrosion and bacterial growth, then you are well on your way to a spring start up. Even though you’ve...
  8. Cooling Tower Off Season Layup

    Cooling Tower Off Season Layup “Chlorine is a deadly poison gas employed on European battlefields in World War I. Sodium is a corrosive metal which burns upon contact with water. Together they make a placid and un-poisonous material, table salt. Why each of these substances has the properties it does is a subject called chemistry.” ---Carl Sagan, Broca's Brain: The...
  9. Dangers of Bacteria 2

    The Dangers of Bacteria in a Data Centers Cooling System – Part 2. Data Center Cooling Systems - Dangers of Bacteria In the first part of our discussion on bacteria in a data centers cooling system, we covered the health risk dangers of Legionella bacteria, the corrosive nature of slime forming microorganisms that contribute to microbiologically influenced corrosion (MIC), and...
  10. Dangers of Bacteria 1

    The Dangers of Bacteria in a Data Center Cooling System When it comes to water treatment programs, one of the biggest concerns in a data center is dealing with microorganisms and the biological controls within your open cooling tower systems. Why you ask? Because of the dangers of bacteria! Legionella Pathogenic bacteria, like Legionella, thrive in open condenser/tower systems.  Legionella bacteria...
