CFD (Computational Fluid Dynamics)

Data centres host IT infrastructure that keep businesses operational and are considered mission critical facilities by most organizations. Down time in a data centre is catastrophic for most companies. Ainsworth's CFD (Computational Fluid Dynamics) services identifies and helps resolve data center airflow issues, yield significant energy savings and improved efficiency.


Ainsworth’s FlowLogix Approach

Ainsworth’s FlowLogix approach is one that can help identify any problems or inefficiencies that data centers are undergoing, as well as customized solutions to help fix them. The FlowLogix system is an innovative combination of CFD modeling, airflow management, and professional services that manage airflow in the data center and distribute it to the heat load. This ultimately decreases the overall kW draw, providing significant energy savings. Most importantly, all of this is accomplished without the installation of any additional CRAC units. The FlowLogix system Ainsworth provides is a five-step approach that in some way or another can benefit any data center manager’s situation. Whether or not that includes all five steps, or a combination of a few, FlowLogix is sure to deliver results that will make any data center manager look like an all-star employee.

STEP # 1 CFD(Computational Fluid Dynamics) Analysis

Illustrate how efficiently a room is operating from an airflow standpoint. Once the analysis is complete, Ainsworth can then engineer the FlowLogix solution to improve your data center’s specific conditions.

STEP # 2 Air Balances(For Sub-Floor Cooled Infrastructure)

Help slow down and balance the sub-floor air, deliver 90% + CFM through perforated tiles. Air balancers are strategically placed, using Ainsworth’s intellectual properties, to enhance and balance static pressure.

STEP # 3 Cold Air Management

Every data center space has its own unique characteristic. Since every environment is different, every data center requires a professional custom approach. Some of the techniques used in step 3 may include the following:

• Perforated tile management
• Addition of high-perforated tiles where needed
• Sealing of all unmanaged openings and cable cut-outs
• Cold aisle containment
• Blanking Panels

STEP # 4 Heat and Return Air Management

By using innovative approaches in eliminating the warm air from recirculating into the cold aisle, FlowLogix has delivered a 3 -11 degree drop in temperature in the cold aisle on average. From a cost perspective, it might be possible to eliminate one in five air handlers with the proper return air temperature. Ainsworth analyzes the most effective and efficient way of removing the warm return air from the data center.

STEP # 5 Environmental Monitoring

Ainsworth uses wireless temperature monitoring at the rack level to gain visibility to real-time equipment temperatures. Three key benefits of this FlowLogix component include:

1. Sensors provide real-time temperatures every 20 seconds.
2. Set thresholds to stay within ASHRAE standards for critical servers to proactively prevent equipment failures related to environmental conditions.
3. Through FlowLogix quarterly health check program, stay in control with real-time equipment temperatures and maximize energy savings.

 

Hopefully this quick overview is a useful reminder of Ainsworth’s unique approach and FlowLogix solutions for data center managers that are familiar with us. For those data center managers who have not been exposed to this innovative service, we hope that when trying to reduce your energy consumption and expenses you will keep the FlowLogix solution in mind and take into consideration the benefi ts that it may be able to provide to you.

Data Centre Assessment

Between HVAC, lighting, electrical systems and server infrastructure, most North American data centres consume more energy and require more maintenance than necessary… increasing your operating budgets more than necessary, too.
A Data Centre Assessment is the critical first step to reducing these costs.


As part of this process, Ainsworth will conduct thorough CFD, HVAC, electrical and thermal assessments of your facility, providing you with an accurate evaluation of energy usage, as well as areas where consumption can be reduced and downtime avoided.

We will also perform a risk assessment based on your needs today and your plans for tomorrow.


We will then recommend ways to help you take appropriate action, lower operating costs and qualify for financial rebates of up to 50% of project costs with the saveONenergy Retrofit program.


You can also take advantage of OPA capital funding to upgrade and replace critical infrastructure… and we’ll show you how. We can even show you how to save money on your Data Centre Assessment.

THERMAL AND CFD ASSESSMENTS

Determine how efficiently air flows through the data centre and how effectively heat is dispelled, and identify areas for improvement.

What we do

  • Measure air temperature and air flow at critical points throughout the data centre.
  • Identify hot spots and air flow restrictions.
  • Perform a CFD analysis in problematic areas. This is a rigorous means of evaluating airflow patterns and may include important variables such as air pressure, temperature and velocity.
  • Evaluate and assess the data.
  • Construct an “As Is” floor plan identifying issues with air flow, obstructions and other areas of concern.

What you get

  • An in-depth account of airflow characteristics.
  • A comprehensive report, including floor plan, which
    identifies problems and provides recommendationswith corresponding estimates.

HVAC AND ELECTRICAL ASSESSMENTS

A comprehensive assessment of the current infrastructure can identify what needs to be done to improve operating efficiencies and reduce downtime.

What we do

  • Evaluate existing mechanical and electrical equipment
    and identify potential single points of failure
  • Calculate the loads on each UPS and per-rack enclosure.
  • Identify potential areas for reducing energy consumption.
  • Analyze path redundancies.
  • Assess maintenance performed to date (scheduling, work, etc) and recommend the right approach to keep your data centre running at peak performance.

What you get

  • A detailed report outlining the current state of mechanical and electrical equipment, along with an assessment of how well the data centre is equipped to handle projected growth. The analysis will itemize all actionable items, including updated floor plans and single line diagrams, and provide related estimated costs.
