You need Data Center Cooling Optimization IF:

NOW, SEE THE AIR! Our Patent Pending DAMM cart provides a revolutionary view of data center air flows! At a fraction of the cost of CFD, we produce 3D maps of actual air flow in the data center. These maps combine air flow velocity, direction, temperature and humidity. We can quickly and accurately demonstrate air flows in the data center. Short cycling, mixing, ineffective CRAC placement and more can be easily seen.  In the example above, air flows out of the center hot aisle and is drawn into the adjacent cold aisle. Inadequate tile air flow forces servers to draw exhaust air from the adjacent hot aisle back to the cold aisle. Arrow length shows velocity, color indicates temperature.

  • You lose a single CRAC, you cannot maintain local rack inlet temperatures
  • You can no longer grow your data center due to insufficient cooling capacity
  • You are sub-cooling your data center to avoid local hot spots
  • You are getting constant hot spot alarms
  • Your energy costs are out of control

These problems develop as data centers evolve from their original design. Data Center Cooling Optimization re-enables efficient cooling by delivering cooling just where it is needed and eliminating inefficiencies resulting from leaks, short cycling, recycling and improper cooling set points. Substantial improvements can typically be realized in legacy data centers with minimal investment.

New Measurement Technologies Yields Big Savings:

We can reduce your cooling costs by 20% or more by optimizing the operation of your existing infrastructure. We enable greener, more reliable data centers that deliver the right cooling just where it is needed.

The Benefits:

The data center will achieve Reduced Operating Costs, Increased Cooling Capacity, Greater CRAC Redundancy, Improved Equipment Reliability.

In order to optimize cooling in the data center, you need to know where the cooling loads are located and you have to know where cooling capacity is delivered. If cooling capacity location and delivery is not matched to cooling loads, than optimization cannot be achieved.

We don’t speculate about energy use in your data center—
We measure it with revolutionary tools!

In order to optimize cooling in the data center, you need to know where the cooling loads are located and you have to know where cooling capacity is delivered. If cooling capacity location and delivery is not matched to cooling loads, than optimization cannot be achieved.

You must also know when inefficient air flow patterns and operational practices are reducing available cooling capacity. These data center characteristics must be acquired through comprehensive measurements.

Once acquired, the measured data may be used to produce engineered and modeled solutions. Without the data, any solution approach is merely a guess.

Revolutionary Thermal Imaging-Rack inlet temperatures are the critical indicator of cooling air effectiveness. With our pioneering mosaic thermal images, we measure, quantify and index every square inch of rack inlet. We can determine cooling performance referenced to ASHRAE or any other standard. In the bottom image, all orange surfaces exceed recommended ASHRAE rack inlet limits.

Our Measurement Process

Rack Metrics:
We have developed innovative Infrared temperature mapping techniques that produce temperature readings of every square inch of server inlets. Computer analysis of infrared mosaic images allow us to readily measure the effectiveness of cooling air delivery and produce quantitative performance metrics.

Air Distribution Metrics:
How much air is moved and where does it go? We measure energy performance and efficiency of CRAC units. Measurements include air flow, humidity, temperature and power. We use these data to calculate heat transfer and COP for every unit. We measure air flows at every perforated tile that serves a rack.

Rack Energy Requirements:
We measure power requirements for racks.

Air Flow Mapping:
We use our patent pending DAMM Cart to find efficiency robbing air flow patterns throughout the data center. Our unique data display permits visualization of leak-age, short cycling, recycling and flow obstructions. Our visualization is crucial to convincing decision makers that problems exist and must be corrected!

Solutions

Using this data, we develop improved CRAC and perforated tile layouts, recommend leak remediation steps, design air barrier schemes and more. This is the low cost, low hanging fruit of improved operation.   The greatest improvements in cooling efficiency are realized by achieving the highest possible rack inlet temperatures and the lowest humidity levels.  We will simulate both air flow and CRAC operation to calculate optimal  set points for both temperature and humidity.   Importantly, we calculate the impact of our recommendations on operating costs and capacity availability using our sophisticated, proprietary CRACSYM  model.

The Final Step

Upon implementation of recommended actions, we can obtain new benchmark data to document the level of achieved savings and improved cooling efficiency.
