Computational Fluid Dynamics (CFD) Services

PTS utilizes powerful 3-D CFD software for the design, operational analysis, and maintenance for data center and computer rooms of all types and sizes. The intent is to provide better designs and management of mission critical facilities throughout their lifetime. Our goal is to minimize the risk of cooling problems as well as increase the overall manageability and performance of the site.

Computational Fluid Dynamics Modeling as a Design Tool

CFD modeling gives engineers the luxury to consider several design options in the minimum amount of time. As a result, the final design is not based on a tentative approach, but is a result of a professional design process considering several options and selecting the optimum solution. This can save on capital and operational costs as well as save time by avoiding mistakes and during commissioning.

The following is how PTS uses Computational Fluid Dynamics modeling in the data center design process:

1. Architectural Shell
2. Map Obstructions
3. Raised Floor & Suspended Ceiling Layout
4. Computer Room Air Conditioner (CRAC) Methodology
5. CFD Model
6. Model Analysis & Update
7. Site Engineering & Construction Documents

Room Types Supported by Computational Fluid Dynamics AnalysisOur software can analyze just about any cooling methodology and CRAC configuration including:

• Floor Room Cooling (no raised floor) with & without Ducted Supply and/or Returns
• Raised Floor Cooling with & without Dedicated Returns
• Room-Based Cooling Solutions
• Row-Based Cooling Solutions
• Rack-Based Cooling Solutions
• Cooling Optimization Solutions
• Economizer Cooling Solutions
• Heat Rejection Solutions

Computational Fluid Dynamics (CFD) Modeling

Computational Fluid Dynamics Operational Baseline Service

Once the design, engineering, construction, and commissioning is complete the data center can be made operational with introducing the equipment that will comprise the critical load. Building a CFD baseline of the cooling dynamics of the site is vital once the IT infrastructure has been populated.

The following is how PTS uses CFD modeling in the data center operations process:

1. Perform Site Survey & Equipment Mapping
2. Create Cabinet CFD Models
3. Create a Room CFD Model
4. Perform a Site Survey to Validate the Model
5. Make Necessary Adjustments to the Model

Cabinet CFD Modeling

The CFD software we use has the ability to analyze the characteristics of individual cabinets down to the equipment level. Vendor specific IT infrastructure or “kit” as it is referred to, can be loaded into a cabinet and analyzed to determine the temperature of the air entering and exiting the equipment. In fact, our software is complex enough to determine how variations in cabinet position, the use of blanking plates, and other factors will affect the cabinet’s cooling profile.

Maintaining a Computational Fluid Dynamics Modeled Computer Room

The integrity of the cooling behavior of a computer room is disrupted by its load growth. Operational changes to the room have a direct impact on the temperatures in the room. To ensure continued high performance of the site, it is necessary to predict the affect equipment changes will have on the site before they are implemented.

The following is how PTS uses CFD modeling during the data center maintenance process:

1. Provide the Client with a CFD Management Module

• Maintain a complete asset inventory log
• Maintain redundant and capacity cooling constraints of the facility

2. PTS Provides Periodic and/or Event Specific CFD Model Updates as the Operational Condition Changes

• Maintain a detailed change order log
