Often, a central chilled water plant can be one of the most critical systems within a facility, especially during facility operations—so wouldn’t it be logical for the design and installation of these plants be considered critical as well?
Expecting a central plant to be reliable is a given, so it makes sense that the steps leading up to the startup of that first compressor be as reliable as possible, too. Putting standard work practices, pre-engineered sequences and documentation into place can go a long way in helping to ensure the reliability of the chilled water plant.
It should be no surprise that when critical systems are being developed, designers and engineers prefer to implement systems and designs that have been proven to be dependable. However, a previous design can rarely be replicated to a new system. Relying on a tool—or set of tools—to assist in designing layouts and sequences that are specific to the project can contribute to the success of the design. Better yet, having a tool that can take pre-engineered, proven, and tested sequences and systems and build them up in a modular fashion to obtain the overall design can be a great way to decrease time and increase reliability in the design phase.
With Trane Design Assist, a free web-based resource, the designer or engineer can select from hundreds of sub-sequences and systems to create thousands of different permutations of a system. Create these designs using industry proven strategies and standards through the tools configurations selections and customize design specifics to meet any project need. From Trane® Design Assist™, several design assets are created including guide specifications, sequences of operation, point lists, and flow diagrams. Knowing that the controls and system design has been carried out with proven elements gives peace of mind that a stable foundation has been set for a reliable plant.
Execution and Programming Phase
With the design documents in hand, it’s now time to transition to the on-site execution of the design. As part of this phase, the implementation of programming and controls sequences starts to take place. Similar to the design phase, having a set of reliable tools that couple the design phase to the execution phase are critical. The sequences and layouts produced from Trane Design Assist not only increase speed and reliability for the designer, but they also increase speed and reliability for the plant programmer since the programs and applications that are to be implemented have been built harmoniously. Having this large library of modular programs that can be built up to fix project and plant complexity creates the desired custom sequence as specified during the design phase.
