Consulting Engineer
San Diego, CA

Verle Williams, a registered Professional Engineer and a Certified Energy Manager, is the owner and president of Utility Services Unlimited, a professional consulting firm specializing in energy efficient systems studies, designs and performance verification. Mr. Williams is a 1960 graduate of the University of Colorado at Boulder, with a BS in Mechanical Engineering, and a BS in Business.
Mr. Williams' specialty for 45 years has been automatic controls, their application to solve complex challenges, and their design for reliable and simplified operation. His consulting services have taken him into many complex plants and challenged him to get "out of the box" and think about solutions that are outside the normal procedures and systems format.
Mr. Williams has spoken on many energy related topics to many national society meetings, local technical society meetings, and civic organization meetings, and has written over 35 published articles and papers. He has taught energy conservation classes at the University of California, San Diego Engineering Extension College, North Seattle Community College, and miscellaneous refresher classes in the San Diego area. Mr. Williams is very active in local, regional and Society-level ASHRAE activities. He is a Fellow/Life Member of ASHRAE and has received numerous awards through the years. He is one of ASHRAE’s Distinguished Lecturers.

"A New Central Plant with No New Chillers!"

Energy consumption of chiller plants often goes unchecked. This area has literally been a gold mine of conservation opportunities for 99% of the chiller plants visited. Starting with the pumping system, what pressure differential is there? What is needed in the buildings or air handlers served? What about the devices absorbing the pressure differential? Are they needed or is there another way to accomplish the goal? Is there a balance between the required flow and the pumps installed? Is it a constant speed primary-secondary, a variable primary, or a constant primary-variable secondary pumping system? If it is variable speed pumping, what controls the speed of the pumps?
Did you know that you can tie all those building chillers and pumping systems together, without adding pumps, to serve the entire campus cooling needs? Whether an office complex, an industrial complex, or a university campus, the entire cooling load can be met by the chiller(s) within any building connected to the loop. This permits only one chiller to supply the cooling needs of all the operating building systems during light load conditions. As the load increases, another chiller system is added. Energy savings will normally repay the cost of installing the piping system within a very reasonable time.
How about the control system? Are the pumps controlled as one element of an integrated control system, one that reads the needs of the devices served to determine the pump speed and pressure differential? Can the operator easily diagnose the total plant operation with the control system central station? In case of an emergency, can one dial in and look at all systems from a laptop from off-site? Are the flow readouts reliable? Does the control system integrate directly with the chiller control system?
What are your concerns? How can those concerns be addressed? Does this system really work? Isn't this contrary to all we've learned for years about chiller plants and campus distribution systems? Is there variable water flow in the chiller? How can the system be balanced? Does it need to be balanced? How can it be controlled effectively? Does it require a full time control system operator?" These questions can be addressed at the meeting.
Want to talk about these systems? Come to the meeting and we’ll do just that.
