Abstract

Chilled water systems consume a significant portion of the energy in manufacturing, and inefficient operation could significantly influence utility bills and the environmental footprint of a facility. One way to ensure long-term energy-efficient plant operation is to ensure that chilled water system equipment, such as chillers, cooling towers, and pumps, are running at their best. Periodic operational assessments help to meet efficiency objectives for cooling plants. However, occasional set point and operational changes resulting from short-term fluctuations cause the plant operation to deviate from optimal. These changes accumulate over time, and operational efficiency deteriorates. Significant energy efficiency improvement potential in chilled water systems can be achieved by operational changes alone. Recent developments in information technology and the industrial internet of things data processing ability have overcome traditional problems and given rise to a new paradigm: monitoring-based commissioning (MBCx). Commissioning platforms and fault detection and diagnostics capabilities have evolved over time and presented more sophisticated abilities to efficiently control process cooling plants. The typical architectures of the MBCx process and a detailed approach to implement the process for chilled water systems are presented. A case study highlighting the energy-and cost-savings potential of MBCx systems is also presented.

Monitoring Based Commissioning: Benchmarking Analysis of 24 UC/CSU/IOU Projects

Technical Report Mills, Evan ; Mathew, Paul

Buildings rarely perform as intended, resulting in energy use that is higher than anticipated. Building commissioning has emerged as a strategy for remedying this problem in non-residential buildings. Complementing traditional hardware-based energy savings strategies, commissioning is a 'soft' process of verifying performance and design intent and correcting deficiencies. Through an evaluation of a series of field projects, this report explores the efficacy of an emerging refinement of this practice, known as monitoring-based commissioning (MBCx). MBCx can also be thought of as monitoring-enhanced building operation that incorporates three components: (1) Permanent energy information systems (EIS) and diagnostic tools at the whole-buildingmore »« less

Industrial central chiller facility upgrade for greater system capacity and tighter process control

Conference Lizardos, E J

An existing 3,000 Ton single-stage central chilled water system at a Wyeth-Ayerst pharmaceuticals plant could not balance and deliver required chilled water flow rates in an energy efficient manner, especially so considering planned expansions in manufacturing operations. A modernization designs consisting of a two-stage primary and secondary pump design and a chilled water distribution and pressure equalization header resulted in an expandable, energy efficient chilled water system for existing and expanded manufacturing processes and building air conditioning. A constant-flow primary pump-chiller loop, independently interfaced to a variable-flow secondary pump supply loop provides energy-efficient constant-flow control of chiller operations, while providingmore »« less

Loop chiller plant design dramatically lowers chilled water costs

Conference Hartman, T

Recent improvements in HVAC networking and speed control technologies, together with an improved understanding of the nature of cooling loads in buildings offer exciting opportunities for improving the energy efficiency of chiller plants. A new Loop chiller plant design has been developed that incorporates variable speed control on all plant components. Operation of this cooling plant is coordinated with the load it serves through a control network. This new approach has enormous advantages over traditional optimized plants. The two key advantages of these new Loop design chiller plants designs are: (1) Annual operating energy requirements are reduced by as muchmore »« less
