2023615 · To find operation strategies with high energy saving potential, Qiu et al. [24] identified and optimized the sequencing control of the chiller plant and the
Abstract: Given high energy costs of chiller plants, plant operation optimization is important. Optimized results may not satisfy actual demand if ignoring input uncertainties.
2016611 · The following best practices can improve chiller performance and reduce operating costs: Operate multiple chillers for peak efficiency: Plants with two or more chillers can save energy by matching the building loads to the most efficient combination of one or more chillers. In general, the most efficient chiller should be first one used.
A chiller provides consistent temperature and pressure to your industrial process. Eliminating temperature and pressure variables simplifies the process development and optimization, ensuring the highest quality product. Instead of a wasteful, single-pass-through system, a chiller recirculates the cooling water.
