Efficiency and Reliability Joint Optimization of Chiller Plants Based on a Hybrid Model

RA-L 2019

Methods for chiller plant energy savings may increase component degradation, thereby decreasing reliability. Joint optimization is thus important. The problem, however, is challenging. First, existing reliability models which are functions of time in terms of years are not suitable for operation opt

Chiller Plant Operation Optimization With Minimum Up/Down Time Constraints

RA-L 2018

A chiller plant includes chillers, cooling towers, and pumps. Chiller minimum up/down times (MUDTs) are relatively long among a plant but short as compared with the time interval. MUDT constraints are generally ignored in optimization but handled heuristically. With the numbers of active units and n
