In this work, the main focus is given to efficient use of chilled water, with opportunities for reuse/recycle explored in order to lower the overall chilled water flow rate supplied to the network. Based on a superstructure that includes all possible network connections, mathematical models are developed for different integration schemes. Other than minimizing the chilled water requirement, a conflicting objective is included in the model to reduce network complexity and to improve flexibility. The design problems are formulated as mixed-integer nonlinear programming models. Two industrial case studies are used to illustrate the proposed approach. ? 2013 Published by Elsevier Inc.Chilled water networkMixed-integer nonlinear program (MINLP)Process integrationResource conservationSuperstructure modeling[SDGs]SDG6journal article10.1016/j.applthermaleng.2013.04.0242-s2.0-84878842447https://www.scopus.com/inward/record.uri?eid=2-s2.0-84878842447&doi=10.1016%2fj.applthermaleng.2013.04.024&partnerID=40&md5=c785c18a2bf94ed83e89b176d650f0c1
