Abstract.The CoolToolsTM Chilled Water Plant Design and Specification Guide is
targeted to a technical design audience. It includes design issues such as selection of
coils, application of different piping distribution systems, design and applications of
controls, mitigation of low delta-t syndrome, and a myriad of other performance
critical issues. It also includes a section on Performance Specifications, which is
targeted to equipment specifiers, including engineers and facility purchasing agents. It
