Caleffi's ‘Circulation in Hydronic Systems’
Caleffi’s 16th edition of idronics explains how circulators operate, as well as how they are sized and selected, which is crucial to good hydronic system design. It focuses on determining proper flow rates in different portions of a hydronic system. Once determined, piping and circulator selection is explored to ensure that the flow rates occur when the system is built and commissioned. The journal discusses circulators and how they interact with other system components.
