Many researches of drag reduction caused by cationic surfactants have been reported in recent years. However, there are few papers about the application of drag reduction for practical air conditioning systems. In this study, the effects of corrosion inhibitors on the drag reduction caused by a cationic surfactant, Ethoquad O/12, were experimentally investigated. Suitable corrosion inhibitors were proposed and significant change of rheological properties of surfactant solutions with the corrosion inhibitors was also indicated. Such drag-reducing additive was used for a practical air conditioning system, and the energy saving rates was experimentally obtained. Other ten examples of drag reduction adopted for practical systems were also presented in this paper.
