Over the past decades, great progress has been made in both Indirect Evaporative Cooling (IEC) technology R&D and its commercial application. The book proposes a novel dew point air cooler (DPC) which achieves breakthroughs in cooling performance and energy use by incorporating a variety of innovation into a counter-flow regenerative unit. It features an innovative structure of the heat and mass exchanger, a novel water distribution and control scheme, the application of new material and new process and an exclusive self-developed simulation tool. The book presents an in-depth investigation of the novel DPC that is undertaken through an extensive and critical literature review, optimal concept design, theoretical analysis, development of dedicated simulation programme, prototype construction, laboratory-controlled tests, validation of the simulation models and socio-technical acceptance analysis. A significant leap forward has been achieved with this study and this is expected to open enormous global business in the very near future, thus bringing about great economic, environmental and sustainability benefits worldwide.

This book discusses the relationship, interaction and conflict between everyday life and various institutions in a specific village in North China, with a focus on the formal and informal legal systems.
