Air Conditioning with Natural Energy: Applications, Case Studies, and Energy Savings Potential is a comprehensive examination of the principles, theory, applications, and energy saving performance of newly developed technologies for air conditioning using natural energy. Based on the latest research and real-world case studies from North America, Europe, and China, the book provides an engineering perspective on the design and application of air conditioning from multiple climates. Each case study presented analyzes the carbon emission reduction potential, energy saving potential, and the operational performance of the technologies.
Specific chapters examine the range of air conditioning technologies that use natural energy. This includes enhanced treatment technologies for outdoor air such as earth-to-air heat exchanger, fresh air pre-handling system using shallow geothermal energy, as well as newly developed technologies such as pipe-embedded wall, nocturnal cooling wall, and pipe-embedded window systems. With particular focus on applications in China, Part II provides real world case studies from multiple climatic zones, demonstrating the practical application and implementation of these technologies.
