Energy has been described as "that which makes things go". Air conditioning accounts for 1/3 of the total energy use in society. Further, ventilation air accounts for 20-40% of the cooling load for HVAC (Heating, ventilating, and Air conditioning) industry. The ratio can be even higher in hot and humid regions where latent load from fresh air is as heavy as 50% of the cooling load. In this book, the systems and performances used for total heat recovery are introduced. They can be classified into two categories: energy wheels and stationary total heat exchangers. Energy wheels and membrane based total heat exchangers are specially described. Heat and mass transfer modelling of the system are performed. Influences of key material and design parameters on the system performance are discussed. Novel membranes including hydrophobic-hydrophilic composite membrane and composite supported liquid membrane are developed for total heat exchangers and are characterised. Sorption and diffusion of moisture in hygroscopic materials are the key parameters influencing latent heat recovery capability. Their appraisal methods are provided and implemented. Besides materials side intensification, air side intensification measures are taken as well. Plate-fin and cross corrugated triangular ducts are two important structures that are introduced. Plate-fin is compact and mechanically strong. Cross-corrugated triangular ducts are a new type of primary surface heat mass exchanger. The basic transport data in these structures are provided. Convective heat and mass transfer coefficients in plate-fin ducts of finite fin conductance with various cross sections are numerical obtained. Fluid flow and heat transfer in cross-corrugated triangular ducts are estimated by considering laminar, transitional, and turbulent complex flow regimes. Based on the fundamental heat mass transfer data, the book illustrates some examples of the applications of total heat recovery in novel HVAC systems. Chilled-ceiling combined with desiccant cooling and independent air dehumidification are two pioneering trends in air conditioning industry. They overcome the shortcomings of conventional all air systems by decoupling the treatment of sensible load with latent load. Partial or full total heat recovery are realised in combination with these novel systems, which contribute to reduced energy use with increased indoor humidity control, even in transit seasons when traditional air conditioning systems fail to control humidity. The component modelling of various key equipments like refrigeration cycle, heat pumps, regenerative wheels, heat exchangers, cooling coils, are conducted to estimate their energy performance and their effects on indoor thermal and humidity performance. The book combines theoretical analysis with engineering practices. It covers a wide range of knowledge from fundamental heat mass transfer data to novel systems design and performance analysis, from materials synthesis, characterisation to thermodynamics and fluid dynamics. As a kernel part, numerical heat mass transfer provides the tool for component modelling. The book provides crucial insight and design guidelines for the total heat recovery focused air conditioning industry.

The art and the science of building systems design evolve continuously as designers, practitioners, and researchers all endeavor to improve the performance of buildings and the comfort and productivity of their occupants. Retaining coverage from the original second edition while updating the information in electronic form, Heating and Cooling of Buildings: Design for Efficiency, Revised Second Edition presents the technical basis for designing the lighting and mechanical systems of buildings. Along with numerous homework problems, the revised second edition offers a full chapter on economic analysis and optimization, new heating and cooling load procedures and databases, and simplified procedures for ground coupled heat transfer calculations. The accompanying CD-ROM contains an updated version of the Heating and Cooling of Buildings (HCB) software program as well as electronic appendices that include over 1,000 tables in HTML format that can be searched by major categories, a table list, or an index of topics. Ancillary information is available on the book’s website www.hcbcentral.com From materials to computers, this edition explores the latest technologies exerting a profound effect on the design and operation of buildings. Emphasizing design optimization and critical thinking, the book continues to be the ultimate resource for understanding energy use in buildings.

The comfort of interior rooms depends on temperature, humidity, and an adequate supply of fresh air. Depending on use and climatic conditions, technical systems of varying complexity are required to achieve it. Basics Room Conditioning provides a basic understanding of these relationships and uses diagrams to explain the different possible levels of space conditioning – from simple principles of housing construction to totally air-conditioned systems that are fully independent of outside air.

Heating Ventilation and Air Conditioning by J. W. Mitchell and J. E. Braun provides foundational knowledge for the behavior and analysis of HVAC systems and related devices. The emphasis of this text is on the application of engineering principles that features tight integration of physical descriptions with a software program that allows performance to be directly calculated, with results that provide insight into actual behavior. Furthermore, the text offers more examples, end-of-chapter problems, and design projects that represent situations an engineer might face in practice and are selected to illustrate the complex and integrated nature of an HVAC system or piece of equipment.
