Available in PDF, EPUB and Kindle. Book excerpt: The term Air Handling System' refers to the equipment where air is conditioned to an acceptable level for distribution within the building. An air handling unit often abbreviated as AHU is a very important component of central-air-conditioning system. It is responsible for drawing return air from the indoor spaces, mixing it with outdoor air, conditioning it to the acceptable level for distribution within the building. The modular packaged equipment offered by various manufacturers is pretty standard. HVAC designers can simply spec the performance requirements and pick and choose from a wide array of standard building blocks to assemble a unit that meets their specific project needs. But large majority of air handlers are custom built or tailor made demanding HVAC designer to apply fundament psychrometrics processes to precisely estimate the capacity and airflow requirements, select the fan, coil and other auxiliaries and integrate these properly to the building control system. This 6-hr Quick Book outlines the key design considerations for sizing, selecting and estimating the capacity and airflow rate of air handling systems.At the conclusion of this quick book, the reader will be able to answer: * What is function of Air handling unit and what factors affect its sizing?* How are air-conditioning processes depicted on the psychrometric chart?* What is difference between room sensible and grand sensible heat factor?* How is airflow rate and the cooling coil load determined?* What are the five basic AHU arrangements?* What are the different types and applications of the fans used in air handling applications?* What are the different types of cooling and heating coils?* What are the different types and applications of the filters used in air handling applications?* What are the different types of humidifiers and dehumidifiers?* What are the different types of control valves and their application?* How are the air handling unit controlled and the sequence of operation for critical facility?* What are the energy conservation features in designing air handling systems?

Book excerpt: Guaranteeing a high system performance over a wide operating range is an important issue surrounding the design of automatic control systems with successively increasing complexity. As a key technology in the search for a solution, advanced fault detection and identification (FDI) is receiving considerable attention. This book introduces basic model-based FDI schemes, advanced analysis and design algorithms, and mathematical and control-theoretic tools. This second edition of Model-Based Fault Diagnosis Techniques contains: • new material on fault isolation and identification and alarm management; • extended and revised treatment of systematic threshold determination for systems with both deterministic unknown inputs and stochastic noises; • addition of the continuously-stirred tank heater as a representative process-industrial benchmark; and • enhanced discussion of residual evaluation which now deals with stochastic processes. Model-based Fault Diagnosis Techniques will interest academic researchers working in fault identification and diagnosis and as a text it is suitable for graduate students in a formal university-based course or as a self-study aid for practising engineers working with automatic control or mechatronic systems from backgrounds as diverse as chemical process and power engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Air Handling Units (AHUs) An Air Handling Unit (AHU) is a critical component in heating, ventilation, and air conditioning (HVAC) systems. These units are used to regulate and circulate air as part of a heating, ventilating, and air-conditioning system. Components of an AHU Blower/Fan: Moves air through the AHU and ductwork. Heating/Cooling Coils: Heat exchangers that transfer heat to or from the air passing through them. Filters: Remove particles and contaminants from the air. Humidifiers/Dehumidifiers: Control the humidity level in the air. Mixing Box: Combines return air with fresh air. Dampers: Control the flow of air within the system. Control Systems: Include sensors, thermostats, and controllers to regulate temperature, humidity, and airflow. Types of AHUs Draw-Through AHUs: The fan is located after the air-handling components (such as coils and filters), drawing air through them. Blow-Through AHUs: The fan is located before the air-handling components, blowing air through them. Functionality Ventilation: AHUs bring in fresh air from outside and expel stale air from inside, ensuring indoor air quality. Temperature Control: By heating or cooling the air, AHUs maintain desired indoor temperatures. Humidity Control: Adding or removing moisture from the air to maintain comfortable humidity levels. Air Filtration: Removing dust, pollen, and other airborne particles to improve air quality. Applications Commercial Buildings: Offices, shopping malls, hospitals, and schools where maintaining a comfortable and healthy indoor environment is crucial. Industrial Settings: Factories and laboratories that require precise environmental control to ensure product quality and safety. Residential Buildings: High-end homes and apartment complexes that need advanced climate control and air quality management. Benefits Energy Efficiency: Modern AHUs are designed to be energy-efficient, reducing operational costs. Comfort: Maintain consistent and comfortable indoor environments. Health: Improve indoor air quality by filtering pollutants and controlling humidity, which can reduce the prevalence of mold and allergens. Flexibility: Can be customized to meet the specific requirements of different buildings and applications. Maintenance Regular maintenance is essential for the efficient operation of AHUs. This includes: Filter Replacement: To ensure air quality and system efficiency. Coil Cleaning: To maintain heat exchange efficiency. Fan Maintenance: To prevent mechanical failures and ensure proper airflow. Checking Control Systems: To ensure they are operating correctly and responding to environmental changes. Conclusion Air Handling Units are vital for creating and maintaining comfortable, healthy, and efficient indoor environments in a variety of settings. Understanding their components, functionality, and maintenance requirements can help optimize their performance and extend their lifespan.

Available in PDF, EPUB and Kindle. Book excerpt: Supervision, condition-monitoring, fault detection, fault diagnosis and fault management play an increasing role for technical processes and vehicles in order to improve reliability, availability, maintenance and lifetime. For safety-related processes fault-tolerant systems with redundancy are required in order to reach comprehensive system integrity. This book is a sequel of the book “Fault-Diagnosis Systems” published in 2006, where the basic methods were described. After a short introduction into fault-detection and fault-diagnosis methods the book shows how these methods can be applied for a selection of 20 real technical components and processes as examples, such as: Electrical drives (DC, AC) Electrical actuators Fluidic actuators (hydraulic, pneumatic) Centrifugal and reciprocating pumps Pipelines (leak detection) Industrial robots Machine tools (main and feed drive, drilling, milling, grinding) Heat exchangers Also realized fault-tolerant systems for electrical drives, actuators and sensors are presented. The book describes why and how the various signal-model-based and process-model-based methods were applied and which experimental results could be achieved. In several cases a combination of different methods was most successful. The book is dedicated to graduate students of electrical, mechanical, chemical engineering and computer science and for engineers.

Book excerpt: Composed of three sections, this book presents the most popular training algorithm for neural networks: backpropagation. The first section presents the theory and principles behind backpropagation as seen from different perspectives such as statistics, machine learning, and dynamical systems. The second presents a number of network architectures that may be designed to match the general concepts of Parallel Distributed Processing with backpropagation learning. Finally, the third section shows how these principles can be applied to a number of different fields related to the cognitive sciences, including control, speech recognition, robotics, image processing, and cognitive psychology. The volume is designed to provide both a solid theoretical foundation and a set of examples that show the versatility of the concepts. Useful to experts in the field, it should also be most helpful to students seeking to understand the basic principles of connectionist learning and to engineers wanting to add neural networks in general -- and backpropagation in particular -- to their set of problem-solving methods.

This book was released on 2022-03-25 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explore how exergy analysis can be an important tool for assessing the sustainability of buildings. Building's account or around 40 percent of total energy conditions depending on local climatic conditions. Due to its nature, exergy analysis should become a valuable tool for the assessment of building sustainability, first of all considering their scope and the dependence of their energy demands on the local environmental and climatic conditions. Nonetheless, methodological bottlenecks do exist and a solution to some of them is proposed in this monograph. First and foremost, there is the still-missing thermodynamically viable method to apply the variable reference environment temperature in exergy analysis. The monograph demonstrates that a correct approach to the directions of heat exergy flows, when the reference temperature is considered variable, allows reflecting the specifics of energy transformation processes in heating, ventilation, and air conditioning systems in a thermodynamically viable way. The outcome of the case analysis, which involved coordinated application of methodologies based on the Carnot factor and coenthalpies, was exergy analysis indicators – exergy efficiency and exergy destroyed – obtained for air handling units and their components. These methods can be used for the purposes of analysing and improving building technical systems that, as a rule, operate at a variable environment temperature. Exergy analysis becomes more reliable in designing dynamic models of such systems and their exergy-based control algorithms. This would improve the possibility to deploy them in building information modelling (BIM) technologies and the application of life cycle analysis (LCA) principles in designing buildings, thus improving the quality of the decision-making process. Furthermore, this would benefit other systems where variable reference environment plays a key role. This book is relevant to academics, students and researchers in the field of thermodynamic analysis considering HVAC equipment, building energy systems, energy efficiency, sustainable development of technical systems of energy, mechanics, and construction, as well as preservation of natural resources. Planners, designers, engineers of HVAC equipment, building energy systems, and developers of appropriate simulation tools (e.g., BIM) will also find it of use.
