Book excerpt: Air conditioning systems play a crucial role in providing comfortable indoor environments, whether it's in residential, commercial, or industrial settings. Understanding the principles of psychrometrics is essential for designing, operating, and optimizing these HVAC (Heating, Ventilation, and Air Conditioning) systems effectively. Psychrometrics is the study of the thermodynamic properties of air and its moisture content. It involves the measurement and analysis of parameters such as temperature, humidity, pressure, and enthalpy to determine the state of air and its ability to hold moisture. These parameters are crucial for designing air conditioning systems that can maintain optimal indoor conditions for human comfort, equipment operation, and various industrial processes. This book aims to provide a comprehensive understanding of psychrometrics and its practical applications in HVAC systems. It explores the fundamental concepts and equations related to air properties, psychrometric charts, and the psychrometric processes involved in air conditioning. Moreover, it delves into the various components and systems that make up an air conditioning system, such as air handlers, cooling coils, refrigeration cycles, and ventilation systems. Optimizing air conditioning systems is a key focus of this book. By leveraging the principles of psychrometrics, engineers and technicians can enhance the efficiency and performance of HVAC systems, resulting in energy savings, improved indoor air quality, and increased occupant comfort. The book covers topics such as load calculations, equipment selection, airflow distribution, humidity control strategies, and system optimization techniques. Throughout the book, real-world examples, case studies, and practical tips are provided to illustrate the application of psychrometrics in different scenarios. Whether you are a HVAC professional, engineer, technician, or someone interested in understanding the inner workings of air conditioning systems, this book serves as a valuable resource to enhance your knowledge and skills. It is worth noting that while this book provides a comprehensive overview of psychrometrics and air conditioning systems, it does not delve into the intricacies of HVAC design and installation. For detailed design guidelines and standards, it is recommended to refer to relevant industry codes, manuals, and regulations. With a solid understanding of psychrometrics and its role in air conditioning systems, readers will be equipped with the knowledge necessary to design, optimize, and maintain efficient HVAC systems, creating comfortable and healthy indoor environments for all. Let us embark on this journey into the fascinating world of HVAC psychrometrics and unlock the secrets of optimizing air conditioning systems.

Available in PDF, EPUB and Kindle. Book excerpt: All You Ever Wanted to Know About Air… And Then Some! A/C technicians should be knowledgeable about air and its properties. This program helps technicians understand the basic properties of air and how these properties relate to each other. Over the years, much has been written on the subject of Psychrometrics. However, much of this material has been geared toward engineering and system design. Psychrometrics Without Tears presents the important concepts of air in a manner that will appeal to HVAC students and service technicians. Knowing all there is to know about an air sample is pretty empowering, so this book starts by discussing the basic properties of air and how these properties relate to each other. The Psychrometric chart is introduced to provide a visual representation of how air behaves when exposed to different conditions. Once the basics of the chart are covered, we then move into some more interesting topics such as sensible heat ratio, bypass factor, and apparatus dew point temperatures. These properties help determine system performance and are very important concepts to learn in order to fully understand air. The plotting of actual systems follows next. This involves plotting out air distribution systems that are operating correctly so that we can see what properly operating systems look like on the chart. This book covers a wide range of systems that includes residential heating and cooling systems as well as commercial systems that provide ventilation air to the occupied space to meet building code requirements. Prepare to learn about mixed air systems and learn to calculate the mixed air conditions provided we know what the outside air and return air conditions are. In addition to everything mentioned already, we will discuss the concepts of ventilation, economizing and air balancing

Download or read book Modeling and Control in Air conditioning Systems written by Ye Yao and published by Springer. This book was released on 2016-10-01 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates the latest modeling and control technologies in the context of air-conditioning systems. Firstly, it introduces the state-space method for developing dynamic models of all components in a central air-conditioning system. The models are primarily nonlinear and based on the fundamental principle of energy and mass conservation, and are transformed into state-space form through linearization. The book goes on to describe and discuss the state-space models with the help of graph theory and the structure-matrix theory. Subsequently, virtual sensor calibration and virtual sensing methods (which are very useful for real system control) are illustrated together with a case study. Model-based predictive control and state-space feedback control are applied to air-conditioning systems to yield better local control, while the air-side synergic control scheme and a global optimization strategy based on the decomposition-coordination method are developed so as to achieve energy conservation in the central air-conditioning system. Lastly, control strategies for VAV systems including total air volume control and trim & response static pressure control are investigated in practice.
