Book Description
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.

Book Description
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.

Book Description
This publication has been conceived from the author’s active career in a demanding but rewarding working genre. The day to day situation where advice and clear guidance of other more experienced engineers sometimes becomes a limiting factor has been the catalyst for the production of this publication. It is trusted I will be found to guide in many of the areas of HVAC that can cause shortcomings and disappointment in successful delivery. From initials stages of employment it was found that fundamental advice and directives were in “short supply” and given by default. Study and investigative enquiries were generally found to be most beneficial. Much learnt and proven can be valuably passed on to those who take up a career with the intentions of become an accomplished and asset to a major sector of the construction industry. It is honestly hoped this publication has or will go some way to aiding both individuals and the industry as a whole.

Book Description
Whether you tune in each week to see veteran Detective Lennie Briscoe analyze clues with wild-card partner Ed Green in the fist half of the show, or to see Assistant District Attorney Jack McCoy invoke justice in the courtroom in the second half, you cannot help but get involved with the most human characters on television. With these powerful characters and socially relevant stories ripped from today's headlines, it is difficult to tell whether you are watching the evening news or one of the most intense dramas ever seen on television. Law & Order: The Unofficial Companion was written with the cooperation of the show's creator and executive producer, Dick Wolf, and features interviews with the stars, producers, and writers. It is the first-ever guide to this popular, Emmy award-winning police drama. You'll get the inside scoop on: -the past and current stars of the show-including Paul Sorvino, Jerry Orbach, Jesse L. Martin, Christopher Noth, S. Epatha Merkerson, Sam Waterston, Carey Lowell, Angie Harmon, and Michael Moriarty-and find out who was fired, who left willingly, and who remains -the show's continued problems with censorship issues and advertiser fallout -the behind-the-scenes anecdotes about cast regulars, including the fights-both verbal and physical-that have peppered the production -how Wolf was forced to increase the estrogen and decrease the testosterone on the show -the detailed history behind the creation and development of the show, and season-by-season critiques of each episode through the entire 1999 season
