This book presents the most current design procedures in heating, ventilation and air conditioning (HVAC), available in handbooks, like the ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) Handbook-2013 Fundamentals, in a way that is easier for students to understand. Every effort is made to explain in detail the fundamental physical principles that form the basis of the various design procedures. A novel feature of the book is the inclusion of about 15 worked examples in each chapter, carefully chosen to highlight the diverse aspects of HVAC design. The solutions for the worked examples clarify the physical principles behind the design method. In addition, there are problems at the end of each chapter for which numerical answers are provided. The book includes a series of MATLAB programs that may be used to solve realistic HVAC design problems, which in general, require extensive and repetitive calculations.

Principles of HVAC in Buildings by J. W. Mitchell and J. E. Braun provides foundational knowledge for the behavior and analysis of HVAC systems and related devices. The emphasis is on the application of engineering principles, and features a tight integration of physical descriptions with a software program that allows performance to be directly calculated, with results that provide insight into actual behavior. The examples, end-of-chapter problems, and design projects are more than exercises; they represent situations that an engineer might face in practice and are selected to illustrate the complex and integrated nature of an HVAC system or piece of equipment. Coverage of material applicable to the field is broad: a Fundamentals section on thermodynamics, fluid flow, heat transfer, and psychrometrics; types of HVAC systems and components; comfort and air quality criteria; a Loads section on weather data processing; design heating and cooling loads; an Equipment section on air and water distribution systems, heating and cooling coils, cooling towers, refrigeration equipment, and a Design and Control section on seasonal energy use, control techniques, supervisory control, the HVAC design process, and the rules of thumb often used in design. The textbook provides a foundation for students and practicing engineers to design HVAC systems for buildings. In addition, there is extensive supplemental on-line material that provides more in-depth and comprehensive treatment of equipment and component modeling and performance that is geared towards current and future equipment design engineers.

Completely revised with the latest HVAC design practices! Based on the most recent standards from ASHRAE, this Sixth Edition provides complete and up-to-date coverage of all aspects of heating, ventilation, and air conditioning. You'll find the latest load calculation procedures, indoor air quality procedures, and issues related to ozone depletion. Throughout the text, numerous worked examples clearly show you how to apply the concepts in realistic scenarios. In addition, several computer programs (several new to this edition) help you understand key concepts and allow you to simulate various scenarios, such as psychometrics and air quality, load calculations, piping system design, duct system design, and cooling coil simulation. Additionally, the load calculation program has been revised and updated. These computer programs are available at the book's website: wiley.com/college/mcquiston Key Features of the Sixth EditionAdditional new worked examples in the text and on the accompanying software.Chapters 6-9 have been extensively revised for clarity and ease of use.Chapter 8, The Cooling Load, now includes two approaches: the heat balance method, as recommended by ASHRAE, and the simpler RTS method. Both approaches include computer applications to aid in calculations.Provides complete, authoritative treatment of all aspects of HVAC, based on current ASHRAE standards.Numerous worked examples and homework problems provide realistic scenarios to apply concepts.

Heating and cooling load calculations are carried out to estimate the required capacity of heating and cooling systems, which can maintain the required conditions in the conditioned space. To estimate the required cooling or heating capacities, one has to have information regarding the design indoor and outdoor conditions, specifications of the building, specifications of the conditioned space (such as the occupancy, activity level, various appliances and equipment used etc.) and any special requirements of the particular application. For comfort applications, the required indoor conditions are fixed by the criterion of thermal comfort, while for industrial or commercial applications the required indoor conditions are fixed by the particular processes being performed or the products being stored. Generally, heating and cooling load calculations involve a systematic and stepwise procedure, which account for all the building energy flows. In practice, a variety of methods ranging from simple rules-of-thumb to complex transfer function methods are used to arrive at the building loads. This short quick book provides a procedure for preparing a manual calculation for cooling load using CLTD/CLF method suggested by ASHRAE and includes two detailed examples. For more advanced methods such as TFM, the reader should refer to ASHRAE and other handbooks.Learning ObjectiveAt the end of this course, the student should be able to: 1. Understand the basic terminology and definitions related to air conditioning load calculations 2. Explain the differences between heating and cooling load design considerations3. Explain the difference between 1) space heat gain v/s cooling load 2) space cooling v/s cooling load and 3) external loads v/s internal loads4. Differentiate between sensible and latent loads5. List commonly used methods for estimating cooling loads 6. Estimate the internal and external cooling loads using CLTD/CLF method from building specifications, design indoor and outdoor conditions, occupancy etc. 7. Describe various equations and the information sources to determine conductive load through opaque building elements.8. Describe various equations and information sources to determine the solar transmission load through glazing.9. Describe various equations and information sources to determine the internal load due to people, lights and power appliances.10. Determine the supply air flow rate11. Learn by examples the detailed methodology to cooling load calculations12. Learn the functional parameters of software programs such as TRACE 700 and CHVAC
