HVAC Design Sourcebook summary

Understanding HVAC System Design

In HVAC Design Sourcebook by W. Larsen Angel, we are introduced to the intricate world of Heating, Ventilation, and Air Conditioning (HVAC) system design. The book begins with a detailed overview of the HVAC design process, emphasizing the importance of understanding the unique requirements of each project. It delves into the fundamental principles of HVAC systems, including load calculations, codes and standards, and coordination with other design disciplines.

Angel presents HVAC load calculations as a critical step in designing an efficient system, highlighting the significance of accurately determining the heating and cooling loads of a building. This is followed by a comprehensive exploration of the codes and standards that govern HVAC design, ensuring that the proposed systems comply with safety, environmental, and energy efficiency regulations.

Designing Central Plant Equipment and Air Systems

The book then progresses into the heart of HVAC design, focusing on the central plant equipment and air system design. Angel discusses the different types of HVAC systems, such as air-side and water-side systems, and provides detailed insights into the selection and design of equipment, including chillers, boilers, cooling towers, and air handling units.

Furthermore, HVAC Design Sourcebook covers the design of piping, valves, and specialties, emphasizing the importance of proper selection and sizing to ensure optimal system performance. The author also explores noise and vibration control, an essential aspect of HVAC design, and automatic temperature controls, highlighting the role of control systems in maintaining indoor comfort and energy efficiency.

Understanding Distribution Systems and Terminal Equipment

The book then shifts its focus to the distribution systems, discussing the design of piping and ductwork. Angel emphasizes the significance of efficient distribution systems, stressing the need to minimize pressure drop and energy loss. This section also covers terminal equipment, including diffusers, grilles, and registers, and their role in delivering conditioned air to the occupied spaces.

In addition to the technical aspects of HVAC design, HVAC Design Sourcebook also addresses the importance of clear and accurate construction drawings. The author underscores the need for detailed and well-coordinated drawings to ensure proper installation and functioning of the HVAC systems.

Practical Applications and Conclusion

Throughout the book, Angel provides practical insights and real-world examples, offering a holistic view of HVAC system design. The final chapters of HVAC Design Sourcebook focus on the practical application of the design principles discussed earlier. Angel emphasizes the importance of continuous improvement and the integration of new technologies and sustainable design practices in HVAC systems.
