The book "Design of Industrial Ventilation" by the authors Molchanov and Chetkov is an indispensable source of knowledge for all who are interested in the design and operation of ventilation systems in industrial conditions. In today's manufacturing environment, where air quality and air circulation play a key role in ensuring worker health and equipment efficiency, this publication is becoming a true guide to the complex but vital aspects of ventilation design. The authors, with many years of experience in the field of engineering and design, offer the reader a deep understanding of the principles of ventilation systems. The book covers a wide range of topics, ranging from the basics of ventilation theory to practical recommendations for the selection of equipment and the calculation of systems. Each section is riddled with clear explanations and examples, which makes the material available to both students and experienced professionals seeking to update their knowledge. "Industrial ventilation design" will be of particular interest to engineers, architects, designers and technical students studying disciplines related to HVAC (heating, ventilation and air conditioning). The book is also suitable for those working in the field of labor protection and ecology, because it touches on issues related to the impact of air quality on the health of workers and compliance with safety standards. One of the key topics raised in the book is the importance of properly designing ventilation systems to ensure a comfortable and safe working environment. The authors focus on how insufficient ventilation can lead to the accumulation of harmful substances in the air, which in turn can cause serious health problems. They offer the reader not only theoretical knowledge, but also practical tools for evaluating and optimizing ventilation systems. The style of Molchanov and Chetkov is distinguished by the clarity and logic of the presentation . They skillfully combine a scientific approach with practical examples, which makes the book not only informative, but also fascinating to read. The authors use an accessible language, which avoids overloading with technical terms and makes the material understandable to a wide audience. The book “Industrial Ventilation Design” also includes up-to-date data on modern technologies and innovations in the field of ventilation. Readers will be able to learn about new methods and equipment that can significantly improve the efficiency and economy of ventilation systems. This is especially important in the face of growing demands for ecology and sustainable development. If you are looking for literature that will help you understand the complex issues of ventilation design, this book will become your reliable assistant. It will not only expand your knowledge, but also inspire new ideas and solutions in your professional activities. Thus, “Industrial Ventilation Design” is not just a textbook, but a whole encyclopedia that will help you become a real expert in your field.
