Manufacturing Development and HVAC (Heating, Ventilation, and Air Conditioning) in South Korea

The author opened the cafe “Duct Love” in January 2003 with the question, “A national duct technical qualification is absolutely necessary!” and has since been conducting six courses, starting with the first “Duct Design Practical Training” “Beginner Course” in May 2007.
While giving lectures, he felt the need for a textbook on “Duct,” which led him to write this book.

This book is a compilation and supplementation of the contents of the 'Duct Design Practical Training' 'Beginner Course' that has been conducted for 15 years since May 20, 2007.
The author intended to enhance the educational effectiveness of this book by providing students who wish to receive practical training in duct design with a preview opportunity.
Also, since duct subcontracting must be eliminated, we have described how to get rid of duct subcontracting.


Although specialized techniques and expressions were unavoidable, as this is a compilation of an introductory course in duct design, formulas and diagrams were minimized and concepts necessary for practical use were explained in detail.

The author left this message to the readers of this book.

“To become a manufacturing powerhouse capable of sustainable development, a group of ‘HVAC experts’ must be formed to creatively upgrade and optimize the manufacturing environment and production facilities, no less than to develop manufacturers’ core technologies.
Among the approximately 580,000 domestic manufacturers, we hope that the experts in "environmental air conditioning systems," who have developed practical experience and engineering knowledge to support the manufacturing and work environments of small and medium-sized enterprises (SMEs), excluding large, high-tech corporations, will contribute to the competitiveness of SMEs.
