This second edition of the guide, now in SI units, highlights the acoustical features of a wide range of HVAC system components along with many noise and vibration control products, and offers strategies for selecting equipment and designing systems. Based on comments from readers of the first edition, the guide has been reorganized for easier use and includes more charts, tables, and photographs. The original publication was made possible by funds from ASHRAE research.
"Provides engineers and other design professionals with the tools and knowledge to design duct systems so that fans are properly sized, minimize the installed cost of the ductwork, minimize system-generated noise, and minimize the fan energy consumption of commercial and industrial duct systems"--
This book was written specifically for boiler plan operators and supervisors who want to learn how to lower plant operating costs, as well as how to operate plants of all types and sizes more wisely. It is newly revised with guidelines for HRSGs, combined cycle systems, and environmental effects of boiler operation. Also included is a new chapter on refrigeration systems that addresses the environmental effects of inadvertent and intentional discharges of refrigerants. Going beyond the basics of "keeping the pressure up," the author explains in clear terms how to set effective priorities to ensure optimal plant operation, including ensuring safety and continuity of operations, preventing damage, managing environmental impact, training replacement plant operators, logging and preserving historical data, and operating the plant economically.
"This text covers the need for HVAC controls, the basics of electricity, control valves and dampers, sensors and auxiliary devices, self- and system-powered controls, electric controls, pneumatic controls, analog electronic controls, diagrams and sequences, DDC hardware and software, DDC networks and control protocols, and digital control specification"--
