Description Back to topThis book presents engineers with solutions to the problems found in control applications in the commercial HVAC buildings industry. Using their experience to take readers beyond textbook principles, the authors offer suggestions for troubleshooting not found in any other book. Divided into two sections, HVAC Controls and Systems covers all aspects of commercial controls, including pneumatic, electric, and electronic controls. The first section discusses the hardware of the controls industry: thermostats and humidistats, dampers and damper motors, automatic valves, transmitters, auxiliary devices, construction systems and devices, and electronic products. The second section covers applications of the hardware for air handling unit systems, terminal systems and units, primary systems, heat pump cycles, distribution systems, supervisory systems, maintenance and operations, and total facility approach. Back Cover Back to topProfessional tips and techniques help you pinpoint and solve all kind sof problems in commercial control systems. Covering all facets of commercial HVAC control systems, including pneumatic, electric, and electronic control systems, including pneumatic, electric, and electornic controls, this guide is filled with practical solutions to help you isolate and solve virtually any kind of equipment problem. Based on the authors 35 ears of experience in the field, the guide gives you information not found in any other book about the hardware of HVAC controls as well as systems applications for the hardware. Key features include: State-of-the-art coverage of supervisory controsl and systems; troubleshooting tips for adjusting and retrofitting HVAC equipment to meet current regulatory and economic needs; pointers on the proper use of automatic dampers, transmitters, auxiliary devices, and more; detailed coverage of the different types of both electric and electronic controls. Youll find solutions to all types of problelms in commercial HVAC control systems for immediate, on-the-job help in isolating and attacking trouble spots in specific hardware products or in the entire system.
