Since the publication of the first edition in 1992, the HVAC industry has gone through enormous changes. As simple digital systems have given way to more complex systems, demand for information on how these systems operate, how they are best applied and how they communicate with other building control systems has grown rapidly. Direct Digital Control for Building Systems, Second Edition is thoroughly updated and expanded to include coverage of the architecture of modern digital control systems, distributed intelligence networked systems, communication protocols, the technologies and issues concerning interoperability, the latest application strategies, and defensive techniques for designing and specifying control systems. Numerous illustrations throughout help keep the subject highly accessible, and hardware, software, and systems applications are described in the most universal terms possible. This thoroughly revised second edition also contains a full section on BACnet® standard and Echelon's LonWorks® technology; their meaning, applications, and future implications. An up-to-date appendix is provided. Insights on emerging technologies in intelligent control systems and what the future holds for this dynamic field is covered throughout.

Relates rigorously derived mathematical relationships for single-input DDC systems to their practical design. Deterministic and stochastic input data are considered with the objective of demonstrating the close mathematical similarities between results derived by the z- and Laplace Transformations.

Direct Digital Control For Building Hvac Systems written by COFFIN MICHAEL J. and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1992 with Commercial buildings categories.

Over two million commercial buildings in the U.S. are controlled by direct digital control (DDC) or like systems, and the trend is toward totally intelligent buildings by the end of this century. Even though DDC is quickly replacing traditional methods of controlling temperature, humidity, lighting, security, and life safety in commercial office buildings, guidance on the fundamentals, applications, and economics of DDC has been difficult to find. Applications-oriented and written from a practical point of view, Direct Digital Control for Building HVAC Systems is one of the first books to familiarize the reader with how to' specify, purchase, and support microprocessor-based building control systems. Even those with limited knowledge of digital technology will be enabled to implement DDC systems, thanks to down-to-earth descriptions of the purpose, benefits, and limitations, design, construction, operation, and cost of these systems. Especially valuable are the book's methods for interfacing digital control with existing HVAC systems. Mechanical engineers involved in the design of building control systems, mechanical estimators, facilities, plant, and building operations and maintenance personnel in both the public and private sector will all find this book a valuable resource.

The purpose of this report is to describe the state-of-the-art of direct digital control (DDC) system technology that monitors and controls mechanical and electrical systems found in Government facilities. A DDC system can operate either as a stand-alone control system or as an extension to an Energy Monitoring and Control System (EMCS). Direct digital control systems are self-contained computer based systems which monitor and control processes in accordance with predetermined strategies. This report addresses the commercial-type DDC systems, in which sensors and controls are connected to a control panel. Control devices are modulated directly by the DDC system in accordance with established algorithms. Unlike industrial-type DDC systems, commercial-type DDC systems do not have a specific address for each control point position. Additional keywords: Energy management; Installation; Acceptance tests; Maintenance.
