HVAC Control in the New Millennium.pdf - HVAC.Amickracing

PrefaceBuilding conditioning is changing rapidly as we enter the newmillennium. Advances in personal computer control and sensortechnology will lead the advances in building controls. Some ofthese techniques are just emerging in major industrial automaionprojects. Pushing the technology along are potentially high reductionsin operating costs from the increased efficiency of operation.PC-based control, Internet/Intranet and other computer technologieswill bring many changes and challenges to those involved in HVACsystems automation.This book investigates how the latest advances in distributed technologywill be used in commercial systems. It analyzes the impact of thistechnology on HVAC control strategies and operator interfaces includingfuture concepts of human/machine interfaces. The potential benefitsof improved technology mean additional energy and cost savings.Based on recent and upcoming standards HVAC control strategymay evolve with changing needs linked to plant-wide enterprise systems.These distributed HVAC systems provide the wide area technologyneeded for HVAC system remote access and Internet work communications.There are major improvements to be gained by intelligent fielddevices along with increased system integration. Smarter systems willuse extracted data to build databases and provide automatic piping,electrical and instrumentations drawing on-line, even via remote terminalson the Internet.Advances in microtechnology will provide economic and environmentaladvantages for space heating. The air in a room may be heatedand cooled more efficiently using small channels of micro heat pumps.Real-time environmental sensors will monitor workplace air quality andminimize lost work hours due to sick-building syndrome.Embedded Web technology and improved real-time operating systemswill operate via the Internet or plant-wide Intranets. Benefits fromthis technology include improved worldwide remote diagnostics of systemand equipment failure with real-time monitoring of control systems.©2001 by The Fairmont Press, Inc.
