HVAC Control In the New Millennium
HVAC Control In the New Millennium: Building conditioning is changing rapidly as we enter the new millennium. Advances in personal computer control and sensor technology will lead the advances in building controls. Some of these techniques are just emerging in major industrial automaion projects. Pushing the technology along are potentially high reductions in operating costs from the increased efficiency of operation. PC-based control, Internet/Intranet and other computer technologies will bring many changes and challenges to those involved in HVAC systems automation. This book investigates how the latest advances in distributed technology will be used in commercial systems. It analyzes the impact of this technology on HVAC control strategies and operator interfaces including future concepts of human/machine interfaces. The potential benefits of improved technology mean additional energy and cost savings. Based on recent and upcoming standards HVAC control strategy may evolve with changing needs linked to plant-wide enterprise systems.
These distributed HVAC systems provide the wide area technology needed for HVAC system remote access and Internet work communications. There are major improvements to be gained by intelligent field devices along with increased system integration. Smarter systems will use extracted data to build databases and provide automatic piping, electrical and instrumentations drawing on-line, even via remote terminals on the Internet. Advances in microtechnology will provide economic and environmental advantages for space heating. The air in a room may be heated and cooled more efficiently using small channels of micro heat pumps. Real-time environmental sensors will monitor workplace air quality and minimize lost work hours due to sick-building syndrome. Embedded Web technology and improved real-time operating systems will operate via the Internet or plant-wide Intranets. Benefits from this technology include improved worldwide remote diagnostics of system and equipment failure with real-time monitoring of control systems.
