Microcircuitry và giám sát từ xa Với sự ra đời của microcircuitry, định vị GIS, và Internet, chương này thảo luận về các tùy chọn theo dõi mới có sẵn. Các giao thức này đặc biệt quan trọng trong việc theo dõi các trang web từ xa cho khắc phục hậu quả hoặc sự phù hợp quá trình và an toàn (giới hạn nổ và xác định giới hạn chất hóa học độc hại). 9,1 GIÁM SÁT IAQ LIÊN TỤC TRONG CÁC TOÀ NHÀ giám sát IAQ liên tục cho các chuyên gia IAQ và quản lý cơ sở để tìm. | CHAPTER 9 Microcircuitry and Remote Monitoring With the advent of microcircuitry GIS locators and the Internet this chapter discusses the new monitoring options available. These protocols are particularly important in monitoring remote sites for remediation or process adequacy and safety explosive limits and toxic chemical limit determinations . CONTINUOUS IAQ MONITORING IN BUILDINGS Continuous IAQ monitoring empowers IAQ professionals and facility managers to find and resolve IAQ issues quickly before they become problems or crises. Intermittent continuous IAQ monitoring supplements the qualified professional with permanently installed scientific sensors that measure record and archive the indoor air quality in a building 24 h per day 365 days per year. One of the indicators of air quality is carbon dioxide levels within the total airstream. Carbon dioxide is generated through respiratory exhalation and incomplete combustion of fuels. Continuous monitoring systems often use infrared beams to detect carbon monoxide fluctuations see Figure on page 13 . Continous IAQ monitoring Creates an early warning system for targeting and correcting IAQ issues Shows precisely when complaints disappear while demonstrating when most building occupants are comfortable Assures through operational linkage proper equipment operation and maintenance even on remote sites Provides building owners and operators with ongoing proof of acceptable indoor air quality Yields a continuous historical record of contaminant levels The early warning capability when it is combined with multiple small unobtrusive monitoring devices makes monitoring in sensitive areas possible. Using remote sensors monitoring is possible within laboratories hospitals vehicle shops paint booths hazardous waste storage bunkers and vehicular housings. In the event that the sensors detect a problem IAQ professionals can be summoned to assess the immediate situation. 2001 CRC Press LLC Sensors can be configured to .
