Alternative Air Conditioning Technologies: Underfloor Air Distribution (UFAD): Technology Focus
Introduction and Background Recent trends in today’s office environment make it increasingly more difficult for conventional centralized HVAC systems to satisfy the environmental preferences of individual office workers using the standardized approach of providing a single uniform thermal and ventilation environment. Since its original introduction in West Germany during the 1950s, the open pla...
متن کاملIndoor air quality analysis based on Hadoop
The air of the office environment is our research object. The data of temperature, humidity, concentrations of carbon dioxide, carbon monoxide and ammonia are collected peer one to eight seconds by the sensor monitoring system. And all the data are stored in the Hbase database of Hadoop platform. With the help of HBase feature of column-oriented store and versioned (automatically add the time c...

15 صفحه اولNumerical Simulation in the Air-Curtain Installed Subway Tunnel for the Indoor Air Quality
The Platform Screen Doors improve Indoor Air Quality (IAQ) in the subway station; however, and the air quality is degraded in the subway tunnel. CO2 concentration and indoor particulate matter value are high in the tunnel. The IAQ level in subway tunnel degrades by increasing the train movements. Air-curtain installation reduces dusts, particles and moving toxic smokes and permits traffic by ge...
متن کاملIndoor Air Quality
The issues of indoor air quality are complex and can be directly influenced by a number of system and building parameters. There are no universal solutions for every problem since there are numerous potential contaminant sources. They may originate from indoors and have a direct impact on indoor environmental quality, or they may originate from outdoors and be transferred by a mechanical or nat...
