碩士 === 國立臺北科技大學 === 能源與冷凍空調工程系碩士班 === 99 === In 2010 Taiwan Power Company reported that the total electricity consumption for industrial sectors accounts for 134.13 billion kWh, 69% out of the total electricity 193.31 billion kWh.With the concept of environmental sustainability, building a new power plant seems an impractical solution to meet the current increasing electricity demands. Also, it is impossible to invent a new power generation system in short time. Energy saving approach is a good, applicable solution to resolve the crisis.In the past, many cleanrooms in high-tech fabs were built with the over designed, energy-intensive supply air systems, which have been identified for energy saving potential today.Generally, makeup air unit is used to treat the various outdoor air conditions throughout the year.The general building energy simulation softwares are not able to handle such complicate systems. This study developed a computational application program to analysis the annual outdoor air conditions, and to compute the total annual energy consumption and carbon dioxide emissions for high-tech fabs.This study discusses three different HVAC system designs, which includes air handling unit supply air system, dispersion supply air system and air-washer make-up air unit supply air system.The results show that the air-washer r make-up air unit supply air system is the least energy-intensive and achieves the lowest carbon dioxide emissions.
