摘要

相當多的國外研究已經證實負離子對人體的好處。有研究指出，提高室內的負離子濃度可增進辦公室員工的工作效率，使其有更高的警覺性和更佳的注意力、並能提振精神；為了能達到上述好處，必須使負離子濃度維持在高濃度，而在有限的室內空間中，設置一台負離子生成器乃最為容易達成的方法。本研究以實驗瞭解負離子生成器所產生之負離子於限制空間中的分佈情形。實驗中以距離為主要變因，依據負離子所存在的實驗環境的條件與特性，探討負離子的擴散與分佈之情形。實驗結果顯示在密閉空間內，未開啟空調與負離子生成器的狀況下，實驗空間內任一點的負離子濃度大致相同，而在開啟空調後，對於室內限制空間中之負離子濃度確實有所干擾。而在研究中也發現，負離子受負離子生成器的吹送距離不但有其限制，在不同方向上也有所差異。

A great number of studies have demonstrated that negative ions are good for health. Researchers have proved that workers are more efficient, alerted, good concentration, and high in spirit when the level of negative ions are high. In order to boost the concentration of negative ions, a negative ions generator is used to produce negative ions for a confined space. This research is intended to investigate how negative ions distribute in a confined space. This experiment will put major concentration on the matter of distance, although negative ions are assumed to be impacted by natural condition, characteristics and other properties. This study has come to a conclusion that negative ions are distributed in the confined area uniformly when a negative ion generator is not activated. However, the uniformity was altered after air conditioner was activated. Moreover, the negative ion distribution in a confined space is influenced heavily by the distance away from a negative ion generator.
