In the environment with high humidity causes negative influence on human's body and living condition. As the weather gets more humid, people's interest of dehumidifier for household arising recently. The cooling dehumidifier dehumidify the air by using refrigeration cycle technology which means it removes vapor by let the humid air pass through the cold surface. The amount dehumidified of refrigerating method dehumidifier affected by multiple factors. However, the refrigerating method dehumidifier for household in the market controls pass wind velocity technology to adjust the amount of dehumidification. As the pass wind velocity increases, the amount of wind increases hence the heat exchange amount increases accordingly. However, the amount of dehumidification decreases because the temperature difference between the air and vaporization decreases. Therefore, simply by increasing air velocity does not increase the amount of dehumidification. This research examined the effect of air velocity out of all variety of factors to the amount of dehumidification for refrigerating method dehumidifier.
