臺灣博碩士論文加值系統

冷樑系統(Chilled Beam)盛行於歐洲及澳洲，具有節能、舒適度佳、風速慢、溫度分佈均勻、保養方便等優點，但因台灣屬亞熱帶濕熱環境，相較於其他乾燥氣候區，更需注意冷樑空調系統結露之問題。因此，本研究藉由實驗方法，探討相關設計參數及環境條件對於冷樑空調系統之結露影響，以提供該系統之結露預防及控制的相關設計與運轉參考，確保系統之可靠性。
本研究為探討冷卻樑板產生結露影響最大之因子，利用田口方法實驗，挑選4因子4水準並選擇L16直交表，因子分別為冷樑冰水盤管表面溫度(18℃、19℃、20℃、21℃)、外氣滲透風的路徑(高進低出、高進高出、低進高出、低進低出)、外氣滲透風量(20CMH、40 CMH、60 CMH、80 CMH)及外氣滲透風的露點溫度條件(18.7℃、21.3℃、22.9℃、24.2℃)進行實驗測試。並且利用S/N比反應表，分析各因子不同的水準對系統的反應大小。
研究結果顯示冰水溫度對於冷樑盤管的結露影響很大，其次為外氣滲透風的露點溫度、外氣滲透風量及外氣滲透風路徑。

The Chilled Beam prevails in Europe and Australia, it is characterized by energy saving, good comfort, slow air velocity, uniform temperature distribution and convenient maintenance. However, Taiwan is located in subtropical zone, in comparison to other dry climate zones, the condensation of chilled beam air-conditioning system shall be paid more attention to. Therefore, this study experimentally discusses the effect of design parameters and environmental conditions on the condensation of chilled beam air-conditioning system, so as to provide the design and operation references for the condensation prevention and control of the system to guarantee the system reliability.
In order to discuss the factor which has the greatest effect on the condensation of chilled beam, the Taguchi experiment is used, four factors, four levels and L16 orthogonal table are selected. The factors are chilled beam chilled water coil surface temperature (18℃, 19℃, 20℃, 21℃), path of outside air infiltration (high-in low-out, high-in high-out, low-in high-out, low-in low-out), outside air infiltration capacity (20CMH, 40 CMH, 60 CMH, 80 CMH) and dew point temperature of outside air infiltration (18.7℃, 21.3℃, 22.9℃, 24.2℃) for test. The factor combination of the worst quality, i.e. highest dew-point temperature, which will cause the highest risk of condensation is found out according to the responses of different levels of various factors to the system by using S/N ratio response table.
The findings show that the chilled water coil surface temperature has great effect on the condensation of chilled beam coil, and then the dew point temperature of outside air infiltration the path and the path of outside air infiltration .
