摘要

船體之塗裝塗層為保護船隻不受海水侵蝕的重要技術之一，為了防止塗料在施工過程中因環境溫、濕度的影響而變質，因此使用除濕轉輪可控制造船過程中的濕、濕度變化，防止船體結露等影響。而使用除濕空調系統又佔了廠房大部份的耗能，因此具有相當的節能潛力。本文利用轉輪式除濕空調系統，針對船體塗裝廠房，藉由改變室內設計溫濕度參數進行耗能分析，進行轉輪式除濕系統結合熱泵系統使用的節能最佳化策略，針對此複合式系統進行耗能之評估。
研究結果顯示，轉輪式除濕空調系統每調升室內設定溫度上限1℃，約可減少4~5%耗能，每調降室內設定溫度下限1℃耗能約減少了0.1~0.2%耗能，而每調升室內設定相對濕度上限5%，則約可減少7~10%耗能。接著配合PMV值範圍落在-1.8~1.8之間，是室內塗裝人員較可接受的範圍。最後挑選出以RH=80%, TH=28℃, TL=20的操作範圍最為理想，其與塗裝廠房原始控制相比節省的效益達到17%，進一步結合熱泵系統，更可節省總耗能達25.4%。

Coating hull is one of the important technologies for protecting ship from sea erosion. In order to prevent the deterioration from environmental condition, such as temperature and humidity in the process of painting, we use desiccant wheel which could control temperature and humidity efficiently to prevent condensation and other effects of hull in shipbuilding process. Further, Dehumidification System is accounted for most of the energy of plant, so it has a huge potential for saving energy. By changing the temperature and humidity parameters of interior design, Rotary Dehumidification System is used in this paper to analysis energy consumption for hull coating plant. At the same time, we evaluate energy consumption of combination of heat pump system and hybrid system.
According to the result, whenever 1℃ temperature limit(TH) is increased in interior design of Rotary Dehumidification System, 4~5% energy consumption can be saved; whenever 1℃ temperature limit(TL) is decreased, 0.1~0.2% energy consumption can be saved; Moreover, whenever 5% relative humidity limit(RH) is increased, 7~10% energy consumption can be saved. Also, the PMV range which fells between -1.8 and 1.8 is the most acceptable range for indoor coating staff. Lastly, we conclude RH=80%, TH=28℃, TL=20 is the most ideal range for all energy saving strategy. Compared with the original control of coating plant, we can save 17% energy consumption. Furthermore, if we combine this system with heat pump system, we can save 25.4% energy consumption in total.
