台灣位於高溫高濕的亞熱帶環境，除濕與乾燥系統對於民生與半導體工業而言非常重要，且未來新興市場如越南、印尼、印度與南美洲，都為高溫高濕的環境，因此開發節能除濕乾燥設備是未來空調界的發展重點，液態除濕系統因為同時具有節能除濕與殺菌的功能，在2050淨零碳排與COVID-19後疫情時代有著極大的優勢，傳統的氯化鋰水溶液吸收劑因為具有金屬腐蝕與結晶的問題，且再生溫度偏高，應用受限，新型離子液體因為不具金屬腐蝕性且不會結晶，具有很大的應用潛力，透過實驗證明，離子液體可以在45℃再生條件下具有良好的除濕效果，且可透過市售活性碳濾網，使出口達到0 ppb，未來使用工業廢熱驅動，並應用於半導體恆溫恆濕空調將具有很高的潛力。

Taiwan locates in a hot and humid environment. Dehumidification and drying systems are important for the domestic and semiconductor industry. Emerging markets such as Vietnam, Indonesia, India, and South America are located in the same environment. Therefore, the development of energy-saving dehumidification systems is the key development trend of the air conditioning industry in the future. Because the liquid dehumidification system has the functions of energy-saving dehumidification and sterilization at the same time, it has great advantages in the 2050 net zero carbon emissions era and the post-COVID-19 epidemic era. The traditional lithium chloride solution has metal corrosion and crystallization problems, and the regeneration temperature is too high, so the application is limited. The novel ionic liquid has great application potential because it is not corrosive to metal and will not crystallize. Experiments have proved that the ionic liquid can be regenerated at 45°C. It has a good dehumidification effect and can pass through commercially available activated carbon filters to make the outlet reach 0 ppb. It has a high potential for being driven by industrial waste heat and applied to semiconductor constant temperature and humidity air conditioners.
