The water two-phase change is used for energy conversion, and the average air flow rate of the invention can be completely isolated as long as 0.2 m/sec, which can save 6RT freezing capacity equivalent to 6KW energy consumption compared with the conventional smoke exhausting cabinet body, effectively interacting with the outside world. Space isolation to avoid leakage of high pollution toxic gases in the cabinet.

本發明主要裝置於實驗排煙櫃體內，利用進排氣能量轉換裝置，將外氣引入能量轉換裝置中，利用水二相變化進行能量轉換，將進氣降溫(夏天)或加熱(冬天)後經輔助風扇與氣門之結構，於櫃體活動門上，由上向下吹出形成一隔離氣幕，進氣平均流速只要0.2m/sec，即能有效將排煙櫃體與外界空間隔離確保櫃體內之高污染有毒氣體漏於實驗室內，確保人員安全，並徹底解決實驗室因櫃體排氣形成負壓造成空調能耗嚴重損失。
1.雙重氣幕隔離有效阻絕有毒氣體洩漏，確保操作人員安全。
2.雙重氣幕隔離櫃體開口空氣流速僅需維持0.2m/sec。即能徹底防止高污染有毒氣體外露。
3.利用經能量回收外氣形成隔離氣櫃有毒氣體。完全隔絕室內空氣的抽離效應，節省習式空調能量75％。
4.利用水二相變化進行能量轉換，能量轉換效率最低達100%以上。排氣不造成空調能量嚴重損失。
5.徹底穩定環境溫度，確保櫃體內實驗品質。
6. 本發明可與物聯網結合，符合未來智慧電網的發展趨勢。

1. Energy conversion using two-phase changes in water.
