吸附式空調系統利用低溫熱源來驅動，不使用壓縮機，減少電力需求。其系統構造簡單，運動元件少，沒有震動與噪音的問題，工作介質為非氟氯碳化物，更減少了對環境的污染。本研究於真空狀態下量測三種吸附材，金屬有機框架MOF、FAM-Z05沸石以及矽膠等在不同溫度及壓力下之水汽吸附性能，並比較各種吸附材在不同空調運轉條件下之吸、脫附率差。結果得出，當冰水溫度20°C時，不論熱水溫度為80°C或是60°C，MOF之吸附率差皆遠高於FAM-Z05以及矽膠之吸附率差。FAM-Z05在熱水溫度為60°C時，吸附率差高於矽膠，但在熱水溫度為80°C時，兩者差異不大。另由於MOF吸附率在20°C至15°C之間急遽降低，而FAM-Z05吸附率急遽降低區間在15°C至10°C之間，因此當冰水溫度15°C，熱水溫度60°C時，FAM-Z05之吸附率差高於MOF。而矽膠吸附率並沒有明顯轉折溫度，在低冰水溫度下吸附率仍高，因此整體吸附率差皆最小，吸附性能最差。由於MOF在合成過程可藉由孔隙度之控制，調整其吸附率轉折溫度，因此在未來MOF研究中可嘗試將其轉折溫度降低至15°C至10°C之間，使可適用於較低溫之冰水製作。 |
| 英文摘要 |
The adsorption air-condition systems are driven by low-temperature heat sources but not by electrical driven compressor. They are able to reduce the electricity demand. These systems are simple construction, with less moving parts and without the problems of vibration and noise. Since their working fluids are non-chlorofluorocarbons, it can also reduce the global warming effect. This study provided the vapor adsorption performance measurements of three adsorbents, MOF, FAM-Z05 zeolite and silica gel at various temperatures and pressures. The adsorption ratio differences under various air-condition operation conditions were evaluated and compared. The test results show that while the chilled water temperature is 20 °C, the adsorption ratio differences of MOF are higher than those of FAM-Z05 and silica gel at the hot water temperature of 60 °C or 80 °C conditions. The adsorption ratio differences of FAM-Z05 are higher than those of silica gel at 60 °C hot water but are very close of these two adsorbents at 80 °C hot water condition. While the chilled water temperature is 15 °C, the adsorption ratios of MOF are decreased and lower than those of FAM-Z05 owing to there is a significant drop of adsorption ratio at evaporator temperature from 20 to 15 °C for MOF. Since the transition of adsorption ratio for MOF can be controlled by adjusting its porosity, it is suggested that to develop the MOF with transition temperature range from 15 to 10 °C in the future studies for air-condition applications. |
