dc.description.abstract | 近年來,溫室氣體的排放、能源短缺的危機,使再生能源倍受重視,其中淺層溫能被視為能降低溫室氣體及達成節淨綠能的有效方法。淺層溫能是涵蓋於地表10到300米之間的低溫能源,終年不易受外界溫度影響,可以視為相當穩定的熱源或熱窟。在國外利用地埋管熱交換器對地表淺層做熱的攫取已經行之有年,技術也相當純熟。另外,台灣本島土壤富含水分,具有先天發展淺層溫能的潛力;但是目前在台灣尚未見其應用,因此本研究會注重於淺層溫能中常使用的地埋管熱交換器。
本研究使用之地埋管熱交換器為垂直式的多U型地埋管熱交換器(MUBHEs),其為PVC材質管組成,整體結構與殼管式熱交換器極為相似。因此,參考傳統熱交換器理論模型中的Kern method,以Res為基礎之ho經驗方程式,並透過實驗回歸出修正後的ho=30.127Res0.2196。然而在本實驗中,當抽水泵水量32.8 LPM時,能帶走系統13.2%的散熱量,若與不抽水比較時,進而可以推估節省系統初置鑽井深度約14.9%,然若要替代一台冷卻能力約為45 kW之冷卻水塔,在相同設計條件下,至少需要3組MUBHEs才夠冷卻負載。 | zh_TW |
dc.description.abstract | In recent years, greenhouse gas emissions and energy shortage crisis have caused renewable energy in much attention and one of among shallow geothermal energy is regarded as an effective method that can reduce greenhouse gases and therefore saving and cleaning green energy can be reached. Shallow geothermal energy is situated at the surface of the earth in 10 to 300 m range of low temperature energy. It cannot be influenced by the outside temperature and is considered as quite steady heat source or heat sink. In abroad, people have been used to grab heat from the surface of the earth by borehole heat exchanger for many years, the technology of which, therefore, is highly skilled. In addition, Taiwan has the advantage of developing shallow geothermal energy because of the soil rich in moisture, but currently there is only few application of shallow geothermal energy in Taiwan, so this research was focus on borehole heat exchanger in shallow geothermal energy.
The study used Multi-U type Borehole Heat Exchangers (MUBHEs) that is made of PVC material tubes and the structure is almost similar to shell-tube heat exchangers. So, the study referred to Kern method of transitional heat exchanger theory model in which ho empirical equation is based on Res , and the correlation between ho and Res through experimental regression, ho = 30.127Res0.2196. Additionally, in an experiment, when the flow of Pump was 32.8 LPM, 13.2% heat dissipation was taken away from systems . If 32.8 LPM of flow of pump compared to no pumping, then saving initial drilling depth of system by 14.9 % was estimated. If using MUBHEs instead of cooling tower with 45 kW of cooling capacity in the same conditions, then at least 3 groups of MUBHEs were needed to cool the load. | en |
