灣的溫泉資源豐富，發展觀光之潛力無窮，被列為政府推動挑戰2008觀光倍增計畫的主要項目之一。然而台灣的溫泉業者為了節省成本，未考慮節能及永續利用之概念，使得現今之溫泉觀光風景區多存有溫泉資源衰竭、紊亂的管線架設、不當地大量排放熱水與超抽而造成之生態改變…等問題。
經濟部水利署於民國92年6月3日立法通過之「溫泉法」是台灣溫泉資源永續經營的起步，為了提升溫泉資源的經濟效益，在地質開發條件、開發規模與管線佈置之規劃…等諸面向皆應有更詳實的調查與理論發展。
本研究延伸應用化工領域之熱交換網路原理，分別以金崙與和美溫泉區為例，對溫泉使用之多樣化需求(熱湯、冷湯與煮蛋池…等)，作引水換熱之模擬規劃，探討其在能源之節約、熱能之有效回收利用與改善廢熱排放造成的環境衝擊等方面之助益，茲分述研究結果如下：
能源之節約：經過本研究熱交換網路之規劃模擬，金崙溫泉區約有84%的加熱需求可以由熱交換的方式滿足，約有13%的冷卻需求可以由熱交換的方式滿足；和美溫泉區最多約有78%的加熱需求可以由熱交換的方式滿足，最多約有29%的冷卻需求可以由熱交換的方式滿足。
熱能之有效回收利用：本研究之模擬規劃結果，金崙溫泉區未出現廢熱回收之路徑，而和美溫泉區在操縱變因最小趨近溫度 (ΔTmin)為10℃時，出現廢熱回收路徑(第七道熱物流與第四道冷物流之熱交換)，回收量為16.8KW，達成廢熱回收利用之目標。
廢熱排放造成環境衝擊之改善：經由熱交換網路之設計規劃，每一道物流皆須降至常溫再行排放，實可有效舒緩廢熱對於環境之衝擊。
本論文為嘗試性之研究創作，初步延伸應用熱交換網路原理於溫泉資源之規劃的結果，頗具有正面效益；而由於溫泉資源之規劃深具彈性，期盼在後續研究中，能利用此一特性進一步規劃最佳之熱交換網路的合成，並加入成本計算，作可行性之分析。

Hot spring resources of Taiwan is abundant, and the Government classified it as one of the main projects planned to double the income of the tourism business in 2008. However, to save cost, the venders of hot spring in Taiwan had not considered about the energy-conservation and sustainable utilization. There are many issue arose nowadays, such as: resource depleted, disorderly pipeline erected, and excessively discharge of hot water.
Water Resources Agency promulgated Hot Spring Act on 3rd June, 2003, to enhance sustainable use of hot spring resource. However we should keep on making efforts at geological data analyzed, available development scale assayed and the layout of the pipeline erected etc. to appreciate the hot spring resources.
This study applies the principle of heat exchanger network used in the chemical field to rectify the usage of the hot spring resources by taking Jin-Lun hot spring garden and He-Mei hot spring garden as case study. Effects of thrift of the energy, the reclamation of heat and the improvement of excessively discharge of hot water are analysed.
Major results of the study are as follows :
Thrift of the energy: There is nearly 84% of heating demand and nearly 13% of cooling demand can be left out in Jin-Lun hot spring garden. And there is at most 78% of heating demand and at most 29% of cooling demand can be left out in He-Mei hot spring garden. It does work at both two cases.
The reclamation of heat : There is no effect of reclamation of heat in the Jin-Lun hot spring garden. But there is 16.8KW of reclamation of heat in He-Mei hot spring garden. It works in He-Mei area.
The improvement of excessively discharge of hot water : Depend on the heat exchanger network, each streams discharged to the nature must be dropped down the temperature to the normal atmospheric one. This way really can lower the impact to the environment in any case.
This research applies heat exchanger network used in the chemical field to another one. Nowadays we find the good effects at the extension of rectifying the usage of hot spring resource, and the good opportunity to make properly arranged. Follow-up study can make use of this characteristic and combine the cost calculation to devise the best layout of heat exchanger network.
