| Abstract: | 依經濟部能源局統計資料指出，全國屬於能源大用戶（801kW以上）的醫院計145 家，其能源使用占非製造業大用戶總能源14.9%，高居非製造業第1位。面臨醫療健保制度與健保財政緊縮下的衝擊，各項支出費用的控制是醫院生存競爭中必要的措施。在不影響醫療品質的前提下，合理的提升能源使用效率，節約能源，藉此減少醫院在整體能源費用上的支出。本研究分析我國醫院能源消耗使用量，同時收集彙整醫院在電力、空調及熱源設備等各項節約能源方法及相關資料加以分析彙編，提供日後各醫院作為節約能源管理及設計規畫之參考。並以個案醫院耗能設備進行節能評估提出改善計畫，提出具體建議改善方案共7項。1.訂定合理契約容量。2.提高冷凝水回收率。3.回收排氣廢熱預熱空氣。4.增設熱泵加熱熱水系統。5.空調冰水主機並聯使用。6.修正泵埔揚程。7.平衡區域泵浦水量。預估可節約用電707,811kWh/年，減少熱能54.2kLOE/年，節省金額267.4萬元/年，減碳量455.2公噸CO2/年，節能率8.75%。本文所提方法確具可行性，相關成果應具實務採行之參考價值。以期將醫院由能源高度耗用者反轉為環境保護者，降低醫院能源成本，達成醫院永續經營目標。
Based on the statistics information of Bureau of Energy, Ministry of Economic Affairs, There are 145 hospitals are megawatt energy users (above 801kW) in Taiwan, the energy consumption is 14.9% of megawatt energy users in nonmanufacturing industry, the highest in nonmanufacturing industry. Face with the impact of national health insurance system and the fiscal contractions, controlling of the expenditure is necessary measures for existing. In the condition of not affecting Healthcare Quality, through improving efficiency of energy use reasonably and saving energy use in order to reduce the expenditure on overall energy expenses.This study analyzes the energy consumption in hospitals in Taiwan, and collects energy saving methods and other relative information in electricity, air conditioning system, and heat equipment at the same time, to provide the reference on energy saving management and design and planning in hospitals. Based on the equipment in the hospital in this study, develop 7 improvement plans. 1. Make a reasonable capacity in contract. 2. Increase the steam condensate recovery rate. 3. Recover exhaust-gas waste heat to preheat air. 4. Add heat pump system. 5. Use chiller machines together. 6. Revise pump head. 7. Balance the capacity of regional pumps. It is estimated to reduce annual electricity consumption of 707,811 kWh, reduce annual thermal energy consumption of 54.2 kLOE, reduce annual expenditure of 2,674,000 dollars, reduce annual CO2 emissions of 455.2 tons, saving rate 8.75%. The plans in this study are practicable, and the outcomes are valuable for implementation and reference. Expect to turn hospitals from intensive energy users to environment protectors, cutting down the expenses of energy, in order to achieve sustainable operation. |
