摘要

臺灣是個島型區域，能源供應主要依靠進口。在發電結構中77%由火力發電提供，大量的媒、天然氣及燃油被消耗，產生更多的二氧化碳推升地球溫度，也伴隨著大量的PM 2.5懸浮物生成，造成空氣品質惡化。
工業用戶為用電結構中主要使用者，消耗了所有發電量的60%。在工廠用電中，廠務設備佔全廠用量的40%~50%，而空調設備耗電量為廠務系統最大使用者，其次則是空壓機設備。
工廠在制定節能方案時通常是以消耗能量順序、所需金額及回收年限為主要判斷條件。通常不需要花費金錢的項目優先執行。因此契約容量及功率因數應最先被檢討，接著是提升環境溫度、調整冰機及其輔機系統的設定，使系統不做多餘的耗功。當這些不需花錢的工作完成後，才會考慮進行需費用的節能改善。在決定要花錢改善設備時，回收年限通常是考慮的最主要因素。回收年限通常會訂在5年，因為5年過去，設備會開始老化，維修保養費用會增加。
在能源仰賴進口的台灣，隨著每年台電的用電裕度不斷減少，節約用電變成一件急迫且必須的工作，本論文所提出的節能方向，都是實際驗證過，一般工廠皆可使用的節能措施，至於特殊種類的行業，會因環境條件不同，而著重不同的節能手段。

Taiwan is an island-based regional. Its energy supply is mainly dependent on imports. For the power generation structure, 77% is provided by thermal power generation. A lot of coal, natural gas and fuel are consumed. More carbon dioxide are produced to cause the increment of earth temperature. A large number of PM 2.5 suspended solids are also accompanied. The air quality is deterioration.
Industrial users are the main users, which consumed 80% of all generating capacity of the electricity structure. In the factory, the electricity use of plant equipment is accounted for 40% to 50% of the total power consumption. Air conditioning equipment is the number one power consumption user for the plant system, then the air compressor equipment.
Factories in the development of energy-saving strategy, the energy consumption order, the cost and the recovery period are the main judgment conditions. Projects that do not need to spend money are always listed of priority implementation. Therefore, the contract capacity and the power factor correction are first reviewed. Then to raise the ambient temperature by adjusting the chiller and its auxiliary system settings to avoid that the system do unnecessary power consumptions is the second choice. After these options that do not need to spend money are implemented, the measures of energy-saving improvement will be considered.
The most important factor in considering to spend money on improving equipment the recovery period is usually considered. Recovery period is usually set for five years. Because the equipment will begin aging after used 5 years, the maintenance costs will be increased.
For Taiwan, the energy depends on import. With the annual electricity margin continuing to decrease, energy-saving is an urgent work. The energy-saving measures proposed in this report are practically used and are actually verified of the general factory. As for the special types of industries, due to the different environmental conditions, different means of energy conservation will be focused on.
