空氣壓縮機排熱回收應用研究
A study on the applications of heat recovery from the air compressor exhaust
摘要
本論文針對使用空壓機所產生的廢熱作熱回收，運用在外氣空調箱(MAU)，並分析及評估熱回收後供應取代或降低工業廠房之外氣空調箱在冬季需求回溫加熱及節省消耗能源的使用。主要利用地區全年逐時平均溫度與相對濕度來計算各案例所使用的外氣空調箱所需加熱量與空壓機運轉所產生的廢熱作比較，研究結果顯示空壓機無論是使用水冷或氣冷式空壓機排廢熱皆可有效回收應用，可替代現有外氣空調箱使用鍋爐產生熱水供應加熱或使用電熱加熱，且均能100%替代外氣空調箱原有加熱設備，節省原有加熱設備的能源成本。目前大量使用空壓機的工業廠房可進行空壓機系統改造，在不影響空壓系統供氣品質及穩定度下，能降低廠區不必要能源浪費，達到節能減碳的目的，也可提高空壓機整體系統的能源使用效率。

This research is primarily on the heat recovery from air compressor applications. The feasibility of the application of waste heat recovery for the reheat of the makeup air of the makeup air unit (MAU) has been studied. An annual analysis that based on the hourly weather data was used to estimate of the heating requirement of MAU. Energy efficient of heat recovery that can cover the heating need of MAU all year round was also discussed. Industrial case studies show that the waste heat recovery applications can be accomplished for either water-cooled or air-cooled air compressors. Moreover the heat recovery is sufficient to meet the heating requirement of MAU, and therefore can totally replace the operation of water boilers. The research results also show that heat recovery from air compressors has wide range of applications in the industry. Modifications of the present air compression systems to allow heat recovery are proposed in this thesis so that the air compressor system can still retain steady operation to provide normal air quality. Finally the results show that much energy cost can be saved and carbon emission can be reduced by waste heat recovery from the industrial air compressor systems.
