在再生能源議題聲浪不減的時代,能源供應方式的移轉並非一蹴 可幾,存在於再生能源設備與傳統石化能源設備間的節能設備扮演關鍵性之重要角色。本研究冷熱電聯產系統即為此類設備之典型代表。 本研究採用JetCat公司SPT5微型渦輪引擎進行發電配置與廢熱 利用設計,該發電系統經一改良動作,透過實驗量測與系統參數見立,發現其發電效率可達10.65%。然而渦輪發電系統具有近1000K之高溫廢熱能量,因此,本研究藉由程式設計一吸收式冷凍系統進行其廢熱致冷作用,分析吸收式冷凍系統各項參數影響,並調配適用於SPT5微型渦輪發電系統之冷凍系統規格,探討其發電能量、致冷能量與加熱能量多寡,並著重於總體效率提升程度,完成一套結合微型渦輪發電系統與吸收式冷凍空調之冷熱電聯產分析研究系統。最後,再評估此研究之冷熱電聯產系統應用於多種環境之可能性。 由研究歸納得知,引入廢熱利用概念可提升微型渦輪發電系統總 體效率約4倍,其全負載致冷能力可達56.23 kW,配合其發電量14.4 kW,可供應一小型社區於尖峰時段所需之能量;亦分析出其多種使用環境之建議能量分配。以上資料可提供後者於冷、熱、電共生系統研究方向及市場效益評估方式之參考依據。
To pursue renewable energy, it is hard to find new energy sources in our daily life. It should be easier to find alternative ways to improve our current energy technology to increase efficiency and reduce waste. Therefore, Combine Cooling Heating and Power Systems (CCHP) are one way to do this for us. . In this study, we used a microturbine SPT5 model made by JETCAT as the main power source for our CCHP system. The microturbine has attained a thermal to electric efficiency 10.65% with about 1000K exhaust gas temperature. An Absorption Refrigeration System (ARS) was designed to create the cooling capacity by using the waste heat. Then we analyze the Coefficient of Performance (COP) and temperatures in the ARS system. By estimating how much cooling and heating load are needed from CCHP, we can perform a study of the configuration design and performance analysis for CCHP. Finally, the feasibility of CCHP systems for different scenarios would be analyzed. . In conclusion, by using the concept of waste heat recovery, the overall efficiency of the original system can be greatly improved. The cooling load of 56.23 kW and electricity load of 14.4 kW in our CCHP can support a small community. The methods and databases in this study can provide guidance to help future CCHP system designs.
