熱泵系統應用於大型員工宿舍之節能效益分析
Energy Saving Benefit Analysis of Heat Pump System Used in Large Staff Dormitory
摘要
本研究係以聯華電子股份有限公司之新竹地區大型員工宿舍為例，對其所使用之熱水盥洗系統，由既設之電熱鍋爐熱水設備，加裝空氣源型熱泵系統之後，收集相關運轉實驗數據，分析其所產生之節能效益，以作為日後新建宿舍時之工程參考。 在此節能工程中，預定投資金額不超過300萬元，每年以回收100萬元為此節能工程之目標，也就是投資回報率ROI(Return on Investment)每年為33%。透過新設熱泵系統的相關設置檢討，本論文研究如何與既有電熱鍋爐系統匹配、熱泵型式的選定、造水及供水模式及廢冷的回收利用等，並比較不同的加熱方式、驗證循環式逐步加熱水溫的方式，有較高之COP（Coefficient of Performance）值。 最終我們收集了實際運轉一年的相關耗能數據，與前數年比較，驗證已成功達到每年減少電費用支出100萬元的目標，因此本論文之內容將對後續的相關工程有重要的參考價值。

This research presents a case study of a large employee dormitory building, located in Hsinchu of Taiwan, which belongs to United Microelectronics Corp. The dormitory building, which previously relied on electric boilers to heat water for residents’ bathing needs, recently installed an air source heat pump system to replace or improve the existing system. The present study involved collection of experimental data regarding the operation of the new system and analysis of the energy saving benefits achieved, to provide a reference for the establishment of similar energy-saving systems in the future. For this engineering case, the total investment was planned not to exceed NT$3 millions, and a target of return was set at NT$1 million per year in energy savings, i.e. the Return on Investment (ROI) was aimed at 33% per year. To achieve these goals, this research examines various issues relating to heat pump system establishment, compatibility with the existing electric boiler system, which type of heat pump system should be selected, the water generation and water delivery model, and cold air recycling, etc. In addition, two kinds of water heating methods are compared where the results show that cycling heating method has higher COP (Coefficient of Performance). After the installation and commencing, the researcher collects operation data with respect to energy saving performance over a period of one year. By comparing with the data of past several years, the results confirm that using the heat pump system has meet the target of providing at least NT$1 million a year in energy savings. Therefore the findings and discussions in this thesis will form a solid reference for the establishment of similar energy-conservation systems in dormitory buildings in the future.
