雙迴路儲置式太陽能熱水器開發
The development of a double loop heat pipe solar heater
摘要
本研究主要在開發一套可架設於陽台之雙迴路熱管儲置式太陽能熱水器，並針對其儲熱性能進行實驗測試。雙迴路熱管儲置式太陽能熱水器外型方正，可與建築物陽台整合，不僅有效節省安裝空間，亦可達到建築美觀之功能。主要以實驗方法進行，實驗變數為改變填充量以及在儲能槽內添加隔板、傾斜熱水器探討其儲能效率。 為利用上述結果進行儲置式太陽能熱水器性能測試及改良。實驗系統採用迴路熱管，工作流體則為純水，加熱2小時後實驗結果雙迴路儲置式太陽能熱水器熱管工作流體填充量為40％時效率最高。在儲能槽內加裝隔板可改善儲能槽內自然對流，本實驗將測試在相同加熱條件下，儲能槽內有無加隔板其儲能物質溫度分層以及儲熱效率的變化。熱水器傾斜角與陽光輻射熱量有關，集熱板傾斜對於陽光輻射量會提高，但熱水器傾斜會讓熱管內工作流體液面改變，使熱水器儲能效率降低，因此本實驗的目的將測試熱水器垂直擺放於地面與傾斜15°角時儲熱效率的差異。

The purpose of this study is development a double loop heat pipe solar heater which can be set up in the balcony. For experimental to test the thermal storage performance. Experimental variables are changing the volume filling in heat pipe, adding a partition in the storage tank and inclining the solar heater to explore energy efficiency. In order to use the variables to test and improvement the solar water heater, the working fluid is pure water. Heating for 2 hours, the heat pipe filling with 40% will have the highest thermal efficiency. Adding a partition in the storage tank will to improve natural convection. Inclines the solar heater will change the working fluid surface in the heat pipe. It makes the solar heater reduce saving energy.
