臺灣博碩士論文加值系統

本文主要目的是利用熱板優越的熱傳特性，將其應用於儲能系統上，使得熱能獲得有效之利用，並針對此系統於儲能過程中之熱傳特性做一分析。

在實驗分析方面，首先針對熱板模組做穩態熱交換性能分析，接著將以動態分析的方式來測試其儲能特性。此外，將以三氧化二鋁做為建材與水混合之儲能材料，針對其做儲熱能的性能影響。

綜整量測結果，本文所建構之熱板模組做為熱交換器時，當水流量為0.5 kg/min，改變入口的水溫時，熱板模組系統總熱傳係數呈現一定值，約為0.9 W/m2 ℃。水溫每增加5℃，可增加20%之熱傳量。熱板模組系統總熱傳係數與水流量有著線性的關係，當水質量流率每增加0.5 kg/min，總熱傳係數值約可增加15-20%。

儲能與釋能過程中，於實驗條件下，水質量流率0.5 kg/min，熱板模組總熱傳係數呈現一定值，約為1.1 W/m2 ℃。

三氧化二鋁與水之最佳混合比例為5:4，於本實驗中可知，約可提升系統6%之儲能量。

The heat plate was utilized to solve the problems involving heat transfer due to its superior heat transfer characteristics. The purpose of this thesis is to study the thermal performance of the energy storage system which utilizes heat plate module as heat transfer mechanism. Besides analyze the influence of heat charge by using alumina dioxide combines with water as energy storage material.
According to the conclusions of this thesis, the overall heat transfer coefficient, which using heat plate module as heat exchanger, is 0.9 W/m2 ℃ when mass flow rate of water is 0.5 kg/min and that of air is 0.668 m3/min. This value is independent with the inlet temperature of heat plate module, but there exists a linear relationship between the overall heat transfer coefficient and the mass flow rate of water; the overall heat transfer coefficient, which using heat plate module in energy system, is 1.1 W/m2 ℃ when mass flow rate of water is 0.5 kg/min. This value is constant whether in heat charge and heat discharge process.
Furthermore, the experimental result shows the optimal mixture portion of alumina dioxide combines with water is 5:4, It also found that the mixture energy storage material arises the heat storage quantity of heat storage system with 6%.
