Abstract

本論文では,電力と熱を同時に生成する太陽エネルギー利用ハイブリッドコレクタの導入効果を検討することを目的として,発電,集熱特性の実験と解析を行った.まず,熱媒送り温度を一定とした実験を行い,変換効率は10〜13%,集熱効率は20℃の低温集熱において40〜50%,実際の利用温度に近い40℃において20%程度となることを示した.次いで,発電,集熱それぞれの単体方式との比較を行った.その結果,集熱効率は若干の低下が見られるものの,エクセルギー効率の観点からは,ハイブリッドコレクタが最も有利となることを明らかにした.さらに,実験用戸建て住宅において,年間にわたる実規模実験を行い,省エネルギー効果の高いことを確認した.

This paper describes the effectiveness of a hybrid solar collector which generates both electric power and heat. Experiments and analyses on characteristics of power and heat generation through the hybrid solar collector were carried out. Firstly, experiments under the condition of constant supply temperature of brine were made and it was found that collector efficiency on electric power was from 10 to 13%, and that its efficiency on heat at 20℃-brine temperature and 40℃ was from 40 to 50% and approximately 20%, respectively. Secondly, the efficiency of the hybrid solar collector was compared with a photovoltaic and a solar collector and it was clarified that the hybrid collector had an advantage from the viewpoint of the exergy efficiency, though there are some lowering on heat collection efficiency. As a result of evaluation on annual energy balance of hybrid solar collectors installed for a low energy house in Hokkaido University, it was proven that the feasibility of the hybrid solar collectors was high.
