Description
(第1の実施形態)
第1の実施形態に係る蓄熱装置を、図1を用いて説明する。
次に、第2の実施形態に係る蓄熱装置を、図2を用いて説明する。なお、第1の実施形態と同一の構成には同一の符号を付し、重複する説明は省略する。
次に、第3の実施形態に係る蓄熱装置を、図3を用いて説明する。なお、上記実施形態と同一の構成には同一の符号を付し、重複する説明は省略する。
次に、第4の実施形態に係る蓄熱装置を、図4(a)、(b)を用いて説明する。なお、上記実施形態と同一の構成には同一の符号を付し、重複する説明は省略する。
なお、浮力の異なる浮体を3個以上連結しても、同様な効果が得られる。
本第5の実施形態では、上述した実施形態で用いられる浮体3をマンガン窒化物等の負熱膨張率を持つ物質で構成する。これにより製造上のばらつきによって大きい浮力を有する浮体3が高温側に浮上した場合には、暖められて収縮することで沈み、小さい浮力を有する浮体3が低温側に沈降した場合には、冷却されて膨張することで浮かび、その結果として浮力のばらつきが抑制され、浮体3は所望の位置で密集して整列されることになる。
Claims (5)
- 下方に低温蓄熱材、上方に高温蓄熱材が蓄えられた蓄熱材容器と、前記低温蓄熱材と高温蓄熱材の間に配置されるとともに前記低温蓄熱材の密度と高温蓄熱材の密度の中間の平均密度を持つ多数の浮体と、を有する蓄熱装置において、
前記多数の浮体を浮体収容部材内に収容し、
前記蓄熱装置は前記浮体収容部材を上下動可能に吊り下げる吊り下げ手段を有するとともに、当該浮体収容部材に重量調整用おもりを設けたことを特徴とする蓄熱装置。 - 前記浮体収容部材に温度検出手段を設け、検出温度に応じて前記吊り下げ手段により前記浮体収容部材の高さを調整することを特徴とする請求項1記載の蓄熱装置。
- 前記浮体収容部材は網状のカバー、網状の容器又はシート状のカバーであることを特徴とする請求項1又は2記載の蓄熱装置。
- 前記多数の浮体は浮力の異なる浮体からなり、当該浮力の異なる浮体を連結部材で連結したことを特徴とする請求項1乃至3いずれかに記載の蓄熱装置。
- 前記浮体に突起を設けたことを特徴とする請求項1乃至4いずれかに記載の蓄熱装置。
