How does a rotary heat exchanger work?

The wheel is built up by a matrix that consists of two foils, one flat and one corugated;together, they create channels for the air to pass through. The wheel is rotated by an electricmotor and belt drive system.
In one half of the rotation, the exhaust air from the inside space flows through the matrix. ltsheat is stored in the matrix, and in the other half of the rotation, it is transferred to the freshsupply air from outside.
The size of the channel is called well height. Different well heights and diameters of thewheel give different efficiencies, pressure drops, and airflow rates.
Rotary heat exchangers that are properly constructed, installed, and maintained have almostzero transfer of particle-bound pollutants.

ロータリー/ホイールエネルギー回収熱交換器

回転エネルギー回収熱交換器には全熱式と顕熱式の2種類があります。蓄熱コアとして外気はホイールの半円を通過し、排気はホイールの別の半円を通過します。このようにして、新気と排気が交互にホイールを通過します。
冬場、ホイール蓄熱体が排気(ウェット)から熱を吸収し、外気側に移動すると気温が悪い(ウェット)ため、排気側に回生コア本体が熱量を放出(ウェット)します。エネルギー回収はこのような繰り返しサイクルによって達成され、動作原理は図に示されています。夏の冷房運転中は、このプロセスが逆になります。
ヒートホイールがフル回転すると、空気中の水分子がハニカム表面のモレキュラーシーブコーティングに吸収され、反対側に移動すると水分子間の圧力差により放出されます。

オールヒートタイプのランナーは、外気を利用して顕熱と潜熱を交換することで省エネと室内換気を実現します。夏は外気を予冷・除湿し、冬は予熱・加湿することができます。
