| Outline of Final Research Achievements |
The desiccant rotor continuously rotates while adsorbing and desorbing, the amount of adsorption and desorption changes from moment to moment when the rotor rotates. On the other hand, measuring the temperature and humidity distribution inside the rotating adsorbent requires wiring for the conventional sensors, which is difficult for high-precision sensors. Therefore, we planned to use IoT sensor technology to measure the temperature and humidity distribution inside the rotor by utilizing a small sensor and wireless communication device.
A small wireless sensor was used to measure the temperature and humidity inside the rotor. Firstly, a correction method for the measurement results was conducted, a rotor with a built-in sensor was made to visualize the temperature and humidity inside the rotating rotor. As a result, the temperature and humidity environments inside several types of Desiccant rotors were compared.

現在，天然材料や合成材料を問わず様々な吸着材を基材としたデシカントローターが市場投入されている．その設計には吸着等温線が用いられることが一般的である．しかし，デシカント空調システム内に収まったデシカントローターの性能を計測することは容易ではなく，除湿量の過不足やそれに伴う仕様変更の必要性などを検討することは不可能に近い．
本研究によって回転体内部の除湿再生過程を可視化することで，吸脱着過程からデシカントローターの設計方針を明らかにすることが出来る．また，回転体や狭所など，これまで計測困難であった場所のデータ計測技術を構築することで種々の建築設備内部の状況把握や改善に応用できることが期待できる．
