Outline of Final Research Achievements |
The purpose of this study was to develop a new desiccant air conditioning system that is expected to contribute to energy conservation in air conditioning. It is characterized by the use of the conductive polymer PEDOT:PSS as a desiccant medium, and its reactivation is done by energization. The following objectives and issues were set to explore the possibility of a system that does not use hot air and is more efficient and controllable than conventional systems. Objective 1: Development of a desiccant element using PEDOT:PSS, and Objective 2: Development of a desiccant rotor regeneration method using conductivity. Subject 1: Development of a desiccant rotor with excellent absorption and desorption performance, Subject 2: Development of an optimal reactivation method using electric current, Subject 3: Investigation of desiccant element shape through experiments and numerical analysis, Subject 4: Investigation of operation method through experiments using an experiment and analysis.

Academic Significance and Societal Importance of the Research Achievements |
高温多湿地域の発展と人口増に伴う冷房需要の増加で,空間の冷却に要するエネルギーの大幅な増加が予想されている。また温暖化による温度上昇のインパクトも大きい。冷房は冷却と除湿を行うが,湿度処理は低温を必要とし,これが冷房効率化の妨げになる。また,室内の湿度は人が発生する水蒸気と人の為の換気が主因で今後も減少しないが,省エネの進展で冷却の対象となる熱は減少する為,相対的に湿度処理のエネルギーは増加する。湿度を処理するためにデシカント空調が期待されるが,経済性や装置の大きさ等を理由にあまり普及していない。そこで本研究は通電再生型の実現で最も簡便で普及し易いデシカント空調の実現に寄与することを目指した。
