東京都の2つの小学校と1つの高校、旭川市の1つの高校、宮崎県の1つの小学校、東京都の1つの高齢者福祉施設にて、2022年4月～2023年3月の期間、CO2濃度・温湿度の連続計測を行った。東京都の2つの小学校は１校が機械換気設備のない区立小学校で、もう1校は機械換気設備をもつ区立小学校である。機械換気設備のない小学校では1年生教室3教室、6年生教室2教室の計5教室で計測を行った。コロナ禍であるため、冷暖房稼働中も窓開放されることが多く特に冬季は室内温度分布が顕著にみられた。機械換気設備のある小学校では1年生教室4教室、3年生教室4教室、6年生教室4教室で計測を行った。オープン型教室である1，6年生教室に比べ従来型教室である3年生教室では、換気設備のオンオフが教室ごとに大きく異なることがわかった。そのため換気設備の稼働状況を把握するシステムを開発した。東京都の1つの高校では機械換気設備のない第一校舎3教室、機械換気設備のある第二校舎3教室の計6教室で計測を行った。機械換気設備のない第一校舎教室では、冬季に換気量が低減する傾向が見られたが、機械換気設備を有する第二校舎教室では、一定の換気量が冬季においても保持されていた。旭川市の計測高校では機械換気設備を有し冷房設備のない校舎の6教室にて計測を行った。旭川市の7月上旬の外気温は高く、室温が快適域を外れていた。宮崎県高鍋町にある小学校の暖房設備および換気設備がなく冷房設備を有する校舎の4教室において計測を行った。暖房設備が無いため、冬季には窓を閉めて温熱環境を維持することにより、換気量が低下する傾向があった。東京にある高齢者福祉施設では、5つの共同生活室、10の個室にて計測を行い、コロナ感染者が出る前、出た後の室内空気環境について考察した。適切な換気量の確保により、二次感染を回避することができていたと考えられる。

Beijing Capital two-year Primary School, Asahikawa City one-year Primary School, Kawasaki one-year Primary School, Kyoto one-year Primary School for the well-being of people in Kyoto, during the period from April 2022 to March 2023, the CO2 temperature and humidity linkage program will be available. In Beijing, there are two primary schools, one school mechanical equipment, one district primary school, one school mechanical equipment, one district primary school. There are 3 classrooms for 1-year-old classrooms and 2 classrooms for 6-year-old classrooms in primary schools. The distribution of indoor temperature in winter is very different from that in the cold and warm rooms. The primary school offers 4 classrooms for one-year students, 4 classrooms for 3-year classrooms and 4 classrooms for 6-year-old classrooms. The 6-year-old classroom is better than the 6-year-old classroom. The 3-year-old classroom is better than the 6-year-old classroom. We should take advantage of the current situation of equipment and equipment to carry out the training program. Room 3 of the first school and classroom 6 of the second school of the Beijing Capital University are scheduled to operate. Mechanical equipment equipment is used in the classroom of the first school, low-temperature equipment in winter is used in the classroom, mechanical equipment is equipped in the classroom of the second school, and a certain amount of equipment is used in the winter season. In Xuchuan city, the equipment of mechanical equipment in Xuchuan city is equipped with cold room equipment and 6 classrooms in Xuchuan city. In the first ten days of July in Asahikawa City, the temperature is high and the room temperature is fast. The primary school in Miyazaki Takashi-cho, the warm room equipment, the cold room equipment, the warm room equipment, the cold room equipment, the warm room equipment, the cold room equipment, the cold room equipment, the warm room equipment, the cold room equipment, the warm room equipment, the cold room equipment, the cold room equipment, the warm room equipment, the cold room equipment, the cold room equipment, the warm room equipment, the cold room equipment, the cold room equipment, the warm room equipment, the cold room equipment, the cold room equipment, the warm room equipment, the cold room equipment, the warm room equipment, the cold room equipment, the cold room equipment, the warm room equipment, the cold room equipment, the warm room equipment, the cold room equipment The greenhouse equipment is free of charge, the winter weather is in good condition, the environment is in good condition, and the quantity is low. In Beijing, the well-being of high-level people will be improved, 5-year-old common living rooms, 10-year-old rooms, and the indoor air environment will be inspected before and after the departure of infected people. Please make sure that the second infection can be avoided, and the second infection will be avoided.
