Thermal comfort and indoor air quality in the lecture room with 4-way cassette air-conditioner and mixing ventilation system

For that paper, experimental and numerical studies on thermal comfort and indoor air quality were performed in a lecture room with cooling loads when the operating conditions are changed. The results have been compared and showed a reasonable agreement with each other. From those results, the authors found that the increment of the discharge angle of 4-way cassette-air conditioner makes uniformity of the thermal comfort worse, but scarcely affects IAQ. The variation of the discharge airflow rarely affected thermal comfort and IAQ
