Study on different office cooling systems on workers by subject experiment (part 1): Effects of indoor environment difference due to office cooling systems on skin temperature, psychological quantity, and workplace productivity

Increasing the productivity of workers has great economic value and is essential for achieving a sustainable society and economic progress. Therefor the purpose of this study was to clarify the effects of different air-conditioning systems on human response and productivity. The following findings were obtained by this experiment. The skin temperature difference was larger in convection air conditioning than in radiant air conditioning. Male and Female differed in thermal environment satisfaction and air flow comfort for air conditioning and air velocity. Skin temperature difference, thermal environment satisfaction, and airflow comfort affected fatigue, and productivity increased when not tired.
