jismart2019046: Thermal Sensation Significance on Thermal Condition for Workers in Hot-humid Climate

Abstract

Around 50% of energy consumption is usually associated to indoor space with its HVAC (heating, ventilation, and air conditioning) system, especially in tropical Asia case. There were some challenges regarding controlling the indoor air condition in hot humid climate like Indonesia. To see the occupant’s responses, humidity and air temperature become one of the important controlled parameters. This paper aim to find the relation and significance between the controlled thermal condition, such as the air temperature and humidity in the climate chamber with the temperature sensation and humidity sensation from occupant’s responses after adapted inside the test room. Collected data were analyzed with ANOVA to find the relation and significance between variables. Based on analysis, the most neutral sensation comes from 25℃ air temperature and 50% humidity. Air temperature has more significant relation with thermal and humidity sensation, while the humidity only influencing the humidity sensation. The result of this paper will be a first step to find the thermal comfort in hot humid climate, with Bandung as case study.
