Abstract

This study serves as a foundation investigation to gather essential data for developing an algorithm to predict and prevent condensation using a Steam Sensor. In addition to utilizing temperature data typically employed in existing condensation prevention methods, the Steam Sensor was incorporated to monitor the continuous and discontinuous condensation behavior. This allowed for the collection of fundamental data for real-world condensation prediction and prevention. Before conducting the experiment, the heat flow rate for windows exposed to outdoor air using ISO-9869 was measured and validated. Indoor temperature and humidity were controlled through Arduino programming based on open-source platforms to observe the distribution of these factors. Subsequently, condensation was artificially induced by manipulating temperature and humidity conditions, then measured it with the Steam Sensor. During the experiment, as the indoor temperature was raised, absolute humidity and dew point temperature increased, resulting in an increase in the measured Steam Sensor values. When indoor humidity levels rise and the humidifier operates for an extended period, the accumulation of water vapor within the room increases. This elevated moisture level was detected by the Steam Sensor, and the condensation persisted until the end of the measurement. The experimental data gathered in this study will be valuable for future research where the aim is to develop a condensation prediction algorithm through machine learning techniques.
