Application of a developed adaptive model in the evaluation of thermal comfort in ventilated kindergarten occupied spaces
Abstract In this work the application of a developed adaptive model in the evaluation of thermal comfort in ventilated kindergarten occupied spaces is made. The study, conducted in real conditions, in mediterranean environment for cold and warm thermal conditions is made. The adaptive model is developed in a Kindergarten, using subjective and experimental measurements. Three different trained groups of subjects are used. Each one expressed its thermal subjective response, in different classrooms, for cold and warm thermal conditions. In the study, the classrooms are ventilated by natural airflow, while the indoor playground is ventilated by forced airflow. The natural airflow in the classrooms is measured using tracer gas decreasing concentration. The measurements are made for different window states, from close state to open state. In both warm and cold thermal conditions the simulation is made in real occupation and ventilation conditions. The natural ventilation is promoted, in both thermal conditions, using experimental measurements. In cold thermal conditions the forced airflow is done from the greenhouse to the indoor playground, while in warm thermal conditions the forced airflow is done in the opposite direction. In the thermal comfort level evaluation the developed adaptive model is used, while in the air quality level evaluation the carbon dioxide concentration released by the occupants is used.
Highlights ► Evaluation of comfort in ventilated kindergarten occupied spaces. ► We develop an adaptive model using subjective and experimental measurements. ► The natural air renovation rate was developed using tracer gases. ► In winter conditions, we have good levels of thermal comfort within the category C. ► In summer conditions, the indoor air quality is acceptable with CO2 below 1500 mg/m3.
