Performance analysis of air curtains on indoor environment and dehumidification energy consumption in a low humidity plant

The purpose of this study is to evaluate the effect air curtains on indoor environment and dehumidification energy consumption for different supply angle velocity. numerical investigation conducted in a low-humidity plant located atmospheric boundary layer. standard k-epsilon turbulence model used simulation study. optimum velocity are evaluated based temperature humidity distribution. cases range from 0° 20° 6 m/s 14 m/s, which studied by means orthogonal experiments. Simulation results show that curtain can reduce average up 3.9°C moisture content 86.6%. saving assessment rotor system shows parabolic variation with increasing at certain angle. occurs 9–11 When over 11 airflow exchange enhanced opening, resulting higher leakage dehumidification.
