Influence of Control Strategies and Occupant Behavior on Energy Consumption of a Direct Evaporative Cooler in Tehran

K. Naeiji, K. Rückert

Abstract: This paper looks into the influence of occupant behavior on the electricity consumption of a manually controlled DEC and comparing it with one that is controlled automatically by a thermostat. Based on the adaptive thermal comfort theory, an algorithm for manual control of windows and DECs is proposed and it is integrated in the EnergyPlus software by its Energy Management System (EMS) feature. The results show that the electricity consumption of a thermostat controlled DEC is strongly related to setpoint temperature; for instance, at the setpoint temperature below 26 ºC a thermostat controlled DEC consumes more electricity than a manually controlled one. However, at setpoint temperature 29 ºC -which it provides the same amount of thermal comfort as a manually controlled one- the electricity saving is about 60%.
