The Effect of Wall-Mounted Oscillating Fan on Energy Consumption in Built Environments

Abstract

Fans save energy when they complement a regular air-conditioning system and move air at an acceptable speed without compromising thermul comfort. They allow a higher set-point temperature, thus reducing AfC operating hours and saving electrical energy .The study presents derivation for the cornfort thermostat air temperature setting mbnction of air velocity for typical bed room conditions. The typical pn$le of airflow pattern due to wall mounted oscillating fan is shown for representative bed room lay out. The impact of a wall-mounted fan on the energy consumption and AK sizing savings of a bedroom were investigated using energy simulation program, EZDOE 2.10. The study conJirms that fan application achieves sign@cant savings in annual electricity use and reduces AlC sizes, operating hours and extends the neutral hours.
