Influence of Ceiling fans on Space Heating

Abstract

Simple equations was devised to get a preliminary insight into the effectiveness of ceiling fans in removing temperature stratifications developed naturally in heated spaces. The model was also used to assess the consequences of temperature stratification. Exergy relations were derived based on the one-dimensional model to analyze the problem from exergy destruction perspective. Temperature measurements in a heated space middle plane reveal high-temperature stratifications. About 40% reduction in temperature stratification was measured after using ceiling fan.
