An investigation of the heat absorption and transmission into a scaled building structure installed with a fluidic window

Abstract An analytical and experimental investigation of the heat transfer into a scaled building structure that is exposed to a radiant heat source is reported in this paper. The aim of this study is to evaluated the reduction in the equivalent Solar Heat Gain Coefficient (SHGC) of fluidic window concept against conventional building windows. A mathematical description of the heat transfer through the fluidic window is developed by conserving the heat and fluid flow in and out of the window. Experimental investigation is carried out to verify the heat transferred evaluated from the mathematical model. The result shows that fluidic window is effective at redirecting the heat away from the interior of the building structure as showed by the reduction in indoor air temperature. The indoor air temperature rise in the scaled building structure under steady heating conditions with the fluidic window installed has been reduced by 10∘C. The reduction in indoor air temperature represent significant energy savings in building cooling and ventilation by reducing the cooling load required. Moreover, the amount of heat that is redirected or captured in the fluid represents a potential source of recoverable heat energy which could be recovered.
