Analysis of the Solar Wall Heat Transfer and Energy Saving of Residential Ventilation

Abstract:

It is the considerable measure that adopting the ventilation solar wall to make up the indoor air in winter because this method embodies the effective use of renewable energy. This paper analyzes the needed volume of make-up air in the different conditions of indoor air exhaust in winter and builds a solar wall to heat the make-up air. Under the conditions of different solar wall size of air channel thickness and so on, Conclusions can be simulated by using CFD software. When the optimum cavity width B is 50mm, the height of air supply outlet D is 30mm and the volume of make-up air is 200 m3/h,the maximum temperature rise of the air rises to 24°C.But when the volume of make-up air is 600 m3/h, there has the best energy-saving effect.
