Abstract
Solar chimneys may provide enough ventilation to buildings when
properly designed. Although many design tools, theoretical models and
experimental studies have been reported, the impact of many design
parameters such as the construction thickness, the thermal resistance of
the walls, the absorptivity of the internal surfaces of the chimney, the
thermal mass of the chimney and the type of glazing, is not well known.
This paper aims to provide information on the optimum sizing of the above
parameters. Dynamic simulations and sensitivity analysis have been carried
out and specific information on the impact of each parameter is given.
Key words: solar chimney, natural ventilation, design
parameters, absorptivity, thermal resistance, thermal mass, construction
thickness, glazing, thermal simulation.
