Development of a new control strategy for improving the operation of multiple shades in a solarium

摘要

This paper presents a new control strategy for improving the performance of one interior and/or exterior planar shade(s). The control strategy is based on performing an energy balance on the fenestration system and calculating the total heat flow (i.e. solar gains + overall heat losses). The heat flow can be maximized or minimized depending on the needs of the space. A solarium model was developed in order to assess the performance of the proposed shading strategy. The solarium model can simulate passive and active thermal storage using sensible and phase change materials. A prototype solarium with motorized interior and exterior shadings has been instrumented and subjected to controlled conditions. The numerical simulations are in good agreement with experimental results.
