New passive solar panels for Russian cold winter conditions

Abstract We consider our newly developed design for building fencing with multilayer heat storage panels that ensure utilization of solar radiation at the required thermal protection of buildings in cold winter. We report experimental studies of thermal regimes for a model cell in the winter conditions of the Voronezh region, demonstrating energy efficiency. An engineering methodology of thermal simulation based on heat waves superposition is proposed to calculate heat flux in external multilayer fences under the influence of periodical solar radiation, considering the absorbing and heat-accumulating properties of materials. The evaluation of solar energy absorption by external multilayer panels under periodically changing heat fluxes is performed, and the experimental data are found in good agreement with the results of numerical simulations. The business feasibility of this construction and winter operation of buildings using passive new solar panels is shown.
