Improving the energy efficiency of buildings based on the use of integrated solar wall panels

Abstract

Frequently used facade glazing makes it possible, on the basis of modern trends in the architecture, to increase the energy efficiency of buildings under construction through the organization of passive solar heat supply. Despite the noted relatively low efficiency of the radiation utilization method recommended for the use, it is possible to increase its indicators by integrating the elements of active solar units in the absorbing layer of the accumulating construction structure. For example, the placement of pipes for the coolant in external enclosing structures will allow year-round exploitation of arrays for passive utilization of solar energy and the use of the obtained heat not only for heating rooms during the cold period of the year, but also for heating water, as well as for absorption chillers in the summer season. The application of the latter contributes to the organization of alternative cooling of the internal blocks of air conditioning systems in the warm period of the year. The listed functions require a different approach in the algorithm of the decisions taken in the design of building structures actively involved in the balance of energy supply. One of the main indicators that determine the possible version of the implementation of the solar radiation utilization system is the achieved temperature potential of the heat flux obtained from the surface of the accumulating layer. The use of the method of sources and the principle of the imposition of fields when solving problems of the depth of embedding and step distance integrated into the surface layer of pipes allows determining the rational range of the values of the specified parameters. This, in turn, is aimed at ensuring the possibility of designing energy-efficient exterior enclosing structures that contribute to the maintenance of the thermal regime required by the multifunctional utilization of solar energy.
