Constructive Features of the Device “Trombe Wall” During Thermal Modernization of the Existing Building

The article presents a constructive solution for the modernization of the enclosure structures of the operated building. Measures were taken to reduce the annual power delivery for heating. A comprehensive approach has been implemented by combining measures to increase the heat transfer resistance of enclosure structures and the introduction of solar heating systems. In particular, it is proposed: replacement of translucent parts with energy efficient ones; heat insulation of opaque parts of the walls; arrangement of two partitions of the southern wall in the form of elements of passive solar heating - “Trombe Wall”. The constructive decision of an element of passive heating does not demand installation of the additional equipment and saves the useful area of the room. To preserve the carrying function of the partition when installing thermal insulation from another wall array, it is proposed to use the method of perforation. Experimental design of complex modernization of the shell and heating system of the existing residential building has been performed. The comparison of initial and design heat needs confirmed the feasibility of introducing a set of energy efficient measures, in particular, the integration into the existing heating system of the house of a passive heating element - “Trombe Walls”. The introduction of elements of the passive heating system, which works on the principle of utilization and use of solar radiation on the scale of a single house has reduced the total cost of heat generation during the heating season by 6%.
