SIMULATION OF THE THERMAL MODE OF THE UNIT OF THE ACCESSION OF A BALCONY PLATE WITH INSULATION

Abstract

The results of thermal imaging examination of a multistory residential building, which indicate the presence of "cold bridges" in the junction of the adjacent balcony slab to the outer wall. An improved design of the energy-saving node of the adjacent balcony slab is proposed. In it on an external wall in the place of its adjoining to a balcony plate put a gluing solution on which place the heater on which impose a reinforced grid. Apply a primer and decorative plaster on top of the grid. Inside the outer wall, on its inner side at the place of adjoining the balcony plate, arrange a layer of insulation in the form of an airgel plate, and over the balcony plate stack plastic film. Next, place a heater, which is applied cement-sand mortar reinforced with fiberglass mesh. As a result of modeling the distribution of heat fluxes in the existing and proposed nodes of the adjacent balcony plate to the outer wall, it is established that the use inside the outer wall at the place of its adjacent to the balcony plate allows to reduce heat losses at the junction node.
