PLANNING EXPERIMENT FOR INVESTIGATION OF FACTORS AFFECTING THERMAL PROCESSING HEATING CONSTRUCTIONS AT THEIR THERMOMODERNIZATION

Abstract

Today, in the absence of sufficient quantities of fuel, the reduction of energy consumption in the residential sector is important for Ukraine. This will not only save the resources spent on heating residential buildings, but will also reduce the harmful impact on the environment. The modern way of Ukraine in the direction of energy saving increases the requirements for heat-protective structures, increasing the value of thermal resistance. Therefore, it is necessary to improve them. It is important to pay attention to the sites of adjoining fencing structures of the building, as there are so-called "bridges of cold". Studies have shown that up to 30% of heating energy is lost through such sites. The appearance of "bridges of cold" is primarily due to the materials used and the design features. Modern normative documents do not provide effective technical solutions for reducing heat losses due to thermal heterogeneity of external enclosing structures of buildings. In connection with this, it is necessary to develop design solutions of thermal insulation systems of the adjacent nodes, which will reduce the probability of the occurrence of "bridges of cold" and in turn will increase the energy efficiency of the building. The characteristics of the heat-insulating material play an important role in increasing the thermal resistance of the structure. Today, there are a variety of heat-insulating materials that differ in their properties and cost. In view of this, it is necessary to select the most optimal parameters of the thermal insulating structure for the adjacent units, which would meet the regulatory requirements. For this purpose, the influence of the thermal insulation parameters on the thermal resistance of the construction on the basis of the two-factor experiment was carried out. From the parameters that have the greatest influence on the thermal resistance, the thickness of the heat-insulating material and its density are chosen.
