Thermal efficiency of the enclosing structures of an individual residential house in conditions of interconstant thermal energy generation

Abstract

The involvement of recycled wood resources and low-quality wood in the processing provides an active source of raw materials for the construction industry. Environmentally friendly building materials in the form of wood-mineral composites (WMC) help recycle this waste and help conserve natural resources. The study examined the thermal performance of enclosing structures in the form of a frame wall filled with mineral wool, walls made of aerated concrete blocks and stands made of WMC. The purpose of the work was to determine the thermal regime of enclosing structures under stationary and non-stationary thermal conditions. The unsteady mode was created by simulating the generation of thermal energy for 10 hours a day. The mode corresponds as closely as possible to the actual operating conditions of an individual housing construction project, provided that it is heated by a solid fuel boiler or stove with periodic generation of thermal energy. The total simulation time is 5 days. It has been established that in a stationary thermal mode, all considered structures comply with sanitary and hygienic requirements and heat conservation standards.
