ANNOTATION

This paper proposes a method for studying heat fluxes inside building envelopes based on the theory of non-stationary thermal conductivity with periodic harmonic fluctuations in air temperature. The process of energy storage, heat gain (heat inflow) and heat loss (heat outflow) through the building envelope are studied as a periodic harmonic process. The results of theoretical studies of heat flows through flat walls and roofs, enclosing structures of buildings in the climatic conditions of the northern valleys of the Republic of Tajikistan are presented.

KEY WORDS

unsteady thermal conductivity, thermal stability, heat input, thermal conductivity, heat flux, accumulated thermal energy, building envelope.
