Method for determining the optimal value of the specific heat capacity and temperature regime of a short-term heat accumulator of passive solar heating systems with a flat reflector of radiation

Abstract

The article presents the results of the analysis and generalization of the experience of operating residential facilities with solar heating systems, even a slight accumulation of the daytime excess heat of solar radiation is determined, which can significantly increase the replacement coefficient of the heat load for heating the systems under consideration. An unjustified increase in the capacity of the heat accumulator has been determined that does not give a noticeable increase in the replacement coefficient for the heat load of the system. Studied and developed new and improved existing insolation passive solar heating systems. The article shows the results of the analysis and operation of residential buildings with solar systems, it is determined that a slight accumulation of daily excess heat of solar radiation can significantly increase the replacement coefficient for the heat load on the heating of the systems under consideration.

The object as the basis for the formation of mechanisms for the prevention of socially dangerous environmental threats

“…We are talking about the continuous digitalization of all spheres of social reality. New calculation methods are being introduced in the energy sector [10]. The construction industry has enormous opportunities to improve productivity and efficiency through digitalization, innovative technologies and new construction methods.…”

Determination of the heat losses of insolation passive solar heating systems

“…Hundreds of different solutions have been proposed and demonstrated [1]. For a direct solar heating system, the simplest is to use heavy curtains with tightly closed tops to cut off the convective heat flow between the curtain and the glass.…”

“…Of the non-traditional and renewable energy resources in the conditions of the Republic of Uzbekistan, solar energy is the most promising, the energy potential of which is 98.5% of renewable energy sources combined [1][2].…”

“…In the conditions of our Republic, the relevance of using solar energy in heat supply systems as a source of low-grade heat is due to the fact that at present, out of all the heat energy generated in 2000 (46.4 million Gcal), 50,4% was spent for low-temperature needs of the population ( 33.6%) and household sector (16.8%) [1][2][3][4][5][6].…”

Modeling the temperature regime of the heat accumulator

“…It is advisable to use solar energy and heat accumulators together with the heat waste of various heat-technological devices for heating. Accumulators that store heat from several days to three months are needed for maximum efficient use of solar energy for heating [1][2][3][4][5][6][7][8][9][10].…”
