Abstract: This article is devoted to the use of the polymer K-9 reagent in porous claydite-ash concrete and the design of its optimal composition according to the general design method of the optimal composition of the general theory of artificial building conglomerates (ISC). The data of experiments confirming the positive effect of the polymer reagent on increasing the durability, improving the moisture and heat engineering modes of porous concrete are presented.

In this article focuses on the hydrodynamic processes that occur in the solar air heater collector with a bottomless triangular channel working at the expense of solar radiation. Factors that directly affect the heat exchange processes in the working Chamber of the solar air collector with an overhead triangular shape have been analyzed, including air flow in the channels, heating surface structures, acceleration of the heat exchange process and methods for calculating the main indicators such as pressure loss. The solar air heater is one of the main and widely used equipment that can convert solar energy into useful thermal energy. Solar air heaters are economically efficient due to their simple structural structure and can be widely used in household and industrial sectors. The main area of application of solar air heater collectors is heating, in addition to agricultural, fruits and vegetables, including various products, the drying of technological products can be widely used.

In this article study attempts to study the thermal performance of solar air collectors with submersible air ducts and pipes. This study is conducting numerical analysis of the solar collector with pin wings and turbulators to study the effects on the Nusselt number. The paper begins with a numerical analysis of conventional air collectors and compares them with theoretical results. Reynolds numbers range from 2000 to 2500. Next, after the solar collector's performance is evaluated with the bath air with channels, the effects of turbulators of different heights on the Nusselt number are analyzed, followed by the combined effects of pin wings and turbulators. The results are comparable to conventional solar collectors, and suggest that the combined effects of pin wings and turbulators can significantly improve the thermal performance of solar air collectors. The results of this study may contribute to the development of renewable energy-based air conditioning, ventilation and heating systems.
