“…In the case when the covering is the Grafplast PDA on the solar collector and using Prandelli/Tuborama pipes with diameters of 0.016 m and 0.025 m with radiation intensities of 500 W/m 2 and 1000 W/m 2 , the efficiency of the solar collector is visible in Figures 12 and 13, respectively, when the heat carrying flow rate is equals 1-G = 0.0125 kg/s; 2-G = 0.00833 kg/s; and 3-G = 0.00417 kg/s. The analysis of diagrams (Figures [7][8][9][10][11][12][13] shows that the diameter of the tubes and the distance of their arrangement have a minor effect. That is why it is convenient to present the Grafplast-coated panel efficiency depending only on the heat flow and mass flow rate of the heat carrier.…”

“…Ukraine's territory is characterized by a moderate intensity of solar radiation. Research [10] proved that solar radiation flow is increasing the number of sunny days as well; in the north-south direction there is a corresponding increase of specific solar radiation flow per 1 m 2 during a year.…”

The background of this article is the potential energy savings of solar heat supply systems due to the use of the renewable energy of solar radiation. The motivation is to create a solar collector design that would combine the functions of both a building cover and a solar collector. It is necessary to investigate and compare different types of solar collector coatings (traditional and modern) and pipe diameters. The purpose of the article is to solve aspects of energy efficiency for new eco-friendly solar collectors. The most effective result occurred with the solar collector covered with the rubber–graphite composition of Grafplast PDA, and when using Prandelli/Tuborama pipes with a diameter of 0.016 m. Their efficiency increased by 8% compared to the second version of the collector made using a more traditional solution. The influence of the distance between the pipes and the flow rate of the heat carrier on the efficiency of the solar collectors was evaluated.

“…Of course, an important aspect of the building's energy efficiency remains its architectural features, in particular the size and orientation of the building block, as well as the efficiency of the operation of internal engineering networks. A smart combination of external protection and receivers of solar energy and converters of it into thermal energy allow to ensure the functioning of heating systems and hot water supply systems [1][2][3][4][5][6][7].…”

The proposed Trombe wall design is an innovative and effective solution for addressing issues related to building energy efficiency. The Trombe wall can help reduce a building's energy consumption, provide optimal indoor temperature, and minimize the building's environmental impact by utilizing renewable energy sources.The article deals with the study of the heat-air characteristics of the Trombe Wall, which performs the functions of external protection of a modular house, with the aim of further evaluating the possibility of using it as a hybrid protection with additional heating and ventilation functions assigned to it. The results of experimental research conducted on one of the elements of external protection of a modular house in the form of the Trombe Wall are presented. The experimentally obtained graphic dependences were compared with the calculated data and the convergence was evaluated. The proposed design allows you to organize air exchange in the premises with a multiplicity within 1-1.5 h −1 , and also provides an opportunity to provide additional thermal power in the amount of 250 W/m 2 . The article presents the results of experimental studies that allow to evaluate the thermal characteristics of the proposed design of external protection for a modular house. These results indicate that with the given geometric dimensions, in particular with a volume of 14 m 3 , the thermal power utilized by the Trombe wall is within 0.2-0.7 kW.
