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/m2. 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 m3, the thermal power utilized by the Trombe wall is within 0.2-0.7 kW.

The world is increasingly paying attention to the use of so-called renewable energy sources - ground heat, wind energy, tides, biogas, solar radiation, and so on. Almost all of these energy sources are entirely due to direct influence from the Sun. Among these sources, one of the most promising is the direct conversion of solar radiation. The direct conversion of solar energy into heat or electricity is one of the main advantages of using solar energy as a future energy resource. The article presents the actual use of solar systems to provide hot water and electricity to educational and health establishments.

The situation in the country and around the world needs new, better energy resources and ways to use them to save energy, and with it, the economic, ecological and social position of any state. Energy saving is a necessary issue for improving economic performance by reducing energy consumption while maintaining comfortable conditions. Large industrial buildings are a significant consumer of thermal energy. An effective approach is needed for the design of heating systems, taking into account the possible modes of their operation to ensure the rational use of energy resources.

Podczas kształtowania warunków mikroklimatu w hali produkcyjnej dużą uwagę przywiązuje się do stosowania wysoce wydajnych, energooszczędnych i ekonomicznych systemów. Zarówno na Ukrainie, jak i na świecie bada się różne aspekty zastosowania systemów grzewczych na podczerwień do ogrzewania pomieszczeń produkcyjnych. W artykule omówiono eksperymentalne badania dotyczące wyznaczania temperatury napromieniowanych powierzchni i gęstości strumienia energii promieniowania w zależności od trybu pracy, mocy i wysokości zainstalowanego promiennika podczerwieni.
