In the article, the results of the temperature of the autonomous helio-greenhouse of the trench type in the abnormal cold climatic conditions of Uzbekistan are discussed. During the winter heating season at ambient temperatures from -40 °C to -21 °C, experiments were carried out, which showed that at an outdoor air temperature of less than -10 °C there was no need to use emergency heating sources, and the temperature in the autonomous greenhouse dropped to 5 °C. A two-circuit combined system based on an electric boiler and a solar water heating system has been proposed and applied as an emergency heating source. At an ambient temperature of more than -200 °C, the air temperature wizened at ~8-8,5 °C with the use of the additional water heating system (AWHS) and the photovoltaic system in the autonomous heating unit. The actual shares of the density of the flow of solar radiation within the greenhouse are established when compared with the total densities of the flux of sun radiation falling on the transparent surface of the object under investigation, covered with snow of varying thickness. In the course of the studies, the analysis of the temperature gradients of panel radiators with the help of a thermal visualizer and the content of the air environment of the internal part of the object under investigation with the aid of a gas analyzer was carried out.
