Objective. Night radiative cooling (Radiative cooling) is based on the phenomenon of Earth's effective radiation, in which heat is removed into the atmosphere and partially carried away into outer space, which leads to a decrease in the temperature of objects located on the Earth's surface below the air temperature in the surface layer.Method. The research is based on methods of thermodynamic analysis, full-scale and computational modeling of processes and objects of refrigeration and cryogenic technology. On the basis of the method developed by the authors and the existing method, a computational and theoretical analysis of radiative cooling for the Euro-Asian continent was carried out. As a result, the regularity of the change in the radiative cooling potential depending on the geographic latitude was determined, starting from the equator to the northernmost point of the continent. Schematic solutions and designs of refrigeration systems of various functional purposes for various regions with yearround use of radiative cooling have been developed. Theoretical and experimental studies of installations with radiative cooling are presented. for food storage and air conditioning was carried out.Conclusion. On the basis of the developed computer model, an analysis of the energy efficiency of refrigeration systems for food storage and air conditioning, in which the object is cooled by radiative cooling and a vapor compression refrigeration machine, was carried out using the simulation of the annual operation cycle in continental climatic conditions.
