Theoretically possible cooling capacity of an ideal refrigeration system using the effective radiation into space was calculated by two methods. The calculations were performed for the cities located from 43 ° to 59 ° north latitude: Almaty, Vladivostok, UstKamenogorsk, Petropavlovsk, Omsk, Kazan, Moscow and St. Petersburg. The graphs of the total amount of cold for the year and for some months depending on the temperature of the radiating surface are shown. It is found that the greatest amount of cold for the year can be produced in the climatic conditions of the city of Omsk, and the smallest in Almaty. A method for estimating the amount of heat withdrawn from the radiator due to convective heat transfer through the cooling degreehours is developed. The results of the calculation of the cooling degreehours for the year for all of the above cities are presented. Also graphs in the article are showing how many hours per year the temperature in each of the cities is below given temperature. With the help of these graphs it is expected to make an assessment of the working time of the refrigeration system during the year. In the summer period due to effective radiation the coolant temperature can become not lower than 15...20 °C. In the winter, it is impossible to use the effective radiation for stable cooling to a temperature below -10 °C all reviewed cities. The data obtained can be used in the design of cooling systems of the considered type, as well as in the standard refrigeration systems that use natural cooling (Free cooling).
