Description
Summary:Solar cooling systems are considered a logical solution to the problems of combating climate change. In this study, a mathematical model of a combined type of solar collector for daytime heating and nighttime radiation cooling was developed for its use in a single-effect absorption water-lithium bromide cooler in the weather conditions of the city of Bamako in summer. It is shown that the effective operation of the system is achieved at a temperature in the generator of 85 °C, a temperature in the condenser and absorber of 40°C and a temperature in the evaporator of 10 °C. The coefficient of performance of the single-effect absorption cooler reaches 0.87 and the coefficient of performance of the whole system is 0.64.
