Matematički modeli sistema za hlađenje pokretanih energijom sunčevog zračenja

Considering the increasingly intense and obvious climate change and the increase in global temperature, as well as the growth of the world population and the accelerated process of population migration from rural to urban areas, the energy consumption for cooling residential and commercial spaces is constantly increasing, with a tendency to continue to increase rapidly. On the other hand, given the widely accepted theory that the increase in global temperature is caused by increased anthropogenic emissions of greenhouse gases, transitioning from fossil fuels to renewable energy sources (RES) has been established as a key strategy for slowing this temperature rise. In this sense, linking the growing demand for cooling energy and the transition to the use of RES, the use of solar energy for cooling purposes is imposed as an optimal solution. This is supported by the fact that, among all types of RES, the use of solar energy is the most promising because it is inexhaustible, available everywhere and almost without the effects of environmental pollution. In addition, the demand for cooling is greatest precisely when solar radiation reaches its maximum, and the need for cooling is greater in areas with a warm climate. One of the possible technologies that enable the realization of the cooling process using solar energy is absorption refrigeration systems. Due to the development of increasingly efficient systems for collecting and storing solar energy, there are many reasons for increasing research in the field of absorption refrigeration systems. In addition to explaining the working principles and observing energy flows, and determining the energy efficiency of these systems, this paper presents the mathematical models of cooling systems powered by solar radiation that have been developed so far and their thermodynamic analysis has been performed.
