PARAMETERS COMPARISON OF SOLAR SORPTION REFRIGERATION SYSTEMS

The study showed that absorption chillers and adsorption chillers are effective solutions for providing cooling in both buildings and industrial processes using solar energy. Single-stage absorption systems show a high energy conversion coefficient in the range from 0.50 to 0.73, while adsorption systems have a coefficient from 0.51 to 0.59. The operating temperature of absorption systems ranges from 60 to 165 C degrees Celsius, and adsorption systems — from 50 to 90 C degrees Celsius. Also, the cost of solar cooling systems ranges from 165 to 220 thousand rubles for 1 KW of cooling energy for absorption system, while, the cost of adsorption systems ranges from 220 to 250 thousand rubles1 KW of cooling energy.
