Abstract: An assessment of the cascade adsorption-compression refrigeration system by adopting renewable energy for cold storage applications based on energy, exergy, exergoeconomic, and enviroeconomic perspectives is presented. The cascade cycle aims to dwindle the electric power of the compression subcycle with reduced condensation pressure. The thermodynamic modeling of the proposed system is developed at climatic conditions of Alexandria/Egypt for two scenarios of renewable systems, including (i) biomass-solar (Scenario-I) and (ii) biomass-solar-wind (Scenario-II). The results demonstrate that the COP of the cascade system is ameliorated by 41.6% compared to the conventional compression system; highlighting an energy saving of 42%. The proposed system has an annual average COP and exergetic efficiency of 0.122 and 1.78%, respectively for Scenario-I and 0.124 and 1.8%, respectively for Scenario-II. Scenario-I and Scenario-II deliver refrigeration at 0.235 $/kWh, and 0.237 $/kWh, respectively. Herein, the exergoeconomic parameter for Scenario-I and Scenario-II is 0.70 kWh/$ and 0.69 kWh/$, respectively. It is found that both scenarios alleviate about 32.75 and 5.35 tons of CO2 per annum based on environmental and exergoenvironmental standpoints, respectively. Besides, the enviroeconomic and exergoenvironmental parameters are about 474.90 $/kW and 77.60 $/kW respectively, over the project lifespan of 20 years for both scenarios.
