Sustainable Solar-Based Cogeneration System for Rural Communities: Electrification and Cold Storage Solutions
摘要
Sustainable and locally relevant energy solutions are required due to the growing demand for electricity in rural regions and the need for effective post-harvest crop management. However, several villages in India’s agriculturally wealthy regions experience ongoing power outages, and a large number of vegetables are wasted because they must be preserved in the open air or a hall. This study describes a solar-powered cogeneration system that combines electricity production through the Organic Rankine Cycle (ORC) with the cold storage of post-harvest vegetables using a vapor absorption cycle (VAC). Through the parabolic trough collector, thermal energy is utilized for electricity production via the organic Rankine cycle, while the residual heat is efficiently recovered for use in the cold storage process. Findings show that the cogeneration system successfully provides the communities with the electricity and cooling they require, generating 145.3 kW of electricity with a power plant efficiency of 23.4% and a cooling system coefficient of performance (COP) of 0.54 with 51.17 kW cooling load. Notably, the overall efficiency of the integrated system was recorded at 39.02%. This environmentally friendly method emphasizes how solar energy may be a useful resource for post-harvest vegetable storage and rural electrification.
