Exergoeconomic, environmental, economic, and energy-matrices (4E) analysis of three solar distillation systems equipped with condenser and different heaters

The water scarcity in the world near future become to a global challenge. main aim of present study was elucidate performance three identical solar distillation units with different configurations under climatic conditions city Tehran. All systems were equipped heating source that are thermoelectric modules (TEH), copper heater (CH), and (SWH) while all system assisted an active external condenser. Performance is scrutinized from thermodynamic, thermoeconomic, environmental, energy-matrices viewpoints. Findings revealed highest daily annual productivity obtained by CH. Economic analysis on basis uniform cost (UAC) SWH has lowest per liter (CPL) rather than other CPL for case TEH. Furthermore, it concluded TEH obtain most promising results terms exergoeconomic, enviroeconomic, energy payback time (EPBT) because exergy output. Eventually, environmental indicated still CH 6342, 48.169, 18.46 kg emission CO2, SO2. And NO have best
