Exergoeconomic, enviroeconomic and sustainability analyses of a novel air cooler

Abstract This study presents the energy, exergy, environmental, exergoeconomic, enviroeconomic and sustainability analyses of the Maisotsenko cycle based novel air cooler considering the nine different dead state temperatures, while the environment temperature is kept constant. In the energy analysis, the wet bulb and dew point effectivenesses, cooling capacity, energetic coefficient of performance and primary energy ratio rates are calculated. Also, in the exergy analysis, exergy input, output, loss and destruction rates as well as exergetic coefficient of performance and primary exergy ratio and exergy efficiency values are determined. Furthermore, sustainability analysis of the system is conducted through a sustainability index method. The electrical energy consumption cost of this novel air cooler shows that, it consumes only 59.85 $/year, when it is operated 8 h a day and 125 days in a year. The maximum exergetic cost rate is found to be 0.0228 kWh/$-year at a dead state temperature of 37.77 °C. Also, according to the enviroeconomic (environmental cost) analysis, this novel air cooler has very CO2 emissions cost as 6.96 $/year. Consequently, these results show the originality of the Maisotsenko cycle based novel air cooler.
