Institute for Energy Engineering, Technical University Berlin ABSTRACTThe Maisotsenko-cycle (M-cycle) is a complex process associated with humid air. Heat transfer and evaporative cooling occur in a unique indirect evaporative cooler, resulting in product temperatures that approach dew point temperature. The different applications of the M-cycle contribute to effective energy savings. By enhancing cooling towers with the M-cycle it is possible to (a) cool water to temperatures approaching dew point temperature and (b) reduce the pressure drop and the required fan power. An exergetic analysis identifies the real thermodynamic inefficiencies and the potential of improvement of energy-conversion systems. This paper discusses the results obtained from a detailed exergetic analysis of the M-cycle applied to a cooling tower. In the analysis physical and chemical exergies are considered and the physical exergies of all material streams are split into their thermal and mechanical parts. The paper concludes with a sensitivity analysis. |
