Summary

Paper published in poster form during the conference. A more intuitive exergy efficiency calculus is proposed for absorption and mechanical vapor compression cooling, heating and working cycles. According to a lemma proved, the exergy efficiency of these cycles equals the relative to Carnot efficiency. Other simple thermodynamic processes obeying lemma are presented too. A basic theorem shows that 1st principle effectiveness COP has an exergy like behavior and it is linked together with entropy source in energy-processes and with natural force of non-equilibrium phenomenological thermodynamics in open steady-state physical and chemical processes. Two ammonia applications close paper.
