Combined absorption power and refrigeration cycles using low-and mid-grade heat sources.

Number: pap. n. 130

Summary

This paper presents several combined absorption cycles proposed for the simultaneous and/or alternative production of power (mechanical or electrical) and refrigeration. The cycles are classified into two groups according to their driving heat source temperature range as low-grade (< 200°C) and mid-grade (< 300°C) combined absorption cycles. Furthermore, the low-grade cycles are classified into two sub-groups, one with a temperature range lower than 100°C and the others with a temperature range between 100 and 200°C. The thermodynamic performance of these cycle configurations were evaluated based on energetic and exergetic performance criteria that consider the thermodynamic quality of their useful outputs in both performance criteria. One particular interesting application of such type of cycles could be the efficient utilization of solar thermal collector installations throughout the year to produce variable amounts of electricity and cooling according to a given building demand in order to minimize the consumption of primary energy.
