Optimized evaporator and generator temperature for the triple-effect absorption cycle.

Author(s) : IVESTER D. N., SHELTON S. V.

Summary

The triple effect absorption cycle is currently garnering much interest in the HVAC community due to its higher COP, both in heating and in cooling modes. The work considers the optimization of the triple-effect cycle when used as a cooling machine. The two-condenser/two-absorber configuration of the triple-effect cycle is considered due to its relatively lower maximum temperature and pressure requirements. Because the triple-effect cycle is composed of two individual single-effect loops, a COP in cooling can be determined for each loop independently. The relationship between the two loops of the triple-effect cycle indicates a possibility that an optimal condition exists where the cooling COP temperature is optimal, even though the cooling COP for the individual loops are less than their maximum values. The analysis considers the heat exchangers which link in two loops together thermally, utilizing the pinch technology approach developed by Linnhoff.
