EXERGY ANALYSIS OF HALF-EFFECT ABSORPTION COOLING CYCLES
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 9
Abstract
Absorption cooling cycles are environmental, clean and economically driven cycles. By consuming very small electric power, they can use waste heat or solar energy for cooling. This work presents exergy analysis of a half effect absorption system. A computer program is developed by the author in FORTRAN codes for the thermodynamic properties of lithium bromide-water solutions to use for the exergy analysis. The half effect absorption systems have the advantage of using low temperature heat energy for cooling. The coefficient performance (COP) and the exergetic coefficient performance (ECOP) of the half effect absorption systems are found as 0.45 and 0.24, respectively. For each component the exergy loss is calculated. Most of the irreversibilities are found in the evaporator and in the absorbers. It is concluded that the half effect absorption systems is the best for cooling driven by low temperature heat energy and the performance of the evaporator and the absorbers is very important for the cycle.
