Exergy destruction in air cooling single-effect and multiple-effect lithium bromide thermal compressors.

Author(s) : IZQUIERDO M., VEGA M. de, LECUONA A., et al.

Summary

The absorption heat is directly transferred either to water or to the air. Air cooling systems work with temperature and pressure gradients higher than those cooled by water. Absorption temperature in air-cooled systems can reach and even exceed 50 °C. Under these conditions, boiling temperature within the high desorber of double and triple-effect can exceed 200 and 300 °C respectively. The thermal compressor cooled by air destroys more exergy than the one cooled by water. The triple-effect thermal compressor destroys less exergy than the double-effect one and the latter less exergy than the single-effect one.
