However, frequently the size of the absorber is bigger because the absorber heat and mass transfer
coefficients for the working mixtures are low [5], in addition, Second Law thermodynamic analysis
shows the highest exergy loss occurs in the absorber, due to the temperature difference between the
absorber and the surroundings [6–9]. This can be reduced by increasing the surface area of the
absorber, consequently increasing its cost. Numerical analysis shows than heat and mass transfer
absorber effectiveness has a significant influence on the absorber performance cycle. Mass transfer
absorber effectiveness can reduce the generator heat power supply when the absorber dilution has a
great value and it reduces the exergy loss when high heat transfer effectiveness values are achieved,
therefore, increasing the COP [10,11]. In order to increase the heat and mass transfer coefficients,
several absorption designs have been reported, which use different ways for that: increasing the heat
and mass transfer area, increasing the vapour refrigerant pressure or improved mixing of working
fluids. The aim of this paper is to provide a background with a review of the literature on absorber
design and its performance in absorption cycles. It is expected that this paper will be useful for any
researcher in the field of absorption cycle technologies
