The main function of a heat exchanger in an absorption system is to facilitate the transfer of thermal energy between two fluids. In the context of the absorption refrigeration cycle, a heat exchanger specifically helps weak liquor, which has absorbed refrigerant, to gain heat from strong liquor that is rich in refrigerant. This process enhances the efficiency of the system by recovering energy from fluids that would otherwise be wasted and by promoting the concentration of the refrigerant in the strong liquor.

This heat exchange process is critical because it helps to drive the absorption process, thereby improving the overall performance and energy efficiency of the system. The result is a more effective absorption cycle, which is essential for systems that rely on this mechanism for cooling. Understanding this function highlights the importance of heat exchangers in optimizing energy use within these systems.
