This work deals with the comparative study of different rectification methods on the performance of a 10 kW NH3-H2O absorption refrigeration machine. Three types of rectifiers, namely packed columns, tray columns and partial condensation (single) columns were studied. Numerical simulation of the mathematical model of the absorption machine shows an identical COP profile for the three types of rectifiers. Modification of a 0.43 performance absorption machine previously operating with a single rectifier resulted in 7% and 11% performance improvement for tray column and packed column rectifiers, respectively.
Author Keywords: Absorption, refrigeration machine, ammonia-water, rectifier, packed column, tray column, coefficient of performance.

Three types of rectifiers, namely packed columns, tray columns and partial condensation (single) columns were studied. Numerical simulation of the mathematical model of the absorption machine shows an identical COP profile for the three types of rectifiers. Modification of a 0.43 performance absorption machine previously operating with a single rectifier resulted in 7% and 11% performance improvement for tray column and packed column rectifiers, respectively.
