Performance of rectifier affects the coefficient of performance (COP) of an ammonia absorption refrigerator. Ammonia, namely refrigerant mass fraction, is one of the key parameters to discuss the performance of the rectifier. Focusing on the refrigerant mass fraction, this paper presents a method to estimate the refrigerant mass fraction with mass and energy balance and the results of the experiments which measures refrigerant mass fraction by sampling from the refrigerant receiver. Through out these investigations, the refrigerant mass fraction was lower than that of the expected value which is calculated from the condition of dry-saturated vapor at the top of the rectifier. The refrigerant mass fraction can be estimated within an accuracy of 0.7% from mass and energy balance equations around the separator at the inlet of the evaporator.
