Performance of rectifying column affects the coefficient of performance (COP) in an ammonia absorption refrigerator (AAR). Refrigerant mass fraction is one of the key parameters to discuss the performance of the rectifying column. Focusing on the refrigerant mass fraction, this paper presents a method to estimate the refrigerant mass fraction with mass and energy balance and the result of the experiment which measures refrigerant mass fraction by sampling from the refrigerant receiver. Through out these investigations, the refrigerant mass fraction became lower than the expected value which is calculated from the condition of saturated vapor at the top of the rectifying column. We confirm that the refrigerant mass fraction could be estimated with sufficient accuracy from mass and energy balance equations around the separator at the inlet of the evaporator.
