Ammonia absorption refrigerator is an energy conservation equipment that can be driven by waste heat comes from primary generators in cascade. Some of the challenges for the ammonia absorption refrigerator are high efficiency, low-cost, and lowering the heat source temperature. The authors have been shown that lowering the ammonia mass fraction of the refrigerant makes the heat source temperature. This paper reports some results of experimental investigations on an ammonia absorption refrigerator to confirm the validity of our theory. The experimental refrigerator is a single-stage absorption refrigerator of 350[kW] cooling capacity. The rating heat source temperature is 161[℃] and the refrigerant mass fraction is 99.8% at the top of the rectifying column. Experimental investigations are carried out with a parameter of the temperature at the top of the rectifying column which determine the ammonia mass fraction of the refrigerant.
