This paper reports the primacy of dry expansion type Ammonia Absorption Refrigerator (AAR) without reflux pump system over the ordinary cycle (ARS) especially about COP. AAR is demanded to compact for the market. AAR without reflux pump system was developed, but revealed surplus cold energy at bleed. For the solution of that, dry expansion type AAR without reflux pump system is contrived. As a result, when compared with ARS, this system is effective at an evaporating temperature over -45[℃] about COP. In addition, it doesn't need reflux pump system, bleed heat exchanger, gas-liquid separator and receiver, but the number of trays in the rectifying column increases at an evaporating temperature under -30[℃].
