1 To separate the liquid out of the gas returning from the evaporator. The equation after simplified is. Ammonia refrigeration systems have traditionally employed evaporators supplied with liquid by either gravity flooding with surge drums or pumped overfeed either with mechanical pumps or discharge gas-driven vessels. This condition will be just.
