在冻结装置中,有一种特殊形式的重力供液即满液式供液,它是将氨液分离器与蒸发器设在同一层上,利用液体的均压作用,使氨液分离器和蒸发器内液面趋向一致,它的液面高度保证排管容积的60～80％存有液体。其优点是可以免除重力供液系统中静液柱压力对蒸发压力的影响,保证系统达到所设计的蒸发温度,同时可以节约建筑投资。 在满液式供液系统中,氨液分离器必须靠近蒸发器,所以,目前在冻结库中,一般采用将氨液分离器设置于冻结间内的方案。在冻结间内氨液分离器是否需要做
In the freezing device, there is a special form of gravity for the liquid that is filled with liquid, it is the ammonia separator and the evaporator on the same layer, the use of liquid pressure equalization, the ammonia separator and evaporation The liquid level in the instrument tends to be consistent. Its liquid level ensures that 60-80% of the discharge volume is in liquid form. The advantage is that the influence of the hydrostatic column pressure on the evaporation pressure in the gravity feeding system can be avoided, the system can reach the designed evaporation temperature, and the construction investment can be saved at the same time. In the liquid-filled liquid supply system, ammonia liquid separator must be close to the evaporator, so the current freeze in the library, the ammonia separator is generally used in the program set in the freezing room. Ammonia separators in the freezing room need to be done
