冷凝蒸发器为多层板翅，各通道中的冷热流体通过板翅和隔板进行良好的换热。冷凝蒸发器一般安置于上下塔之间，下塔上升的氮气在其内部被冷凝，而上塔回流的液氮在其内部被蒸发。这个过程得以实现主要是依据高压氮的沸点和低压氮的沸点不同，存在一定温差。冷凝蒸发器用于复叠式制冷机。
文中涉及了蒸发器、冷凝器、冷凝蒸发器、中间换热器、毛细管和压缩机的设计计算。
The design calculations of evaporator, condenser, condensing-evaporator, medium heat transfer, capillary and compressor are described.
氨经冷凝器后流入蒸发器，在这里它在被水再次吸收之前提供制冷效果。
The ammonia circulates through a condenser and then an evaporator, where it provides the cooling, before being reabsorbed by the water.
蒸发器有助于冷却空气，冷凝器帮助准备冷却过程中的制冷剂，压缩机有助于制冷剂在它们之间移动来回。
The evaporator helps cool the air, the condenser helps ready the system's refrigerant for the cooling process, and the compressor helps move refrigerant back and forth between them.
