降低压缩空气中水蒸气含量的这两种方法也有助于降低压缩空气中的油含量。

Reduce the water vapor in the compressed air of the two methods can also help reduce the oil content of compressed air.

冷冻式空气干燥器通过降低压缩空气的温度至接近水的凝固点，使多余的水蒸气凝结成液体水，从而与气流分离。

Frozen type air dryer by lowering the temperature of compressed air to close to the freezing point of water, that extra water vapor condense into liquid water, thus and flow separation.

蒸发后的低温低压冷媒蒸气，从压缩机的吸气口流回，被压缩压缩后排出进入下一循环。

The vaporized refrigerant vapor from the low temperature and low pressure, suction inlet of the compressor to be compressed, compressed and then discharged into the next cycle.
