经费筹措司的一系列冷冻压缩空气烘干机里

Refrigerated Compressed In accordance with the refrigeration and dehumidification principle, the Refrigerated Compressed Air Dryer (refrigerated dryer for short) makes use of the refrigeration device to cool the compressed air to certain dew point temperature, which separates out the moisture contained and discharge the moisture through the gas-moisture separator and drain device, thus to dry the compressed air. Commonly, the freeze-drying method can reduce the pressure dew point to 1.710. When the pressure dew point drops below 0, drainage will be blocked as the moisture separated out from the air gets frozen in the cooling device; therefore, it is generally not adopted.
