We all know that the "humidity" of the air refers to the degree of dryness of the air, that is to say, the air already contains water.
Air compressor does not produce water, but in the process of compressed air, by the way when the water "Porter.". When the air in natural state is compressed or cooled, it will tend to be saturated until it is supersaturated, and the water in the air will be separated out from the gas state to the liquid state, thus the water will be produced.
For compressed air system, compression is its purpose, and cooling starts from compression.
When the air compressor is working, the internal temperature of the compressor head is very high (about 100 ℃) because the gas is compressed to release a lot of heat. The water in the natural air inhaled will form water vapor during the compression process of the air compressor, which will be discharged with the compressed air.
Generally, the air cooler is equipped in the air compressor unit to force cooling of the compressed air to be discharged from the air compressor. The purpose is to remove part of the water in the compressed air by cooling and condensation.
This is the air compressor itself cooling drainage function sound case, otherwise, compressed air and water flow to the rear end of the pipeline.
Even if the drainage function of the air compressor body is normal and there is no liquid water at the outlet of the air compressor, the discharged compressed air is still saturated. With only a little cooling, the compressed air will still condense out liquid water.
The "back to the South" in the South directly shows the formation of water. When warm and humid air meets the surface of objects with lower temperature, such as floors and walls, water droplets will condense on the surface.
