Automatic coating equipment is a machine that can coat metal or non-metal materials with a lot of automation efficiency. When using automatic coating equipment, sometimes there are certain requirements for the humidity of the automatic coating equipment , The humidity is too high, you need to dehumidify. So what are the methods of dehumidification?
1. Cooling and dehumidifying method. When the air is cooled below the dew point temperature, the water vapor in the air will condense into water. Remove the condensed water and reheat it to get low-humidity air. The cooling source can use the refrigerant of the freezer, ice water. It belongs to the characteristics of reducing enthalpy, lowering humidity and lowering temperature.
A: When the surface temperature of the cooling coil is lower than zero degrees Celsius, the condensed water freezes on the surface of the coil, and the cooling efficiency is reduced, causing the automatic coating equipment to fail to obtain a stable temperature.
B: In general use, the limit of cooling and dehumidification is above zero degrees Celsius of the dew point temperature. If the automatic coating equipment is enlarged, it will increase power consumption and increase operating costs.
Two: Compressed dehumidification method. When the compressed air is cooled again, the moisture in the air will condense into water, and the condensed water will be removed and heated again to obtain low-humidity air.
The above is all of today's content. I believe everyone has a certain understanding of the dehumidification methods of automatic coating equipment. If you want to know more about automatic coating equipment related issues, please feel free to contact us.
