How to customize the drying plan of a dehumidification dryer

When the overall products of domestic dehumidifier dryers enter the mature stage, their product profits are already very transparent. Faced with fierce competition, conventional dehumidifiers can only compete to lower prices. In addition to reducing production and operating costs, it is more important to segment the dehumidifier market, as dehumidifier companies are seeking a new wave of economic inflation.

When the relative humidity is the same, the higher the moisture content of the air, the higher the dry bulb temperature of the air. The increase in air treatment temperature will increase the temperature of the saturated air on the surface of the dehumidification wheel, thereby increasing the partial pressure of saturated water vapor, which is not conducive to air dehumidification; However, an increase in air moisture content will correspondingly increase the partial pressure of water vapor in the air, which is a favorable factor for dehumidification; Therefore, it is necessary to comprehensively consider the impact of the dehumidification process. It can be seen that in the cooling and air conditioning system of the rotary dehumidifier, the moisture content of the air as a measure of air humidity is accurate, and the moisture content directly corresponds to the dew point temperature of the air.

The lower the air flow rate, the longer the contact time between the air and the hygroscopic agent, and the more sufficient the heat and mass exchange between the two, but the smaller the amount of air processed per unit area. Increasing the air flow rate will increase the convective heat transfer coefficient and mass transfer coefficient, which is a favorable factor for convective mass transfer between air and hygroscopic agents; But the increase in wind speed also shortens the contact time between the two, which may cause the processed air to exit the wheel without effective dehumidification, which is unfavorable for dehumidification, and the air may not reach the predetermined humidity.
