At the same time, it also has remote monitoring function, and management personnel can understand the real-time operation status of the equipment through their mobile phones or computers, which is convenient for maintenance and management.
Classified by working principle
1. Cooling, dehumidification and drying machine
-Features: The cooling dehumidification dryer cools the humid air through a cooling system. When the air temperature drops below the dew point temperature, the water vapor in the air condenses into water droplets, thereby achieving the purpose of dehumidification. This dehumidification method has mature technology and low cost, but the dehumidification effect is greatly affected by the ambient temperature.
-Application scenario: In environments with high temperature and humidity, the cooling dehumidification dryer has a more significant effect. For example, in some factories and workshops in tropical regions, the temperature is high and the humidity is also high in summer. Using a cooling dehumidification dryer can quickly reduce humidity and improve the working environment.
-For example, common household air conditioners have certain cooling and dehumidification functions. When the dehumidification mode of the air conditioner is turned on, the compressor inside the air conditioner starts working, and the refrigerant evaporates and absorbs heat in the evaporator, causing the surface temperature of the evaporator to decrease. When humid air passes through the evaporator, water vapor condenses into water droplets when cooled, and drips onto the water tray before being discharged outside, thus achieving the dehumidification effect.
2. Rotary dehumidifier dryer
-Features: The rotary dehumidifier dryer adopts a honeycomb shaped rotary wheel, and the surface of the rotary wheel is coated with moisture absorbent. When humid air passes through the impeller, water vapor is adsorbed by the moisture absorbing agent, and then the impeller slowly rotates. When passing through the heating area, the moisture in the moisture absorbing agent is heated and vaporized, forming dry air that is discharged. The dehumidification effect of the rotary dehumidifier is not affected by the ambient temperature and can work normally in low-temperature environments.
-Application scenarios: In some places with high humidity control requirements, such as laboratories, precision instrument manufacturing workshops, etc., rotary dehumidifiers and dryers are ideal choices. It can precisely control the humidity at a lower level to meet the needs of special processes.
-For example, a rotary dehumidifier dryer used in a laboratory can control humidity within an accuracy range of ± 5%. The wheel is made of special moisture absorbing material, which has strong moisture absorption ability. Even in environments with humidity as high as 90%, it can quickly reduce the humidity to the set value.
3. Lithium chloride dehumidification dryer
-Characteristics: Lithium chloride has strong deliquescence and can absorb a large amount of water. Lithium chloride dehumidification dryer uses lithium chloride solution as the moisture absorbing medium. When humid air passes through the lithium chloride solution, water vapor is absorbed, thereby achieving the purpose of dehumidification. This dehumidification method has efficient dehumidification capability, but requires regular replacement of lithium chloride solution.
-Application scenarios: In some industries that are extremely sensitive to humidity, such as lithium battery manufacturing, pharmaceutical production, etc., lithium chloride dehumidification dryers have been widely used. It can provide a stable low humidity environment for the production process, ensuring the quality and performance of the product.
-For example, a lithium battery production enterprise uses a lithium chloride dehumidification dryer that can control the humidity in the workshop below 1%. By precisely controlling the concentration and flow rate of lithium chloride solution, high-precision regulation of humidity has been achieved, providing reliable guarantees for the production and storage of lithium batteries.
Classified by functional characteristics
1. Heating type dehumidifier dryer
-Features: The temperature increasing dehumidification dryer can not only dehumidify, but also heat and increase the temperature of the air. This type of dehumidifier is suitable for cold and humid environments, as it can remove moisture from the air and increase indoor temperature, making the environment more comfortable.
-Application scenario: In winter in the north, when there is a need for both heating and dehumidification indoors, a temperature increasing dehumidifier dryer comes in handy. For example, in some old residential areas without centralized heating, residents can use temperature rising dehumidifiers to solve the problems of indoor humidity and coldness.
-For example, a certain heating type dehumidifier dryer has an independent heating module that can increase the air temperature by more than 10 ℃ during the dehumidification process. Users can adjust the heating temperature and dehumidification intensity according to their actual needs, achieving personalized humidity and temperature control.
2. Purification type dehumidification dryer
-Features: The purification type dehumidifier not only dehumidifies, but also comes with air purification function. It usually adopts a multi-layer filter structure, which can filter out small particles such as dust, pollen, bacteria, etc. in the air, providing users with healthier and fresher air.
-Application scenario: For people with allergies and places with high air quality requirements, such as hospital wards, kindergartens, etc., a purification type dehumidifier dryer is a good choice. It can effectively remove allergens and pollutants from the air, protecting people’s physical health.
