The lowest humidity that professional dehumidifiers and industrial dehumidifiers can achieve is RH10.
1. The lowest humidity that a refrigeration dehumidifier can generally reach is RH30; the lowest humidity that a rotary dehumidifier can reach is RH10.
2. Industrial dehumidifiers are very professional electromechanical equipment. People do not know enough about them. When selecting dehumidifiers, they often make simple selections based on the area of ??the place to be dehumidified. Air purification equipment with technological requirements such as industrial workshops and warehouses has strict requirements on its target humidity. Therefore, dehumidification equipment such as industrial dehumidifiers cannot be selected purely based on the area of ??the place of use. Specifically, it is calculated based on comprehensive factors such as its area, floor height, initial humidity value, target humidity value, indoor sealing degree, moisture source, fresh air supply, etc. After obtaining key parameters such as total cooling capacity and dehumidification capacity per unit time, select a dehumidifier.
3. Dehumidifiers are divided into refrigeration type and rotary type according to their working principles. The refrigerated dehumidifier uses a fan to draw humid air into the machine. After the interaction between the refrigeration system, it will form frost. The system will automatically heat up and defrost the water to flow into the water tank, producing dry air for discharge. This cycle will reduce the indoor humidity. The humid space gradually achieves a dry effect; the rotary dehumidifier is a turntable-type metal silica adsorbent that uses air solid adsorption. During the dehumidification process, the adsorption turntable slowly rotates driven by the driving device. When the adsorption turntable adsorbs water molecules in the air treatment area After reaching the saturated state, it enters the regeneration area and is desorbed and regenerated by high-temperature air. This process continues over and over again. The dry air is continuously temperature-regulated and then sent into the designated space to achieve high-precision temperature and humidity control.
4. The refrigeration dehumidifier has a compressor. When the ambient temperature is low (usually below 10°C), it will enter defrost regularly. During the defrost process, the compressor does not work and the dehumidifier No dehumidification. The rotary dehumidifier has no compressor and is not affected by the environment. Refrigerated dehumidifiers are moderately priced, and the dehumidifiers sold on the market are basically refrigerated dehumidifiers. Rotary dehumidifiers are very expensive and rare on the market. The dehumidification efficiency of refrigerated dehumidifiers is worse than that of rotary dehumidifiers.
5. Humidity is a physical quantity indicating the degree of dryness of the atmosphere. At a certain temperature, the less water vapor contained in a certain volume of air, the drier the air is; the more water vapor, the more humid the air is. The degree of dryness and humidity of the air is called "humidity". In this sense, it is often expressed by physical quantities such as absolute humidity, relative humidity, comparative humidity, mixing ratio, saturation difference, and dew point; if it represents the weight of water vapor in wet steam as a percentage of the total weight (volume) of the steam, it is called is the humidity of steam. RH is relative humidity, (Relative Humidity) is defined by dew point temperature. Humidity is defined as "the quantity of the physical state" in the Metrology Law. The humidity referred to in daily life is relative humidity, expressed as rh. In short, it is the percentage of the amount of water vapor (water vapor pressure) contained in a gas (usually air) to the amount of saturated water vapor (saturated water vapor pressure) if it is the same as air.
