Operating principle of industrial Dehumidifier
Impact of icing on industrial Dehumidifier
Although the industrial Dehumidifier can effectively remove excessive moisture in the air, when the ambient temperature drops to a certain extent, it may cause icing problems. This will cause the Dehumidifier to fail to operate normally, or even damage the equipment.
Icing principle of Dehumidifier
The use range of Dehumidifier is 5~38 ℃. If it exceeds this range, it will freeze. The principle is similar to air conditioning. Ice will start to form when the temperature is lower than 18 ℃, but the current Dehumidifier has the function of defrosting. It can work as long as the temperature is not lower than 5 ℃, and the dehumidification effect will be affected when the temperature drops to a certain extent.
If the Dehumidifier freezes, the water vapor will condense directly on the evaporator coil. The reason for this phenomenon is that the evaporation temperature is too low or the distance between the evaporator plates is too small. Generally speaking, the distance between evaporator blades meets the requirements, so the main reason is that the evaporation temperature is too low! The reason for the low evaporation temperature is the low evaporation pressure. Usually, an evaporation pressure regulating valve is added after the evaporator to maintain the evaporation pressure at a high level to increase the corresponding evaporation temperature. When the temperature in the evaporation environment is higher than the freezing point of water vapor and lower than its dew point temperature, the condensed water will not form ice.
Low temperature is one of the main reasons for freezing
Low temperature is one of the main reasons for industrial Dehumidifier icing. When the ambient temperature drops to a certain extent, the refrigerant will form frost or ice on the surface of the evaporator, which will affect the refrigeration effect and equipment life.
Insufficient air flow can also cause icing
Another cause of icing of industrial Dehumidifier is insufficient air flow. If the ventilation is poor or the installation position of the equipment is not suitable, it will cause poor air flow, resulting in the refrigerant staying on the surface of the evaporator for too long, ultimately forming frost or ice layer.
Regular cleaning and maintenance are required to avoid freezing
In order to avoid icing problem of industrial Dehumidifier, we need to clean and maintain it regularly. Especially for components such as evaporators and filters that are susceptible to dust and dirt, special attention should be paid to cleaning.
Choosing the appropriate Dehumidifier model and installation location can reduce the risk of icing
In addition, when purchasing and installing industrial Dehumidifier, attention should also be paid to selecting the appropriate model, and the equipment installation location should be considered. If problems such as low power, poor performance, or improper placement are selected, the equipment may be prone to icing.
How to solve the icing problem of industrial Dehumidifier
What if the industrial Dehumidifier icing problem has occurred? Firstly, it is necessary to stop using the equipment and promptly remove frost or accumulated water in the drainage pipeline. Subsequently, the problem can be alleviated by increasing indoor temperature, improving ventilation efficiency, and repairing or replacing relevant components according to specific circumstances.
In a word, in daily use and management, we need to pay attention to the maintenance of such important equipment as industrial Dehumidifier, and understand its common faults and solutions for timely treatment.
