Dehumidifier can be divided into commercial dehumidifier and industrial dehumidifier and industrial dehumidifier fall into two categories, industrial cool dehumidifier and industrial warm dehumidifier. Besides, you can choose different kind of dehumidifiers according to different occasions. If you want to breathe fresh air at office, there is industrial humidifier for office for you and if you work in the basement, there is industrial humidifier for basement for you. If you are in constant movement, you can choose a portable dehumidifier and better, a mini portable dehumidifier.

 

The dehumidifier adjusts the humidity of the room by removing excess water from the air, thereby creating unsuitable living conditions for dust mites, mold and other allergic organisms. But how does the dehumidifier work? What is the mechanism that allows the dehumidifier to absorb moisture from the air as a gas and remove it as liquid water? Although there are two main methods for dehumidifiers to remove moisture from the air, in this article, we will focus on refrigerant-based dehumidifiers, which are the most popular dehumidifiers. So, how does the dehumidifier work? Continue reading to understand how the dehumidifier works!

 

Dehumidifiers, also known as dryers, can be generally divided into two categories: home dehumidifiers and industrial dehumidifiers, and belong to a member of the air-conditioning family. Generally, the conventional dehumidifier is composed of a compressor, a heat exchanger, a fan, a water container, a casing and a controller. Its working principle is: the fan draws humid air into the machine and passes through the heat exchanger. At this time, the water molecules in the air condense into water droplets, and the dry air is discharged out of the machine. This cycle keeps the indoor humidity at a suitable level.

The principle of refrigerant dehumidifier is actually very simple. Have you ever noticed how the water in the cold water cup is formed in hot weather? That's condensation. Once you know it, the working principle of dehumidifier becomes much easier.

 

Room dehumidifiers work like air conditioners. Warm, humid air is drawn in by fans. Then, the humid air passes over the refrigerant-cooled coil of the dehumidifier, causing moisture in the air to condense on the coil inside the machine. But why this happen?

 

Just like your glass of ice water, the coil is colder than the surrounding air. As the air cools, its ability to retain moisture decreases, and when the moisture in the air exceeds its capacity, a familiar condensate will form. Dehumidifiers usually have a water collection tray or a removable bucket in which condensed water can be collected for easy disposal. Some dehumidifiers are also equipped with a built-in pump that can continuously drain water without hassle. Next, the cooled air flows through the dehumidifier's heating motor, which reheats the air slightly before venting it back to the room. The dry and slightly warm air leaves the dehumidifier and attracts moisture like a magnet, thereby maximizing the efficiency of the dehumidifier.

The following is a breakdown of the steps taken during operation of the dehumidifier:

 

1. Air is drawn into the device through the fan.

 

2. The air passes through the cooled coil.

 

3. As the air cools, its moisture condenses.

 

4. Water falls into the drip tray or removable bucket.

 

5. Then, the air is reheated by the heat recovery system.

 

6. The air at 2 degrees Celsius and the dryer air returns to the room.

 

7. The defrost system will automatically deicing the equipment as needed.

 

8. After the drain bucket is full, the dehumidifier will automatically shut down, you do not need to worry

 

9. When the dehumidifier reaches the selected dryness indoors, it will automatically shut down.
