Principle and Precautions of Dehumidifying Dryer

Compared with ordinary hot air drying machines, dehumidifying dryers have the function of automatically controlling humidity to prevent excessive drying. Generally, drying machines still cause the target object to absorb moisture because they themselves contain moisture. Today, we will introduce to you the dehumidifying dryer, which has been widely used. Let's take a detailed look below.

Operating principle of dehumidifying dryer

Inner loop of dehumidifying dryer: The compressor operates→discharge port discharges high-temperature and high-pressure gas→enters condenser for cooling→becomes low-temperature high-pressure gas→flow is cut off by capillary tube→becomes low-temperature low-pressure liquid→evaporator evaporates and absorbs heat→returns to compressor to become low-temperature and low-pressure gas. This cycle is repeated.

Outer loop of dehumidifying dryer: In normal operation→the humid air is sucked in from the air inlet by the fan→flows through the evaporator→the evaporator adsorbs moisture on the aluminum sheet and turns it into dry air→through the condenser heat dissipation→blows out from the outlet.

Precautions for using dehumidifying dryer

The dehumidifying dryer should be cleaned frequently to keep it clean. The dehumidifying dryer should be placed in the center of the room. There should be no obstructions blocking the inlet and outlet of the refrigerated dryer, and the filter should be cleaned. When the ambient temperature is lower than 15℃, the water droplets attached to the surface of the evaporator will freeze and weaken the dehumidifying effect. If the ambient temperature exceeds 40℃, the system pressure will increase and overload the compressor, and the overload protection device should cut off the power supply, otherwise the compressor motor will be damaged. Therefore, the best temperature range for using a dehumidifying dryer is 15℃ to 40℃. If the humidity in the air is lower than 30%, it will be too dry and uncomfortable. A humidity controller can be used to maintain the range of 50% to 60%. When using the dehumidifying dryer, try to close the doors and windows to achieve the dehumidifying effect in the room. The body of the dehumidifying dryer should be placed flat, and cannot be tilted or placed horizontally, to avoid machine failure or abnormal noise.

When the water storage capacity inside the dehumidifying dryer is too full, to avoid overflowing and wetting the ground, please unplug the power plug during the movement of the machine and pour the water in the water storage bucket. After moving the dehumidifying dryer, it is best to let it stand still for four to six hours before using it again to allow the refrigerant in the compressor pipeline of the dehumidifying dryer to return to its original position. Clean the filter screen regularly (about once every two weeks) to maintain the dehumidification and dust removal efficiency and extend the life of the machine. Wash the filter screen with water below 40℃; it is better to use a cleaning agent to wash it, wash off the dust, rinse it with water, and air dry it before putting it back into the body of the machine.

When cleaning the body of the machine, wipe it gently with a damp cloth; avoid directly splashing water to clean it to avoid damaging the electrical insulation. If there are adhesives on the surface of the machine, use soapy water to clean them instead of using gasoline, petroleum spirits, solvents, or spray insecticides to avoid paint peeling or discoloration. Do not use a thin rod or iron wire to poke the inside of the machine to avoid malfunctions or danger. When not in use or going out for a long time, please unplug the power plug to maintain the life of the machine.

The dehumidifying dryer is also called a dehumidifier, and today we mainly introduced its principle and precautions for use. In fact, it is also very useful in our daily life, because many households have small household dehumidifying dryer. Dehumidifying dryer is composed of compressors, fans, and other components. The fan draws in air, and the heat exchanger condenses the moisture into water droplets and discharges them.
