Precautions and maintenance methods of dehumidifier: 1: The condenser should be cleaned frequently and kept clean. 2. The dehumidifier should be placed in the center of the room. The air inlet and outlet of dehumidifier should not be blocked by obstacles, and the air filter should be cleaned. When the ambient temperature is lower than 15℃, the water droplets attached to the evaporator surface will freeze, which will weaken the dehumidification effect. If the ambient temperature exceeds 40℃, the pressure in the system will increase and the compressor will be overloaded. At this time, the overload protector should cut off the line, otherwise it will damage the compressor motor. Therefore, the optimum working temperature range of dehumidifier is 5℃-38℃, and the working temperature range of microcomputer-controlled dehumidifier can reach 5℃-40℃ because of its automatic defrosting function. If the humidity in the air is below 30%, it will be too dry and uncomfortable. It can be controlled by the humidity controller to keep the humidity between 50% and 60%. 3. When using, try to close the doors and windows to improve the use effect of dehumidifier. The machine body should be placed in a flat place, and it should not be tilted or toppled, so as to avoid machine failure. When dealing with the dehumidifier, turn off the power first, and then pour out the water in the storage bucket. 4. When the dehumidifier is moving, it is best to let it stand for 4-6 hours before turning it on. Because the compressor and copper tube in the dehumidifier contain refrigerant, it takes 4-6 hours for the refrigerant to return to its original position after being moved. 5. Clean the air filter regularly (about once every two weeks) to keep the air inlet of the machine unblocked, ensure the dehumidification effect and prolong the service life of the machine. Clean the filter screen with clean water below 40℃: it is best to clean it with detergent, wash it with clean water after removing dust, and put it back into the body after drying in the shade. 6. When cleaning the fuselage, gently wipe it with a wet cloth. Do not splash water directly, so as not to damage the circuit and prevent short circuit. If there is adhesive on the surface of the machine body, clean it with soapy water. Do not use gasoline or solvent to avoid paint peeling or discoloration. 7: Don't dig out the inside of the machine with a thin rod or wire to avoid failure or danger. 8: Unplug the power supply when there is power failure or long-term non-use, and when traveling. Note: The above precautions and maintenance methods are applicable to dehumidifiers, dehumidifiers, industrial dehumidifiers, industrial dehumidifiers, Dongguan dehumidifiers, warehouse dehumidifiers, warehouse dehumidifiers and dryers.
The condenser should be cleaned frequently and kept clean. The dehumidifier should be placed in the center of the room. The air inlet and outlet of dehumidifier should not be blocked by obstacles, and the air filter should be cleaned. When the ambient temperature is lower than 15℃, the water droplets attached to the evaporator surface will freeze and weaken the dehumidification effect. If the ambient temperature exceeds 40℃, the pressure in the system will increase and the compressor will be overloaded. At this time, the overload protector should cut off the line, otherwise it will damage the compressor motor. Therefore, the optimum temperature range of dehumidifier is 15℃ ~ 40℃. If the humidity in the air is below 30%, it means it is too dry and uncomfortable, so it is ok.
It is controlled by the humidity controller and kept in the range of 50% ~ 60%. When in use, close the doors and windows as much as possible to achieve indoor dehumidification. The machine body should be flat, not inclined or toppled, so as to avoid machine failure or abnormal sound.
The dehumidifier is too full of water. In order to avoid overflowing and wetting the ground, when the machine body must be transported during operation, please unplug the power cord first, and then dump the water in the water storage bucket. It is best to keep the dehumidifier in a static state for four to six hours before starting, because the compressor pipeline in the dehumidifier contains cold coal, and after moving, the cold coal must return to its original position after four to six hours. Clean the air filter regularly (about once every two weeks) to maintain the dehumidification and dust removal efficiency and service life of the machine. Clean the filter screen with clean water below 40℃; It is best to wash with detergent. After washing away the dust, rinse with water, dry in the shade and put it back in the body. When cleaning the car body, gently wipe it with a wet cloth; Avoid splashing water directly for cleaning, so as not to damage the insulation of electrical appliances. There are adhesions on the surface of the body, which can be cleaned with soapy water. Avoid spraying them with gasoline, petroleum essence, solvent or spray insecticide to avoid paint removal or discoloration. It is not allowed to dig out the inside of the machine with thin rods and wires to avoid failure or danger. When there is power failure or long-term non-use or travel, please unplug the power cord to maintain the service life of the machine.

1. What is appropriate humidity control?
In spring and summer, when the relative humidity of the air is >; 60%, metal objects will rust, biological products will be moldy, paper products will become soft, and people will feel chest tightness. At this time, it is necessary to dehumidify.
Some special industries require low humidity. For example: glass laminate
Some special industries require high humidity. Such as: tobacco >; 60%, printing > 70%, textile > 65%, mushroom > 80%, aging test > 90%.
Second, why can't air conditioners replace dehumidifiers?
1. The dehumidification capacity of air conditioner is small, and the dehumidification depth is not as good as that of dehumidifier, because the power of air conditioner is mainly used for refrigeration, while the power of dehumidifier is mainly used for dehumidification.
2. Usually, the warehouse is not allowed to cool down and dehumidify, because after the goods are cooled down, they will come into contact with hot air during transportation, but they will be more humid. Air conditioning is a dehumidifier, which is used to cool and dehumidify.
It is flat temperature or slight heat dehumidification.
Third, the types of dehumidification methods
1. Freezing dehumidification: cooling the air below the dew point, and then removing the condensed water, which is effective when it is above the dew point. Such as: Matsushima SD series.
2. Compression dehumidification: It is effective for compressing, cooling and separating moisture in humid air in small air volume occasions, but not suitable for large air volume occasions.
3. Rotating wheel adsorption dehumidification: the thin plate impregnated with hygroscopic agent is processed into a honeycomb rotating wheel and ventilated. Its dehumidification structure is simple, and the dew point can reach -70℃ after special preparation.
Go down. Mainly used in glass, capsules, batteries, pharmaceuticals and other industries. Such as: Matsushima SD series.
Four, the parameters involved in humidity
1, wet bulb temperature (℃) The temperature measured by wrapping wet gauze on the temperature bag of the thermometer (i.e. the saturated state with relative humidity of 100%);
2. Dry bulb temperature (℃) The temperature measured by thermometer is not wrapped with wet gauze, and the temperature difference between dry bulb and wet bulb reflects the air humidity;
3. Dew point temperature (℃) cools the air in a certain state along the isohumidity line to the temperature when water condenses (that is, the relative humidity reaches100%);
4. Relative humidity (%) The saturation of water in the air is expressed by the ratio of the partial pressure of water vapor to the saturation pressure, and the larger the value, the wetter it is;
5, water content (g/ kg) grams of water vapor weight per kilogram of dry air;
