Judgment and treatment of simple failure of dehumidifier!

Check that the ventilation system components of dehumidifier are air inlet grille, air outlet grille, air filter, evaporator, fan motor and blades. The damage of the grille is generally an aging phenomenon, which seriously hinders the intake or exhaust of air and affects ventilation. It is easier to check the air filter. See if it is damaged or blocked by dust. If there is dust, clean it in time. Check the evaporator mainly to see if there is ice and dust on the surface. The detection methods of fans and blades are similar to the most commonly used fans in our family, so I don't need to elaborate. It is worth noting that the loosening of screws can not be ignored. The blades of small dehumidifiers sometimes accumulate dust, which seriously blocks the blades. Check the fault of electrical system mainly includes three states: compressor and fan are not working; The compressor is not working and the fan is normal; Both the compressor and the fan are running, but the cooling has failed. If there is such a problem in the body, first of all, it depends on whether the power supply is broken and whether there is a problem with the switch. If there is nothing wrong with the power supply and switch, only ask the seller for help, and they will send professionals to provide after-sales service for you. Failure of refrigeration system, compressor, refrigeration system and compressor will also lead to no dehumidification. For example, our ordinary customers can't do anything about professional faults such as all the refrigerant leaks, the refrigeration system is blocked, and the compressor has no displacement.

What should I do if the noise of dehumidifier becomes bigger? There are many reasons for the noise. Uneven ground leads to unstable placement of dehumidifier, loose parts or foreign bodies in the fuselage, and damage or deformation of fan blades leads to dynamic balance damage; Starter failure, pipeline (copper pipe) collision, fan oil shortage; Excessive fan bearing wear, or excessive compressor noise, and excessive refrigerant or lubricating oil filling, resulting in corresponding liquid hammer. Specific problems need actual inspection to determine. Replace the accessories to stabilize the dehumidifier, fasten the parts on the dehumidifier, and remove the foreign bodies in the dehumidifier. Replace the damaged fan blades or deformation with new ones, and lubricate the fan bearings to reduce noise. If the gasket absorbs sound and wants to reduce the noise generated when the compressor is running, it is advisable to put a thick cloth or cork pad under the machine body to absorb the sound source and reduce the noise generated during operation.

The difference between dehumidifier dehumidification and air conditioning dehumidification!

Principle of air-conditioning dehumidifier: air-conditioning refrigeration dehumidification principle. In the refrigeration process, the temperature of wet air drops through the evaporator condenser, and the air humidity reaches a supersaturated state. The excess water vapor will become condensed water, which will condense on the aluminum fins of the evaporator and become water droplets to be discharged outside. However, when the cooling and refrigeration mode of the air conditioner reaches a balance, there will be no excess water precipitation, which is equivalent to saying that this dehumidification mode is an incidental function of air-conditioning refrigeration, which can remove part of the humidity, but has dehumidification ability.

The other is the independent dehumidification of air conditioners in non-cooling mode, that is to say, dehumidification mode can also be seen in some air conditioners' remote controllers. The working principle of air conditioning dehumidification mode is to heat the air cooled by air conditioning to the original temperature and then send it indoors. At this time, the air conditioning fan has been running at a low speed, the compressor is turned on and stopped, and the whole refrigeration system is interrupted. Most of the generated refrigeration capacity is used to balance indoor air and convert humid air into condensed water, and a small part of it is used to balance damp heat and reduce indoor temperature. This continuous cycle removes moisture from the air. Air conditioning needs cooling and dehumidification, and it does two jobs at the same time. The dehumidification effect cannot be compared with that of dehumidifier.

Working principle of the dryer: The working principle of the dryer is to use the moisture in the air to condense into frost when it enters the evaporator of the dryer, and then the condensed droplets are discharged outside, so as to reduce the air humidity. Dehydrator is a special equipment for dehumidification, which can quickly control the humidity within the required range, thus saving electricity. The working mode of dehydrator is to cool down inside the dehydrator and analyze the water, which has good precipitation effect and low power consumption, while the air conditioner cools down indoors, and the precipitation effect will be worse. The dehumidifying function of air conditioners is limited. In the rainy season, about 70% of water is usually removed, so it can't be reduced moderately, while ordinary freezing dehumidifiers can remove about 45%.
